Square Metal Roofing Tile

Metal roofing refers to a roofing system that uses metal sheets as the roofing material, integrating the structural layer and waterproofing layer into one. There are many types of metal sheets, including galvanized sheets, aluminized zinc sheets, aluminum-magnesium-manganese alloy sheets, aluminum-magnesium alloy sheets, titanium-zinc alloy sheets, copper sheets, and stainless steel sheets. The surface of the sheets can be painted, primarily with four types of finishes: PE/PE, SMP/PE, HDP/PE, and PVDF/PE. Painting can extend the lifespan of the sheets to 5-8 years, 10-15 years, 15-20 years, and 20-25 years or more, respectively. The tile-locking system opens up a whole new world of architectural innovation. The optical effects produced by this system are particularly noticeable on large-area curtain walls. The layout of the tiles directly affects the visual effect, so this system primarily uses a vertical or near-vertical installation direction; vertical lines enhance the upward extension of the building, while horizontal joints strengthen the building's structural sense of being deeply rooted in the ground. Clearly, the architect's highly creative concept can lead our vision to another level. The tile series includes square and diamond shapes; unlike wooden shingles with similar visual effects, they have a raised edge on the front and a concave edge on the back, making them easy to connect. The tiles are factory-manufactured. Their special specifications can accommodate almost any curved shape, achieving a reliable and visually appealing effect even for buildings with complex geometries. Common application areas include roof windows, chimney tops, and building roof edges. The tile system is popular not only for roofs but also for curtain walls. The tile system can create unforgettable visual landscapes, providing designers with a wide range of choices. Flatlock roofing systems are versatile, high-quality roofing systems that, in addition to being completely unaffected by external weather conditions, offer the following advantages: Strong sense of layering and striking visual effect, classical architectural style; Easy installation, fixed to the underlying support structure with fasteners; Suitable for installation on any shape of building surface, achieving diverse architectural geometry; Suitable for pitched roofs and walls with an angle of ≥30°; Provides thermal insulation, sound absorption, and noise reduction functions.

Titanium-zinc roofing/wall materials have been used for nearly two centuries and are widely used in major European cities such as Paris, London, and Rome. Many buildings in these cities use titanium-zinc roofing materials. Their application in Asia is also developing rapidly.

Evolution of the passivation layer (Platina) Metallic zinc is highly reactive, readily reacting with water, oxygen, carbon dioxide, and other substances in the air under natural conditions. The resulting compounds form a dense, stable substance—the passivation layer. This passivation layer effectively protects the titanium-zinc sheet while preventing secondary contact and reaction between the zinc and air. Even if the passivation layer is damaged by external forces, the exposed zinc will still react with water, oxygen, carbon dioxide, and other substances in the air, eventually forming a new passivation layer identical to the original. Therefore, its lifespan, color stability, and self-healing capabilities are fully demonstrated. The chemical equilibrium of the passivation layer varies depending on environmental factors (air pressure, humidity, temperature, oxygen content, carbon dioxide content, etc.). Therefore, each titanium-zinc sheet building possesses its own unique natural vitality (e.g., in the water-rich environments of southern my country, the gray color may slightly change). Material characteristics a. Long service life: the metal surface layer has a lifespan of 80-100 years; b. Protected by its own zinc carbonate protective layer, it prevents further corrosion, requires no painting, has a true metallic texture, and features self-healing after scratches, leaving no marks and requiring no maintenance; c. The panels have good elongation and tensile strength, good plasticity, and can be bent into three-dimensional and irregular shapes on-site, fully satisfying the rich creative imagination and inspiration requirements of owners and architects; d. Concealed snap-fit ​​vertical edge interlocking joints and flat locking (diagonal locking) joints form a structural waterproof and dustproof system. The roof joints are lightweight and aesthetically pleasing, with excellent waterproofing, especially effective against typhoons and severe weather in coastal areas; e. Leveraging 200 years of accumulated experience and technology in roof system construction, and utilizing modern roof construction equipment, the construction of this roof system is safe, economical, fast, and accurate. Titanium zinc plate material is available in three different colors: raw zinc (similar to stainless steel) and pre-passivated zinc (which has undergone pre-passivation treatment, and the surface has formed two types of protective films: blue-gray and copper-green). Maintain 1. Fingerprints: When titanium-zinc panels are used in curtain walls, fingerprints should be avoided. Mineral oil is needed to remove them. Of course, to prevent fingerprints altogether, it's best to wear cotton gloves during installation. 2. Grease and Dust: If grease and dust accumulate on the surface of the titanium-zinc panels during installation, gently wipe them off with a clean, dry cloth. Do not scrub vigorously or use cleaning products. Dust can be washed away naturally by rainwater. 3. Surface Scratches: If small surface scratches appear on the titanium-zinc panels during installation, a new passivation layer will regenerate due to the self-healing properties of the passivation layer. However, if the scratches are deep and wide, replacement of the panel should be considered. 4. Protective Film: To prevent scratches during transportation and installation, titanium-zinc panel manufacturers apply a protective film to the surface of the products. This film should be removed as soon as possible after installation. It is recommended that the protective film be removed within 6 weeks of the installation completion date. Storage Recommendations To ensure product quality, please strictly adhere to the following storage recommendations: 1. Sheets and rolls must be stored in a well-ventilated, dry, cool, and sheltered temperature-controlled area to prevent condensation. 2. Sheets and rolls must be isolated from the ground using wooden racks to ensure sufficient air circulation. 3. To prevent material deformation, all sheets must be laid flat on the racks. 4. During roll transportation, materials can be placed along either the horizontal or vertical axis, depending on customer requirements. It is recommended to store rolls in their original packaging. If stacking is necessary due to space constraints, please follow these principles: 1. If the rolls arrive in a horizontal orientation, the wooden racks must be kept separate as before and cannot be stacked. 2. If the rolls arrive in a vertical orientation, the wooden racks can be stacked, but for stability and safety, a maximum of 5 racks can be stacked. 3. The storage time for sheets and rolls should be minimized, especially at construction sites. Titanium-zinc steel sheets are a green material that is 100% recyclable and reusable, aligning with sustainable development principles. The use of titanium-zinc steel sheets has no adverse effects on the surrounding environment. Water runoff from the zinc sheet surface can be used to water plants without any side effects. Zinc is a completely natural material, widely found in nature, and is an essential element for humans and other organisms, playing a vital role in biological balance and growth.

Roof waterproofing is an extremely important aspect. Standing seam metal roof panels themselves have excellent waterproofing properties, but some metal roofs still experience leaks during use. There are many factors that cause leaks in metal roofs. During installation, different workers' techniques and the building structure can lead to varying installation results. So, what are the main causes of roof panel leaks, and what are the corresponding solutions? Generally, the main factors to consider regarding the self-waterproofing performance of a roofing system include the connection method of the aluminum-magnesium-manganese roof panels and the edge finishing methods of the supporting systems. Roof leaks are mainly prominent at: the ridge, the connection points of the metal roof skylights, roof openings, the connection between the gable wall and the roof, and the interior gutters. I. Causes of Leaks1. Large roof curvature, roof panels not perpendicular to the building columns. The joints of standing seam metal roof panels are weak points, and these joints affect both the waterproofing quality and the strength of the roof panels. 1. Unprofessional construction techniques can easily lead to leaks. 2. Excessive segmentation and lack of slope in the gutter installation of standing seam metal roof panels. Insufficient slope causes water accumulation during rain or snow, corroding the roof and causing leaks. 3. Excessive spacing between the alloy supports of standing seam metal roof panels leads to uneven stress on the roof, causing deformation and leaks. 4. Inexperienced operators of edge-trimming machines during installation of standing seam metal roof panels can result in improper edge trimming and leaks. 5. For connection points such as gable walls, some construction workers simply connect the flashing to the outermost rib of the roof panel with self-tapping screws. These screw holes inevitably penetrate the roof, causing leaks if the seal fails. 6. Excessive deformation during welding of water pipes to the gutter can cause localized bulges and water accumulation. 7. Improperly secured roof panels and an inadequate drainage system design. II. Countermeasures Waterproofing standing seam metal roofs is a crucial measure. Besides paying attention to installation techniques, thorough preparation before installation is essential. 1. Carefully inspect the metal roof before construction to ensure it is secure, clean, and free of debris. 2. Identify areas requiring waterproofing: Areas requiring waterproofing for standing seam metal roof panels generally include horizontal overlaps, vertical overlaps, fan vents, pipes extending from the roof, air conditioning ducts, the perimeter of skylights, gutters, ridges, junctions between metal panels and parapet walls, and screw fasteners – weak points in the waterproofing of the metal roof. 3. Select T-shaped clamps compatible with the roof panel specifications. Place the T-shaped clamps in the appropriate positions to prevent damage to the standing seam metal roof panels during clamping. 4. Check the straightness and flatness of the T-shaped clamps to ensure they are on a horizontal line. 5. Preheat the surrounding area before welding gutters to reduce welding deformation and protrusions. Control the error within 2mm. Strengthen post-weld inspection and grinding. 6. Adjust the slope to ensure smooth drainage. 7. Avoid stepping on or deforming aluminum-magnesium-manganese roof panels during installation. Note the installation method at some key points: For the gable wall, first, fix the prefabricated aluminum alloy gable wall fastener to the roof panel ribs with rivets. Then, use gable wall fasteners to secure the fastener to the mounting base, thus firmly fixing the fastener. Next, attach the prefabricated T-shaped adjustable fastener to the fastener. Finally, fix the gable flashing to the T-shaped adjustable fastener with rivets. Since the exposed rivet holes do not penetrate the roof panel, there will be no gaps. The gable wall construction involves first fixing the prefabricated aluminum alloy gable wall groove to the roof panel ribs with rivets, then securing the groove to the fixing base using gable wall fasteners. This firmly secures the groove. Next, a prefabricated T-shaped adjustable groove is inserted into the gable wall groove. Finally, the gable flashing is fixed to the T-shaped adjustable groove with rivets. Since the exposed rivet holes do not penetrate the roof panel, there will be no leaks. Leakage at the ridge is mainly due to rainwater backflow. Inadequate sealing under the ridge cap can easily cause leaks. Insufficient connection strength of the ridge cap, leading to connection failure under thermal expansion and contraction, is another cause of leakage. ① Install metal plugs matching the roof panel type under the ridge cap;② The connection between the flashing at the intersection of the ridge tiles and the aluminum-magnesium-manganese roof panel should use an overlapping connection, with an overlap length not less than 200mm. ③ The overlap between the ridge tile and the aluminum-magnesium-manganese panel should not exceed 50mm, as a large distance will affect the windproof effect. During construction, ensure the gutter slope is corrected immediately during the construction process to reduce accumulated deviations and ensure smooth drainage. When welding the gutter, preheat the surrounding area to reduce welding deformation and protrusions, keeping deviations within 2mm. Improve the inspection and polishing work after welding. When installing metal roofing, it should be done under the guidance of professionals. Leaks in aluminum-magnesium-manganese metal roofs can be very troublesome, so waterproofing is a crucial step in the construction of vertical joint metal roofs. The construction method is very important; a professional construction team should be selected.

Metal roofing refers to a roofing system that uses metal sheets as the roofing material, integrating the structural layer and waterproofing layer into one. There are many types of metal sheets, including galvanized sheets, aluminized zinc sheets, aluminum alloy sheets, aluminum-magnesium alloy sheets, titanium alloy sheets, copper sheets, and stainless steel sheets. The surface of the sheets can be painted, primarily with PE/PE, SMP/PE, HDP/PE, and PVDF/PE coatings. Painting can extend the lifespan of the sheets to 5-8 years, 10-15 years, 15-20 years, and 20-25 years or more, respectively. The thickness is generally 0.4–1.5 mm, and the surface of the sheets is usually coated. Due to differences in material and coating quality, some sheets can have a lifespan of over 50 years. The sheets come in various shapes and sizes; some are composite sheets, where an insulation layer is laminated between two layers of metal sheets, while others are single-layer sheets. During construction, some sheets are prefabricated in the factory and assembled on-site, while others are fabricated on-site according to the needs of the roofing project. The insulation layer can be pre-laminated in the factory or fabricated on-site. Therefore, metal sheet roofing comes in various forms and is used in everything from large public buildings to factories, warehouses, and residences. The regulations stipulate that metal sheet roofing is applicable to roofs with waterproofing grades I to III. The main materials used for metal roofing include: aluminum-magnesium-manganese sheets, titanium-zinc sheets, bronze, and stainless steel sheets. 1. Aluminum sheets are alloy materials made by hot rolling aluminum, magnesium, and manganese in a certain proportion. The constituent elements determine the material's characteristics, which in turn determine its applications. 2. Titanium-zinc sheets are zinc-copper-titanium alloy sheets. Their main component is zinc, with small amounts of copper and titanium added. The titanium content ranges from 0.06% to 0.20%. The addition of titanium improves the alloy's resistance to deformation, preventing it from weakening its strength after thermal expansion and contraction, and also enhances its corrosion resistance. Titanium-zinc alloys offer performance superior to traditional zinc products in terms of mechanical strength, thermal resistance, and coefficient of thermal expansion. Compared to other metal roofing and curtain wall materials used in construction, titanium-zinc steel sheets offer superior corrosion resistance and lifespan compared to galvanized steel sheets and aluminum alloy sheets. They also feature a gray/blue-gray appearance with a biomimetic, self-healing surface, and excellent overall cost-effectiveness. Therefore, titanium-zinc steel sheets demonstrate significant advantages as interior and exterior wall and decorative materials for public buildings (especially landmark buildings), such as airports, convention centers, theaters, stadiums, high-end residences, and high-end office buildings. 3. Copper: Copper accounts for approximately 0.006% of the Earth's crust, currently estimated to be the 23rd most abundant metal. Copper and gold are colored metals. Due to its high corrosion resistance, ease of processing, and unique, natural appearance, copper sheets are highly suitable as roofing and wall materials. 4. Stainless Steel: Stainless steel is short for stainless and acid-resistant steel. Steels resistant to weak corrosive media such as air, steam, and water are called stainless steel; while steels resistant to chemical corrosion are called acid-resistant steel.

Metal roofing refers to a roofing system that uses sheet metal as the roofing material, integrating the structural layer and waterproofing layer into one. There are many types of metal sheets, including galvanized steel, aluminized zinc steel, aluminum-magnesium-manganese alloy steel, titanium-zinc alloy steel, copper steel, and stainless steel. The surface of the sheets can be painted, primarily with PE/PE, SMP/PE, HDP/PE, and PVDF/PE finishes. Painting can extend the lifespan of the sheets to 5-8 years, 10-15 years, 15-20 years, and 40-50 years or more, respectively. Factors to consider in metal roof design: Load-bearing capacity: Bearing construction loads, rainwater, dust, snow pressure, and maintenance loads. The load-bearing capacity of the metal roof panel is related to the cross-sectional characteristics of the panel type, the strength and thickness of the material, the load transfer method, and the spacing of the purlins (sub-purlins). Wind resistance: Resisting the maximum local wind pressure; the metal roof panel will not be pulled off by negative wind pressure. Wind resistance is related to the fastening force between the metal roof panel and the fixing brackets, and the spacing of the fixing brackets. Sound insulation: Preventing sound from the outside to the inside or vice versa. Sound insulation material (usually thermal insulation cotton) is filled inside the metal roof layer. The sound insulation effect is expressed in decibels as the sound intensity difference between the two sides of the metal roof layer. The sound insulation effect is related to the density and thickness of the sound insulation material. Note: Sound insulation materials have different blocking effects on different frequencies of sound. Waterproofing: Preventing rainwater from seeping into the metal roof panel from the outside. Rainwater mainly enters the metal roof through overlaps or joints. To achieve waterproofing, concealed fixing is required after using sealing washers at screw holes. Overlapping panels should be sealed with sealant or welded, ideally using continuous panels to eliminate overlaps. Thorough waterproofing treatment should be applied to all joints. Lightning Protection: Lightning should be diverted to the ground, preventing it from penetrating the metal roof and entering the interior. Lighting: Skylights improve indoor lighting during the day, saving energy. When installing skylights or translucent panels at specific locations on the metal roof, the lifespan of the skylights should be considered in conjunction with the metal roof panels. Waterproofing treatment should be applied at the joints between the skylights and the metal roof panels. Safety Devices: Fixed facilities should be installed on the metal roof to protect the safety of construction and maintenance personnel. Icicle Prevention: Icicles should be prevented from forming at the eaves due to rain and snow. Temperature Expansion and Contraction Control: The contraction displacement and direction of the metal roof panels should be controlled. This ensures that the metal roof panels will not be damaged by stress caused by thermal expansion and contraction in areas with large temperature differences. Insulation: Heat should be prevented from transferring between the sides of the metal roof, stabilizing the indoor temperature. Thermal insulation is achieved by filling the metal roof panels with insulation materials (commonly glass wool or rock wool). The insulation effect is expressed as the U-value, measured in W/m²K. Insulation performance is determined by the following factors: the raw materials, density, and thickness of the insulation material; the humidity of the insulation material; the connection method between the metal roof panels and the underlying structure (to prevent "cold bridging"); and the metal roof's ability to repeatedly absorb heat radiation. Sound absorption: Reduces sound reflection and lowers indoor echoes. Sound absorption is achieved by laying sound-absorbing cotton at the bottom of the metal roof and punching holes in the base plate. The sound absorption performance of the metal roof is expressed as the sound absorption coefficient α. Moisture control: Prevents water vapor condensation within the metal roof base and top layer, and removes moisture from the metal roof layer. Solutions include filling the metal roof layer with insulation cotton, laying a waterproof membrane on the metal roof base plate, and having ventilated joints in the metal roof panels. Fire resistance: In the event of a fire, the metal roof material will not burn, and flames will not penetrate the metal roof panels. Ventilation: Air exchange between indoors and outdoors. Ventilation openings are installed on the metal roof. Avalanche Prevention: Snow railings are installed on metal roofs in snowy areas to prevent sudden snow runoff. Maintenance: Facilitates maintenance of the metal roof throughout its service life, reducing maintenance costs.
