    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. 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.

    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.
