The application of titanium-zinc sheet roofing/wall materials has a history of more than a century. It is more commonly used in large European cities, such as Paris in France, London in the United Kingdom, Rome in Italy and other cities. Many buildings use titanium-zinc sheets. As a roofing material.
The titanium-zinc plate for roof/wall is smelted with high-purity metallic zinc (99.995%) that meets the European quality standard EN1179 and a small amount of titanium and copper. The titanium content is 0.06%-0.20%, which can improve the creep resistance of the alloy. Denaturation, the content of copper is 0.08%-1.00% to increase the hardness of the alloy. Zinc is an excellent durable metal material with natural corrosion resistance. A dense passivation protective layer can be formed on the surface, so that zinc maintains a very slow corrosion rate. Experimental testing and tracking show that the corrosion rate of zinc is less than 1 micron/year, and the 0.7mm titanium zinc plate can be used for nearly 100 years. The wound can be recovered automatically, the wound surface can recover 0.001μ within one day, the thickness can rise to 0.005μ after one day, and to 0.01μ after 20 days. All self-preserving metals can maintain the luster of the metal for a long time.
The thickness of the titanium-zinc plate for roof/wall is 0.5～1.5mm, and the density is 7.18g/cm3. For example, the 0.82mm-thick titanium-zinc plate roof weighs only 5.7kg/m2, which is an extremely lightweight roofing material. There is basically no effect on the roof structure.

Titanium-zinc plates for construction should meet the EN988 standard:
0.2% yield strength: >100N/mm2
Tensile strength: >150N/m2,
Elongation at first break: 35%,
Creep resistance (50N/mm2 force for one hour): <0.1%<><0.1%<><0.1%><0.1%><><0.1%<><><0.1%<><>

Elastic modulus: 90Kmpa in longitudinal direction, 110KmPa in transverse direction, with an average of 100KmPa.
Poisson's ratio: 0.25

The applicable slope of the titanium-zinc plate is 3 to 90 degrees, and zinc plates can be used for almost all kinds of slopes from very low slopes to vertical slopes. The width of the pure zinc roof panel is 430mm, the length is the longest 15 meters on the roof, and the longest wall is 4 meters. There are many fixing methods, the connecting plate and the two-layer zinc plate are folded together to be occluded; the joints can achieve a good waterproof effect without any treatment.
In addition to pure zinc plate roofing materials, some zinc alloy roofing materials have also begun to be applied in recent years and have achieved success. For example, zinc roofing materials containing titanium will generate a relatively dense and insoluble protective layer of zinc bicarbonate when exposed to atmospheric erosion, or generate a protective layer of zinc oxychloride under the action of sea air. This feature makes it extremely weather-resistant and does not require maintenance.

Titanium zinc plate-storage recommendations for titanium zinc plate
In order to ensure product quality, please strictly follow the following storage recommendations:

1. Plates and coils must be stored in a well-ventilated, dry and cool place with a constant temperature with sheltering measures to avoid condensation.

2. Plates and coils must be isolated from the ground with wooden frames to form sufficient air circulation space.

3. In order to ensure that the material is not deformed, all the plates must be placed flat on the shelf.

4. In the process of coil transportation, according to customer requirements, the material can be placed along the horizontal axis or the vertical axis.

It is recommended to store the coils in the original packaging. If you need to stack because of insufficient space, please follow the following principles:

1. If the coil is shipped and placed along the horizontal axis, the wooden frame must be stored separately in the original way and cannot be stacked.

2. If the coils are shipped along the longitudinal axis, the wooden racks can be stacked. Considering stability and safety, up to 5 can be stacked.

3. The storage time of plates and coils should be as short as possible, especially on construction sites.

1.4 Implementation standards
J is manufactured in accordance with the European standard EN1179 "Zinc and Zinc Alloy—Original Zinc" zinc sheet, the highest grade GRADE　Z1, which complies with EN1179/BS3436 specifications for the classification and chemical composition of zinc, and is controlled by EN988. To
Titanium zinc plate-zinc-titanium alloy (also known as titanium-zinc alloy or titanium alloy)
99.95% Zn pure zinc plus 0.8-1.0% Cu uranium improves its strength and 0.06-0.2% ti titanium reduces its creep rate, that is, a new generation of zinc-titanium alloy is synthesized; the use of zinc metal in the past 200 years is easy to bend, shear and weld, etc. The characteristics are limited to the manufacture of roof gutters and drainage pipes. To
The new generation of zinc-titanium alloy takes its weather resistance, high plasticity and color characteristics of synthetic oxide film, and is gradually accepted by designers as general civil building roofing and exterior wall decoration materials. The shortcomings of its inability to withstand moisture must be solved by a special roof replacement system. To
Titanium zinc plate-the characteristics of titanium zinc alloy:
1) The titanium-zinc plate is exposed to the atmosphere, and its surface forms a natural protective layer of light gray or blue-grey patina zinc carbonate layer to protect the zinc metal from corrosion and ensure the titanium-zinc metal plate has an excellent service life. To
2) Titanium-zinc plate is a self-preserving metal, which can automatically heal scratches on the surface layer. If the surface scratch depth is 0.01mm, it can heal after 20 days. It can maintain the metallic luster after long-term use and has a long life without coating protection. To
Key points of design selection
1) Bending radius: only when the radius of curvature is less than 10m, it needs to be pre-formed in the factory. The minimum radius of the pre-formed in the factory is 0.5m.
2) Service life
(1) On a flat roof with a drainage slope of 3°, the annual loss of the surface layer is an average of 4μm, 0.7mm thick titanium-zinc plate, considering its half-thickness factor, the service life is about 80-100 years. To
(2) In the case of vertical drainage (such as curtain walls), the annual surface layer loss is less than 1~2μm, and the service life can reach 200 years under the condition of completely maintenance-free.
