Aluzinc Sheet
Since the beginning of the nineteenth century, Zinc and Aluminium in Europe has been one of the favourite building materials due to its strong corrosion resistance, easy processing, both classical beauty and no lack of modern colour. Zinc is an eternal building material. Many European cities’ buildings are covered by the Aluzinc Roofing, while some world-renowned architects often have a soft spot for Aluzinc.
Aluzinc sheet is an ideal building materials, whether renovated or new projects, traditional or avant-garde design, can meet the aesthetic appearance of the building and practicality. As roofing and curtain wall materials, 85% of roofs in Paris, France are using Titanium Zinc materials. Galvalume roofing sheets has repeatedly appeared in the film, photography and painting works of art. Aluzinc steel sheet has become a symbol of modern Paris. In recent years, in the USA,Australia and Asia, from the private housing to public buildings, such as airports, opera houses, convention centers, stadiums and museums, can be seen in the figure of Aluzinc sheet.
Aluzinc coil is made of high quality Zinc with purity up to 99.99%. It is made of precise quantity of Copper and Titanium, which greatly improves the processing and mechanical properties of Zinc and the quality is more excellent. After pre-passivation treatment, its surface presents a variety of tone of the gray, and all building materials can coordinate co-exist. Its raw material life of up to 80 years – 100 years, so that people own confidence on the outlook of AZ Materials.
99.995% Zinc with a small amount of Aluminum smelting, the Aluminium content is about 0.06% -0.20% wich can improve the resistance of the steel plate Creep. Zinc content is 0.08% -1.00%, to increase the hardness of the alloy. Zinc is an excellent durable metal material which has natural corrosion resistance. It can form a dense passivated protective layer on the surface, so that zinc can maintain a very slow corrosion rate. Experimental testing and tracking showed that zinc corrosion rate of less than 1 micron / year, 0.7 mm Aluzinc Sheet can be used for nearly 100 years. Trauma can be automatically restored and the wound could be recovery of 0.001μ surface within one day, the thickness can be increased to 0.005μ after 1 day, 20 days later rose to 0.01μ. All self-protection metal can keep the metal gloss for a long time.
The Aluzinc steel sheet with thickness of 0.5 to 1.0 mm using for Roof and Wall, its weight is 3.5-7.5 kg / square meter. For example, 0.82 mm thick Aluzinc steel roofing panel weight is only 5.7 kg / square meter which is a very lightweight roofing material. The roof structure has no effect. The Aluminium-Zinc-plated steel sheet for roofing has a breaking strength of 16 kg / mm2, an elongation of 15-18%, an elastic modulus of 1.5X105 MPa and a density of 7.15.
