Physical and chemical properties of zinc
      Zinc metal, chemical symbol Zn. Is a chemical periodic table H vice ethnic elements are six basic metals. Zinc is a bluish white gray metallic, with a metallic luster, mostly in circles naturally sulphide state exists. Zinc density of 7.2 g / cc, a melting point of 419.5 ℃, boiling point 906 ℃, Mohs hardness of 2.5, a hexahedral crystal structure which is extremely stable and can not be changed, but can be strengthened. Fine crystalline zinc ratio of coarse crystals Kun zinc easy rolling and spinning.
      Zinc can not be dried at room temperature under air, carbon dioxide-free air or dry oxidation by oxygen. However, in contact with the humid air, the surface will be gradually oxidized layer of basic zinc carbonate dense white wrap its surface, to protect the internal longer be eroded.
     Shenzhen Shun Fat door new protective fences, security windows, garage doors and other profiles are used the most advanced anti-rust zinc alloy substrates (high intensity). The use of high-tech technology, the twenty special surface treatment, such as hot-dip zinc: play electrochemical protection, electric prevent the substrate within the channel outside the rust (no rust). Organic zinc epoxy powder coating: with excellent corrosion resistance and anti-impact performance. Polyester color powder coating: UV stability, long-term anti-dirty properties and surface self-cleaning properties. Optional multi-color performance (color many and cheap).
     Shun Fat doors security windows are made of zinc alloy without welding and becoming advanced technology (simple). Assemblies are made of high-strength nylon construction, its strength, hardness is much higher than ordinary steel. Per square centimeter can withstand 183mpb anti-extension strength, can withstand 221 ℃ high temperature deformation.
     The Company solemn promise, zinc alloy door profiles along its service life in harsh environments up to 30 years. 30 years, subject to a 3% surface rust (except human destruction) will be given a free replacement.
The manufacturer recommends guidance, spraying security window 170 yuan / square meter, grain imitation to 200 yuan / square meter.
