Zinc Plate Galvanized Steel Coil
(1) Surface state: galvanized coating process due to the different treatment,
surface state are also different, such as the common spangle, small spangle,
formation of zinc flower, no spangle and phosphating treated surface.
German standard is also provided with a surface level.
(2) Zinc Plate Galvanized Steel Coil should have a good appearance,
without use of harmful defects of products, such as no plating,
holes, rupture and scum, more than the thicker coating, scratches,
dirt chromate and white rust and so on.
Foreign standards for the specific appearance of the provisions are not very clear.
In order to some specific defects in the contract should be specified.
Galvanized steel coil, is a new type of construction material, is the surface of a layer of metal zinc plating, mainly to prevent corrosion.
On the surface of a layer of about 1 mm of metal zinc steel, with anti-corrosion effect, in the construction industry is widely used, this kind of zinc coated sheet steel. Zinc plating is a kind of economical and effective method which is often used. About half of the world's zinc production is used in this process.
