The manufacturing process of electro-galvanized steel coil is a process of forming a uniform, dense and well-bonded zinc coating on the surface of the steel coil by electrolysis. Compared to other metals, zinc is a relatively inexpensive and easily plated metal that is widely used to protect steel, especially against atmospheric corrosion. In recent years, …
The aluminum-magnesium-zinc steel sheet (Al-Ma-Zn) is a new type of high-corrosion-resistant coated steel sheet. Its base layer is mainly composed of zinc, plus 11% aluminum, 3% magnesium and a small amount of silicon. The surface of the aluminum-zinc-magnesium steel plate has a fine spangle crystal texture, and the surface is coated with a special resin …
Galvalume steel coil is a super material. Aluzinc is a coating material formed from a mixture of Aluminum (55%), Zinc (43.4%) and Silicon (1.6%). Durable and long-lasting, it provides superior performance and corrosion resistance under all environmental conditions. Shanghai Zhengshang Industrial Co., Ltd. produces high-quality 55% aluzinc steel coil. In addition to producing general specifications …
PPGI or PPGL (color-coated steel coil or prepainted steel coil) is a product made by applying one or several layers of organic coating on the surface of steel plate after chemical pretreatment such as degreasing and phosphating, and then baking and curing. Generally, hot-dip galvanized sheet or hot-dip aluminum Zinc plate and electro-galvanized plate are …
Galvanizing refers to the coating of metallic zinc on the surface of steel, and its function is to protect the steel from corrosion. Galvanized steel coil products are widely used in construction, machinery, industry, agriculture and other fields. It is one of the most widely used golden products in the world. Advantages Excellent anti-corrosion, paintability, …
Cold rolled steel coil/plate is hot rolled steel that has undergone further processing. The steel is further processed in a cold rolling mill, the material is cooled at room temperature, and then annealed or tempered. As a result, steel plates with smaller dimensional tolerances and smoother surfaces are produced. Watch on YouTube Shanghai Zhengshang Industrial …
Hot-rolled steel coils/plates are steels made by high-temperature heating and rolling. Its strength is not very high, but its plasticity and weldability are good. Hot rolling can improve the processing performance of metals and alloys, break the coarse grains in the as-cast state, heal cracks, reduce or eliminate casting defects, transform the as-cast structure into …
