The galvanized flat steel is rolled with negative deviation, but it is delivered according to the actual weight, and the utilization rate is increased by 1-5 percentage points compared with the steel plate. The flat steel can be produced according to the user’s requirements with fixed thickness, width and length, which reduces the cutting for the user, saves the process, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and materials. The products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, lifting machinery and other industrial materials.
Material standard of galvanized flat steel: 1. Carbon structural steel GB700-88, high quality carbon structural steel GB / t699-1999, 3. Low alloy high strength structural steel GB / t1591-94.
Galvanized flat steel is coated with a layer of zinc on the surface of steel, which can play a very effective role in metal corrosion prevention. The manufacturing method of this kind of steel is not very complicated and relatively simple. Moreover, its galvanizing method also inherits the traditional hot-dip plating method. Up to now, the development scale of hot-dip galvanizing industry has become larger and larger.
Main uses of galvanized flat steel: galvanized flat steel can be used as finished material to make hoop iron, tools and mechanical parts, and used as house frame structural parts and escalators in buildings. The flat steel is rolled with negative deviation, but it is delivered according to the actual weight, and the utilization rate is 1-5% higher than that of the steel plate.
