black sheetrock screws

Second, composition. Model 201 is composed of 17Cr-4.5Ni-6Mn-N, which is a substitute steel for type 301 steel. Anping wire rolling cage is magnetic after cold working, used in railway cars. 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat resistant steel. Used for food production equipment, Xitong chemical equipment, nuclear energy, etc.

First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.

The policy of wire mesh mesh size, wire, square meter steel content, galvanized amount, etc., to consider the corrosion resistance of wire mesh ability and system safety! Wire mesh galvanized is more fierce than wire diameter, galvanized amount is very important, must be hot plating, welding after plating is better than the first plating after welding, as for wire diameter, summed up to consider the site construction and meet the needs of safety.
