perforated aluminum sheet

1. The surface of the stainless steel pet cage is deposited with dust or alien metal particles containing other metal elements. In the humid air, the condensed water between the attachment and stainless steel will connect the two into a micro cell, which causes the electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion. To avoid this situation, as long as the stainless steel surface is clean, you can ensure that the stainless steel pet cage does not rust.

The protective duration of the galvanized layer of large roll galvanized wire is closely related to the thickness of the coating. Generally speaking, in relatively dry main gas and indoor use, and in harsh environmental conditions, the thickness of galvanized layer needs to be very high. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance.

The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.
