As we all know, only careful maintenance of galvanized coil products can make these products last longer and better. You should know that in the daily maintenance of galvanized coil products, regul...

Through long-term theoretical analysis, there may be two reasons for the rust of galvanized sheet: one is that the quality of galvanizing is unqualified, such as leaks, bubbles, etc. Such as acid r...

Due to the protection of the zinc layer, the galvanized sheet has good rust resistance. Common sites of corrosion are notches, which are brown-red rust spots, or white rust if the coating is oxidiz...

GI coil is steel coils with a layer of zinc on the surface. Galvanizing is a commonly used cost-effective rust prevention method. About half of zinc production is used in this process. Stainless st...

After receiving the galvanized coil, we cannot use them all at once due to the huge quantity purchased at one time. The vast majority of cold-rolled sheets need to be stored in warehouses first. Wh...

Galvanized steel sheet is a composite material of steel and zinc. Galvanized products combine the advantages of both materials. Composite materials have the strength and ductility of steel, plus a ...

The storage of GI coil is also learned. If it is not stored properly, it will rust and become moldy during storage. Due to the humid air, galvanized strip steel is easy to form oxidation with the a...

1. Before the belt is threaded, the hole shape of each frame should be adjusted, and the size of each pass should be measured to ensure that the square hollow section steel enters each frame stably...

1. Soldering temperature The welding temperature of the square steel hollow section is mainly affected by the high-frequency eddy current thermal power, the high-frequency eddy current thermal p...

1. Spray abrasive In order to achieve the ideal rust removal effect, the abrasive should be selected according to the hardness of the square rectangular tube surface, the degree of original rust...
