perforated aluminum sheet

There are many production links of blade barbed rope, and the finished product can only be produced after several times of production. Roughly, there are four or five links.

1. Pickling treatment: the steel wire is soaked in an acidic solution to remove the oil stains and oxidation layers on the surface to ensure the adhesion of the zinc layer.

In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
