Hardware cloth offered by Huahai has two types of processing basically: welded or woven. They can be further classified into galvanized before or after. Photo illustrations listed below for further reference.
Processing types:
pre galvanized before welded;
hot dipped galvanizd after welded;
pre galvanized then woven and galvanized after woven.
Pre-galvanized wire mesh is the most economical but is more prone to corrosion because the galvanized surface is burned off where the wires are welded.
However, pre-galvanized is more attractive in appearance than hot-dip galvanized. Galvanization process coats the wire with a zinc layer. Zinc coatings prevent corrosion of the protected metal by forming a physical barrier and by acting as a sacrificial anode if this barrier is damaged. |
