Painted steel grating

Steel grating.After the production of galvanized toothed grille plates is delivered to the buyer's application, standard installation and fixing must be carried out. The main points of grid plate installation are fixed by electric welding and anchor bolt. The actual operation of secondary welding and welding fixed galvanized grid plate will certainly cause damage to the hot dip galvanized layer of grid plate. At the present stage, hot dip galvanizing is a wide range of anti-corrosion and anti-rust treatment methods in the field of grid plate. Because the zinc layer can produce a sealing protective layer on the surface of grid plate, it also has excellent practical effect of cathodic protection for pipeline. The cathodic protection of the zinc coating itself can also preserve the gas etched iron flat steel if the zinc coating is accidentally scratched.
