After galvanized steel grating produced, to be anti-rust treatment. There are hot-dip galvanized and electro-galvanized two kinds. Hot dip galvanized steel grating, also known as hot-dip galvanized steel grating: He is at a high temperature to melt the ingots in put some supplementary material, then dipped galvanizing bath metal structure that is attached to a metal member zinc coating layer. HDG has the advantage of his strong anti-corrosion stainless steel treads, zinc coating adhesion and hardness better. After the product has been galvanized to increase weight, we often say that the amount of zinc, it is mainly for hot-dip galvanizing for the. Cold-plated steel grating, also known as galvanized steel grating: that the zinc salt solution by electrolysis, iron and zinc ions were replaced to reflect, in general without heating, the amount of zinc rarely encountered moist environment is very easy to rust . Because of the different amounts of zinc so these two products will there is a big price difference. Steel grating treads are non-slip and side plus a combination of deep-processed products. Mainly used in steel staircase, also known as stair stepping, stepping ladders, ladders board, grille still, tap plates. Depending on customer requirements, treads are divided into direct welding or install two screws. Both treads difference: The first: direct welding of stepping, customer needs directly welded steel platform on the keel or inconvenience disassembly, easy to destroy the steel grating stepping zinc coating will surface. The second is welded steel mesh panels on both sides of 605 plates, perforated plates, direct screw-national platform pedals installed, easy to install treads, easy removal without damage to the surface of the zinc coating stepping. Common specifications and installation stepping classification board: T1 stepping: Installation: welded directly onto the keel or steel platform. T2 stepping: both sides with side panels, side panels on both sides with 605 flat punch, screw-national installation. T3 stepping: Installation: welded directly onto the keel or steel platform. Welding a checkered slip treads treads, played anti-collision, anti-card and other safety effects. T4 stepping: the front side with a checkered, with side panels on both sides, both sides of the flat steel plates with 605 drilling, screw-national installation.
