Galvanized steel grating steel grating produced after wholesale, 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 galvanized metal structure of steel grating groove much money, metal components attached to a layer of zinc layer. HDG has the advantage of his strong anti-corrosion, 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 is used as a stepping ladders on galvanized steel grating, it is usually referred to as stair treads. : Treads need to manufacture a variety of sizes to match the corresponding stairs, but from the point of view of the economy and security. Typically the width is not more than treads 305mm, the length of the treads is not more than 1000mm. : (1) treads welding requirements: the front fender and edging with each bearing bars by welding seam is not less than 3mm of fillet welds. (2) According to the treads welded into a fixed installation and bolted treads treads. Which is fixed by welding treads that general steel lattice panels, bolted steel grating treads need to add 65x5mm flat steel plate as a side. (3) According to the non-slip treads treads requirements can be divided into two kinds of the front fender (checkered or bars) treads and no front fender. For safety reasons, we recommend that customers use with front fender treads: for [(-3mm) -3mm].
