sale galvanized steel drain grate,floor gully grating manufacuture
Steel grating is flat steel bar according to a certain distance and cross arranged and
welded into the middle of a square lattice with an iron and steel products ,steel grating
generally use carbon steel production,appearance of hot dip galvanized,can serve to prevent
the role of oxidation,can also be made of stainless steel .
Product Detail
Surface Treatment
galvanized
painted(all colors)
Untreated(black self-color)
Productive Process
material:high quality carbon steel or stainless steel
Weaving: plain weave, twill weave, bamboo flower weaving, knitting contrast.
Welding process of gratings: Steel Grating Mesh is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and other processes.
Surface process of gratings: there are three types:hot-dipped galvanized ,electro-galvanizedand spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
Product Features
High strength, light structure, a strong bonding structure of the grid so that it has a high load, the structure of light, easy lifting; shape beautiful, durable, hot-dip zinc surface treatment so that it has a very good corrosion resistance, surface gloss appearance ; ventilation, lighting, cooling, explosion-proof, anti-skid performance is good; no plot dirt, rain and snow is not the plot, not water, self-cleaning, easy to maintain.
Product Advantage
Light weight, great load-bearing capacity, non-slip and safe, easy installation, material-economic, sturdy and durable, ventilated, easy to clean and attractive appearance.
