Steel grating is an open plate steel member that is orthogonal combination of bearing flat steel and cross bar according to a specified distance, and is fixed by welding or press lock. According to different manufacturing methods, it is mainly divided into pressure welded steel grating and pressure lock steel grating. Widely used in petrochemical, electric power, tap water, sewage treatment, shipbuilding, self-propelled parking lots, municipal engineering, sanitation engineering and other fields of platforms, walkways, trestles, ditch covers, manhole covers, ladders, fences, etc.
The cross bar of steel grating is generally twisted square steel, round steel or flat steel, and the raw materials are divided into carbon steel and stainless steel.
Steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. Stainless steel can also be used. Steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
Treatment Method of Steel Grating Plate Stress Problem
When the diagonal deviation of the steel grating is large due to improper stress, it is recommended that two people erect the steel grating, and let one of the long diagonal corners of the steel grating gently repeatedly bump against the ground, and do not use too much force.
When the steel grating is bent and warped due to uneven force for a long time during transportation, the steel grating is placed on sleepers, bricks or other raised objects, and the warped surface is upward, so that the bent place is in contact with the raised object, and the two people stand on the two ends of the steel grating respectively, and slowly exert force;
When the edge plate of the steel grating is deformed due to bumping, it is recommended that we use a sledgehammer to hit or use a wrench to correct the deformation. Be careful not to use too much force.
