Composite cover Steel Grate for stair treads

The steel grate is generally made of carbon steel, and the surface is hot-dip galvanized, Galvanized Steel Grate,which can prevent oxidation. It can also be made of stainless steel. The steel grate has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.

Steel grate is a kind of steel product with a square grid in the middle that is cross-arranged with flat steel according to a certain spacing and cross bars, and welded by a pressure welding machine or manually to form a square grid in the middle. The steel grating is mainly used as a ditch cover , steel structure platform board, step board of steel ladder, etc. The cross bar is generally made of twisted square steel.

   Details of Heavy Duty Steel Grate   

Steel grating models can be divided into two types: standard and non-standard: for example G325/30/100, where 325 means that the load-bearing flat steel is 32*5mm, 30 means that the load-bearing flat steel spacing is 30mm, and 100 means twisted bars (horizontal bars) The spacing is 100mm.

Surface treatment is an important part of steel grating. Different surface treatment methods can improve the corrosion resistance and aesthetics of steel grating. At present, the common surface treatment methods include electro-galvanizing, hot-dip galvanizing, and painting. Among them, electro-galvanizing is a method of depositing zinc on the surface of steel grating, which can improve the corrosion resistance of steel grating; hot-dip galvanizing is a treatment method of immersing steel grating in zinc liquid, the effect is better.

   Application of steel grate   

Steel grate is suitable for alloys, building materials, power stations, and boilers. shipbuilding. Petrochemical, chemical, and general industrial plants, municipal construction, and other industries have the advantages of ventilation and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean, and easy to install. Steel grate has been widely used in various industries at home and abroad, mainly used as industrial platforms, ladder pedals, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional Parking lots, fences of institutions, schools, factories, enterprises, sports grounds, garden villas, can also be used as external windows of houses, balcony guardrails, guardrails of highways and railways, etc.
