Introduction
Steel gratings are made by the load bearing bar and crossing bar (twisted square steel, square steel, round steel, flat steel, etc.) arranged in a certain distance between warp and weft.They are made to the original plate on the high-voltage resistance welding machine welding.After cutting, incision, hole opening, cover edge and other process, they become the products which meet customer’s requirements.

Steel grating type
According to the shape of the surface,they can be divided into tooth-shaped steel grating, flat steel grating, I-type steel grating and composite steel grating.
According to the surface treatment,they can be divided into hot-dip galvanized steel grating, spray paint steel grating and original steel grating.
Application
Steel grating is a kind of widely used grid products. They are used in various industrial fields and has the strongest resistance to surface impact. The platform steel grating is suitable for alloy, building materials, power station,boiler,ship building,petrochemical & chemical industry,factory, municipal construction and other industries. It is a new type of building product with ventilation and light transmission, anti-slip, strong bearing capacity, beautiful and durable, easy to clean and install. It can add welding kick plate (baffle plate), pattern plate protection, installation connection and other accessories from all sides. They can use with different specifications of bearing bar, or angle bar, channel steel and square pipe for edge covering. Handlebars and hinges can also be installed on steel grating that need to be moved or opened frequently.
