What Is Steel Grating?

Steel grating is also called steel grating. The grating is a kind of steel product that is cross-arranged with flat steel according to a certain spacing and crossbars and welded into a square grid in the middle. It is mainly used as a drain cover, steel structure platform plate, steel ladder tread plate, etc., and the crossbar generally adopts twisted square steel.

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

Classification:

1. According to the welding method, can be divided into pressure welding type, embedded type, through-lock type, and through-welding type.

2 According to the shape of the side surface of the loaded flat steel, it can be divided into plane type, tooth type, and "I" type, etc.

3. According to its users, it can be divided into general-purpose steel grating and special-purpose steel grating, such as trench covers, step plates, and so on.

4. According to the material, the steel grating is divided into stainless steel grating and carbon steel grating.

Production Method:

1. The pressure-welded steel grating is made of load flat steel and horizontal bars arranged at a certain distance, welded into the original plate by 200 tons of hydraulic resistance welding automation equipment, and processed by cutting, opening, wrapping, and other processes according to customer requirements The product.

2. Loaded flat steel spacing: the center distance between two adjacent loaded flat steels, usually 30MM and 40MM.

3. Spacing between crossbars: The distance between the centers of two adjacent crossbars is usually 50MM, 100, or two types, which can be produced according to customer requirements.

4. Various types of steel gratings can be customized according to customer requirements.

Surface treatment:

Hot-dip galvanizing, cold-dip galvanizing, electro-galvanizing, painting, dipping in anti-rust oil, dipping in plastic, no treatment.

application:

Widely used in platforms, walkways, trestles, ditch covers, well covers, ladders, fences, factories, etc. construction, etc.

The steel grille fence is used as a substitute for the steel grille. The guardrail is also known as the fence net and the isolation fence, so the "steel grille substitute" is also called the steel grille. Because of its strong performance compared with the fence net, the use of steel gratings as grids is mostly customized for specific requirements, and is generally rarely used! The price is also 2 to 4 times higher than ordinary guardrails.
