Product Specification

Painted Black Carbon Steel Flooring ASTM A1011 Standard Welded Steel Grating

Welded Steel Grating Introduction:

Heavy-duty welded steel grating is manufactured by fusing bearing bars and cross bars together at high temperatures to form a permanent joint. This type of grating utilizes deeper and thicker bearing bars to provide greater durability, strength and rigidity than light-duty grating options. Available material types include economical carbon steel and corrosion-resistant stainless steel.

As one of the top welded bar grating suppliers, Qijie Company can provide the right product for your company’s needs. Our standard carbon steel panels are available in mill finish, hot dip galvanized or powder coat painted finish, while our stainless steel panels feature a mill finish.

Our standard welded bar grating panels measure 2′-0″ or 3’0″ wide by 20′-0″ or 24′-0″ to meet most industrial and commercial requirements. We also stock virtually every type of stair tread, along with checkered plate and cast aluminum abrasive nosings.

Designed to carry heavy rolling loads and maintain the same level of performance over many years of use, heavy-duty welded steel grating is ideal for a variety of applications. Common uses include airfield landing mats, highway bridge decking, ventilation grills, curb inlet grates, ramps, docks, sidewalks, concrete reinforcements, vault covers, industrial flooring, trenches, marine platforms and paper mills.

Create safe and economical passage for heavyweight loads with high-strength heavy-duty welded steel grating from Qijie Gratings.

Stainless Steel Grating

Stainless steel bar grating is a choice for corrosive environments such as chemical, food and hydro processing areas. It is available in welded and press locked as well as in many bearing bar sizes.

Materials: The most common material is Type 304 (SUS304), however, Type 316 (SUS316) or Type 316L (SUS316L) is also available. 304 stainless steel is the most popular type contains both chromium and nickel to provide excellent balance resistance and workability. 316 stainless steel is better corrosion, pitting resistance and higher strength at elevated temperatures than 304. 316L is extra low carbon variation of 316 to avoid carbide precipitation due to welding.

Aluminum Grating

aluminum grating is designed to be a high-strength, low-weight product that uses an I-bar or rectangular bearing bar with cross rods hydraulically swaged under high pressure. Thus, giving you a rigid, virtually maintenance-free flooring product.

Similar to steel grating, aluminum grating can be pressure locked as an alternative to swage locked. This application process also allows the customer to choose a close mesh grate where certain special needs are to be met.

Open Mesh Grating

The open mesh steel grating is a flat panel with a light structure firmly welded together. It is widely used for industrial ladders, decking safety, ventilation ceilings and floors, platform and stair tread protection panels. The open spacing design instead of solid metals allows good ventilation, and easy flow of lighting and heat. The standard sheet size is 1m x 6m standard type (special size and American standard size are also customizable).
