1. Common Steel Grating
The most economical choice of steel grating product. This grating is manufactured by an electro-forging process, welding rectangular bearing bars and cross rods. This welding method provides a positive fusion of cross rods and bearing bars. The most popular is the 19-4 spacing; with approximately 80% open area the 19-4 spacing allows for passage of dirt, snow, liquids, air and debris. Welded bar grating is also available in close mesh ADA conforming spacing for use in public areas. Different bearing bar thickness can be specified, the most common 3/16" is stocked in multiple depths. 1/8", 1/4" are stocked in limited quantities. Bearing bar thickness is offered from 1/8" to 1/2" to accommodate any load rating requirements. Universally used in most general industrial plants as well as commercial buildings; it has a wide range of uses such as walkways, platforms, safety barriers, ventilation grates, and drainage covers.
Heavy-Duty is typically 1/4" or thicker bearing bars. Depths range from 1" to 6", deeper bearing bars can be custom fabricated upon request. These heavy duty gratings are used mainly in parking lots, railroad yards, truck and bus terminals, industrial plants, highways, airfields, reinforced concrete areas, inlet covers, ventilation grilles, trenches. Heavy duty grating is available in a number of spacing options. When rolling wheel loads are to be used, we recommend the grating to be load banded to add lateral strength. Serrations are available on bearing bars up to 3/8" thick.
This grating is a system of interlocking, perpendicular bars, it provides a smooth clean look ideal for architectural applications such as grilles, divers and screens. It is used in the same structural applications as its welded steel counterpart. It is offered in a range of spacing options from 7/16" to 1-3/16". Press-Locked grating is not recommended for rolling loads. Instead of welding the joints, tremendous hydraulic pressure is used to bond the two close-tolerance slotted bars together. Permanent locking is achieved by forcing the deep cross bar into the notched bearing bar.
(4) Stair Treads
Welded Bar Grating is the most common for stair treads, and are widely used for their strength and ease of installation and are universally used in most industrial and commercial applications. All stair treads are custom fabricated to meet the size, width and length specifications of a particular job. In addition, standard end plates or custom fabricated end plates can be used to meet any bolt hole size or location requirements. Serrated bearing bars can also be used to offer additional slip resistance. Different types of nosing are available to add a definitive visible edge and slip resistance for extra safety.

1.Hot-dip galvanizing: Rust strong, maintenance-free and replacement.
2.Best drainage: water leakage area of 83.3%, is more than double the cast iron.
3.Save investment: long-span. Heavy load than cast iron and the lowest savings in the cost of replacing stolen, then crushed.
4.High strength: strength and toughness is much higher than cast iron, can be used for port, airport and other large span and heavy load conditions.
5.Size Multi: different specifications can meet the different environments, load. Span, size and shape required.
Packed in bundle then fixed by steel belt as the general export package and we also could pack it according to customers' requirement.
Hot to order steel bar grating ?
· It’s better that you can provide drawings with detailed information like raw material, grating type, surface treatment, quantities, etc.
· If you are not able to provide the drawing, we will design for free according to your specific applications.
· A free design will need information like: area of application (industrial platform, airport, docks, etc.), drawings of this area with detailed dimensions, boundary conditions, etc.
