A36 Steel Welded Steel Grating 25×5 Steel Open Mesh Flooring

highways A36 Steel ASTM A123 Standard Smooth Surface Welded Steel Grating

Welded Steel Grating Introduction:

Bar grating in Light or Heavy Duty welded steel grating:

Light Duty steel grating ranges in size from 3/4" x 3/16" to 2-1/2" x 3/16"
Heavy Duty steel grating ranges in size from 1" x 1/4" to 6" x 1/2"

Light Duty Steel Grating Press Lock - DT Series:

Produced like aluminum press lock because it is made up of interlocking perpendicular bars
Hydraulic pressure (not welding) is used to bond the slotted bars together, locking the deep cross bar into the notched bearing bar
Has a smooth, clean look due to a flush top rectangular cross bar
Slip resistant surfaces for floor grating available upon request

*Not for rolling loads

Light Duty Steel Press Lock bar grating offers strong lateral stability. This steel grating is used in architectural design because of its clean look and tight spacing. The 1/4" and 1/2" openings of the steel grating conform to the “American with Disabilities Act” (July 1991).

Light Duty Riveted Steel Grating - R Series:

Rugged, reliable, and durable bar grating
Made by joining straight bearing bars and bent connecting bars with rivets
Connecting bars increase lateral stability and load capability
Ideal steel grating choice for when strength and rigidity is needed
Slip resistant surfaces available upon request

Heavy Duty Welded Steel Grating - W Series:

Heavy Duty Welded Steel bar grating is a great selection when strength is required in architectural and industrial applications. This type of steel grating is produced when carbon steel or stainless steel bearing bars are welded to cross rods at each connecting point. Heavy Duty Welded Steel grating can meet vehicle-loading requirements of AASHTO and is made to handle heavy rolling loads.

Heavy Duty Riveted Steel Grating - R Series:

Perfect for vehicle bridge decks and bridges, Heavy Duty Riveted Steel grating is an excellent choice when a great deal of strength and rigidity is needed. Steel grating is available as a slip resistant surface upon request.

Rugged, reliable, and durable bar grating
Made by joining straight bearing bars and bent connecting bars with rivets
Connecting bars increase lateral stability and load carrying capability

Welded Steel Grating Applications:

Uses: Stainless steel bar grating is mainly used in chemical industry, food processing, hydro processing and other industries as listed:

Power plant;

Chemical plant;

Oil Refinery;

Steel plant;

Machinery plant;

Paper-making factory;

Cement plant;

Civil engineering;

Wastewater treatment;

Pharmacy industry;

Food processing.

Welded Steel Grating Feature:

The products enjoy the features of high strength, light structure, high bearing, convenience for loading and other properties.

The excellent self-cleaning characteristics of plain surface grating make it suitable for the majority of applications. In the presence of fluids or materials that could cause the top surface of the grating to become wet or slippery, specification of the optional serrated surface should be considered. When serrated grating is specified, the bearing bar depth must be 1/4″ greater than the sizes shown on the load tables to provide the equivalent strength of non-serrated gratings.
