heavy duty steel grating Feature:

Welded steel grating

when selecting a bar grating product, consider Welded Steel Grating first. Usually our most economical products, they provide a comfortable walking surface with nearly 80 percent open area. This, combined with the positive welded cross bar/bearing bar intersection, make these products our most popular. Manufactured from ASTM A-1011 carbon steel, welded gratings are recommended for nearly all industrial flooring applications.

Stainless Steel Grating

When considering grating for food processing applications,shipboard use, or highly corrosive environments, Stainless Steel Grating is often the most cost effective product.Commonly manufactured in 300 series alloys, stainless steel gratings are assembled by welding or pressure locking to suit the specific needs of each application.To specify Stainless Steel Grating, the type of grating is indicated by designating one of the three profiles shown combined with the bearing bar/cross bar spacing illustrated in the table below.

Stair Treads

Carbon steel, aluminum and stainless steel treads are manufactured with a variety of defined, visible nosings, and pre-punched end or carrier plates, ready for bolting to the stair stringers.
