Carbon Steel Bar Grating


serrated carbon steel bar gratingCarbon Steel bar grating is a nice choice when your project requires a strong material and you are not going to expose the grating to an expressly corrosive environment. Choose from plain or serrated bar grating surfaces, galvanized, standard black, bare steel or painted and Light or Heavy Duty Welded grating. Great for industrial steel flooring and metal grates.

Welded grating is joined at the intersection of the bearing bars and cross bars. Welded bar grating is a versatile option for light to moderate loads. When heavy duty loads are present, the Heavy Duty grating provides a nice option. This is appropriate for highways, airport runways and bridge floors.

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

GRATING TYPES - LIGHT DUTY WELDED STEEL W SERIES

This grating is best suited for industrial applications only and should not be specified where cosmetic appearance is important.

Light Duty Steel Press Lock - DT Series:
DT Series Light Duty Steel Press Lock is a bar grating produced in a similar way to Aluminum Press Lock in that it is made up of interlocking perpendicular bars. Hydraulic pressure is used to bond the slotted bars together, locking the deep cross bar into the notched bearing bar. This product has a smooth, clean look due to a flush top rectangular cross bar.

Light Duty Steel Press Lock bar grating offers strong lateral stability and is used in architectural design because of its clean look and tight spacing. The 1/4" & 1/2" openings conform to the "Americans with Disabilities Act" (July, 1991). Slip resistant surfaces are available upon request.

Light Duty Riveted Steel - R Series:
Light Duty Riveted Steel-R Series Light Duty Riveted Steel grating is a rugged, reliable and durable bar grating - evidenced by it being the oldest and longest-used style of industrial walkways. Riveted Steel grating is made by joining straight bearing bars and bent connecting bars with rivets. The connecting bars increase lateral stability and load carrying capability.

Light Duty Riveted Steel grating is an excellent choice when a great deal of strength and rigidity is needed. Slip resistant surfaces are available upon request.
