Steel bar grating is the staple of the grating industry, mainly used for flooring applications. With a large list of options, any need can be met.

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.
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". Dove Tail 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.
Swaging is the least commonly used choice of connection for steel bar grating. This grating is similar
in construction to our aluminum bar grating products. Rectangular bearing bars and tubular cross
bars are joined together via the swaging process. This process keeps the material free from the
warping and weld flash inherent in the electro-forging process. This profile offers the same
flexibility as our other mechanically locked grating products as to multiple spacings (including
ADA requirements), bar depths and finishes
All forms of light duty and close mesh carbon steel grating are also available in stainless steel (both 304 &
316). Stainless steel is great in corrosive environments and environments that need to keep clean such as
food and chemical plants. Welded stainless steel grating can experience discoloration during the
welding of the crossbars to the bearing bars. Passivation and bead-blasting are available to make the
grating stand out and appear new for years to come. This process also removes the discoloration
caused by welding. Swaged and dove tail options are popular for stainless steel as discoloration
does not occur.
