bearing bar grating
Bar grating is ideal for industrial steel grating flooring and metal grates. Direct Metals offers plain or serrated bar grating surfaces in galvanized, bare steel, or painted finishes. Welded bar grating is the most common type of bar grating. Welded steel grating is joined at the intersection of the bearing bars and cross bars.
Bar Grating load tables enable the user to select the appropriate bearing bar size for the actual uniform and/or concentrated load carrying capacity and a corresponding deflection for each size/type of bar grating at a given unsupported span. Additional details regarding Load Table Terminology & Formulas available.
Grating must be installed with cross rods on top side to achieve strength specifications provided. Metal should be used for all grating supports. A minimum of 1” bearing shall be provided for bearing bar depths up to 2-1/4”; 2” minimum bearing shall be provided for bearing bar depths of 2-1/2” or greater.
Type "SG" Swaged Rectangular Aluminum Grating. The most widely used aluminum grating, type "SG" rectangular bar provides clean, crisp lines and the cross bar is fully locked within the bearing bar, slightly below the top surface. Type 19-SG-4 aluminum grating is the industry recognized standard for industrial applications with nearly 80% open area.
Bridge Grating Solutions Components & Systems OHIO GRATINGS, INC. Vehicular Bridges Heavy Duty Riveted Grating Riveted grating was first developed and used in subways in New York City in the early 1900’s. Over the years this product has been Bearing Bar 1” x 1/4” Transverse
Types of Bearing Bar: Steel grating is perfect for factories, buildings. generating plants; in fact anywhere the ease of movement and safety is required. With steel grating quick fitting accessories, ease of cleaning, safety and strength will provide you with the economical answers to lots of applications.
Constructed from reinforced fiberglass plastic (RFP) composite, RFP grating is used in hundreds of commercial, industrial and residential applications, including platforms, handrails, decks, foot bridges, catwalks, pond skimmers and more. Look for pultruded, moltruded and molded grating in the most popular sizes and configurations.
TiteWeld™ Steel Bar Grating is ideal for very tight spacing requirements and maximum “roll-a-bility” requirements. TiteWeld™ bar grating satisfies ADA comfort requirements for wheel chairs and walking pedestrians. TiteWeld™ steel bar grating is Direct Metals' answer to applications requiring bearing bars placed close together.
Welded Grating. Economical design ideal for most industrial applications. Manufactured by welding the bearing bar/cross bar intersection, typically with automated forge welding equipment. Available in carbon steel and stainless steel. Swage Locked Grating. Popular for the manufacture of aluminum, stainless steel and close mesh gratings.
Riveted Grating is the first choice when greater rolling loads are required. Reticulated bars are riveted to bearing bars permitting a higher resistance to buckling caused by vehicular rolling traffic. Compared to welded bar or swage-locked grating, riveted has greater load carrying capacity for the same span and depth of grating.

Grating length = length of load bearing bar incl. binding bar. The span is the distance between two supports. The grating should be laid over two or more supports to reduce deflection. When stating dimensions the length of the load bearing bar is indicated by the first figure, . 810x 1000 mm.
Bridge Decking Bridge Decking is manufactured by cold-press riveting truss shaped reticuline bars to parallel rectangular bearing bars. The resulting product is an exceptionally durable heavy duty grating with superior stiffness and lateral stability.

Lightweight and corrosion resistant, aluminum grating is a cost-effective alternative to other grating products. Because it can be easily cleaned and does not absorb bacteria sustaining particles it can be used for sewage and waste treatment plants, chemical process industry, off-shore rigging drills, marine applications and more.
Pultruded Grating consists of a series of parallel bearing bars. The bearing bars typically have a ‘T’ or ‘I’ shaped profile. The closer the bearing bars are together, the stronger the grating. Cross-rods are not intended to be applied in the span direction. Pultruded grating can only support weight in the direction of the bearing bars.
Welded steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Welded bar grating is resistance welded to create a rugged, one-piece constructed panel. Standard panels are 2′, 3′ or 4′ wide by 20′ or 24′ long.
A series of bearing bars are welded, swaged and locked, or pressure-locked with perpendicular crossbars to form Grating panels. Bar Grating is a rugged, high-performance, low-maintenance, and slip-resistant product capable of handling pedestrian and vehicular loads.
