Various types of steel gratings are placed on the ground.

Steel Bar Grating, also known as Welded Steel Bar Grate is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle Bar Grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements.A device by which grating is attached to its supports. Banding: A flat welded to a side or end of a grating panel, or along the line of a cutout, and extending neither above nor below the bearing bars. Bearing Bars: Load-carrying members extending in the direction of the grating span. Bearing Bar Centers: The distance center to center of the 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.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.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.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.

Heavy Duty Steel Grating -

Steel Bar Grating with bearing bars thicker than 3/16" is considered to be "Heavy Duty" and carries the designation prefix "Type HD". Available bar thicknesses are 1/4" () , 5/16" () and 3/8" () in either plain or serrated surface.

min bearing horizontal dimension = 1" for grating depth 2 1/4" or less, min bearing horizontal = 2" for grating depth greater than 2 1/4" grating thickness grating thickness trim 1/4" thick grating thickness vertical leg as reqd for grating thickness aluminum or steel grating banding bar 3/8"x6" anchors @ 1’-6" centers grating grating bearing 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.Bearing bar types. Steel grating is made up of bearing bar and cross bar as certain distance by welding or pressure bar have the types: flat type (also called plain type), serrated type, I bar type (I plain type and I serrated type).adjacent bearing bar) of the Bar Grating item. Product Spacing (. 19-W-4) refers to the industry specification for Bar Grating products. For example, the first number refers to the bearing bar spacing measured on center (19 = 19/16" or 1-3/16"), the letter refers to the construction type (W = welded), andTypes 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.

Swage Locked - Bar Grating | McNICHOLS

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.

Bar grating is designed to hold heavy loads with minimal weight. Bar gratings are made of bearing bars and cross bars. The bearing bar is the main load carrying bar which runs the same direction as span. The cross bars are connectors made from a strip or rolled bars which extent across or through the bearing bars. Cross bars are welded, forged or mechanically locked.locked and chemically bonded to the web of each bearing bar. This separates and affixes bearing bars firmly in position and distributes concentrated loads to adjacent bars. The resulting panel can be easily fabricated with standard carpenters’ tools with abrasive cutting edges. Ask for the detailed Grating Field Fabrication Guide for further McNICHOLS Pultruded Fiberglass Grating offers strength and high load capacity. Bearing bars come in I-Bar or T-Bar. Also in a variety of resin types, colors, heights, and grid patterns. Constructed with rectangular bearing bar panels. Stock or cut-to-size at all 19 locations.

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.Steel Bar Grating with bearing bars thicker than 3/16" is considered to be "Heavy Duty" and carries the designation prefix "Type HD".
