Steel Bar Grating Load Tables For Traffic Vietnam
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.
Load deflection tables are arranged in rising strength order. See the 4kPa, 5mm deflection column. U = Superimposed uniformly distributed load in kPa (100kg/m 2 = ) D = deflection in mm for the load U Assumptions for load capacity is on single spans. Based on allowable stress of 171 mPa for steel.
Laurel Custom Grating built its business and its reputation manufacturing heavy-duty steel bar grating, which remains its core product line. Laurel Custom Grating manufactures hand welded heavy-duty grating, which is by far the most efficient process, as it provides job-shop versatility without sacrificing economy.
W Series. Welded carbon heavy duty steel grating is the most popular choice where high strength is the primary grating requirement. The main bars are slotted and assembled with cross bars which are welded with one fillet weld at every joint. Stainless steel can also be provided for those high corrosive applications.
Note: Although the special 2” (50mm) cross rod spacing does allow for less open space on the grating surface, it does not affect the load rating of the grating. The most economical and readily available choice for bar grating selection is Type 19-4 (Type 30-102 Metric). *All weights will increase by 5% when galvanized.
Grating height = height of load bearing bars Panels can be laid out with matching cross bars. Valid for panels with the same length of load bars Flat bar welded to the ends of the load bearing bars connecting them together Has the same function as the binding bar, but usually only 15 mm high. Distance between load bars and cross bars (centre to
Webforge A & B patterns conform to the AS 1657 Code for Fixed Platforms, Walkways, Stairway and Ladders. These patterns are the most commonly specified and installed. This type of grating with its 30mm load bar centres has the greatest resistance to surface impact.

Tru-Weld Heavy Duty Steel Bar Grating is commonly used for floor trenches and sump covers exposed to heavy equipment traffic. It is used extensively through out mining, power generation, highways, airfields, and on truck terminal loading docks and ramps. It is suitable for large single span conditions or where grating must be support extreme loads.
Carbon Steel Bar Grating. Carbon Steel Bar Grating is an ideal option when your project requires a strong material that will not be exposed to an expressly corrosive environment. Direct Metals supplies both smooth and serrated bar grating. Bar gating is available in galvanized, painted black, plain steel, light duty, and heavy duty.
Banding. Heavy duty gratings are commonly subjected to shock and impact loads and it is highly recommended that all open ends be banded. The welded band bar helps distribute impact loads and minimizes distortion when subjected to repetitive traffic patterns.
HEAVY DUTY CARBON STEEL BAR GRATING . Heavy Duty Welded Steel Grating - W Series: Heavy Duty Welded Steel bar grating is a great selection when strength is required in architectural and industrial applications. This type of steel grating is produced when carbon steel or stainless steel bearing bars are welded to cross rods at each connecting point.
Select type of grating •"W" for Welded Steel Grating •"DT" for Dovetail Pressure Locked Grating •"SL" for Swage Locked Grating Select bar spacing from table above; Select bar size (consult load tables considering service loads and clear spans)
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.
