Galvanized Expanded Metal Driveway Steel Grating Grates Grid For Bridge

product description:

Steel bar grating is manufactured from ASTM A-1011 mild carbon steel and is available in three distinct products: type "W" welded bar grating, type "DT" dovetail pressure locked grating, and type "SL" swage locked grating. All three products are available with bearing bar spacing ranging from 19/16" (1-3/16") to 7/16" on center and cross bars at either 4" or 2" on center.

Each product has a standard plain surface or may be specified with optional serrated or Algrip surfaces.

Finish options include bare steel, painted, hot dip galvanized, or specialty coatings. The steel bar grating load tables provide detailed specification information related to these products.

Fisholow aluminum gratings employ a unique interlocking system that joins the bearing and cross bars together in panels of exceptional rigidity and strength.

Lightweight, corrosion-resistant, non-sparking alloys are ideal for pedestrian platforms in chemical, petroleum, hydro and food processing plants, in sewage, water and waste water treatment facilities. Also available in close mesh and serrated.

U= Safe Uniform Load, in lbs per sq ft or kPa

C= Safe Concentrated Load in lbs per foot of grating width or kN per metre of grating width

D= Deflection in inches or mm

Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers, and airports. Since conditions can range from smaller forklift to large truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings

Design Criteria

Vehicular loads are designed in conformance with current AASHTO specifications for classifications H-15 through H-25. Automobile and forklift loads are similarly evaluated with loads calculated and distributed in accordance with the "Maximum Traffic Conditions" presented here.

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" (6.4mm) , 5/16" (7.9mm) and 3/8" (9.5mm) in either plain or serrated surface. Standard depths range from 1" (25mm) up to 4" (102mm), although larger sizes are available upon request.

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.

*All weights will increase by 5% when galvanized.

If your application is not adequately addressed by these load conditions, please contact our Engineering Department and we will gladly assist in the selection of an appropriate heavy duty grating for your specific need.

Materials & Spacings

Heavy duty gratings are manufactured in carbon steel and 300 series stainless steels. Carbon steel products are available bare (no finish), painted with manufacturers standard paint, or hot dip galvanized. Stainless steel products are available mill finish, commercially cleaned, or electro-polished. Below you will find a table of spacings for our most popular products.
