steel bar grating load tables
Available bar thicknesses are 1/4" () , 5/16" () and 3/8" () 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.
In industrial applications, bar grating is the most widely used flooring for stairs, mezzanines and walkways. AMICO produces more variety and volume of these products than any other single manufacturer in the world.
DFW Grating 3835 Singleton Blvd. Dallas, TX 75212 214-630-0033 HEAVY DUTY STEEL BAR GRATING 15 Space Use this table when evaluating spans and loads for the following types of steel grating: Load Table 15-W-4 and 15-W-2
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)
Webforge Steel Grating Deflection Data Utilise the following table to select the appropriate grating profile for your application and project specifications. The current or proposed span should be reviewed in conjunctions with the load bar direction.
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.

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.
A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets. Steel bar grating is manufactured in a variety of methods. Welded bar grating consists of load bars electrically fuse welded to cross bars.
At McNICHOLS we carry a wide variety of Bar Grating. Our products include Welded, Swage-Locked, Press-Locked, and Clinched styles in many bar sizes, spacings and materials. Applications include walkways, platforms and trenches. Stock panels or fabrication at all 19 locations. Email us today.
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.
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
Shop 19W4/19W2 welded carbon steel bar grating at Brown-Campbell. 1-3/16in. Center to center of bearing bars. Commonly used where pedestrian and/or vehicular traffic is present, 19w4 and 19w2 bar grating is available in a large array of bar sizes, finishes, and surfaces.

Load bar are assumed simply supported and unserrated steel with Fy – 260 MPa. PLAIN – 30 X 100 mm Pitch. SERRATED – 30 X 100 mm Pitch LOAD TABLE DATA. Our grating clip is designed to secure the grating to the supporting steel structure. And can be done quickly and safely by a man using only a screwdriver, working from the floor
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.
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.
