When the length of the steel grating is less than 1 m or there is end edge for the steel grating, the weight would increase. When we wrap with the bearing bar and the length of the steel grating is more than 1 m, we use the followingputational formula to calculate the theoretical weight. W t = (b 1 t 1 N1 + b 2 t 2 N 2 + 2b 3 t 3 )ρμ × /For serrated grating, the depth of grating required for a specied load is 1/4” greater than in the chart. U= Uniform load, Psf C= Concentrated load at (mid-span), LB per foot of grating width In order to obtain the permissible loading capacity for each type of grating, multiply its assigned value times the value on the table. 22W4 Y 22W2 0.85
This chart indicates the dimensions of each grating type to the nearest load bar for series 1,2 3 grating and the nearest full square for FRP grating. Please note spacings for series 1,2 3 are for 5mm thick load bars. How the heck is the weights calculated for grating? For example: I'm using a 15-DT-4 with 1 1/2 x 3/16 bars. Per the product load tables, it weighs 13.82 pounds per sq. foot. The Self-weight/m2 I need to use to make it properly show the square foot weight is 0.096. Later if I modify the properties of a peice of grate, this shows up as 1/8. GRATING: TECHNICAL DATA. GRATINGS: TECHNICAL SPECS. PRODUCT: self load bearing profiled metal plankings for walking surfaces. MATERIAL: 2 mm. thick pre-galvanized (sendzimir) steel. LENGTH: cut to size, maximum length mt. 10 (32.80 ft). WEIGHT PER SQUARE METRE: Flat and Ribbed types approx. 24 Kg. (52.91 lb); I shape bearing bars supplies lighter weight when the strength is equal to rectangular bar steel grating. I bar steel grating is suitable for bothmercial and industrial applications. Special I shape bearing bars. Lighter weight and high strength.

IMPERIAL TABLE OF SAFE LOADS. U – Safe Uniform Load, in lbs. per sq.ft. C – Safe Concentrated Load in lbs. per foot of grating width. Standard steel gratingprises plain square edge flat bars. In order to increase slip resistance there are a number of options available for consideration, especially for sloping walkways. As mandated by AS/NZS 1657, the use of 10 x 10mm square bar cleats is required for additional security under foot on walkways with a slope 100. ISO 14122.

Design consideration of the aluminum grating allows for the same load carrying capacity at less grating weight per square foot than rectangular bar, which results in cost savings .

SGS Approval Steel Grating Clips 316L Welded Type 100mm / 50mm M Span. 30 X 3 M Galvanised Grating Welded bar grating is the mostmon type of bar grating. Welded steel grating is joined at the intersection of the bearing bars and cross bars. Welded bar grating is a versatile option for light to moderate loads. When heavy loads are present, the Heavy Duty metal grating is the best option. The Heavy Duty steel grating can be appropriate for highways, airport runways, bridge floors and t1: Distance between the center to center of the bearing bar. q1: Distance between the center to center of crossing bar.
