webgrate: Versatile Grating Solutions for Enhanced Efficiency

Top-quality steel webgrate solutions, designed for durability and superior performance.

Ideal for demanding environments, MULTI STEEL’s webgrates are a reliable choice for any project requiring robust and efficient steel grating options.
In its standard form WEBGRATE is supplied with plain load bearing bars and 6mm square twisted cross rods.
Serrated grating is available with most standard load bearing bars. The serrations are formed by placing a series of notches along the upper edge of the load bar, thus enhancing the non-slip characteristics of the grating. When serrated grating is required it must be nominated (eg. WA325 Series 1 serrated). Use should be made of the serrated conversion factors, shown below the Load Tables, when determining load bearing and spanning capacity.
The figures shown in the Table of Loads and Deflections have been calculated in accordance with S.A.A. Steel Structures Code – AS3990 for steel having a minimum yield strength of 260 MPA as required by AS3679 Part 1.
Stock Sheets are manufactured in a standard nominal size 1.0 metre wide × 6.0 metres long.* Other widths and lengths are available on request. The most popular grating types can usually be supplied in standard sizes direct from stock. Our range also includes other combinations of grating. The delivery time of fabricated panels should be confirmed when an order is placed.

WEBGRATE is generally supplied in either of three standard finishes:

  •  UNTREATED – no rust protection, thus allowing quicker deliveries to clients who fabricate their own grating.
  • BLACK BITUMEN PAINT – a most economical paint finish where the grating is dipped in a tank of bitumen based paint. There is no pre-treatment of the steel before dipping. This coating is most suited for indoor and dry conditions.
  • GALVANIZED – this finish ensures that the entire surface area is protected by a uniform layer of zinc and therefore is suitable for the majority of applications. Hot dip galvanizing conforms to the following equivalent standards: AS1650, BS729, ASTM A123 and GB2518.


The minimum average coating required by these standards is 610gms/m2
