Forgebar Grating //
Forgebar grating is constructed of load-bearing bars in various depths and thicknesses. Lateral restraint is provided by 6mm square twisted cross bars, which are forge-welded to the upper edges of the load-bearing bars. This manufacturing process produces a product that offers one-piece construction and a high strength-to-weight ratio – one that meets the requirements of Australian Standard 1657 1992 and British Standard 4592 1970.
Material
The load-bearing bars in Forgebar gratings are manufactured from steel that complies to the following equivalent standards:
AS 1594-H250
AS 3679-250

Cross Bar Pitch
A = 100mm Centres
B = 50mm Centres
Load Bar Pitch
Series 30 - 30mm Centres
Series 40 - 40mm Centres
Series 60 - 60mm Centres
Load Bar Size
From 20 x 3mm to 65 x 5mm
Plain
FORGEBAR grating supplied with plain Load Bearing Bars and 6mm square twisted Cross Bars.
Serrated
FORGEBAR grating with a regular sharp-edged serration, which provides increased traction under slippery conditions. The reduction in load carrying capacity of serrated grating is minimal ( less than 8% on average)

Finishes
Forgebar grating is available either hot-dipped galvanised or untreated
1. Hot Dipped Galvanised
Hot dip galvanising produces a durable, abrasion-resistant coating of metallic zinc and zinc-iron alloy layers that are metallurgically bonded to the steel base at a bath temperature of 450C. Hot dip galvanising conforms to the equivalent following standards:
2. Untreated (No surface treatment or protection)
Untreated product can be supplied on stock mats or panels to customers who wish to perform their own fabrication on the grating.
