GratingProducts
Our GratingProductsHave YourFlooringNeedsCovered2GRATINGOur grating consists of load-bearing bars in avariety of depths and thickness’s, with lateralrestraint provided by 6mm square twisted crossbars.These are then forge-welded to the upper edgesof the load-bearing bars, producing a productof one-piece construction with a high strengthto weight ratio, which in turn meets therequirements of Australian Standard AS1657.Serrated GratingHas a serrated edge bar for enhanced anti-slipproperties. Serrated load bars are not availablefor 20mm deep grating.Below are examples of applications wheregrating can be used: Power plants Petrochemical facilities Mining operations Industrial construction Ship building Paper mills transportation (highway and rails) Wastewater treatment plantsNote: For sloping walkways 10mm x 10mm squarebar can also be welded on the top of the gratingto meet requirements of AS1657. Metallurgical plantsHow to Specify Grating Profiles Communication facilitiesWhen ordering, use the code break up belowto detail your chosen grating profile: Commercial facilities and other commercial,industrial and infrastructure projects Flooring in corrosive locationsWe can supply grating in standard and fabricatedpanels or customised to project specifications,ready for immediate installation.Types of GratingOur grating is available in either a plain surfacefor standard applications or serrated, oftenutilised when higher slip resistance is required.Plain (Standard) GratingHas a plain edge load bar and twisted cross rods.Rapid PerforatingPart No: R 30 A 325 MPURRapid grating30 Load bar pitchACross bar pitchA 100mm orB 50mmMMild steelPPlainP Plain orS SerratedUUntreated325 Bar size32 x 5Need Help?With over 60 years of combined experience,our team are the experts when it comes to findingthe right product for you.3

Our fibreglass grating is a one mesh patternutilising a 38x38mm grid, with an open area of70%. The 6mm load-bearing bars mean that ourfibreglass grating is bi-directional, so no loadbar direction is required, making it a simple yetversatile flooring option.Fibreglass Step TreadsBenefits of Fibreglass: Strength vs weight – Fibreglass grating islight-weight yet still retains its ability to evenlydistribute applied loads to adjoining bars Non-sparking, non-magneticand non-conductiveOur fibreglass grating is available in either 25mmor 38mm thick and can also be supplied witha diamond cover or gritted top when greatertraction is required.
