Product Catalogue - Perry Grating

1 Industrial floor Grating and handrail stanchions. The complete package of manufacture, galvanizing and delivery. For quotations or general enquiries, contact Perry Grating : Email CatalogueRefer to our terms and conditions of 0800 425 848 Unique ProductPitch of Bearing BarA centre distance between the two bearing bars adjacent to each other is called pitch of load bar. Standard pitch is 30mm (Series 1),40mm (Series 2). Product range designed for the Australasian marketOur manufacturing factory boasts an extensive Product range with a simplified key range of options packaged specifically for the New Zealand and Australian Grating Product groups: Load bar centres: 30mm load bar centres for high foot traffic. 40mm load bar centres for low foot please note: we can supply 60mm centres but this size does not meet AS/NZ standards for elevated cost savingsMulti-purpose and diversity are some of the best attributes a Product can offer, and the Perry Grating products certainly offer these.

2 Grating has many uses not only in industry as walkway flooring but also as screens, drain covers and stairways. Better still, Perry Grating is unique! Similar to a steel I Beam where the strength is in the flanges, the bar profile gives a 25% weight reduction while retaining design saves not only weight, but also material cost and galvanizing cost. Savings are also made in the design of the supporting structure for the grate, as the Product is so much lighter and stress is reduced.

Supplied throughout Australasia Perry Grating is made to international standards and the factory is accredited to ISO 9001:2000. The ISO 9001:2000 is an international quality management system involving external audits and stringent quality management criteria.

4 Incorporating fourteen grate forging machines, the factory has high manufacturing tolerances. This is shown in the unique vertical alignment of the load bars resulting in a stronger, better-looking Product for our standard applicable for galvanizing is AS/NZS 4680 Hot Dip Galvanized (zinc) coatings on fabricated ferrous SideS SideIGIn GroundSTANDARD BASE PLATETOP OF STEEL(BEFORE GRID)Standard Stanchions* BEFORE ORDERING: Check suitability of this dimension to match adjoining horizontal rail and adjust if note: ALL DIMENSIONS AROUND CENTRE LINES ALL DIMENSIONS IN mm ALL DIMENSIONS ShOwN CAN BE ALTERED TO SUIT ANy RE qUIREMENTS ALL STANChIONS AVAILABLE DRILLED ONE SIDE ONL y ( )1017560457 AMSCSide ConveyorSCSide ConveyorSOSide OffsetP UNIC orner Post5555457560505101775^ 110,115,135,145mm optionsMANUFACTURED TO AS1657-1992 Sydney Walkway SystemTYPE AM TYPE W HANDRAIL BENDS90 BENDSTYPE S TYPE SAR TYPE P SO FLANGESANGLE CLOSURE BENDP ohokura Oil Rail and Grating AccessoriesField Welding1.
