1 GRATINGThe Professional ChoiceA Unique ProductPitch of Bearing BarThe centre distance between two bearing barsadjacent to each other is called pitch of bearingbar. Standard pitch is 30mm (Series 1),40mm (Series 2).Product rangedesigned for the InternationalMarketOur manufacturing factoryboasts an extensive productrange with a simplified keyrange of options packagedspecifically for the International Grating product groups: Load bar centres:30mm load bar centres forhigh foot load bar centres forlow foot Please note: we cansupply 60mm centres but thissize does not meet AS/NZstandards for costsavingsMulti-purpose utility anddiversity in application aresome of the best attributes aproduct can offer, and theRHINO Grating productscertainly offer these. Gratinghas many uses not only inindustry as walkway flooringbut also as screens, draincovers and stairways. Better still, Rhino GRATINGis unique!

2 Similar to a steel I Beam where the strength is in theflanges, the bar profile givesaround 25% weight reductionwhile retaining design saves not onlyweight, but also material cost and galvanising cost. Savingsare also made in the design ofthe supporting structure forthe grate, as the product is somuch lighter and stress isreduced. Pitch of Cross BarThe centre distance between two cross barsadjacent to each other is called pitch of crossbar.

This type of Grating is used wherehigh strength is required and light weight iscritical. Commonly used for platforms note: Load bar sizes range from 20mm to 100mm depth Load bars are available in both FLAT BAR and IBARS errated Type I Bar GratingThe bearing bar comes in the form of anI-Section with the top surface formed by aseries of notches.

3 In addition to its highstrength and light weight, this type of gratingalso has non-slip characteristics. Serrations arerolled on to meet strict health and safetyrequirements and contain sharp edges.
