RHINO GRATING The Professional Choice
www.rhino-grating.com.au
A Unique Product Product range designed for the International Market Our manufacturing factory boasts an extensive product range with a simplified key range of options packaged specifically for the International Market. RHINO GRATING product groups: • Load bar centres: 30mm load bar centres for high foot traffic. 40mm load bar centres for low foot traffic.
Long-term cost savings
Better still, RHINO GRATING is unique!
Multi-purpose utility and diversity in application are some of the best attributes a product can offer, and the RHINO GRATING products certainly offer these. Grating has many uses – not only in industry as walkway flooring but also as screens, drain covers and stairways.
Similar to a steel ‘I Beam’ where the strength is in the flanges, the bar profile gives around 25% weight reduction while retaining strength. This design saves not only weight, but also material cost and galvanising 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.
Important Please note: we can supply 60mm centres but this size does not meet AS/NZ standards for elevated platforms.

Pitch of Bearing Bar
The centre distance between two cross bars adjacent to each other is called pitch of cross bar. Standard pitch is 100mm.
The centre distance between two bearing bars adjacent to each other is called pitch of bearing bar. Standard pitch is 30mm (Series 1), 40mm (Series 2).
Grating Types I Bar or Flat Bar Grating The bearing bar comes in the form of an I-Section. This type of grating is used where high strength is required and light weight is critical. Commonly used for platforms and walkways. RG 253

Please note: •Load bar sizes range from 20mm to 100mm depth •Load bars are available in both FLAT BAR and I BAR
Serrated Type I Bar Grating The bearing bar comes in the form of an I-Section with the top surface formed by a series of notches. In addition to its high strength and light weight, this type of grating also has non-slip characteristics. Serrations are rolled on to meet strict health and safety requirements and contain sharp edges. Hot rolled serrations helps stop lacerations if someone falls on the grating.

• The shaded area of the table indicates grating with deflection less than span/300mm. • If serrated bar grating is selected, use the factors S and D to calculate stress and deflection. • For uniformly distributed loads other than 300kg/m2 (3kPa) grating stress and deflection can be calculated using the factor shown in the following table

Expanded Metal Expanded metal is an economical and versatile material which can be used for enclosure, protection, support and decoration. In the expanding process, expanded metal is made from a solid single sheet metal which is slit and stretched longitudinally. There is no weld or join in it, therefore loads are evenly distributed over a wide area. The strands and knuckles form a uniform angle, which adds more strength and rigidity, even if one or more points are cut, the intersections of strand still can support the loads.
Expanded metal plates are not perfectly square. Maximum out of a square along edge is 5mm per 1000mm of length or 10mm on diagonals per square meter. Sheet must be resquared by shearing each side of the edge.
