Pitch of Bearing Bar

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).

Please note: Load bar sizes range from 20mm to 100mm depth. Load bars are available in both Flat Bar and I Bar

Product range designed for the International MarketOur 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.

Important Please note: We can supply 60mm centres but this size does not meet AS/NZ standards for elevated platforms.

long-term cost savingsMulti-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.

Better still, RHINO GRATING is unique!

Pitch of Cross Bar

The centre distance between two cross bars adjacent to each other is called pitch of cross bar. Standard pitch is 100mm.

Construction of Platform Grating

UnIqUe I bar ProdUCt

I bar or GratingThe 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.

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 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.

serrated type I bar GratingThe 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.

InternatIonal standards GUaranteed

ManUfaCtUrInG toleranCes

When quality is the cornerstone of all operations, standards must follow international benchmarks.

Supplied throughout Australasia RHINO GRATING is made to international standards AS1657-1992 Fixed platforms, walkways, stairways and ladders 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.

Our 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 customers.

The standard applicable for galvanising is AS/NZS 4680 – Hot Dip Galvanized (zinc) coatings on fabricated ferrous articles.

This can be secured quickly and safely by one man, working from the floor surface. Available in Boxes of 50

Important note: A minimum of four clips per panel must be used to restrain floor panels. Where larger panels are to be fixed, it is advisable to use extra clips on any available intermediate supports.
