Australian Standard AS3996:

The Australian standard sets out strength classifications and the loading conditions applying to these classifications. This provides a good guide for your project's requirements.

 

Class A - Test Load 10kN
Footways and areas accessible only to pedestrians and pedal cyclists (Extra-light Duty).

Class B - Test Load 80kN
Footways that may be mounted by a vehicle or livestock, and light tractor paths (Light Duty).

Class C - Test Load 150kN
Malls and pedestrian areas open to slow moving commercial vehicles (Medium Duty).

 

 

Other requirements of AS3996:

In addition to strength, AS3996 outlines requirements for gas and water tightness, keyhole dimensions, grate bicycle safety, identification markings, frame dimensions, etc. Talk to your Webforge sales representative about your project requirements.

Specifying drainage grate sizes

The industry convention is to identify the size of drainage grates by specifying the internal clear opening dimensions of the frame. For circular covers this dimension is measured as a diameter.

For square and rectangular covers, the normal convention is Width x Length (W x L).
