GATIC®’s complete range of metal Access Covers, Road Grates and Frames are designed and tested in accordance with the Australian Standard AS3996 and the European standard EN124:1994. The following table provides an overview of loading classes, its typical use and loading capacity. Appropriate class for a cover or grate depends upon the place of installation.
Australian Standard - AS3996
The Australian Standard, AS3996 is GATIC®’s nominated standard for projects/applications within Australia. Type testing under AS3996 requires the Access Covers to meet the Ultimate Limit State Design Load (kN) without exceeding the Permanent Set and Deflection Limits. Refer to AS3996 subclause 4.2.1. for further details.
| CLASS RATING | TYPICAL USE | NOMINAL WHEEL LOAD (kg) | SERVICEABILITY DESIGN LOAD (kN) | ULTIMATE LIMIT STATE DESIGN LOAD (kN) |
|---|---|---|---|---|
| A | Footways and areas accessible only to pedestrians and pedal cyclists | 330 | 6.7 | 10 |
| B | Footways that may be mounted by a vehicle or livestock, and light tractor paths or residential carparks | 2670 | 53 | 80 |
| C | Minor roads ‐ Malls and pedestrian areas open to slow moving commercial vehicles | 5000 | 100 | 150 |
| D | Carriageways of roads and areas open to commercial vehicles | 8000 | 140 | 210 |
| E | Freeway and motorway carriageways, General docks and aircraft pavements | 13700 | 267 | 400 |
| F | Docks and aircraft pavements subjects to high wheel loads | 20000 | 400 | 600 |
| G | Docks and aircraft pavements subject to very high wheel loads | 30000 | 600 | 900 |
NOTE: The above descriptions of classes of units reference to “wheel” should also be taken to include “dual wheels”. Norminal wheel loads are a guide only. Consideration should be be given to the type, size and pneumatic pressure of the load in application. A force of 1 kN is approximately equal to the weight of 100 kg.
EN124 : 1994 - European Standard Load Classification
The European Standard, EN124:1994 is GATIC®’s nominated standard for International projects/applications outside of Australia. Type testing under EN124:1994 requires the Access Covers to meet the Minimum Design Load (kN) without exceeding the Permissible Permanent Set values. Refer to EN124:1994 subclause 8.3. for further details.
| CLASS RATING | TYPICAL USE | NOMINAL WHEEL LOAD (kg) | SERVICIBILITY DESIGN LOAD (kN) | ULTIMATE LIMIT STATE DESIGN LOAD (kN) |
|---|---|---|---|---|
| A | Footways and areas accessible only to pedestrians and pedal cyclists. | 330 | 10 | 15 |
| B | Footways that may be mounted by a vehicle or livestock, and light tractor paths or residential carparks | 2670 | 83 | 125 |
| C | Minor roads ‐ Malls and pedestrian areas open to slow moving commercial vehicles | 5000 | 167 | 250 |
| D | Carriageways of roads and areas open to commercial vehicles | 8000 | 267 | 400 |
| E | Freeway and motorway carriageways, General docks and aircraft pavements | 20000 | 400 | 600 |
| F | Docks and aircraft pavements subject to high wheel loads | 30000 | 600 | 900 |
