3.3.2 Tolerances
| Aspect | Allowable tolerance |
| Thickness | The tolerance on the thickness of the material shall be + 5% of the thickness. |
| Section | The tolerance on the outer diameter of circular column or the circle circumscribing the octagonal section shall be + 1.0% of the diameter. |
| Straightness | The completed pole shall be straight and true to the eye in axis over the entire length, and shall not deviate from straightness by more than 10 mm in 6000 mm or proportionately according to the length of the pole. |
| Twisting | The angle of twist between two through holes an d/or accessories shall be within 1.5 degree per 3 metre member length. |
| Pole length | The appropriate section length shall be not more than + 25 mm and the overall length by more than + 12.5 mm. |
- Base plate
A detachable base plate shall be made from galvanised mil d steel and attached to the base of the pole. The minimum dimension of each plate are as follow with minimum thickness of 3 mm to prevent the pole from sinking:
| Pole height (m) | 7.5 | 9 | 11 |
| Base plate wi dth(mm) | 82.5 | 90 | 100 |
- Mounting
Sufficient depth of pole planting is required to resist overturning with a minimum safety factor of 2.5, taking into consideration local soil conditions and expected maximum loading. The minimum planting depth shall be in accordance to the following table:
| Pole height (m) | 7.5 | 9 | 11 |
| Plante d depth (m) | 1.35 | 1.5 | 1.7 |
We cover the top and bottom parts of the pole with a mat or straw bale in order to protect it from damage to the galvanized surface that may occur during transportation. Packaging can also be done according to clients’ requirements.
Process of Production
