IMPORTANCE OF CORROSION PROTECTION
| Corrosion Issues and Fasteners |
| • |
Fasteners are a relatively small part of the costs of the roof construction, typically ~2%. |
| • |
While they are relatively inexpensive, selection of the incorrect fastener can cause a whole roof structure to fail. |
| • |
Occasionally the design performance of the fastener is a problem, but failures are usually related to the insidious effects of corrosion |
| Causes of Corrosion |
| • |
Salt laden air from the ocean. |
| • |
Airborne pollution and acids from industry and chemical sprays. |
| • |
Moisture or humidity in tropical and moist areas. |
| • |
The build up of moisture retaining dirt and contamination. |
