Storage & Handling
Like other building materials, purlins made from GALVASPAN® steel require care during storage and handling on site. Follow these recommendations:
- ideally, deliveries should be arranged so that the period between delivery and installation is minimised
- if the purlins aren’t required for immediate use, the bundles should be stacked clear of the ground and, if in the open, protected with waterproof covers
- if the bundles do become wet, the purlins should be separated, wiped dry and covered. (Any moisture that gets between bundled purlins cannot easily evaporate, and may cause unsightly coating damage that can reduce the life of the product), and
- bolts and nuts should be kept clean, dry and free of dirt or dust to prevent difficulties when tightening.
It's important to take care when lifting bundles of purlins. Long lengths should be lifted using a spreader bar and fabric slings. Take special care to prevent damage at the lifting points.
