Dimond Purlin Systems require a minimum degree of maintenance in order that the expected performance is achieved by ensuring the galvanised surface is free from dirt buildup. Careful maintenance can extend the useful life of the Dimond Purlin System.
As a guide the following should be carried out as often as is needed (this could be as often as every three months).
- Keep surfaces clean and free from continuous contact with moisture, dust and other debris. This includes areas such as exposed undersides of canopies.
- Regular maintenance should include a washdown programme to remove all the accumulated dirt or salt buildup on all the galvanised surfaces with a soft brush and plenty of clean water or by water blasting at 15 MPa (2000 psi).
- Periodically inspect and replace where necessary any bolts or fasteners that have deteriorated to the extent that red rust has become obvious over most of their surface.
- Periodically inspect the Purlin, Girt, Fastbrace Brace Channel, Sag Rod members and all connections for signs of surface corrosion. Remove any surface corrosion and spot prime corroded areas that exhibit exposed steel substrate, and repaint to an appropriate paint manufacturer’s recommendations.
Any case of severe damage or corrosion must be reported to the design engineer.
