Gryffin’s standard process is to powder coat over a galvanized finish, to provide a duplex system, where the galvanization provides corrosion protection should the powder coat surface be penetrated and the powder coat top coat provides aesthetic appeal and or additional weathering protection. Gryffin follows third party supplier galvanization and powder coating standards, and only uses Certified Powder Coat Applicators.
Standard powder coating is suitable for general non-corrosive environments, and greater than 1 km from the sea. No Warranty provided.
Harsh environment powder coat options with Warranty available on request. Conditions apply.
Standard powder coat details:
- Hot degrease and iron phosphate clean
- First clean water rinse
- Second clean water rinse
- Dry and degas material in dry off oven
- Powder coat to 70 +/- 10 microns
- Cure material in cure oven to powder manufacturers specification
- Pack all product with protective packaging for transport
- Complies to AS4506-2005.
Galvanized finish: Following installation of all fasteners, break off points should be treated with a generous coating of zinc rich cold galvanizing paint.
Powder coat finish: As above with the addition of a matching colour touch up paint.
Gryffin designs, engineers and manufactures to any requirement and specification required.
