Thermal spray applications for the prevention of corrosion of balconies, fences, railings and architectural steel fabrications
Metal or thermal spraying for corrosion protection of steel is widely used in a large number of applications. One such range of applications is applying coatings to prevent corrosion of balconies, fences, railings and general architectural steel fabrications.
Commonly, thermal spray zinc (TSZ) coatings are applied either by the flame spray or twin wire arc spray process but depending on the environmental conditions and application requirements, zinc/aluminium (TSZA) or aluminium (TSA) coatings are applied.
Often, these items would be galvanised but thermal spray is an excellent alternative to the hot-dip-galvanise process. There is little to no heat distortion with thermal spray making it ideal for thin, lightweight structures which would normally distort in a hot-dip galvanising bath. The size of the objects to be sprayed is limitless allowing large balconies and fabrications to be coated without restriction of the size of the galvanising bath. The metal sprayed coating also gives an excellent base for subsequent paint or powder coating for aesthetic appearance.
The spray applied coatings offer sacrificial (zinc), barrier (aluminium) or a combination of protection in the case of zinc/aluminium alloy. Depending on the coating thickness and environment, independent standards (EN ISO 2063) suggests that coating life to first maintenance can exceed 20 years of protection.
The applications are wide ranging from domestic railings to playground equipment through to industrial equipment railing or sports facility barriers. The case studies and applications below give a small insight into the possibilities which also include some decorative coatings of copper and bronze.
