Thermal spraying is mostly used to produce coatings on structural materials and also popular in the marine environment. Such coatings provide protection against high temperatures, corrosion, erosion, wear. Metal spraying is a good alternative to galvanising.
Long life spec - We are approved applicators for Akzo Nobel, who have tested our applications which allows us to offer a 20 year life expectancy on mild steel in a C3 environment if requested.
Metal spraying offers the following advantages over galvanising
-
Low heat input during spraying eliminates the risk of thermal distortion
-
Low heat input eliminates the risk of thermal metallurgical degradation
-
Sealed hollow fabrications may be treated without risk of explosion
-
The process is not limited to zinc. The coating material may be selected specifically for the environment
-
Coating thickness may be varied from place to place to provide extra protection in critical areas
-
There is no limit to the size of article which can be treated
-
Articles can be treated on site
-
There is no effluent disposal problem
-
Reduced stocks of zinc are required. Working capital is not tied up in a molten zinc bath
-
Fuel is not needed to keep zinc molten when the process is not working
-
Metal spraying is used to restore corrosion protection on damaged areas of welded galvanised steel.
