As part of our standard surface preparation process for steel products, we have a very high pressure dustless water blasting system that cleans away any contaminants (grease, oil, dirt etc) while etching the galvanising coating. Where required we can blast right back to raw steel to enable a primer coat to be applied - this is especially important where the finished product may be exposed to corrosive environments - e.g.beach or coastal locations. Powder top coats are not impermeable and may allow water to migrate through the coating over time.
Standard items such as pipe, gate frames etc are cleaned very quickly, larger frames and fabricated steel items will take longer (an additional time based charge for extended blasting will apply.)
