Did you know?

  • Single pack primers and topcoats cannot prevent the corrosion of steel, particularly in areas anywhere near the coastline or in internal, high humidity areas such as indoor swimming pools. High performance protective coating systems, including zinc rich primers, are required in these situations. 
  • Preparation and painting of steelwork in shop not only results in a vastly superior finish that lasts much longer, but is also significantly cheaper than doing the work on site. 
  • Hot dip galvanising is only one way of achieving galvanic corrosion protection. A zinc-rich primer can offer superior galvanic corrosion protection, and can be readily topcoated. A hot dip galvanised surface will require degreasing and surface abrasion before topcoating. 
  • Steel is often delivered with what looks like a smooth, bluish coating. This blue layer is millscale, a type of ferrous oxide, and must be removed prior to painting, otherwise the millscale will cause the underlying steel to corrode. 
  • Sharp edges on steelwork must be ground off to a minimum of 2mm radius before applying any protective coating. Without removal, the coating will pull away from the sharp edge, resulting in inadequate protection at this point. The result is edge corrosion. 
  • There is almost as much steel in a concrete structure as there is in an equivalent-sized steel structure. Concrete needs steel reinforcement to give it flexural strength. 
  • The only thing that prevents the rusting of steel reinforcement in concrete is the high alkalinity of the concrete. If the concrete is protected against acids (carbon dioxide, acid rain, etc) by the use of protective coatings, then the steel reinforcement won't corrode.
