Rubb’s hot dip galvanized steel provides a consistent zinc finish on exposed and inside surfaces. Our buildings last longer because of this added protection.
We get numerous enquiries for replacing non-galvanized steel structures that have corroded, especially in higher corrosive environments. Be wary of other building providers where steel framework is galvanized before fabrication or painted. This is more susceptible to corrosion. It is important to make sure the protection is sufficient for the location. Rubb can enhance the galvanizing bond to suit marine or other corrosive environments.
Galvanizing is the process of metallurogically bonding a tough coating of zinc into the steel surface. Microscopic analysis shows that there is no demarcation line between the steel and zinc but a gradual transition through a series of zinc-iron alloys. The protective coating is fused into the metal and will therefore give much better protection than other coatings such as paint. While protection by paint may have to be re-processed every 5 or 6 years, protection by galvanizing should last in excess of 30 years, even with exterior usage in coastal environments.
All structural steelwork is hot dip zinc galvanized to BS EN ISO 1461. Prior to galvanizing, all surfaces are cleared of oil, grease, rust, and debris. An environment category C3 is typically adopted, which achieves a minimum coating of 85μm. However, galvanizing can be adapted to suit specific environments by request.
