This product is an all purpose galvanised steel tube. It’s applications are virtually limitless, having been used for just about everything from fence posts and truck bodies through to airport terminals. Galvanized steel is a type of steel that has been galvanized through the application of a zinc coating throughout its body so that it can be protected from corroding or rusting. Galvanized steel has a longer life and durability compared to non-galvanized steel. Galvanized steel is rustproof without additional coating while primed steel requires additional coatings to protect against corrosion.
