Austube Mills’ range of lightly-oiled products are coated to prevent short-term corrosion, specifically during transport between the mill and distribution centre.
The coating is mineral-based oil diluted with solvents and is easily removed by alkali solution or kerosene.
Unless used for benign corrosion environment applications (e.g. internal or behind finishes), the oil will generally need to be removed for further priming and top-coating. In terms of design lives for various atmospheric environments, oiled products behave in the same manner as uncoated steels.
Oil products can be fabricated normal workshop techniques. Forming, cutting, drilling and welding is the same as for uncoated tubular products. Standard pre-treatment processes will easily prepare the product prior to galvanizing.
