Black CHS Steel (Circular Hollow Section Steel)
Liberty Metalcentre (formerly OneSteel Metalcentre) stocks a wide variety of black CHS steel. Black CHS steel tubes are high-strength, cold formed hollow sections, coated with a mineral-based finish that is easily removed by an alkali solution or kerosene.
Unless used for benign corrosion environments, the coating will need to be removed for further priming and top coating. Black CHS steel can be fabricated using normal workshop techniques. Standard pre-treatment processes will easily prepare the product prior to galvanizing.
Typical Uses
- Agriculture engineering
- Construction manufacturing
- Mining investment
- Non-residential construction
- Residential construction
- Transport and storage
Features
- Mineral-based finish, which can be easily removed prior to fabrication
Relevant Standards
- AS/NZS 1163:2009
