Black CHS Steel (Circular Hollow Section Steel) Tubes
InfraBuild Steel Centre 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: Cold-formed structural steel hollow sections

How we're making an impact.
Circular steel manufacturing
We recycle scrap steel and transform it into new steel products through a continuous circular process. Keeping materials in use reduces waste and supports resource efficiency.
Renewable energy transition
We're increasing the use of renewable electricity across our operations as part of our decarbonisation pathway. This helps reduce emissions associated with steel production.
Lower embodied carbon solutions
Innovations such as SENSE 600® help customers reduce material use while maintaining structural performance. Less steel can mean lower embodied carbon outcomes.
Local manufacturing
Manufacturing steel in Australia strengthens sovereign capability, reduces supply chain complexity and supports local jobs and communities.
1.4M tonnes
of scrap steel recycled annually
77%
fewer greenhouse gas emissions from electric arc furnace steelmaking compared with traditional blast furnace steelmaking*
Building more sustainably starts with making better use of materials.
SENSE Solutions® combines five capabilities to help customers build more with less: products, engineering expertise, digital tools, productivity intelligence and verified sustainability data. Together, they can reduce material use and embodied carbon, improve construction productivity and lower overall project costs.
