DuraGal® Clear RHS and SHS Galvanized Steel

InfraBuild Steel Centre stocks DuraGal® Clear RHS (rectangular hollow section) and DuraGal® Clear SHS (square hollow section) galvanized steel products.

DuraGal® Clear RHS and DuraGal® Clear SHS supplied by InfraBuild Steel Centre are high-strength cold formed hollow steel sections that are hot dip galvanized to AS/NZS 4792 and have a minimum average coating mass of 100 grams per square metre applied to the interior and exterior of the sections.

DuraGal® Clear sections are also prepared with a non-chromate passivation treatment which, when combined with appropriate pre-treatments, passes the permeability test specified in AS 4506.

All DuraGal® Clear sections are available as C450PLUS structural tube. C450PLUS structural tube achieves the highest strength grade, C450L0, of AS/NZS 1163, while maintaining the elongation and formability of C350L0, providing no loss of ductility or workability.

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.
