Section Translation Guide

The STG is an innovative web based calculation tool that can be accessed anywhere. The STG is the only online structural steel translation guide available in Australasia. It allows designers to undertake a performance comparison of cold formed hollow sections to hot rolled open sections with just the click of a mouse. It removes the need to consult lengthy guides and carry out complex physical calculations. The STG was created because Orrcon Steel recognised the need for a resource that would enable cost-effective design solution outcomes for engineers, architects and builders.

ALLGAL® is cold-formed structural steel hollow tube with a pre-galvanized zinc coating. It is manufactured using the ERW (Electric Resistance Welded) process and the zinc coating along the weld zone is restored using hot metal spray. It is finished with an organic clear coating to provide interim protection for transit and storage.

Orrcon Steel’s ALLGAL® zinc coated Tube and Pipe is suitable for many applications that require a high quality manufactured smooth and consistent surface protection.

Technical Resources

White rust is a white powdery deposit formed from a natural corrosion process that can occur on any new, zinc coated steel product. 

It is damaging to the appearance of the steel, not to mention to the anti-corrosion layer of zinc that protects the body of the steel. 

Zinc is a very durable coating for the purposes of providing sacrificial protection to the underlying steel substrate but, because it is reactive to water, great care must be taken in storing it correctly. That is why it is often referred to as “wet storage stain.”
