Black Squares FAQs

What is the difference between black square bar and a bright square bar?

Black square bars usually have a hot rolled mill finish and are suited to general fabrication. Bright square bars have a smoother finish and are often chosen where closer tolerances or a cleaner appearance are needed.

Is black square bar suitable for outdoor use?

Black square bar can be used outdoors, but it should usually be painted, primed, galvanised, or otherwise protected to help reduce corrosion.

Is black square bar suitable for welding?

Yes, mild steel black square bars are commonly used in welded fabrication. The surface should be cleaned before welding for better results.
