Our unique, patented Bracketless Portal System is constructed using cold-formed flat Z450 galvanised coil.
Typical clear spans range from 9m to 30m, with no obtrusive knee or apex braces.
Primary and secondary sections are fully-bolted (not TEK screwed), and nested purlins are bird/vermin-resistant.
The Bracketless Portal System is an exclusive patented design, created by Coresteel Buildings in 2005.
The system allows steel columns and rafters to be nested together and directly bolted, rather than being joined with a bracket. This system produces a stronger connection without the need for additional obtrusive knee-bracing.
Our system supports buildings of virtually any size and allows you to make the most of your internal space.
