Shade Structures


Wide Span Building Systems

The company’s wide span building technology centres on a range of unique metal profiles invented by Spantech:

  • Wide span curved roofing profiles
  • Long span straight roofing profiles
  • Composite formwork systems
  • and coming soon – light weight structural beams.
Wide Span Curved Roof


Wide Span Curved Roofing

The Spantech Construction System features two unique metal profiles: the Woomera 300 and the Pinkenba 370 profiles.

Both are used to create wide span curved roofing without using trusses or internal columns. The panel can span self-supported up to 40m wide. The result is a dynamic frameless wide-span building.

Skillion Roof Profile Design


Long Span Skillion Roofing

Recently added to the product line-up, Spantech’s new innovative skillion roofing and wall cladding system is the Spantech Longreach 650 and Spantech Longreach 800 profiles.

These distinctive deep profiles give architecturally designed buildings a bold modern roof line and unique architectural appeal.



Composite Metal Formwork

Spantech has just released the Formwork 300, a composite metal formwork system. The system is a fast, cost-effective way to build high rise residential apartments, commercial office buildings and multi-level car parks. Find out how to save time and reduce your construction costs with Formwork 300.
