The system also includes a complimentary straight panel. The straight panel can construct pitched roofs and walls.

Spantech panels are manufactured on site. It makes construction fast and efficient.

Value for Money and Whole of Life Cost

The Spantech Construction Systems are specifically designed for large commercial projects.  Spantech presents excellent value for money for any commercial project.

Capital Cost

  • We manufacture our profiles on site to minimise transport and handling and reduce waste.
  • Our wide-span roofing systems significantly reduce the total amount of structural steel in the project.
  • Spantech construction systems are fast and very efficient to construct.
  • Excellent quality assurance system.

Ongoing Costs

  • Spantech profiles are manufactured with base metals up to three times thicker than conventional roofing.  So our profiles perform better and last longer than conventional roofing profiles.
  • Conventional roofs are secured with fasteners penetrating through the profile.  Each penetration is a potential cause of a leak or corrosion.  All Spantech profiles are connected together without fasteners maximising the effective life of our roofs.
  • Our roofs require very little maintenance, significantly reducing the whole of life costs of Spantech buildings.
