Is your roof too large to be done in pre-fabricated timber or are you shipping roofs into Africa and paying dearly for transport? Maybe you wish to supply low-cost roofs or simply prefer non-combustible roof structures? Whatever your need, Ultra-Span® offers the solution!

MiTek Industries South Africa (Pty) Ltd, the world’s leading provider of connection solutions to the wood component industry, is proud to present the Ultra-Span® Light Gauge Steel Truss System. Your local MiTek licensed fabricator can provide you with design and pricing information on Ultra-Span® utilising state of the art MiTek 20/20® software, alternatively your MiTek regional offices will gladly assist.

Ultra-Span® trusses can be supplied in “kit-form” (low-cost housing or other remote projects) whereby trusses are assembled on site, contributing to local skills transfer and employment, or in pre-fabricated form ready for installation on the roof.
