What is a Pitch Roof Truss System?

A pitch roof truss system (also called A-frame or saddle roof truss) is a triangular roof structure designed for outdoor stage applications, providing improved load distribution, rain drainage and wind resistance compared to flat roof systems.

This is the standard structure for outdoor concert stages

Engineering Insight

When choosing between flat roof vs pitch roof, the key differences are:

• Flat roof → simpler, indoor or low-risk use

• Pitch roof → safer for outdoor use (wind + rain)

For outdoor stages, pitch roof is the standard choice
