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
