Overview
trisobuild cr roof system tata steel construction curved roof

The Trisobuild® CR system is a tried and tested assembly with a through fixed trapezoidal outer sheet which can self-curve around a range of radii. The system is specified with an apex sheet long enough to ensure that the end lap of the profile or roof light is below the 4 degree pitch of the curve.

Designing the roof and using Trisobuild® CR within this radius range allows the specifier to optimise cost and provide an attractive low profile roof, with the confidence that all detailing has been third-party assessed.
