British Purlins Rail Systems – Intermediate Support for Structural Stability

At British Purlins, our Rail Systems Intermediate Support solutions ensure optimal structural integrity for cladding rails spanning over 2.5 meters. Intermediate supports play a crucial role in enhancing load distribution, preventing excessive deflection, and maintaining overall stability.

Key Intermediate Support Guidelines

Intermediate struts with diagonal ties are used to reinforce longer spans.
Struts are positioned based on span length:

  • Midpoint support for spans up to 6.1m
  • Third-span support for spans up to 9m
    For spans exceeding 9m, consult our Technical Team for customized solutions.

Midpoint & Third-Point Support for Side Rails

Midpoint Support – Recommended for spans up to 6.1m, positioned at the center of the span.
Third-Point Support – Used for spans up to 9m, positioned at third-span intervals for enhanced structural reinforcement.

📌 Diagonal Tie Wires are required to meet anti-sag minimum requirements for roof slopes exceeding 20m.
