Description

SR structural roof deck is available in a range of depths from 30 to 100 mm, offering design flexibility for various structural applications. These profiles can be used for short spans between purlins or longer spans onto hot-rolled steel beams, depending on project requirements.

SR profiles are commonly integrated into built-up roofing systems, including single-ply membranes, double-skin systems, standing seam assemblies, green roofs, and asphalt finishes.

R733 SR steel is produced in state of the art Electric Arc Furnace (EAF) facilities, using 100% recycled scrap material and powered exclusively by fossil-free electricity. This approach significantly reduces embodied carbon without compromising mechanical performance or long term durability.

Features and benefits:

  • Can be manually installed with limited need for additional lifting plant.
  • Perforated option available for enhanced acoustic performance.
  • CE/ UKCA Certified.
  • Low embodied carbon.

Profiles:

  • SR30+ (0.7 or 0.9 mm);
  • SR35+ (0.7, 0.9 or 1.2 mm);
  • SR60+ (0.7, 0.9 or 1. 2 mm);
  • SR100+ (0.7, 0.9 or 1.2 mm).
