Application

Roof deck designed for application in industrial and mechanical environments, commercial and office developments, educational institutions, retail spaces, distribution centres, and transportation infrastructure projects

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).
