SR60+ - Trapezoidal Roof Deck Profile

Premium sinusoidal profile for industrial, commercial and distribution roof systems. Cover width 850mm, 60mm depth, engineered for spans up to 5.2m with proven load performance across three steel gauges.

Available in galvanised and polyester white finishes. Supplied to BS EN 10346:2015. Complies with BS 5427:2019 for material and BS 476 Pt7 for fire performance (Class 1).

SR60+ is designed for modern roof decking applications where strength, durability, and speed of installation are key. Its profile depth and wide coverage make it ideal for commercial, industrial, and large-scale residential projects.

The underside can remain exposed for an industrial aesthetic, or specified with polyester white coatings to create a brighter soffit finish and reduce the need for additional lining.

  • Efficient Spanning Capability

    With a 60mm profile depth and gauges of 0.7mm, 0.9mm and 1.2mm, SR60+ is engineered to span longer distances with fewer supports. This reduces secondary steelwork, saves installation time, and provides cost-efficient roofing solutions.

  • High Load Capacity

    Thanks to its optimised section properties, SR60+ handles both gravity and uplift loads effectively, ensuring strength and stability even under demanding conditions.

  • Corrosion Resistance

    Offered with galvanised coating (Z275) or polyester white finishes, SR60+ is suitable for a wide range of environments, from standard commercial roofing to high-spec industrial applications.

  • Long Lengths: Manufactured in lengths up to 12m, reducing the number of joints and speeding up installation.

  • Long Lengths: Manufactured in lengths up to 12m, reducing the number of joints and speeding up installation.

  • Straightforward Fixing: Every trough requires main fixing at supports, with 150mm end laps, providing quick and secure installation.

  • Optimised Handling: At 850mm cover width, SR60+ offers excellent sheet coverage while remaining lightweight for on-site efficiency.

  • Reliable Side Laps: Installed at 850mm centres for enhanced stability and performance.

BUILDS

Features

Cover Width & Pitch

850mm cover width; 213mm pitch. Sinusoidal crown and valley geometry with 100mm and 62mm radii respectively.

Steel Grade & Thickness

S350 (BS EN 10143:2016, BS EN 10346:2015) in 0.7, 0.9, 1.2mm gauges. Maximum sheet length 12m.

Coatings

Galvanised Z275 (275g/m²) or Polyester White (150g/m² Z150 base + 25μm polyester topcoat).

Fire Performance

Class 1 (BS 476 Pt7); Class 0 surface rating available. Complies with BS 5427:2019.

Span Capability

2.0–5.2m depending on gauge, load case and deflection criteria. Partial safety factor 1.5 applied.

Fixing & Lap Details

Fixed every trough at sheet end; 150mm end lap, intermediate fixing every trough, 450mm side lap and 450mm side support spacing.

Benefits

Proven profile design: The 60mm depth sinusoidal profile provides excellent structural stiffness whilst maintaining practical cover widths and pitches. The 213mm pitch and curved crowns (100mm radius) and valleys (62mm radius) deliver both load capacity and weather performance.

Long span capability: SR60+ achieves spans from 2.0m to 5.2m depending on gauge and load case, reducing the need for intermediate supports and lowering support frame costs.

Material choice: Available in three gauges (0.7, 0.9, 1.2mm) from a single production line. Steel grades to BS EN 10143:2016 ensure consistent mechanical properties. Galvanised (Z275) and polyester white (Z150 + 25μm) coatings provide durability in exposed environments.

Fire compliance: Class 1 (BS 476 Pt7) and Class 0 surface rating where specified, supporting building regulations for medium-to-high-risk properties.

Applications

Industrial Facilities

Manufacturing plants, warehouses, factory units and production halls where robustness and long-span capability are essential.

Commercial Buildings

Retail, office canopies, terrace covers and extension roofing where aesthetic finish and weather tightness combine with structural performance.

Distribution & Logistics

Large-span sheds, storage facilities and consolidation centres requiring rapid installation and cost-effective roofing solutions.

Plant Room Enclosures

Covered plant areas including pump houses, boiler rooms and external equipment shelters with robust weather protection.

Roof Refurbishment

Re-roofing existing industrial and commercial structures where rapid installation minimises downtime and disruption.
