Efficient spanning: a 60mm depth in 0.7mm, 0.9mm or 1.2mm gauge spans longer with fewer supports, reducing secondary steelwork, saving install time and keeping roofing cost-efficient.
High load capacity: optimised section properties handle both gravity and uplift loads effectively, staying strong and stable under demanding conditions.
Corrosion resistance: available galvanised (Z275) or polyester white, suiting everything from standard commercial roofing to high-spec industrial applications.
Long lengths: manufactured up to 12m, reducing joints and speeding up installation.
Straightforward fixing: main fixing in every trough at supports with 150mm end laps for a quick, secure install.
Optimised handling: 850mm cover width gives excellent coverage while staying lightweight for on-site efficiency.
Reliable side laps: installed at 850mm centres for added stability and performance.
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.
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.
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.
