Description

Steel profiled roof decking, developed to optimize the designer's needs for efficiency, aesthetics and structural performance alongside high strength and span capability.

RoofDek trapezoidal profiles D32S to D60:

  • Self-curving, within defined radius limits down to 40 m (see technical literature for further details).
  • Can be supplied crimp curved down to 400 mm radium. Maximum 5 m length, with a minimum straight 200 mm lead in and lead out legs.
  • Maximum cantilevers assume 0.9 kN point load on the end, with the adjacent span being the single span as shown in the load/span table separately. The end of the cantilever must be stiffened with an angle flashing.

RoofDek trapezoidal profiles D100 to D210:

Sheet lengths in excess of 12 m are not practical for installation on-site and may also be subject to delivery restrictions. Extended end laps can be used to create a double span whilst keeping the deck length to a minimum. If a deck length in excess of 12 m is required, consult the manufacturer.

RoofDek liner tray profiles HLT90/600 to HLT145/600:

Structural liner trays provide a neat planar inner surface spanning across the main steels and obviate the need for purlins or cladding rails. They are suitable for both roof and wall cladding.

Sheet lengths in excess of 12 m are not practical for installation on-site and extended end laps cannot be used with liner trays, so double spans are limited to 6 m.

Features and benefits:

  • Subject to satisfactory fixings, the decks will resist wind uplift to at least 1.50 kN/m² to a deflection limit of L/150.
  • Load/ span tables are calculated to Eurocode 3 and based on a combined imposed load of 1.50 kN/m², a construction line load of 1.5 kN/m and a deflection limit of L/200. The factor of safety used is 1.5 for live load and 1.35 for dead load.
  • Loss Prevention Certification Board (LPCB) LPS 1181-1 approved.
  • CE marked (2273-CPR-0036).
  • FM approved (0.9 and 1.2 mm galvanized Shotton made RoofDek. 3055902).

Applications:

Suitable for all roofing types.
