Description

Aluminium 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 D35 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 radius. 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 D159:

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.

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 9 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).

Applications:

Suitable for all roofing types.

Standard product features

Material:

Aluminium alloy to BS EN 485-1/2/3/4:1995. Coated grade 3004 H44. Mill and stucco - grade 3005 H27. Consult manufacturer for the availability of types of coating or finish which depends on profile and other factors.

Depth of deck:

The profile reference indicates the depth of the deck, e.g. D100 = 100 mm deep.

Fire performance:

  • Surface spread of flame: Class O.
  • Reaction to fire performance: Dependent upon pre-finished steel product up to A1 rating to BS EN 13501-1 (considered non-combustible).
  • Ratings for exposure and penetration to fire, dependent on build-up above deck.

Technical characteristics:

Varies depending on material and thickness, consult technical literature for weight, single and double span data, plus minimum self-curve and cantilever information.
