Description
Steel perforated web roof decking to provide acoustic absorption, acoustic reduction (rating A–D) and structural support.
Fully perforated decks also available, consult the manufacturer for details.
Features and benefits:
- Load/ span tables are calculated to Eurocode 3; however, a fixing check is also required.
- 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).
Acoustic RoofDek trapezoidal profiles D46 to D100:
D46, D60 and D100 use perforating pattern 4546, 4.5 mm holes at 6.3 mm triangular centres. Pattern open area: 46%.
Acoustic RoofDek trapezoidal profiles D137 to D200:
D137 and D159 use perforating pattern 3327, 3.3 mm holes at 6 mm triangular centres. Pattern open area: 27%. D153 and D200 use perforating pattern P3L-S, 3 mm holes at 5.5 mm square centres. Pattern open area: 23.5%.
RoofDek liner tray profiles HLT90/600 to HLT145/600 perforated:
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.
Liner trays use perforating pattern P3L-S, 3 mm holes at 5.5 mm square centres. Pattern open area: 23.5%.
Depth of deck:
The profile reference indicates the depth of the deck, e.g. D100 = 100 mm deep.
Fire performance:
- 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.
Profile:
- Cover area: Plan area of the soffit.
- Exposed area: Total area metal exposed.
Finish:
- Colorcoat HPS200 Ultra®:
Recommended for applications in indoor ambience category A3, A4 and A5. Refer to Tata Steel Colorcoat HPS200 Ultra® technical brochure for further information.

Recyclability | All steel elements are recyclable, with ‘end of life’ assumptions for recovered steel and steel recycling being 89% of steel is recycled, 10% of steel reused with 1% loss |
Recycled contentAs defined in clause 7.8 of BS EN ISO 14021 | 16.1 % Manufacturer guidanceThe concept of recycled content is a useful metric to stimulate economies of scale around recycling of materials which may otherwise be incinerated or land-filled. But this is not the case for steel. Steel has been recycled for over 150 years and the recycling process and infrastructure is efficient and economical without any added stimulus. Scrap steel is valuable, so wherever it can be recovered it is, and very little steel ever goes to waste.
Provided this is understood we can confirm for the financial year 22/23 Tata Steel UK produced 2.93 million tonnes of crude steel, recycling 0.472 million tonnes of steel scrap. This equates to a recycled content of 16.1%. A breakdown of the scrap by source shows that ~12.5% was internal pre consumer scrap. The remaining ~3.6% was externally sourced commercial scrap. As the exact mix of the scrap cannot be fully determined it is not possible to define this as pre/post-consumer scrap per the LEED v4 definition. |
