EN-Construction-Product-RoofDek - D100 | Structural profile specification

Structural profile specification
RoofDek Tata Steel construction decking

RoofDek D100 is part of our deep deck profile range which has exceptional strength and span capability, providing a rugged structural platform for all roofing types. They are ideal for large span buildings where they reduce the need for purlins.

1. When RoofDek is supplied with Colorcoat HPS200 Ultra® pre finished steel, the above load span tables do not apply. Please contact our technical team for the load span tables in this instance.
2. Calculations accord to Eurocode, however a fixings check is also required.
3. Load table is based on the deck bearing onto 100mm min flange steel beam.
4. For maximum Load/Span in double span conditions, contract the technical department.
5. The Interior Liner colour on D135, D153 and D200 is RAL9002.

RoofDek quick selector

The increasing complexity of roof decking projects makes any software aimed at easing the process very welcome indeed.

To aid this, Tata Steel introduced the RoofDek quick selector, a web based structural analysis tool. It allows a user to rapidly select the most appropriate deck for the application and structural requirements using a PC or tablet, including iPad.

The software provides an optimised RoofDek specification, and it also allows the user to choose an alternative RoofDek profile. The RoofDek quick selector page contains pre-populated span and load figures as an example, but users can then modify these to their own requirements to find the right decking profile for a given project. All calculations are carried in accordance with Eurocode 3 on one screen and may be printed out as a record of the design.

The RoofDek quick Selector augments Tata Steel’s suite of roof decking software, which includes RoofDek Analysis Software.

RoofDek Analysis Software, Powered by Tekla Tedds

Our RoofDek Analysis Software has been created in partnership with leading software developer, Trimble, using their widely-adopted structural calculation software, Tekla Tedds, as the platform for the deck analysis software.

This software compliments and enhances our RoofDek quick selector, allowing users to conduct full deck analysis.

It also completely satisfies the need to comply with Eurocode 3 Design of Steel Structures and Eurocode 9 – Design of Aluminium Structures.

Users are able to input up to four spans, two of which can be cantilevers. Extended end laps can be included as internal supports. Thickness of deck can be varied each side of extended end laps.

Design support

We maintain a friendly technical help desk which is freely available to all architects, engineers and contractors to assist with all aspects of RoofDek and liner tray design. The services we offer include:

Specification service - Our RoofDek team are able to provide a comprehensive specification service. Assistance in creating NBS specifications for RoofDek and trays can be provided to ensure the correct deck or tray is specified for the right application.

Design calculations & diaphragm design - To assist the specifier, the team are able to provide design calculations for live, dead, wind and snow drift loads and where required diaphragm design calculations.

Sound absorption and reduction - RoofDek perforated decking provides excellent sound absorption characteristics, our technical team can provide details of systems tested for both absorption and reduction. We also offer indicative acoustic calculations on differing build ups.

Roof Safety - Our technical department can provide details of non fragility performance of the RoofDek itself and the use of fall prevention and fall arrest systems on RoofDek roofs.

Inhouse CPD seminars - Primarily aimed at engineers and architects, these free seminars last around 50 minutes, ending with a question & answer session and are delivered by our experienced regional teams.

Topics include:

  • Structural roof deck in construction
  • Composite floor deck in construction
  • Sustainable steel cladding refurbishment solutions
  • Factory tour of Insulated panel lines
