Structural Roof Decking
Description

A range of structural roof decking sheets of various profile depths manufactured in steel and aluminium capable of large spans and designed to support slab insulation and an external membrane to provide a flat insulated roof.

Features:

  • Wide range of profile depths and metal thicknesses.
  • Variety of finishes available as standard to one, or to special order both sides of the sheet.
  • Spans may be increased by using multi (three or more) spans rather than double spans, or by providing extended end laps.
  • Full load span information is available on the Tata Steel Panels and Profiles website or from the company technical department.
  • Can act in diaphragm to minimize bracing steelwork.
  • Available fully perforated or with perforated webs to provide acoustic absorption; non standard perforation patterns may be available.

Roof deck profile ranges:

  • Standard – Combines economy with aesthetics and structural performance.
  • Special – Further profile sections deemed 'specials' complementing the standard range. Maybe subject to minimum order requirements and extended lead times.

Fixing:

  • D32S, D35 – Main fixings at ridge and eaves at every pitch*, main fixings (intermediate) at every other pitch, side lap fixing is not essential.
  • D46, D60, D100+ – Main fixings at ridge and eaves at every pitch, main fixings (intermediate) at every pitch, side lap fixing at 450 mm centres, or as determined for diaphragm design.
  • D210 – Main fixings at ridge and eaves at every pitch, main fixings (intermediate) at every pitch, side lap fixing at 450 mm centres.

* Every other pitch is based on always starting with a fixing in the first pitch of every sheet, and a profile pitch of 200 mm or less.

Fully perforated decks and non standard perforation patterns are available to special order. In such cases Tata Steel Panels and Profiles should be consulted to establish suitability and to determine the structural properties of the deck.

Finish:

  • The standard finish for aluminium deck sheets is stucco embossed. Other finishes are available to special order and may be subjected to a minimum order quantity and extended lead times. Consult Tata Steel Panels and Profiles for details
  • Some standard roof deck profiles are available to special order with a coating on top and soffit sheet faces. Minimum order quantities may be required. Consult Tata Steel Panels and Profiles for details.
