Stramit Speed Deck Ultra® Concealed Fixed Decking gives excellent durability in almost all locations. With all of its fastenings protected beneath the decking, Stramit Speed Deck Ultra® Concealed Fixed Decking can be expected to outlast through-fixed roofing. However, it is important to choose the correct coating for each application environment. Durability recommendations do vary based on the application of the product in roofing or walling installations.
All building products need to be checked for compatibility with adjacent materials. These checks need to be for both direct contact between materials, and where water runs from one material to another.
The following guidelines generally avoid material incompatibility:
Stramit's roofing and walling products should be handled with care at all times to preserve the product capabilities and quality of the finish.
Packs should always be kept dry and stored above ground level while on site. If the products become wet, they should be separated, wiped and placed in the open to promote drying.
The unique Stramit Speed Deck Ultra® Concealed Fixed Decking full width clip compresses blanket during installation making fixing easy. Blanket up to 100mm in thickness can be readily used. High thermal efficiency can be achieved by using Styrofoam blocks laid between the blanket and the fixing clips. Contact us for further information.
Stramit Speed Deck Ultra® Concealed Fixed Decking is supplied cut to length. When designing or transporting long products ensure that the length is within the limit of the local Transport Authority regulations.

Concealed fixed decking such as Stramit Speed Deck Ultra® Concealed Fixed Decking is the preferred roofing material in alpine areas. This, and many other design suggestions, can be found in Australian Standards HB 106 – ‘Guidelines for Design of Structures in Snow Areas’.
Particular attention is drawn to maintaining an adequate roof slope for snow shedding, and screw fixing of deck pans beneath the ridge capping. Downward load capacities for Stramit Speed Deck Ultra® Concealed Fixed Decking have not been tabulated, but can be assumed to equal the outward capacities shown.
Stramit Speed Deck Ultra® Concealed Fixed Decking has purpose made fixing clips to attach the decking to the purlins. These clips require 3 fasteners positioned between the clip upstands. Please refer to the instruction details to ensure correct operation.
All fastening screws must conform to AS3566 – Class 3.
For connecting clips to purlins:
The approved system consists of Stramit Speed Deck Ultra® concealed fixed decking 700mm effective cover sheets produced from hi-tensile steel with Class AZ coating to AS1397-2011 in plain or pre-painted finish.
The sheet has 3 ribs 233mm apart and must be secured using Stramit Speed Deck Ultra® clips, with each clip fixed to a steel support of minimum 1.5mm thickness using 3 Buildex® 12-14 x 30mm hex-head fasteners.
Fletcher Insulation Roof Rack® refers to both the 75mm and 100mm high spacers, which are fastened using 3 Buildex® 12-14 x 30mm hex-head fasteners to the minimum 1.5mm thick steel supports. The Stramit Speed Deck Ultra® clips are fastened to the Roof Rack® spacers using 3 Buildex® 12-14 x 30mm hex-head fasteners.

Foot traffic limits for Stramit Speed Deck Ultra® Concealed Fixed Decking are shown for 3 alternative foot traffic categories:
High Maintenance – for applications with repeated maintenance, particularly where personnel may be unfamiliar with correct procedures for walking on metal roofs.
Normal – based on traditional expectations, with moderate maintenance foot traffic using designated footpaths.
Controlled – spans that confirm to AS1562 but require minimal careful foot traffic only on the designated footpath. Suggested for use only where occasional aesthetic imperfections from foot traffic are acceptable.
Stramit Speed Deck Ultra® Concealed Fixed Decking is manufactured from G550 colour coated steel or zinc-aluminium alloy coated steel. In some locations galvanised and severe environment colour coated steel may be available by arrangement.
Colour coated steels are in accordance with AS2728 – Category 3 and, for the substrate, with AS1397. Zinc-aluminium alloy coated AZ150, aluminium-zinc-magnesium alloy coated AM100/AM125 and galvanised Z450 conform to AS1397.
The minimum roof slope for Stramit Speed Deck Ultra® Concealed Fixed Decking is 1 degree (1 in 60)
The spans shown below take account of normal foot traffic and wind resistance including local pressure zone effects. Pressures are based on AS4055 or AS1170.2.
Where the two standards differ, the worst case has been taken for each classification. Data should only be used for buildings 7m or less in height, 1000m2 or less in area and unaffected by land topography.
Stramit Speed Deck Ultra® Concealed Fixed Decking can be spring curved, concave and convex, including curved ridges, provided it is within the recommended limits below.
All metal roof sheeting is subject to thermal expansion and this needs to be accommodated where there is a temperature difference between the sheeting and the structure.
The colour of the sheeting will affect the amount of thermal expansion, and whether the sheet is flat or cured will affect its ability to resist without problems. Stramit Speed Deck Ultra® Concealed Fixed Decking has excellent resistance to the problems associated with thermal expansion, however sheet lengths should be limited as follows.
Stramit Speed Deck Ultra® Concealed Fixed Decking has excellent water-carrying capacity. This and the sheeting stiffness enable roof slopes to be as low as 1° for many applications.
Roof run lengths are the combined lengths of all roof elements contributing to a single pan drainage path. This can include the roof length upstream of a roof penetration that concentrates flow into other pans.
The table below gives slopes for 100 year return period rainfall intensity.
Derived from testing, the following tables give the wind load resistance for both serviceability and strength limit states.
Stramit's cladding can be easily cut, where required, using a power saw with a cold cut saw blade or a power nibbler and, for localised cutting, tin snips. Avoid the use of abrasive discs as these can cause burred edges and coating damage. Please dispose of any off-cuts carefully and thoughtfully.
The Stramit FarLap® roof lap joint is a patented revolutionary system that changes the way long run roof decking is designed and installed. It provides a multiple sheet option for long length concealed fixed roofing projects that eliminates traditional step joints or the need for long on-site rolled sheets, without compromising the integrity of the roofing structure.
Designed specifically for Stramit Speed Deck Ultra® Concealed Fixed Decking, the Stramit FarLap® roof lap joint system allows the installation of lapped sheets on standard purlin framing, without the need for conventional stepped jointing. The system provides a combination of a strong joint and a weather-resisting seal between lapped sheets.
The system is simply installed by clipping onto the ribs of the bottom sheet. The top, overlapping sheet is then pushed on to the Stramit FarLap® units, providing a structural connection. The joint connectors and sealing foam are manufactured from high technology materials that provide strength and weather-resistance and preserve the existing roofing warranty.
Stramit FarLap® roof lap joints can only be used with Stramit Speed Deck Ultra® Concealed Fixed Decking and with the following provisions:
Stramit FarLap® lap joints are readily installed on Stramit Speed Deck Ultra® decking. No additional fasteners are required. Stramit Speed Deck Ultra® Concealed Fixed Decking sheets are installed in the normal manner, except that:
When installing the Stramit FarLap® units:
Stramit Speed Deck Ultra® Concealed Fixed Decking is readily installed with or without fibreglass insulation blanket. If practical lay sheets in the opposite direction to prevailing weather.
Installation of Stramit Speed Deck Ultra® Concealed Fixed Decking is a straightforward procedure using the following fixing sequence.
For use in conjunction with Stramit FarLap® joint system, Stramit Skylap® joint is only suitable for the fibreglass over fibreglass joint and the edge joint of the fibreglass over Stramit Speed Deck Ultra® decking joint.
Fibreglass sheet overlaps should be a minimum of 350mm as per the normal Stramit FarLap® recommendations. Stramit's Skylap® documentation outlines installation instructions.
Free underlap sheet edges may be encountered when using translucent sheeting, may need additional support. Use a 40mm x 40mm x 1.0mm trim angle beneath the underlap and screwed to the purlins if spans exceed 1500mm for 0.42BMT, and 2000 for 0.48BMT.
