Secret Fix Roof Profile
What is a Secret Fix roof system?
Secret Fix systems involve the mechanical fixing through the underlap of the profile into the roof structure, which is then covered over by the overlap of the profile. This removes any chance of leaks through the roof sheets as all penetrations are protected from weathering.
SF500 gives the Specifier and Contractor a proven and simple system to use for low pitch roof applications, where speed of fixing and guaranteed performance are required and continuity of finish, colour and material choice are paramount. SF500 has been specifically designed to function at design pitches down to 2.5° (minimum actual pitch 1°), with no external penetration of the sheet, no end laps and low maintenance performance. Manufactured predominantly in HPS200 coated steel, the system offers many of the advantages of a true standing seam system, but is simpler to install and may be more simply integrated into projects where the material of choice is steel rather than aluminium.
Sheets can be rollformed on site, therefore long lengths, eaves to eaves are possible giving excellent watertight covering. The SF500 sheet can self curve to a 50 metre radius.

NBS draft specifications are provided for all standard constructions and can be tailored to suit project performance requirements through consultation.
This service draws on Euroclad experience and the flexibility of built-up systems, to respond to individual requirements for specific thermal, acoustic, structural and other performance considerations. SF500 provides superb weathering performance through a precision engineered snap fit 55mm overlap. The underlap is designed to take a 3mm bead mastic seal, whilst the low profile pan allows excellent drainage at low pitch. Single eaves-to-eaves or ridge-to-eaves sheet lengths with no end laps and no external fixings penetrating the sheet, along with on-site manufacture, means that sheet lengths are effectively limited only by handling requirements. Carefully designed accessories and details ensure no compromise of performance. The structurally – tested system and longevity of materials provide long-term security.
