Concealed Fix (Secret Fix)  Roofing Sheet Rollformer 

Concealed Fixing is a method where the roofing sheets are fixed to the purlins with a clip system.

The roofsheeting hides the clips completely and provides a neat, watertight product.

The roofsheets are not pierced with any nails or screws.

No holes are made in the roof covering; this is to eliminate the risk of leaks.

These sheets not being perforated also accommodates for expansion and contraction of the sheet without damaging the material.

This method is also designed to provide a continuous length of roof covering without end-laps.

Concealed fixed roofs are finished off with clean lines and there are no visible fixings.

It is very important that this profile is produced on a machine using a good roll design to eliminate any possibility of the profile changing during the manufacturing process.

As this could cause a problem when not seating onto the clips correctly and possibly later blowing off any roofs.

There are a variety of different concealed fix profiles on the market and we produce machinery for any one of these.

In many cases these machines are built into trailers to take to building sites to produce long sheets which are not transportable if manufactured off site.

Regardless of the profile or the conceal fix system, certain critical dimensions need to be strictly adhered to.

There are profiles ranging from a single pan to multiple pan applications, from snap lock to clip lock and from a 200mm to a 1000mm cover sheet width.
