Choosing the right profile sheeting can be a daunting task, since there are so many to choose from. LCP Roofing offers tips and advice to make selecting your roof covering easier.
There are two types of roof sheeting categories, namely pierced fix and concealed fix. The pierced fix profiles from different suppliers are all quite similar in design, whereas the concealed fix sheeting is where the major differences lie. While the basic principle of the concealed fix sheeting remains, each supplier has patented concealed fix profiles with special fastening clips.
Choosing the profile that best suits your project depends on the project requirements. Another factor to consider is the effective cover of each profile, which has budgetary implications, and the different materials that might make up each supplier’s profiles.
The most common profiles and their most suitable applications:
Pierced fix profiles:
This category of sheeting profiles includes all sheeting that is erected using fasteners that pierce the sheets at set intervals to fix to the roof purlins.
This is the most common profile of sheeting in the industry today. It is easy to erect and requires little effort to maintain. Due to the narrow flute and small height of this profile, it is ideal for high pitch residential roofs. It is also an easy profile to use as cladding. It has a beautiful uniform look with minimal accessories required. The minimum pitch required to ensure no waterproofing issues is 10°.
IBR is the abbreviation for Inverted Box Rib. This is also a common profile, and has many variations of design per supplier. This sheeting is mostly used for patio or carport sheeting. Due to the design, it can be used on residential roofs as low as 5°. This profile also works well as cladding. It has a more edgy look compared to corrugated sheeting. It is easy to erect but it requires more accessories, due to the height of the flute.
The concealed fix profiles are design-specific to suppliers. The basic principle remains the same. This profile can be used on roofs with a pitch as low as 3°. This profile is ideal for very long sheets at a flat pitch. The higher the pitch, the more likely oil canning may occur. This profile makes use of a clip that is fastened to the purlin after which the sheets clip onto it. This means there are no fasteners piercing the sheet, which gives the sheet a smoother look coupled with the rugged edges of the profile.
There are many more different profiles of roof sheeting available on the market from different suppliers. Choosing the profile depends on the project requirements, rainfall in the region, wind speeds and ultimately the aesthetics of the roof. All these factors are clarified in the supplier catalogues readily available on the internet and from the suppliers.
