Advantages
- On-site roll forming thus providing single length sheet from Ridge to eve avoiding make weather.
- The chance of leakage is eliminated if roofing is properly seaned Easy and quick to install.
- The absence of throu8gh holes Prevents perforation corrosion both at joints and on the surface thus ensuring very low ultimate durability.
- Suitable for very low sloped Roofs.
- Standing seam profile roofs are used for low slopes using single long sheets with no joints.
- This provides water tightness avoiding water leakage by the usage of sealants and interlocking of the double lock type clips in the seams.
- It simplifies the roofing installation and faster installation.
- Preferred mostly architects and MNCs for their aesthetic beauty and very little maintenance.
- No screws are used and hence long-lasting.
- Standing seam profile is site fabricated using the color coated coils using a roll forming machine and the sheets laid from the ridge to the gutter.
- Offers excellent design flexibility.
- Mechanically seamed on the side laps.
- Long-length sheets eliminate end laps.
- Can be produced and installed in lengths of up to 100m.
- Onsite production of the roof eliminates damage to the sheets.
- Fire-rated and light-weighted.
- Standing seam roof can be laid in single skin or using insulations.
- Condensation-free, durable, and corrosion resistant.
- FM approved (USA).
- Very much preferred by EPC consultants and PMC companies.
- Very much energy efficient and contributes to LEED and Pearl rating certification.
- DBIT approved (Germany).
