Standing Seam Profile – 1
Standing seam roofing is the most reliable roofing material. The risk of leakage is excluded due to concealed fixing, reliable seaming, and absence of through holes. Standing seam roofing blends into architectural character of cities thus being applied for new building construction as well as for remodeling and renovation.

Advantage
- On site rollforming thus providing single length sheet from Ridge to eve avoiding make weather.
- Tha channce of leakage is eliminated if roofing is properly seaned Easy and quick to install.
- Absense of throu8gh holes Prevents perforation corrosion both at joints and on surface thus ensuring for very low ultimate durability.
- Suitable for very low sloped Roofs.
- Standing seam profile roofs are used for low slope by means of single long sheets with no joints.
- This provides water tightness avoiding water leakage by 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 less maintenance.
- Standing seam profile is site fabricated using the color coated coils by means of roll forming machine and the sheets laid from the ridge to the gutter.
- No screws are used and hence long lasting.
- Offers excellent design flexibility.
- Mechanically seamed on the side laps.
- Long length full length sheets eliminate end laps.
- Can be produced and installed in lengths of up to 100m.
- Onsite production of the roof of 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).
