Seam Roofing

The Optimal Solution for Wide Spans

Seam-system roofing, which provides a flawless and optimum solution for wide-span and circular-section roofs, is applied in two different options: Trapezoidal Seam and Flat Seam.

In the seam system, metal sheets are joined with clips instead of screws, eliminating future water-insulation problems caused by screws. Produced on site as a single piece from ridge to eave (or eave to eave), the covering delivers zero-problem results on wide-span roofs.

In the flat-seam system, since the load-bearing lower layer is trapezoidal, it can be easily applied on the Z-profile system built over the lower trapezoidal layer in systems solved with wide-spaced (150 cm and above) purlins.
