Planning a Multiwall Supporting Structure

When planning a polycarbonate twinwall or multiwall supporting structure, we have a few important tips to keep in mind.

Supporting beams for polycarbonate multiwall structures must be at least 30mm (1.18") wide to ensure good anchorage of sheets and fastening accessories. In the case of an arched structure, check the smallest permissible cold bending radius according to the sheets' thickness.

Your polycarbonate twinwall sheets should be installed with the ribs parallel to rain flow, allowing water to flow throw the flutes if needed. A supporting structure must have a roof slope of at least 10 degrees.

In gable and wall applications, always ensure that the ribs are positioned vertically.

Complete all the metalwork and painting before beginning sheet installation work. Check the dimensions on site, and plan the roofing requirements before beginning installation.
