The panel can be used for curves and flat cover, ensure water tight seal event with minimal slope.  All the colors come with 1 side of coated U.V. protection: their High-resistance pigments are added to the polycarbonate to achieve different light transmission values. 

The sheets are connected to each other by long connecting elements colled H Profile. For this sheet we recommend an Aluminum H structure:

Aluminum structure
It is composed by a base and cap aluminum profile that must be directly fastened to the structure

Sheets must be be fastened to the structure using specific washers with a seal to guarantee a watertight finish and allow the material to expand due to changes in temperature. For proper point fastening sheets should be all fastened to supports at all four corners and at points 6" in from the edges of each purlin support. 

In order to prevent dust and dirt penetrating inside the ribs, the exposed top and bottom ends of a sheet must always be sealed first with the solid aluminum tape on the top and vent tape at the bottom, than with the proper "U" profiles that you can choose to have in aluminum or polycarbonate. 

*ePlastsUSA gives you advice regard contruction and roofing in particular. Therefore, the full responsibility for the installation of panels, the proper attachment between the panels themselves and between the panels and parts of the structure, as well as the full support of the panels against natural forces and standard building loads remains with the roofing and the constructor.
