Trapezoidal Roof Mounting Mounting System May 12, 2021

Solar metal roof pv racking with clamps are non-adjustable clamp for trapezoidal metal roofs, equipped with 2 bolts and EPDM washers, suitable for all common trapezoidal metal roof profiles. It is designed according to the width of the crown of a specific roof profile, and the height is not adjustable at the bottom to connect to the bottom mounting rail system.

Feature of solar metal roof mounting with bracket:

  1. Non-adjustable clamps can be adapted to specific trapezoidal metal roof panels;

  2. High strength aluminum alloy material with anodized surface treatment;

  3. 10 years warranty and 25 years service life;

  4. Waterproof EPDM rubber;

  5. High pre-assembly bracket, it can save labor costs at the installation site.           


Considerations for PV energy system installation on trapezoidal roof:

First :Water tightness. The first and most important consideration is waterproof as any building owners want peace of mind that they won’t have a leaky roof. For this reason, it is common practice for thin sheet screws or rivets to include a neoprene or EPDM washer to create a water tight seal around the roof penetration.

Second: Metal sheet thickness. The thickness of trapezoidal sheets often sit between 0.5 and 1mm, however there are some sheets on the market now which are <0.5mm. The pull-out strength of the fixings required will change with the thickness of the sheeting; for example, as thin sheet screw will have a higher pull out force on a sheet that is 1mm thick compared to 0.5mm thick. This can impact on the number of fixations required to make a system safe against extreme wind forces so correct information is critical.

Third: Panel orientation. As with any PV project the decision to place the modules in portrait or landscape orientation can be influenced by many factors such as; system performance, roof tilt/pitch, roof orientation or roof obstructions.
