With only a few components, our MRD Mini system can be easily fixed directly into the trapezoidal profile sheet, to create a secure and simple mounting system for the solar panels.
Each stainless steel, self-drilling screw achieves 1.1kN minimum uplift resistance from 0.5mm steel. There are 4 screws per MRD Mini piece, which means there is a minimum uplift resistance of 4.4kN per rail. This ensures that the system is securely fastened to the roof.
We use EPDM to cushion the mounting rail against the roof, which creates a separation layer between the different materials and avoids any chemical reactions from occurring. With its 650kPA tensile strength and its high performance in resisting UV, we use the EPDM for a secondary purpose to provide a weatherproof seal around the fixings. This EPDM layer is applied prior to delivery.
We’re fully in support of the MCS 012 certification requirement on pitched roof mounting systems, which came into force in 2014 and since then we’ve followed every significant step to comply and give substance to the scheme.
Our module clamps are universally suitable for all solar panels depths and what’s more, they’ll arrive to you pre-assembled, allowing you to keep on schedule when it matters the most. They’re also available in black.
