[Case Study] Installation of Solar Mounting Structures on Roofs Using the Cover Method

[Case Study] Installation of Solar Mounting Structures on Roofs Using the Cover Method

Can be installed without roof material processing! Examples of using a dedicated frame compatible with the increasingly popular metal roof cover method in recent years.

We would like to introduce our achievements in the introduction of our "solar mounting systems" in residential renovations that have reached the renovation period. This product comes in two types: flat mounting systems and sloped mounting systems, with different hardware used depending on the type of roof being installed. Prior confirmation of roof material specifications, layout diagrams, and your address is essential for selecting the mounting system and calculating components. It is composed of support components and rack components, designed to meet the revised building standards with anti-corrosion specifications, implementing effective rust prevention measures. Furthermore, to securely grip and fix the roofing material, we have adopted a hole-less construction method that does not use screws. 【Case Overview】 ■ Roofing materials mainly used for cover construction: metal standing seam roofs, stone-coated steel roofs, etc. ■ Common features: Can be installed without processing the roofing material, suitable for areas with strong winds and heavy snowfall, easy-to-install support components. *For more details, please download the PDF or feel free to contact us.
