Selecting Right Material For Solar Power Industry Fasteners:
Each material offers different benefits based on how you are planning on using the fastener. One should consider the material mainly based on the solar panel mounting method types. Rooftop installations are continuously exposed to various elements and therefore it is advised to use High-quality Stainless-Steel material A2-70 / SS 304 & A4-70 / SS 316.
For the installation which demands high strength and economical we recommend to used Carbon Steel Grade 8.8 with an HDG finish which lasts longer and gives good strength for both Pole-Mounted and Roof Top installations of solar panels.
