What to Pay Attention to When Installing Resin Shingles?

When installing resin shingles, the spacing of rafters should be properly controlled: the main rafter should not exceed 660mm, and the secondary rafter should not exceed 750mm. Use special waterproof washers and 304 stainless steel self-tapping screws for fixation. Do not over-tighten the screws to avoid cracking the panels.预留 a gap of 4-5mm per meter for expansion and contraction. Additionally, install the shingles against the local wind direction and ensure the overlap length meets requirements to guarantee the waterproofing effect.
