Solar & Renewable Energy
PV mounting racks endure year-round outdoor exposure — temperature swings, wind loads and salt spray loosen and corrode ordinary plated fasteners, shifting panel angles and cutting power output. Mixing aluminium rails with stainless or plated parts invites galvanic corrosion every time it rains, and coastal Hong Kong rooftops add typhoon-grade wind vibration and salt spray on top. JIALI supplies 304 / 316 stainless steel, hot-dip galvanised and Dacromet-coated bolts, locking nuts, washers and spring clips, with isolating gaskets for dissimilar metals and anti-loosening design advice, ASTM B117 salt-spray tested — a reliable Hong Kong supplier of solar mounting fasteners, supporting drawing-based custom and batch supply.
