46mm Mini rail for facade solar mounting system​ ERK-TRB-D40

Developed for 90° vertical trapezoidal corrugated metal curtain walls, this system is suitable for facade PV projects on steelstructure workshops, warehouses, industrial office buildings and cultural-creative exhibition halls. Breaking the traditional limitation that PV systems are only deployed on rooftops, it seamlessly integrates PV modules into building facades to fully tap the value of building vertical space. Featuring an innovative clamp-free slotted architecture that eliminates conventional clamp-based fastening, PV modules clip directly into rail slots for positioning. It greatly simplifies high-altitude assembly work. With minimal exposed hardware, it balances structural safety, building-code compliance, construction efficiency and facade visual performance.
