Production line and factory setup overview
A small/medium roll-forming and fabrication line producing one engineered galvanized or Zn-Al-Mg steel solar strut/rail family through coil receiving, decoiling and leveling, servo punching, multi-stand roll forming, flying cut, connector and base-plate fabrication, deburring, coating repair, dimensional gauging, sample-array assembly, structural verification, kit packing and traceability.
Recommended lowest-entry line configuration Launch one 41 x 41 mm class slotted steel strut family using 1.5-2.0 mm certified galvanized or Zn-Al-Mg coil, subject to an engineer-designed rooftop or ground-mount system. Screen a 3 t decoiler, leveler, servo punch, 16-20 stand former, 14-20 m/min cut system, connector tools and assembly/load-test fixtures. Aluminum extrusion is a separate plant.
Production process and implementation sequence
- System engineering and coil release
- Decoiling and precision leveling
- Servo slot and connection punching
- Multi-stand strut roll forming
- Flying length cut and deburring
- Connector/base fabrication and coating repair
- Representative array assembly and structural checks
- Kit counting, labels and traceable packing
Products, capacity and market fit
- Afghanistan solar projects need reliable local rails, posts and replacement components.
- Local cut lengths reduce freight and project delays.
- One engineered family controls punching, connectors and inventory.
- Wind uplift, corrosion, roof interface and galvanic compatibility are safety-critical.
- Slotted solar mounting strut - Section, BMT, grade, coating, slot, length and allowable design actions - Ground and rooftop solar integrators
- Matched mounting kit - Rails/struts, splice, clamp, base, fasteners, isolation and project bill of materials - Engineer-approved solar projects
