Solar Uni Strut Channel Making Machine

This machine is calibrated strictly to global unistrut specifications. All profile opening size, groove geometry and slot spacing maintain universal interchangeability. Unlike generic PV bracket profiles, the finished uni strut works directly with internationally standard solar fasteners. Installers can slide clamps and spring nuts freely along the slotted channel to adjust solar panel positions on site.

Solar uni strut needs excellent straightness and stable opening dimension to bear wind and snow load. The roll forming stations adopt multi-stage gradual rolling with built-in springback compensation. When forming thick HDG and Al-Mg-Zn steel, it effectively prevents profile twisting and opening deformation, ensuring uniform mechanical performance for outdoor PV mounting.

Equipped with servo feeding and inline punching system, it produces continuous elongated slots with tight ±0.3mm position tolerance. Uniform slot distribution is the core feature of uni strut, supporting flexible assembly. No secondary drilling is required after production, greatly saving post-processing labor for your factory.

Special polished and chrome-plated roller surface avoids scratches and zinc coating peeling during roll forming. The galvanized and alloy coating of finished uni strut remains intact, delivering long anti-corrosion lifespan in coastal areas, high humidity and open-air solar farms.

This is a dedicated unistrut production line instead of a multi-profile universal machine. The fixed tooling setup minimizes dimension fluctuation in mass production. It is perfectly suited for factories supplying standardized strut kits for large-scale solar EPC export orders.
