JX Roll Forming provides Unistrut Seismic Bracing Channel Forming Solutions. The overview below covers profiles, specifications and selection logic.
A seismic bracing roll forming machine produces the strut channel used in seismic bracing assemblies — the 41-series sections that carry sway braces, pipe restraints and cable tray supports. This line covers 41×21 to 41×82 mm in 1.5–3.0 mm galvanized, PPGI or carbon steel, through 30 forming stations with a 55 kW main motor at 0–30 m/min. Delivery is 60 days.
Station count. This line runs 30 forming stations against 22 on the standard solar strut line, because seismic bracing sections carry additional return legs, stiffening details and hole patterns that have to be formed without cracking the coating. More stations means each bend is shallower, which keeps the galvanized layer intact and holds the section square after forming.
The main motor is 55 kW, sized for the 3.0 mm top of the thickness range rather than 2.5 mm.
The full 41-series range: 41×21, 41×41, 41×52, 41×62, 41×72 and 41×82 mm, in thickness from 1.5 mm to 3.0 mm. Hole patterns are punched to your drawing, including the slotted and elongated holes used in brace connections, so the section comes off the line ready for assembly rather than being drilled afterwards.

An engineer can travel to your factory for installation and commissioning. The line carries service for its working life. More than 1500 strut channel lines have been built and shipped to customers in China and overseas.
Q: Which sizes can one machine produce?
A: 41×21, 41×41, 41×52, 41×62, 41×72 and 41×82 mm, at 1.5–3.0 mm thickness. Holes are punched to your drawing.
Q: Why 30 stations?
A: The additional return legs and stiffening details in bracing sections need more gradual bending, and 30 stations keeps each pass shallow enough to protect the coating.
Q: How much floor space is needed?
A: Approximately 45,000 mm long by 30,000 mm wide, including the decoiler and the run-out table.
Q: What is the delivery time?
A: 60 days after contract confirmation.
