HOPEX-Solar Channel
The HOPEX solar channel roll forming machine rolls four channel depths from the same mill: 41×41, 41×52, 41×62 and 41×72. Each size runs from its own feeding strip width — 135, 157, 177 and 197 mm respectively — so the section profile stays true across the range.
Furthermore, the line forms galvanized strip 1.5–2.5 mm thick at 10–15 m/min. Consequently a single solar channel machine covers a full channel family instead of one fixed section.
Suited to producers who supply several channel depths and need predictable geometry on every size.
| Section | Feeding strip width | Material | Thickness |
|---|---|---|---|
| 41 × 41 | 135 mm | Galvanized steel | 1.5 – 2.5 mm |
| 41 × 52 | 157 mm | Galvanized steel | 1.5 – 2.5 mm |
| 41 × 62 | 177 mm | Galvanized steel | 1.5 – 2.5 mm |
| 41 × 72 | 197 mm | Galvanized steel | 1.5 – 2.5 mm |
All four share the same 41 mm face width, so downstream fittings and channel nuts remain interchangeable.
Channel geometry is built gradually. The mill carries 26 forming passes of Cr12 mould steel rollers, vacuum quenched to HRC 58–62, mounted on φ80 mm shafts of quenched and tempered 45# steel.
Moreover, the stands sit in a cast iron housing frame and the drive comes from two 18.5 KW K97 hard-tooth-surface reducers through a gearbox with coupling connection. A water circulation system holds tooling temperature steady, which keeps the lip and web dimensions consistent from the first metre to the last.

Each solar channel roll forming machine is wrapped, braced on a steel base and container-loaded for export delivery.
Q1. Which channel sections does the mill produce?
41×41, 41×52, 41×62 and 41×72, all sharing a 41 mm face width.
Q2. Does each section need a different strip width?
Yes — 135, 157, 177 and 197 mm respectively.
Q3. How many forming passes are used?
26 passes of Cr12 mould steel rollers, vacuum quenched to HRC 58–62.
Q4. What thickness range is supported?
1.5–2.5 mm galvanized strip, tolerance ±0.03 mm.
Q5. How is tooling temperature managed?
A water circulation system is built into the main forming machine.
Q6. What is the rated line speed?
10–15 m/min with inline punching.
