Heavy-Duty Solar Support Roll Forming Machine | PV C Channel Line for Solar Farms and Carports – PUTAI Tianjin, China

PUTAI Heavy-Duty Solar Support Roll Forming Machine – Built for Solar Farm and Carport Structures

Large solar projects need a lot of steel, delivered on time and to exact dimensions. The PUTAI heavy-duty solar support roll forming machine lets racking manufacturers and solar EPC suppliers produce their own C channel supports from 2–3.5 mm galvanized steel, instead of relying on outside profile suppliers. Punching, forming and cutting happen in one continuous line, so each support comes off the machine ready for galvanizing or direct assembly on site.

The Problem It Solves

• Solar farms and carports use thousands of support members per project, and supply delays can hold up installation
• Buying profiles from outside suppliers adds cost, minimum orders and long lead times
• Every racking design uses different sizes and hole patterns, which standard stock rarely matches
• Thick 2–3.5 mm steel needs a rigid machine, or profiles twist and holes drift out of position

How PUTAI Solves It

• In-house production: Make supports as projects need them, in the quantities you need
• Custom tooling: Profiles and punching are built to your own racking design
• Heavy-duty frame: 90 mm forged 40Cr shafts and 18 forming stations keep thick steel under control
• One-pass processing: Holes are punched, the profile is formed and each piece is cut to length without stopping the line
• Accuracy you can build with: ±1.5 mm tolerance so members line up on site

Built to Handle Thick Steel

• Shafts: 90 mm diameter in 40Cr steel, far heavier than the 50 mm shafts used on light-gauge machines
• Drive: Gearbox with universal joints, delivering steady torque to every station
• Rollers: Forged Cr12 (D3) tool steel for high wear resistance over long production runs
• Roller stands: Archway frames with graduated adjusting nuts for precise, repeatable alignment
• Hydraulics: National standard cylinders and pumps, so spare parts can be found almost anywhere

From Coil to Finished Support

• Uncoil and straighten: The coil is fed in and straightening rolls remove curvature and stress
• Guide: The strip is centred before it reaches the tooling
• Punch: Mounting holes and slots are punched to your pattern
• Form: 18 stations shape the strip into the finished C channel
• Cut: The servo tracking cutter measures each piece by encoder or punched-hole detection and cuts on the move

Buyer Questions

• Why produce solar supports in-house? It removes supplier lead times and minimum orders, lets you match your own racking design, and lowers cost per metre on large projects.
• Can it handle 3 mm steel reliably? Yes. It forms 2–3.5 mm galvanized steel, with 90 mm shafts and a gearbox drive designed for heavy material.
• Will the holes line up on site? Punching is done in line and length is controlled by the servo tracking cutter, holding ±1.5 mm tolerance.
• Can the tooling match my racking design? Yes. Profile and punching tooling are built to your drawings.
• What output can I expect? Up to 20 m/min, depending on thickness and punching pattern.
• What should I send for a quotation? Your C channel drawing, hole pattern, thickness, length range, expected annual volume, and local voltage and frequency.
