If you’ve been shopping for a high-speed line lately, you’ve probably seen the term speed 70m/min drywall roll forming machine tossed around in brochures. On paper, it sounds clean, almost too clean. On the factory floor, reality is more nuanced—coil quality, lubrication, even humidity can nudge your output. That said, the Trapezoid Roof Sheet Roll Forming Machine from YingYee is one of those “mature tech” lines that consistently gets close in real-world production, which is what matters.
Because time is money. For drywall profiles and trapezoid roof sheets, pushing line speed without wrecking tolerances is the game. Many customers say they can hold ±0.5 mm length tolerance at “around” 65–70 m/min, assuming decent coil. To be honest, the chain drive and wall-panel structure here are old-school choices—but they’re reliable, easy to maintain, and surprisingly forgiving when operators are still learning the ropes.
| Model | Trapezoid Roof Sheet Roll Forming Machine |
| Line Speed | Up to ≈70 m/min (real-world use may vary by profile/material) |
| Material | GI/GL (ASTM A653, EN 10346), PPGI, Alu-Zn; 0.3–0.8 mm typical |
| Drive / Frame | Chain drive; wall-panel structure; mature technology |
| Forming Stations | ≈18–24 (profile-dependent) |
| Roller / Shaft | GCr15, quenched & chrome plated; Ø70 mm shaft (typ.) |
| Cutting | Hydraulic post-cut; H13/D2 blades |
| Control | PLC (Siemens/Delta), encoder length control |
| Power | 380V, 50Hz, 3Ph (customizable) |
Decoiler → Guide/Leveler → Roll Forming → Servo Length Measurement → Hydraulic Cutting → Run-out Table → Stacking → Final Check. Methods: oiling/lube as needed, periodic chain tensioning, and roller alignment checks. Testing: ASTM A568/EN 10143 dimensional checks, camber/bow measurement, burr height after cut, and a 2-hour sustained run at “near” top speed. Typical test data: length tolerance ±0.5 mm, width ±0.2–0.3 mm, burr ≤0.15 mm, at 0.5 mm GI.
Profile tooling swaps, servo flying-cut upgrade, auto stacker, 5T–10T decoiler with coil car, and safety pack per IEC 60204-1. Service life is typically 10–15 years with scheduled maintenance—chains, bearings, and blades are consumables. YingYee’s team in Shijiazhuang (Room B1106, Zhongliang Plaza, No.345 Youyi North Street, Xinhua District, Hebei) handles onsite commissioning; many customers say the operator training is refreshingly practical.
| Vendor | Speed | Certs | Lead Time | Warranty | Notes |
|---|---|---|---|---|---|
| YingYee | ≈70 m/min | ISO 9001, CE | 30–60 days | 12–18 months | Chain drive, mature tech, easy spares |
| Vendor A | 60–80 m/min | CE | 60–90 days | 12 months | Higher price, servo flying-cut standard |
| Vendor B | ≈65 m/min | ISO 9001 | 45–75 days | 12 months | Economy option; fewer automation features |
Compliance-wise, look for CE (Machinery Directive 2006/42/EC), electrical per IEC 60204-1, and materials aligned to ASTM A653 or EN 10346. It seems basic, but those labels save headaches during audits. If your scope includes drywall profiles later, a speed 70m/min drywall roll forming machine-capable control and encoder is already the right foundation.
“Installed in three days, hit 68 m/min on day one. We dialed back to 64 for comfort—tolerances stayed tight.” Another buyer told me, “Spare chains and blades are cheap. That’s underrated.”
