YX25.4-520 Snap-Lok Standing Seam Roll Forming Machine
A dedicated snap-lok standing seam roll forming machine built for concealed fix metal roofing production. The line runs 0.5–0.8 mm pre-painted steel, galvanized steel and aluminium-zinc coil at 625 mm input width and delivers a snap-lok standing seam panel with a 25.4 mm seam height and 520 mm effective cover width. Hydraulic pre-punching and pre-notching let you punch fastener holes and notches in-line, so panels reach the roof ready to install without secondary machining.
Machine Configuration
- Hydraulic decoiler with coil car
- Hydraulic pre-punching device
- Hydraulic pre-notching device
- 23-station roll forming main machine
- Hydraulic shear and pneumatic edge bending device
- PLC control system with touch screen
- Finished product rack

Key Features
- In-line hydraulic pre-punching and pre-notching — fastener holes and end notches are produced during forming
- External hydraulic station — the 4.0 KW oil pump unit is mounted outside the machine frame, so oil level, pressure gauge and valve manifold stay visible and daily maintenance is quick.
- 23 CNC-machined forming stations — 45# steel rollers, fine turned and hard chrome plated, mounted on Φ75 mm shafts for stable seam geometry over long production runs.
- 11 KW inverter drive — variable frequency control keeps line speed at 15–20 m/min and adapts to different coil thickness.
- Cr12Mov heat-treated shear — hydraulic cutting with cut-to-length tolerance within ±1.0 mm.
- Pneumatic edge bending device — bends the seam edge in one pass after cutting, ready for snap-lok installation.
- Hydraulic decoiler with coil car — coil loading and positioning handled by the travelling car, reducing crane time on site.
Working Flow
Coil loading by hydraulic car → hydraulic decoiler → feeding → hydraulic pre-punching → hydraulic pre-notching → 23-station roll forming → hydraulic shear → pneumatic edge bending → finished product rack.
Application
Suited to metal roofing contractors, roofing panel producers and steel structure suppliers making concealed fix standing seam roofs for warehouses, factories, commercial buildings, villas and airports. Panels are produced from PPGI, PPGL, galvanized and aluminium-zinc coil.
