Industrial high-efficiency cold roll forming production line engineered for North American standard 36" (914mm) and international 1048mm effective cover width agricultural AG panels and trapezoidal roofing/wall sheets. Features a heavy 400mm H-beam chassis, 45# forged steel chrome-plated rollers, high-speed Cr12MoV hydraulic profile shear, and Siemens/Delta PLC automation.
The Trapezoidal Roof Tile Roll Forming Machine is engineered for metal building manufacturers, agricultural shed builders, regional roofing contractors, and steel fabrication centers. The 36" AG panel profile (and international C18 trapezoidal sheet) represents the most versatile and cost-effective metal building envelope profile globally.
Accommodating prepainted galvanized steel (PPGI), galvalume (PPGL), and galvanized coils with coil infeed widths of 1200-1250mm and material thicknesses from 0.4mm to 0.8mm. The formed panel delivers 36" (914mm) or 1048mm effective coverage width with weather-resistant siphon grooves along the side overlap, guaranteeing 100% watertight roof integrity.

5: Machine Line Exit View Looking Toward Infeed in Factory Workshop
Trapezoidal AG panels represent the most widely installed building envelope panels worldwide:
Turnkey supply scope includes 5-ton manual decoiler (hydraulic decoiler optional), automatic roll forming main machine on 400mm H-beam frame with protective covers, Cr12MoV hydraulic profile cut-off station, standalone hydraulic pump station, Siemens PLC touchscreen console, and finished panel runout tables.
All precision chrome rollers and shafts are coated with anti-corrosion protective grease. The entire machine chassis is securely anchored inside a 40ft HQ shipping container using steel wire cables and timber chocks. The electrical control console and hydraulic station are hermetically wrapped in waterproof film and crated in export plywood cases.
Manufactured in compliance with ISO9001 quality management benchmarks, Bureau Veritas (BV), and STV standards. The production line holds official CE compliance certification under Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.
Q1: What is the difference between 36" AG panel and other trapezoidal profiles?
A: The 36" AG panel features 5 major ribs spaced at 9" on center with 3/4" rib height, offering an ideal balance of structural strength, ease of screw installation, and coverage economy.
Q2: What is the production speed of this machine?
A: The continuous rolling line runs at 15 to 20 m/min, enabling fast turnaround of commercial and residential roofing orders.
Q3: What thickness range of coil stock can be formed?
A: The line easily processes prepainted steel (PPGI), galvalume (PPGL), and galvanized coils from 0.4mm to 0.8mm.
Q4: Can the machine voltage match our local electrical system?
A: Yes. Motors, hydraulic systems, and PLC control modules can be configured for 220V, 380V, 415V, or 440V (50/60Hz, 3-Phase) to match your local factory power standard.
Q5: What warranty and test documentation are provided?
A: We provide over 5 years warranty, factory outgoing test video, formal inspection reports, and official CE compliance certificates prior to shipment.
