A cold roll forming machine with two forming station rows mounted on one bed, built to produce both AG panel and corrugated roof sheet from color coated steel coil.
This machine is built for making roofing sheet. It carries two forming layers on a single welded bed, so one machine can produce two different roofing sheet profiles: the AG panel takes 19 roller stations and the corrugated panel takes 22 roller stations. The coil runs through the decoiler and the feeding device, is formed by one of the two station rows, and is then cut to length and stacked automatically.
The double layer arrangement suits buyers who need to cover more than one roofing profile with a single machine and to keep the factory footprint down. Both layers sit on the same frame and share the drive, the cutting system, the control cabinet and the stacker, so the second profile comes without a second line.
2-In-1 Double Layer Design
Two forming station rows are mounted one above the other on one machine bed, so the line produces both an AG panel profile and a corrugated profile. The two layers run one at a time: a given batch is produced on either the AG layer or the corrugated layer, not on both at once.
Wide Applicability
The machine is set up for the requirements of producing different panels, and the roofing panel profile drawing can be customized for the profile the buyer needs.
Space And Cost Saving
One machine covers two profiles, which saves both the capital cost of a second line and the factory space it would occupy. The two layers share the bed, the drive and the auxiliary equipment.
Fully Automatic PLC Control
An imported brand PLC runs the whole machine, so batch, length and quantity can be set from the control panel and the machine then works automatically. The control cabinet uses a touch screen, aviation plugs for easy installation, and supports customized and multiple languages.
Heavy Welded Frame
The main frame is welded from 400 H high grade steel and 20 mm thick welded plate, with diagonal braces to prevent deformation and damage during lifting and shipping, plus lifting lugs for port lifting and transportation.
Hydraulic Decoiler And Feeding Device
A hydraulic decoiler carries the coil: 5 t capacity, coil inner diameter 450-550 mm and feeding width up to 1220 mm. The hydraulic cylinder expands the mandrel to fit the coil inner diameter, and the driven mandrel can run forward and reverse and uncoil with tension. The feeding device uses hand wheels on both sides to adjust the feeding width, four stainless rollers to take the material into the machine without scratching the surface, and three rows of orange plastic rollers to guide the coil in smoothly.
Forming Rollers, Shafts And Cutting System
The rollers are made of 45# steel with a hard chrome plated surface, mounted on 80 mm solid shafts, and the machine uses double chain transmission. Cutting is automatic, with two kinds of cutter on a four pillar cutting system that keeps the cut stable; the blade is Cr12 mould steel, specified to leave no scratches and no deformation. An automatic oil filler lubricates the cutter, which reduces maintenance time and cost.
Automatic Stacker And Hydraulic Station
An automatic stacker receives the sheet after cutting, stacks the sheets in order and conveys them out once a batch is finished. The hydraulic station is the updated type with low noise, a cooling fan for long service time and a thermometer that shows the oil temperature in real time.

The line is laid out along one bed, with the coil handling at the entry end and the sheet handling at the exit end:
The two profiles produced on the same machine are shown below: the trapezoidal AG panel with parallel ribs and flat pans, and the corrugated panel with a continuous wave section. Both are formed from color coated steel coil in 0.3 mm to 0.8 mm thickness and can be cut to the required length by the PLC.
The machine is used for roof sheet production: roofing panels, wall cladding panels and workshop building panels made from color coated and galvanized steel. It suits roofing sheet manufacturers and building material suppliers that need two roofing profiles in house, and it is normally installed as part of a small roofing sheet production line with the decoiler at the entry and the stacker at the exit.
What does this machine produce?
Two roofing sheet profiles from color coated steel coil: the AG panel and the corrugated panel, formed and cut to length automatically.
Can both profiles be produced at the same time?
No. The two layers are produced one at a time: a batch runs on either the AG layer or the corrugated layer. The benefit of the design is that both profiles come from one machine and one set of auxiliary equipment.
Which material and thickness can it run?
PPGI, PPGL, GI and GL coil from 0.3 mm to 0.8 mm thick, with a feeding width of 920-1250 mm.
How is the machine driven and controlled?
Double chain transmission, an imported brand PLC with touch screen, a 7.5 kW main motor and a 380 V, 50 Hz, 3 phase supply as customized.
What are the roller and cutting details?
AG panel 19 roller stations and corrugated panel 22 roller stations, all in 45# steel with a hard chrome plated surface on 80 mm solid shafts, and a Cr12 mould steel blade in a four pillar cutting system.
What warranty and service are provided?
A 3 year warranty, CE and ISO certification, free replacement parts and online technical support, with video outgoing-inspection and a machinery test report before shipment.
