Automatic U Shape Channel Roll Forming Machine Standard

Automatic U Shape Channel Roll Forming Machine

A cold roll forming machine that produces U shape channel sections from galvanized steel coil, with hydraulic cutting and PLC control on one line.

• Production capacity about 20 m/min.
• Max. working width 500 mm (19.69 in).
• 12 roller stations as a standard set, Cr12 forming rollers, adjustable to your requirement.
• Hydraulic decoiler and hydraulic cutting system.
• PLC control with a 7.5 kW (10.06 hp) drive on a 380 V, 50 Hz, 3 phase supply.
• Easy to operate, built for construction building material production.

Product Overview

This line cold forms U shaped channel sections. Galvanized steel coil is carried on a hydraulic decoiler, guided into the roller train, progressively formed by 12 roller stations and cut to length by a hydraulic cutter, all controlled by one PLC cabinet. The section that comes off the line is a cold formed U profile with parallel flanges, used as a light structural member.

The machine is aimed at producers of construction building material: steel structure fabricators, shelving and racking manufacturers, and workshops that need a continuous supply of U section purlin or strut channel in house rather than buying it in. Roller station count, machine colour and the profile drawing can be adapted, and the section range on the supplier pattern drawing runs from ПН100 to ПН300.

Key Features

High Efficiency

The line produces up to about 20 metres per minute, so a continuous run of U sections can be cut to length without stopping the forming process.

Hydraulic Decoiler And Hydraulic Cutting

The coil is carried on a hydraulic decoiler and the finished section is cut by a hydraulic cutting system on the line, so no separate press or saw operation is needed for the cut.

Cr12 Forming Rollers On 12 Stations

The forming rollers are made in Cr12 and run on 12 roller stations as the standard arrangement, with the station count adjustable to your requirement. That combination holds the U section accurate over a long production run.

PLC Control And Easy Operation

An imported brand PLC runs the machine from a single cabinet, with easy to operate controls for quick setup and use. The drive is 7.5 kW (10.06 hp) on a 380 V, 50 Hz, 3 phase supply.

Built For Continuous Production

The base is a heavy welded bed with the station housings bolted along it and the roller train running the full length, arranged for long lasting durability and reliability in daily production.

Low Maintenance Cost

The machine is designed for minimal upkeep and repair, and worn parts that cannot be repaired are replaced free of charge during the warranty period, with technical support available for the life of the equipment.

Precise Profile Forming

The station sequence is set up to hold the U section shape repeatedly, so each cut length matches the previous one. The section designations covered by the pattern drawing are listed further down this page with their heights, widths and thicknesses.

U Section Profile Range

The section drawing below shows the U profile geometry: H is the section height, B is the flange width and t is the sheet thickness. The designations and thickness combinations listed under the drawing are the ones covered by the supplier pattern drawing.

Designation	H (mm)	B (mm)	Thickness t (mm)
ПН100	100	50	1.5 / 2.0 / 2.5 / 3.0
ПН150	150	60	1.5 / 2.0 / 2.5 / 3.0
ПН200	200	70	1.5 / 2.0 / 2.5 / 3.0
ПН250	250	80	1.5 / 2.0 / 2.5 / 3.0 / 3.5
ПН300	300	80	1.5 / 2.0 / 2.5 / 3.0 / 3.5

Other section sizes can be produced when the profile drawing is supplied, and the roller station count is adjusted to suit the section being formed.

Finished Section

The finished section leaves the line as a galvanized U channel with parallel flanges and folded lips along the flange edges, cut to the required length. It is used as a light structural member and as a support rail.

Applications

The U sections this machine produces are used as structural and supporting material in several fields:

• Construction and steel structures: stair treads, window frames and beam supports in buildings.
• Mine support: U shaped steel sections used for roadway support, where processing accuracy and output rate affect project quality and cost.
• Warehousing and logistics: continuous production of columns and guide rails for shelf manufacturing.

The line is also suited to general metal fabrication work where a repeatable cold formed U profile has to be produced in volume.

Packing And Supply Scope

• Supply scope: 1 set, sold as a single item.
• Lead time: usually two to three months.
• Customization ability: minor, drawing-based, sample-based and full customization.
• Machine colour is produced to customer requirement.

FAQ

What does this machine produce?

U shape purlin and strut channel sections, cold formed from galvanized steel coil and cut to length on the same line.

Which section sizes are covered?

The pattern drawing covers ПН100, ПН150, ПН200, ПН250 and ПН300, with section heights of 100 mm to 300 mm, flange widths of 50 mm to 80 mm and sheet thicknesses from 1.5 mm to 3.5 mm. Other sizes can be produced from a supplied profile drawing.

How many roller stations and what is the roller material?

12 roller stations as the standard arrangement, adjustable as your requirement, with Cr12 forming rollers.

How is the coil loaded and the section cut?

A hydraulic decoiler carries the coil at the entry end, and a hydraulic cutting system shears the formed section to length at the discharge end.
