Product Description

Duct Support Slotted C Channel Roll Forming Machine

The JACK-AIVA Duct Support Slotted C Channel Roll Forming Machine produces perforated C-shaped support channels from galvanized steel strip. The finished channels are used in HVAC duct suspension systems, pipe supports, cable tray supports and mechanical service installations.

Also known as a Slotted Strut Channel Roll Forming Machine for HVAC Duct Supports, the line combines decoiling, servo-controlled hydraulic punching, roll forming and cutting. Mounting slots are punched into the strip before it passes through the forming stations to create the required channel cross-section.

The specified configuration processes 1.2–1.8 mm soft-quality, annealed galvanized steel, using 18 forming stations and a 7.5 kW main motor. Cr12MoV forming rollers are hardened to HRC 60–62, and the forming speed is adjustable within 0–10 m/min.

Channel dimensions, slot patterns and finished lengths can be specified according to the customer's drawings. Hydraulic cutting or saw cutting can be selected to suit the agreed production requirements.

Production Process

Decoiling → Strip Loop → Servo-Controlled Hydraulic Punching → Strip Loop → Roll Forming → Cutting → Run-Out Table

The decoiler supplies steel strip to the punching section. After the required mounting slots are punched, the strip enters the roll forming machine, where successive roller stations form the C-shaped section. The cutting unit separates the formed channel into the required lengths, and the run-out table supports the finished products.

The strip loops provide material buffering between the processing sections.

Key Features

Technical Parameters

The stated speed refers to roll forming speed. Actual finished-channel output depends on the punching pattern, channel length and cutting cycle.

Servo-Controlled Hydraulic Punching

The production line includes a servo-controlled hydraulic punching unit to produce mounting slots before roll forming.

The punching tooling is selected according to the required slot shape, dimensions and pitch. Integrating this operation into the line allows the mounting features to be produced during channel manufacturing, reducing the need for separate drilling or punching afterward.

For quotation and tooling design, customers should provide a drawing showing the slot layout, edge distances and any special hole requirements.

Slotted C Channels for HVAC Duct Supports

Slotted C channels can be used as crossmembers in trapeze supports for rectangular ventilation ducts. When assembled with suitable threaded rods, nuts and connecting hardware, they provide a support arrangement beneath the duct.

The slots allow fixing positions to be adjusted along the channel during installation. This makes the profile useful for coordinating duct supports with site dimensions and service layouts.

In a suitable external support arrangement, the channel supports the duct without requiring the supporting fasteners to penetrate the duct wall.

Channel size, material thickness, support spacing and connecting hardware must be selected according to the installation's load requirements.

Machine Configuration

Decoiler

Holds the steel coil and supplies strip to the production line.

Servo-Controlled Hydraulic Punching Unit

Produces the specified mounting holes or slots before the strip enters the forming section.

Strip Loop Sections

Provide material buffering between decoiling, punching and roll forming.

Main Roll Forming Machine

Uses 18 forming stations to progressively shape the punched strip into the required C-channel profile. The machine features a portal-type A3 steel frame, Ø42 mm forming shafts and hardened Cr12MoV rollers.

Cutting Unit

Cuts the formed channel to the required length. Hydraulic cutting or saw cutting is selected according to the confirmed machine configuration.

Run-Out Table

Supports the finished channels as they leave the cutting section.

Applications

The machine produces slotted support channels for:

• Rectangular HVAC duct suspension.
• Trapeze supports for building services.
• Pipe and conduit support assemblies.
• Cable tray support structures.
• Mechanical equipment mounting frames.
• Customized metal framing and fastening systems.

The finished channel design should match the load and installation requirements of each application.

Why Choose This Machine?

Punching and Forming in One Line

The production sequence combines slot punching, channel forming and cutting, reducing transfers between separate processing machines.

Defined Material Range

The specified configuration is designed for 1.2–1.8 mm soft-quality galvanized steel used in duct support channel production.

18-Station Forming System

Successive forming stages progressively develop the channel section and return lips according to the approved profile drawing.

Hardened Cr12MoV Rollers

The forming rollers are heat-treated to HRC 60–62 for wear resistance during repeated production.

Choice of Cutting Method

Hydraulic cutting and saw cutting options allow the cutting arrangement to be selected for the required profile and production conditions.

Customized Support Profiles

Channel cross-sections, mounting slots and finished lengths can be developed around the customer's support system.

Optional Configuration for Thicker Channels

For projects requiring 2.0–2.5 mm steel, JACK-AIVA can provide a separately specified channel production solution.

This thicker-material option may be considered for applications such as solar mounting and other support structures, subject to the approved profile design and material requirements.

The forming, punching and cutting configuration must be reviewed for the thicker material. The 1.2–1.8 mm machine specification above should not be treated as the confirmed specification for the thicker-channel version.

Information Required for Quotation

To prepare a suitable machine proposal, please provide:

• Channel cross-section drawing with dimensions and tolerances.
• Material grade, thickness range and available coil width.
• Slot shape, slot dimensions, pitch and hole layout.
• Required finished channel lengths.
• Target production capacity.
• Preferred cutting method.
• Local electrical supply.
• Available workshop space and any special production requirements.

Send your channel drawing or sample details to JACK-AIVA for a suitable roll forming solution.

FAQ

What does this machine produce?

It produces slotted C-shaped steel channels used in HVAC duct supports, pipe supports, cable tray supports and related mounting systems. The finished cross-section is defined by the approved profile drawing.

What material thickness can it process?

The specified configuration processes 1.2–1.8 mm soft-quality, annealed galvanized steel.

Does the machine include slot punching?

Yes. The line includes servo-controlled hydraulic punching before roll forming. The punching tooling is prepared according to the required hole or slot pattern.

What is the forming speed?

The specified forming speed is 0–10 m/min. Actual finished-product output depends on the punching cycle, slot pattern, cutting method and channel length.

Which cutting methods are available?

Hydraulic cutting or saw cutting can be selected. The supplied cutting arrangement is confirmed in the machine proposal.

Can the channel dimensions and slot pattern be customized?

Yes. The profile section, slot dimensions, hole pitch and finished lengths can be specified according to customer drawings. The required tooling and machine configuration are determined during technical review.

Can this machine process 2.0–2.5 mm material?

A separate configuration can be supplied for 2.0–2.5 mm channels. This capability is subject to technical review and is not included in the stated 1.2–1.8 mm configuration.

Does the machine produce complete duct hanger assemblies?

The line produces the slotted channel component. Threaded rods, nuts, clamps and other assembly hardware are separate components of the finished duct support system.
