T purlin channel machine

The T purlin roll forming machine is one of the most specialized and sought-after solutions in the structural steel industry. Designed to produce T-shaped steel purlins, this machine offers accuracy, speed, and high productivity for a wide range of industrial and construction applications. In this article, we’ll take a deep dive into the full machine specifications, profile characteristics, popular markets, machine pricing, and how Machine Matcher can help you select the right equipment.

Full Machine Description

A T purlin roll forming machine is used to manufacture structural T-shaped metal profiles from galvanized steel or other coated steel coils. These profiles are used primarily in roofing and steel framing applications where central support is needed. The roll forming process uses a series of precisely machined rollers that gradually shape the metal into its final T-profile without heating or welding.

This machine is engineered for continuous, automated production with options for punching, notching, cutting, and stacking, delivering ready-to-install profiles with minimal manual handling. With various configurations available, it can be built for specific widths, heights, and thickness ranges, depending on the buyer's application needs.

Machine Specifications

Roller Materials
The rollers are typically made of high-grade GCr15 (bearing steel), hardened and polished for long life and accuracy. In some models, Cr12Mov material is used for extra wear resistance, especially in high-volume production.

Punching and Notching Units
CNC-controlled hydraulic punching and notching stations are integrated before or during roll forming, allowing for holes, slots, or other shapes as required for assembly or structural use.

Servo Motors
Servo motors are used to drive the punching and cutting stations with high precision. They ensure accurate positioning and synchronization with the PLC system to achieve perfect alignment.

Hydraulic Cutting System
T purlin machines come with a hydraulic post-cut system using Cr12 cutting blades, ensuring clean and burr-free cuts. The hydraulic unit is robust and designed for long operational life with minimal maintenance.

Frame Size
The machine base is usually made from heavy-duty H-beam steel, fully welded and stress-relieved to prevent warping. Frame sizes typically range from 300mm to 500mm width, depending on the profile.

Motors and Drive System
Equipped with branded motors (Siemens or equivalent), the drive system uses chain or gearbox transmission for powerful and stable forming performance.

PLC System
The heart of the machine is a fully integrated PLC control system (commonly Siemens, Panasonic, or Mitsubishi) with a user-friendly touchscreen HMI. It manages profile length, punching positions, speed, cutting, and automatic stacking.

Machine Speed
Standard forming speed ranges from 15–30 meters per minute. High-speed versions can reach up to 40 m/min, depending on profile complexity and extra functions.

Safety Guards and Enclosures
All moving parts are covered with safety enclosures or plexiglass covers to prevent accidents and ensure safe operation. Emergency stop systems are also included for immediate shutdown in case of issues.

Setup and Installation

Setting up a T purlin roll forming machine involves the following steps:

1. Foundation Preparation
   A level, vibration-free concrete base is required.

2. Machine Placement and Alignment
   All components (uncoiler, forming unit, hydraulic system, cutting unit) must be aligned in a straight line.

3. Electrical and Hydraulic Connections
   Proper power supply and oil filling are necessary, matching the motor and hydraulic system specs.

4. Profile Testing and Calibration
   A trial run is done using your coil material and profile drawing to calibrate the rollers, punches, and cutters.

5. Training and Commissioning
   Operators are trained on the PLC interface, profile adjustments, safety protocols, and daily maintenance.

Maintenance and Longevity

To keep your T purlin roll forming machine running at peak performance:

• Daily cleaning of rollers and guides

• Lubrication of moving parts per manufacturer schedule

• Checking alignment of punches and cutters weekly

• Replace hydraulic oil every 6–12 months

• Routine electrical system checks

With proper care, the machine can run continuously for 10–15 years with minimal downtime.
