Garage Door Strut Roll Forming Machine

Garage Door Strut Roll Forming Machine 

その Garage Door Strut Roll Forming Machine is a fully automatic production line designed specifically for manufacturing structural reinforcement struts used in sectional garage doors. These struts increase door rigidity, prevent panel deformation, and improve overall operational stability. The machine delivers high precision, strong rigidity, and continuous high-speed output, making it the ideal solution for garage door manufacturers.

1. Application

This equipment is used to produce U-shaped and Hat-shaped garage door struts from galvanized steel coils. Common applications include:

• Residential and commercial garage door panels

• Sectional door reinforcement

• Industrial overhead door support

• Customized door stiffening bars

Strut thickness options typically range from 14–24 gauge (1.0–3.0 mm).

2. Machine Composition

The complete production line includes:

1. Decoiler / Uncoiler

   • Manual or hydraulic options

   • Supports steel coils up to 3–5 tons

   • Smooth and stable feeding to prevent material scratching

2. Leveling & Feeding System

   • Straightens coil material

   • Ensures consistent feeding accuracy

3. Servo Punching System (Optional)

   • Pre-punching or post-punching patterns available

   • Custom hole shapes and distances

   • High-speed punching with minimal deformation

4. Roll Forming Section

   • 10–18 forming stations depending on profile type

   • High-grade steel rollers with hard chrome plating

   • Ensures accurate and smooth strut shape

5. Cutting System

   • Hydraulic or servo tracking cutting

   • Burr-free, precise length cutting

   • Auto length control via PLC

6. PLC Control Cabinet

   • Siemens/Delta control system

   • Touch screen operation

   • Adjustable speed, batch setting, emergency stop, fault alarm

7. 振れテーブル

   • Collects finished struts safely

   • Can be chosen as manual or automatic stacking

7. Frequently Asked Questions (FAQ)

Garage door strut braces (also called garage door struts, reinforcement struts, or stiffener bars) are long, U-shaped or hat-shaped steel channels installed horizontally on sectional garage door panels.
They are usually made from galvanized steel to provide strength and corrosion resistance.

A strut brace reinforces each panel of the garage door, helping it stay rigid and stable during opening, closing, and daily operation.

1. Reinforce and Strengthen Door Panels

Garage door panels can flex or bend, especially large or thin panels.
Strut braces add rigidity, preventing the door from twisting or bowing.

2. Support Automatic Garage Door Openers

If the door is operated by a motor, the opener pushes/pulls the top section.
A strut brace gives the top panel enough strength to handle this force.

3. Increase Door Lifespan

By reducing panel stress and structural wear, strut braces help the door last longer and reduce maintenance costs.

Where Are Strut Braces Commonly Installed?

• Top section of the garage door

• Middle sections for large doors

• Every panel for high-wind-rated commercial doors

Thickness usually ranges from 14–24 gauge galvanized steel.

8. Safety Instructions

• Never place hands near the roll station during operation.

• Always disconnect power before adjusting tooling.

• Emergency stops are located at the entry and exit ends.

• Wear gloves and safety glasses when changing dies.
