Product Description
Square Pipe Roll Forming Machine
The Square Pipe Roll Forming Machine is designed for the continuous production of square tubes from
galvanized steel strip using cold roll forming technology.
Unlike conventional welded tube production lines, the square pipe
profile is progressively formed and mechanically locked with a
straight seam without welding, providing a cost-effective manufacturing solution for suitable
square tube and building applications.
Different square pipe dimensions can be manufactured according to
customer requirements. The machine is designed according to the
required tube profile drawing or physical sample.
The complete production line consists of a manual decoiler, main roll forming machine, round saw cutting
system, run-out table and electrical control system. Square Pipe Roll Forming Machine

Applications
The Square Pipe Roll Forming Machine is primarily designed for
producing square pipe profiles for the building and building decoration industries.
The cold-formed square profiles can be used for applications such
as:
- Building decoration structures
- Construction profiles
- Square tube components
- Light structural applications
- Customized building profile systems

Customized Square Pipe Production
The production line can be manufactured according to the customer's
required square pipe dimensions and profile geometry.
Important: one roll forming machine is designed for one pipe size/profile according to this Word document. Customers should provide a tube profile drawing or physical sample before machine design and quotation. Square Pipe Roll Forming
Machine
Customization can therefore be based on:
- Square pipe dimensions
- Profile geometry
- Customer drawing
- Physical sample
- Production requirements
- Electrical configuration
Machine Configuration
The standard production line includes:
1. Manual Decoiler
Supports galvanized steel coils up to 1,000 kg.
2. Roll Forming Machine
17 forming stations progressively form the galvanized steel strip
into the required square pipe profile.
3. Straight-Seam Forming System
Forms and locks the longitudinal seam without conventional welding.
4. Round Saw Cutting System
Cuts the finished square pipe to the required production length.
5. Run-out Table
4,000 mm long discharge table for finished products.
6. Electrical Control System
Controls the operation of the production line.
Why Choose This Machine?
No Welding Required
The square pipe is manufactured using cold roll forming and
straight-seam locking technology, eliminating the welding process
for this particular profile design.
Lower Production-Line Investment
The original document specifically positions this system as a
lower-cost solution compared with a conventional pipe welding line.

square pipe production.
Customized Profile Engineering
The machine can be designed according to the customer's profile
drawing or physical sample.
Integrated Production Process
Decoiling, roll forming, seam forming, cutting and discharge are
integrated into one production line.
FAQ
Q1: What material can the machine process?
The standard configuration is designed for GI steel / galvanized steel strip.
Q2: What is the standard material thickness?
The Word specification gives a standard material thickness of 0.4 mm. Square Pipe Roll Forming Machine
Q3: Does the square pipe need welding?
No. The profile uses cold roll forming and straight-seam locking technology without
welding.
Q4: Can one machine produce different square pipe sizes?
According to the current machine specification, one machine is designed for one pipe size/profile. If you need another profile, please send us the drawing so we can
evaluate the required machine configuration. Square Pipe Roll
