Custom-built plants for PE/PP single- and double-layer coating of steel tubes in roll-forming lines.
Specialization · Interplast
Plants designed
around your needs.
Interplast specializes in the design and construction of complete plants for coating steel tubes in roll-forming lines. We build single- and double-layer PE/PP extrusion coating lines, optimized for every production and dimensional requirement.
Each plant is designed in collaboration with the customer, taking into account tube diameter, required production speed, polymer type, and final operating conditions. The result is an efficient, reliable, and long-lasting line.

Why Choose Us
From Design To delivery
Requirements Analysis
We collect all technical specifications: tube diameter, line speed, polymer type, coating thickness, and operating conditions.
Plant Design
Our engineers design every line component: extrusion head, cooling system, haul-off unit, winder, and control panels.
Construction and Assembly
The plant is built and assembled entirely in our workshop using components selected from the best European suppliers in the plastics industry.
Testing and Installation
Before shipment, every line is tested at full capacity. Our team follows the installation at the customer’s site and trains staff on operation.
Why Choose Us
THE ADVANTAGES OF AN INTERPLAST PLANT
Single- and Double-Layer PE/PP
We build single-layer and double-layer coating lines in polyethylene or polypropylene, suitable for the most demanding anti-corrosion protection standards.
Integration into Roll-Forming Lines
Our plants integrate perfectly into existing roll-forming lines, minimizing adaptation costs and production start-up times.
Advanced Automation and Control
Every line is equipped with modern control systems — PLCs, touchscreen HMIs, real-time process parameter management, and data recording.
Post-Installation Support
We offer complete operator training, an operating manual, remote technical assistance, and on-site service throughout the entire operating life of the plant.
