A controlled and optimised supply chain

Quality, reliability and precision guide every stage of processing

The combination of technological innovation and in-house expertise allows us to promptly respond to the demands of an increasingly-demanding and international market.

1 coil-cutting line

Longitudinal cutting of coils to obtain customised product, ready for roll-forming.

3 roll-forming lines

Forming the strips into tubes via roll-forming, with high-frequency welding to produce a longitudinal weld seam.

1 hot-dip galvanising line

Hot-dip galvanised pipes with a diameter from 21.3 mm to 219.1 mm and length from 4,000 mm to 7,170 mm.

3 painting lines

2 with epoxy powder and 1 with water. Automated painting of tubes from 21.3 mm to 219.1 mm in diameter and 4,700 mm to 7,000 mm in length.

2 grooving lines

Pipes for fire, sprinkler and gas and water distribution systems grooved to Victaulic standards.

1 threading line

Threading systems for diameters between 21.3 mm and 114.3 mm and lengths between 1,800 mm and 7,200 mm.

2 cutting lines

Cutting of lengths shorter than standard 6,000 mm, with reduced tolerances that can be customised according to specific customer requirements.

Production cycle

From the raw material to the finished product

Acciatubi’s production cycle is based on leading-edge roll-forming and welding lines that transform hot-rolled coils, selected from the best international and certified producers.

Finishes and workmanship

Customised finishes – technology, flexibility and services to order

Dedicated facilities allow Acciaitubi to offer a broad range of machining operations, guaranteeing maximum versatility and timeliness in deliveries. All finishes can be realised according to customer requirements.

Painting

We operate with two dedicated lines for epoxy painting and a specific line for water-based painting, guaranteeing high standards of uniformity, resistance and aesthetic quality.

Hot dip galvanization

Hot-dip galvanising provides effective and long-lasting protection against corrosion, making the tubes and pipes ideal for use in outdoor environments and harsh conditions.

Aesthetic and functional solutions for technical applications

  • Threading: Precise machining for ready-to-install tubes and pipes
  • Grooving: Ready-made pipes for firefighting, sprinkler and fluid distribution systems
  • Precision cutting to size: Processing to specification to optimise time and costs on-site
  • Marking and punching: Traceability and customisation to support quality
