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.
