Since 1958
We calender very thick sheets of metal, from 8 to 220mm.
Let’s think big.
For more than half a century, our vision remains unchanged: embrace change to generate value. Our expertise extends to industrial calendering, with a specific focus on processing thick sheet metal. We roll thick sheet metal with a skill and precision that reflect our experience. We follow precise rules: attention to detail, assurance of certification, and strict application of technique.
Processed steels
Sidertaglio Calandratura specializes in
the processing of various types of steel, including:
Low-alloy steel contains small percentages of chromium, molybdenum, and nickel. It withstands high temperatures, operating pressure, and corrosive environments at a lower cost than high-alloy steels. We roll it to a thickness of up to 220 mm, with certification to ASME Section VIII Div. 1 and Div. 2 for pressure vessels and AD 2000. This is the alloy required for projects in the petrochemical, oil & gas, and power generation sectors, where operating conditions preclude the use of standard carbon steel.
High-yield steel can withstand high loads for a given thickness. It allows for lighter structures without sacrificing strength, and is required where every kilogram counts. We cold-roll it up to 220 mm in accordance with EN 1090-1 EXC3 certification for load-bearing structures. This alloy is used in offshore projects, onshore wind farms, and renewable energy installations, where reducing weight while maintaining performance cuts transportation and installation costs.
Wear-resistant steel has high surface hardness, achieved through specific alloys and heat treatments. It withstands abrasion, impact and prolonged friction. We roll it up to 100mm, working Hardox grades in 400, 450 and 500 HB hardness. It is the work required for crushing plants, bulk material handling and components exposed to constant stress, where the quality of welding determines the working life of the finished part.
Boiler steel is used in the construction of pressure vessels and steam generators, where leak-tightness and resistance to high temperatures are essential requirements. We roll it to a thickness of 220 mm, with ASME Section I certification for boilers and ASME Section VIII Div. 1 and Div. 2 certification for pressure vessels. This is the kind of manufacturing sought after by the Oil & Gas, Petrochemical, and Power Generation industries, where documentation is just as important as the manufacturing process itself.
Structural steel is the foundation of load-bearing structures and heavy steel fabrication. Workable, weldable, certified: it covers most applications where structural reliability and controlled cost are both required. We roll it up to 220mm thick, with ISO 3834-2 welding qualification and CE marking under EN 1090-1 EXC3. It is the work that heavy fabricators, industrial structures and large-volume projects require from a supplier who can guarantee consistency over time.
Stainless steel resists corrosion thanks to chromium, which forms a passive layer on its surface. It is the material of choice when water, chemicals, or harsh environments make carbon steel unsuitable. We roll it on two dedicated lines: from 3 to 50 mm in the white zone without carbon contamination, and from 50 to 160 mm in the heavy-gauge section. We work with AISI 304, 316, 321, Duplex, and Superduplex, with ASME and ISO 3834-2 certification.
