Contract Plate Rolling Service

Specialized cold roll bending converting flat sheet metal into high-precision cylindrical shells, conical sections, rings, and curved profiles.

Precision Plate Rolling & Curvatures

Looking for a reliable partner for contract plate rolling? Our fabrication shop offers a specialized cold bending and forming service, designed to turn flat sheets into high-precision cylinders, cones, rings and curved profiles. With technologically advanced plate rolls and a highly experienced team, we meet the most complex requirements of the boilermaking, industrial plant and design sectors.

Plate rolling demands deep knowledge of material springback and plastic deformation. As your subcontract partner, we ensure uniform curvature and tight tolerance compliance for pressure vessels, industrial piping, and architectural elements.

Plate Rolling Advantages

Plate rolling is performed by passing the metal sheet through a series of parallel rolls (usually 3 or 4). By applying controlled, geometrically defined pressure, the rolls plastically deform the material until it takes on the desired curvature.

Entrusting your orders to our contract service gives you immediate strategic advantages:

Defect-Free Uniformity

Millimeter roll positioning avoids faceting, flat spots, or surface distortion.

Pre-Bending Optimization

Modern 4-roll machines minimize flat leading/trailing edges (pre-bending), delivering true cylinders ready for seam welding.

Precision Conical Rolling

Tilted roll kinematics create accurate truncated cones and hoppers with true convergence.

Surface Preservation

Hardened ground rolls and protective films prevent iron contamination and scratches on stainless steel or aluminum.

Technical Capacities

Our range of 3-roll and 4-roll machines handles thin precision rings up to heavy structural plates for large-diameter industrial tanks.

Applications

Our contract plate rolling service precisely meets the needs of many industries:

Boilermaking & Tanks

Pressure vessels, storage tanks, silos, and heat exchanger shells.

Ducting & Environmental

Large-diameter ducting, cyclones, stacks, and ventilation housings.

Architecture & Construction

Cladding columns, curved structural beams, and canopy framework.

Recycling & Heavy Industry

Rotary screen drums, trommels, and cylindrical machine guards.

Frequently Asked Questions (FAQ)

What special alloys can you roll?

Carbon steel, stainless steel (AISI 304/316 in isolated clean areas), aluminum, Hardox wear-resistant plates, tread plates, and perforated sheets.

How does the integrated process work from laser cutting to rolling?

CAD software calculates flat sheet development, laser cutting prepares weld bevels (chamfers), and rolls form the exact geometry ready for fit-up.

Can you deliver rolled shells tack-welded or fully seam-welded?

Yes. Our certified welding division can tack-weld or fully seam-weld rolled shells and perform re-rolling to restore 100% roundness.

What is the advantage of rolling on 4-roll machines?

The main advantage is optimized pre-bending. Compared to traditional systems, modern 4-roll machines minimize the flat section at the leading and trailing edges of the sheet. This produces geometrically perfect cylinders ready to be welded directly along the seam, eliminating costly and slow trimming operations.

Sheet Metal Bending

  • Processed Materials: Iron, aluminum, steel and a wide range of thicknesses and lengths.

  • Structural Advantage: A cleverly bent sheet metal component can replace multi-part welded assemblies, reducing production costs while yielding stronger, cleaner parts.

  • Millimeter Precision: CNC programming calculates exact bend allowances and sequences, matching drawing specifications down to the millimeter.

02

Tube Bending

  • Materials & Formats: Carbon steel, stainless steel, aluminum, copper and brass on round, square or rectangular sections.

  • Structural Integrity: CNC mandrels prevent wrinkling or flattening, keeping tube cross-sections clean and uniform.

  • Repeatability: Precision control guarantees identical parts across small batches and mass production.
