CPL

Optimized strength with unlimited design freedom

CPL is the smart choice for future-proof, lightweight engineering

About
CPL

Corrugated Plate (CPL) is the registered brand name of Corrugated Plate Industry BV — offering a high-performance structural product that combines strength, flexibility, and efficiency. Developed using a patented, mould-free production process, CPL plates are manufactured in unlimited lengths and variable geometries, giving engineers and architects maximum freedom in design.

Key Features

Unlimited Length

Theoretically unlimited plate lengths with seamless integration into large-scale structures. Transportable lengths up to 18 meters.

Wide Material Range

Available in steel grades (S235JRG2, S355J2G3, Lloyd’s Grade A), aluminium, and stainless steel.

Tailored Geometry

Corrugated plates behave as 3D structures, significantly increasing resistance to vertical and horizontal loads — ideal for reducing material weight without compromising strength.

Technical Specifications
  • Thickness (tw): 1.5 – 12 mm
  • Module (N): Up to 1000 mm
  • Corrugation depth: Max. 240 mm
  • Folding angles: Standard 45°, up to 70° possible
  • Tolerances: DIN EN ISO 13920-CG, length tolerance +0 / -5 mm
Applications

CPL is widely used across engineering and construction industries where weight reduction, strength, and durability are critical:

  • Offshore structures and shipbuilding (e.g., double-hulled ships)
  • Industrial walls and floors
  • Retaining walls and silos
  • Transport panels (trains, trucks, containers)
  • Conveyor systems
  • Cranes and supporting columns
  • Hybrid concrete-steel constructions
Why choose
CPL
?

Corrugated Plate (CPL) offers an exceptional balance between strength, flexibility and efficiency. Thanks to its unique corrugated profile, CPL behaves like a three-dimensional structure, significantly increasing its resistance to both vertical and horizontal loads. This allows for the use of thinner materials without compromising on performance, reducing both weight and material costs.

The patented, mould-free production method ensures maximum design flexibility, with custom geometries, thicknesses, and folding angles tailored to the needs of your project. CPL plates are suitable for a wide variety of structural and industrial applications — from offshore walls and silos to transport panels and hybrid constructions. With unlimited length and robust technical characteristics, CPL is the smart choice for future-proof, lightweight engineering.

What are the advantages of using corrugated plates over traditional flat steel plates?

Corrugated plates offer a significantly higher strength-to-weight ratio, allowing for lighter constructions without compromising structural integrity. They also enable longer spans and reduce the need for additional reinforcements.

Can corrugated plates be customized to fit specific project requirements?

Yes. Our patented production process allows us to produce plates of unlimited length and in various dimensions, tailored to the exact needs of your construction project.

What types of projects are corrugated plates and GLP beams suitable for?

Our solutions are ideal for industrial buildings, offshore constructions, bridges, floor systems, and long-span structural applications that require both strength and material efficiency.

How is quality ensured during production and delivery?

All our products undergo rigorous quality checks throughout the production process. We comply with European standards and offer optional surface treatments, such as hot-dip galvanizing, for additional durability.

What is the maximum transport length for corrugated plates and beams?

Due to transportation regulations, the maximum transportable length is 18 meters. For longer constructions, on-site assembly or segment connection is advised.
