Sandwich Panels – Lightweight Construction, Precision, and Large Formats from Switzerland

Coratec AG develops and manufactures custom-made sandwich panels and composite panels—ranging from near-standard solutions to fully customized lightweight components. Our strength: maximum flexibility combined with cost-effective, process-oriented manufacturing in Switzerland.

Make-to-Order

We manufacture exclusively on a make-to-order basis—from project-based batch sizes to full-scale production. The starting point is either a configured base product or a completely new solution that we develop together with you. We can also manufacture products exactly according to your specifications.

Our Strengths

High flexibility

for projects and series

Efficient Production

thanks to optimized processes

Hydraulic Continuous-Action Presses

For powerful clamping force and perfect surfaces

Reliable Bonding

of multi-shift systems

3K PUR Adhesive

regardless of temperature or humidity

In-house-developed core

for exceptional surface quality

Extensive experience

with aluminum (History of Alusuisse)

Large Formats

up to 3 × 10.3 m, thickness – 100 mm

CNC Machining

up to 3 × 8 m

Our Options

We supply sandwich panels:

  • raw, for further processing

  • Processing: CNC milling, drilling, inlays, edge sealing

  • Ready for installation according to specifications

  • including assembly of subassemblies

This saves time and reduces installation effort, and prevents misalignment errors.

Aluminum – Our Core Competence

Our particular strength lies in the field of aluminum surfaces. We offer:

  • Wide range of aluminum coils in stock (1 mm / 1.4 mm / 1.5 mm)

  • optimally coordinated machinery

  • Large formats up to 2,610 × 10,300 mm or even wider with extensions

  • A strong network for special requests

Result: high-quality surfaces in large formats.

FRP – durable, versatile, readily available

We process glass-fiber-reinforced plastics in various forms:

  • Materials in stock

  • Customizations (color, texture, properties) for areas of 300 m² or more

Ideal for heavy-duty applications, impact-resistant or corrosion-resistant solutions

Special Fiber-Reinforced Plastics

Our heatable presses enable the production of high-strength structures using fiber-reinforced plastics:

  • Epoxy Resin Matrix

  • Glass or aramid fibers

  • Variable material thickness

  • Optimized Fire Performance (IMO)

  • in combination with aramid or aluminum honeycomb structures and PET foams

This technology is suitable for particularly demanding technical applications.pt

We select core materials based on specific requirements:

  • Surface Finish

  • Compressive Strength

  • thermal insulation

  • Temperature Resistance

Multi-layer structures are possible. 

Inserts serve as:

  • Mounting points

  • Reinforcements

  • Cable channels, locking mechanisms, etc.

  • Mounting Interfaces

This allows us to tailor each component precisely to the specific requirements.

Our sandwich panels are used in the following applications, among others:

  • Vehicle Construction: Side Panels, Roofs, Floors, Hatches, End Panels

  • Defense and Industrial Containers

  • Cabins and Gondolas (Cable Cars, Ferris Wheels)

  • Canopies, Awnings, Shelters

  • Partition Walls, Bathrooms

  • Platforms, intermediate floors, slip-resistant floors

  • Ventilation Ducts for Rail Applications

  • Door panels for doors and gates

  • Formwork Components and Transport Pads
