Coratec sandwich panels for processors

Processors

Our sandwich panels are used in the areas of construction, vehicle construction and industry for many different applications. We help you choose the right product for your application.

We develop and produce high-quality sandwich panels which are particularly suitable for applications in vehicle construction or as facade, wall, ceiling, floor or door elements in building construction. Our long-standing company history provides us with a lot of expertise and experience to react quickly to your demands.
We manufacture exclusively to order. Be it raw sandwich panels or ready-to-install, functional elements with customer-specific surfaces, inlays and edges. Our flexible manufacturing process allows for many possibilities.

Our customers choose us based on the following advantages:

  • Large formats: We offer large panels up to a width of 2,200 mm with perfect surface quality.

  • Special surfaces: Customized paints or chrome steel outer layers are no problem for us.

  • Inlays: They are usually used as reinforcements, cable ducts or fastening points for hinges and locks. However, more complex inlays such as heaters, cooling systems, lighting, vacuum cans, etc. can also be integrated.

  • High stability: Sandwich panels with a Corapan core are particularly rigid.

  • Durability: Our composite panels are extremely weather-resistant and robust, having proven themselves over many years.


These are our core competencies:

  • Door fillings for doors and gates
  • Soffits
  • Roofs for canopies, carports, patios, stops, etc.
  • Load-bearing floor panels for balconies
  • Partition walls
  • Vehicle construction (beverage service trailers, horse transporters, expedition vehicles, truck hatches)

Tips for the processing of sandwich panels

We have the infrastructure and excellent network of suppliers to offer you completely processed products. If you want to do partial or complete processing yourself, you will find information and tips on how to do this here.

Machining
Most machining operations are possible using the usual cutting tools. Carbide-tipped blades have a much longer service life. With CORAPAN® GFK, slight edge fractures are possible on glass-fiber reinforced plastic laminates. For decorative cuts, diamond-tipped cutting tools should be used.
Almost all common workshop machines and many hand tools are very well suited for sawing, milling and drilling the composite elements.

Screw connections in the top layer
Grooved or screwed connections and fastenings provide the same strength as those in other metal sheets of the same thickness. Adhesion can be considerably improved by additional bonding of the joining parts.

Inserting profiles and edges
The panels can be fitted with aluminum or plastic profiles for anchoring or edge protection. When bonding the profiles, care must be taken that the connection is made with at least one outer layer. If profiles are to be fastened to the inner side of the outer layer, they can be glued with a two-component adhesive based on PUR or epoxy resin after the local removal of the core material with drills or cutters. The contact of honeycombs and core material with aggressive solvents and cleaning agents should generally be avoided.

Painting/Labeling
The EPOXY PRIMERS supplied by us and the polyester-coated surfaces can be subsequently coated with wet lacquer or digital printing or labeled using foil.
Polyester-coated surfaces must be lightly sanded beforehand and then cleaned and all grease removed. An additional primer for improving the optical quality or adhesion of the topcoat may be helpful. The contact of honeycombs and core material with aggressive solvents and cleaning agents should generally be avoided. Accelerated drying can be carried out at max. 80°C.

Our pre-painted aluminum outer layers

We provide a selection of pre-painted aluminum outer layers with different colors on PVDF and POLYESTER basis for our products. The coil coating has several advantages compared to alternative methods:

  • Quality: The coil coating ensures a uniform and smooth coating, whereas wet lacquer or powder coating of large areas can lead to orange skin, color runs or dirt trapping.

  • Reproducibility: Thanks to the controlled coating process, color differences between independent coatings are minimal.

  • Corrosion resistance: Before the coil coating, the aluminum strips pass through various cleaning stages. This prevents dirt trapping under the paint coating, which prevents subsequent color dissolution by corrosion in the contaminated area.

  • Environmentally friendly: Coil coatings are environmentally friendly. Processes with solvent emissions run in separate, controlled rooms. The manufacturer complies with current EU directives. In addition, coil-coated aluminum sheets are completely recyclable. They can be disposed of at any collection site for subsequent melting and re-use.
