Cel Components COMPOCEL AL Sandwich Honeycomb Panel

Description

Compocel AL is a sandwich panel with a core in aluminum honeycomb bonded to two skins of aluminum. A panel entirely in aluminum. It offers high mechanical properties, perfect when high rigidity and a low weight are required. Being a panel made of 95% aluminum, the fire reaction properties meet the reference standards for numerous applications.

A composite is a combination of materials with different properties. This combination gives the composite material mechanical characteristics such as lightness and resistance that are superior to those of single materials. Sandwich panels with honeycomb core and fiberglass skins impregnated with epoxy or phenolic resin (Step Series), are used to reinforce marble and semi-precious stones. This reduces the weight and increases strength at the same time. Lightweight Sandwich panels are not only used with marble and precious stones but also with any stone or ceramic material.

The Step series and the COMPOCEL AL offer various advantages and they are used in order to:

• Reduce the overall weight of the product
• Save stone material
• Improve mechanical properties
• Facilitate handling and installation
• Reduce transport costs
• Reduce CO2 emissions

Processing Methods:

• Cutting, sawing, drilling, and shaping: CEL is able to produce customized shapes, holes and processing, according to specs
• Joining and Fixing: some projects require an anchoring system to fasten panels to other surfaces. 
  • Options include: 
    • 1) Panels attached to each other by visible or blind rivets and screws
    • 2) Fixing with self-tapping screws (sealing washers) in aluminum or stainless steel
    • 3) Fastening with drilling screws

Superficial Finishing:

Compocel AL  finishes are selected carefully for indoor and outdoor applications; high quality polymeric paint such as PVDF and FEVE are available on request. CEL offers various surface treatments, in order to resist to heat peaks and temperatures. Overall orders are necessary in case customer needs specific finishes or colors; in this way all aluminum sheets are produced in a batch without any minimal pigment variation.

• Oxidation: Aluminum sheets can be covered with an anodic oxidation coating. This process increases corrosion and wear resistance, improving adhesion for paint, primers and glues.
• Painting: Aluminum panels can be finished with powder or liquid paints, combining aesthetics with environmental needs; Antibacterial and dissipating paints for indoor and outdoor are available on request.
• Serigraphy: High resolution and durable printing are possible thanks to the use of UV resistant inks.
• Edging: 
  • Flat edging (or applied edge): extrusions made of different materials can be used: aluminum, laminate, PVC, ABS, of different colors.
  • T-profile Edge: After milling the panel core, a T extrusion is applied to the edge with suitable glues. The combination of profile and glue gives strength and rigidity.
  • C – Edge profile: Extrusions are glued after milling part of the honeycomb or foam. The result is excellent aesthetic quality and durability in the outer edge.
  • Folding the upper skin over the panel edge: The core is partially removed by milling along the edge to be folded. The skin is then folded and glued upon the edge. The result is an aesthetically homogeneous and perfectly processed panel.
  • Folding for Tray production: One skin and the core are cut to get V-shaped or rectangular grooves along the folding line, without cutting the upper skin, adhesive is applied and the panel is bent in order to get the final shape.
