Aluminum Faced Aluminum Honeycomb Sandwich Panels - Cellite™ 220

The Cellite™ family of Sandwich Panels has been used for many years to build composite components, bonded assemblies, and lightweight structures for the marine, defense, aerospace, rail, and motorsports industries. The panels can be machined, fabricated, and assembled into many types of structures for a broad range of applications in various industries.

The exceptional features of the Sandwich Panels are derived from a blend of facing skins and core, bonded using high-performance adhesive. By tailoring the separate elements to meet individual conditions, the subsequent benefits can be used for many applications where low weight and high stiffness are particular necessities.

TRB Lightweight Structures offers many different standard Cellite Panels as well as customized products to cater to individual requests.
