Technical Data Of Aluminium Honeycomb Panels
HWSTRONGER honeycomb panel is aluminum sandwich-type panel with high rigidity and extremely low weight. It is the ideal material for a host of applications in architecture, transport,display or industrial production.
In contrast to conventional honeycomb composite panel, our system components- the “aluminum honeycomb core” and the coil coated” aluminum cover sheet” are bonded in a continuous process.
The advantage: product quality and surface evenness; the materials does not become brittle-hard but shows tough and resilient properties and excellent peel strength.

Coating System
Paint Finishes
The aluminum cover sheets of HWSTRONGER Aluminum Honeycomb Panel are factory pre-finished by ”Litong” with a PVDF(fluorocarbon) coating applied by a “Reserve Roller Coating” process. The total dry-film thickness of the coating in minimum 40 microns, consisting of a chromate conversion coating, an inhibitive primer and a topcoat. The coated surface is complied strictly with the “Specification for coated coil for exterior building applications” issued by ECCA (European Coil Coating Association) to achieve the quality.
Lacquering
The surface of HWSTRONGER Aluminum Honeycomb panel are coated using high quality lacquer system. The systems combine good formability and excellent surface durability. They are extremely resistant against weathering, strong solar radiation and pollution attack.
The PVDF (i.e. fluorocarbon) coating is applied to the aluminum coil prior to lamination into a honeycomb panel, using a continuous coil coating process system imported from Korea. The multiple layers are individually stove at temperature between 200℃ to 260℃. The quality of coating is tested according to standards established by ASTM (USA).
The finished surface of HWSTRONGER Aluminum Honeycomb Panel is factory protected with a self-adhesive peel-off film. The reverse side of the panels is polyester lacquer pre-finished or in mill finih by our factory applying the same process and is comply with the same standards and specifications.
