Multi-Cell Profiles (Hollow Box Deck Profile)

Multi-cell FRP profiles are long hollow-box sections with multiple enclosed cells, usually used as lightweight decking or structural panels. They leverage the high strength-to-weight of multiple webs inside one profile. These hollow pultruded decks carry loads like gratings but are solid on top for clean surfaces. Their hollow cells mean they can achieve great stiffness without solid mass, and they never corrode internally or externally.

Continuous fiberglass construction (sealed box cells prevent water ingress)

Benefits

Extremely light for floor panels or modular bridges
Integrated drainage (cells can be vented to allow water flow)

Applications

Walkway or bridge panels in corrosive plants (chemicals drain off inside)
Deck flooring in marine vessels (saltwater won’t degrade interior)

Technical Specifications

Box heights from ~50 to 150 mm, widths customizable
Load-bearing capacity engineered per project
