Fiberglass covers

Largest U.S.
manufacturer.

We are the largest U.S. manufacturer of fiberglass hopper-barge covers, used primarily on grain barges. We also produce fiberglass covers for barges used in the U.S. coastal trade.

Covers are manufactured under the SynTechnics name — the same engineering team, the same shop, and a name that still appears in specifications written in the 1980s.

Overview of NABRICO FRP barge cover construction

How they are made

Composition.

NABRICO barge covers are composed of Fiberglass Reinforced Plastic (FRP) laminate. The color is molded into the surface by use of a gelcoat and requires no painting.

Each barge set is comprised of male, female, and end cover sections.

Handling & storage

Built to stack.

Barge covers are equipped with Lifting Eye / Clamp Assemblies for easy removal, and they are made to be stacked for storage.

Refer to the NABRICO FRP Lift-Off Barge Covers Handling, Stacking, and Storage Procedures for complete instruction.

Stacking, step by step

Square, stable, secure.

Every NABRICO cover set is engineered to stack cleanly for storage and transport — locator pins, stack supports, and nesting profiles keep the load square.
