Pontoon Deck Support Backup Plate

The Pontoon Deck Support Backup Plate is a support bracket for the deck of the pontoon boat. It installs directly to galvanized cradle beams with the bracket. The bracket keeps the pontoon weight rest on the brackets and not on the pontoons. Made from hot-dipped galvanized steel. The backplate measures 6 1/2 in. L x 2 in. W x 3/8 in. thick.

Wood beams or support bracket not included.

Galvanized Steel

Created by dipping standard steel into molten zinc by a process called hot dipping. The layer of zinc serves as a protectant from corrosion. The protectant makes galvanized steel the best option for seawater environments. Galvanized steel typically has a rough surface and can vary in color. There is no uniform finish for this type of steel.

Galvanized steel is ideal for marine environments because of its protective layer over carbon steel. Stainless steel will react with salt water resulting in rust. The zinc layer on galvanized steel prevents this reaction.  The protective layer can corrode or fade over time. This is due to the zinc sacrificing itself to protect the base metal.
