Pontoon Deck Support Back Plate

About this Item

Pontoon Deck Support Back Plate

The Pontoon Deck Support Back Plate is made from hot-dipped galvanized steel. Support brackets for pontoon cradles.  2″ x 6″ wood are typically mounted on the brackets. Designed to hold the pontoon boat from underneath the dock. Suspends the pontoons on either side so the weight pressure is not on the actual pontoons. Fits up to 6″ I-beam. Backplate only. Does not include bracket or fasteners.

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.
