Galvanized Guidepost Stanchion Backup Plate

The Galvanized Guidepost Stanchion Backup Plate fits 4 in. – 6 in. galvanized boat cradle beams. Made from hot-dipped galvanized steel. Features (3) 5/8 in. mounting holes. (1) on top and (2) on the bottom. The mounting holes fit up to a 1/2 in. bolt. Measures 10 in. L with 2 in. on both flanges. All the mounting holes are on one flange.

Installation

The fastener bolts go through the stanchion mounting holes through the backplate and are secured with a lock washer and nut. The cradle beam being in the middle allows the stanchion to “clamp” tight onto the cradle beam.  Then use an optional guidepost to slide on top of the stanchion.

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.
