I typically use 1/4" thick 316 stainless steel sheets. The size varies depending on the load from 1" x 2" strips for small hardware to 12" x 12" sheet stock ($130 at McMaster) for the mast crane cleat. One easily found source is McMaster Carr (https://www.mcmaster.com/metals/stainless-steel/shape~sheet-and-bar/corrosion-resistant-316-stainless-steel-6/thickness~1-4/). An image of the link is attached at the end of the email.
