Best metal for gate near ocean

13 years ago

We want to put up a gate so in this picture when you approach the house at this point you will be in front of this gate. It will be almost 6X6. The architectual detail on the side make it a bit weird. I need to know what is the best metal to have at the coast or what we do to make any metal last? I want it to be black or silver in color. My understanding is stainless steel is the best but I am assuming that would be very expensive? Nothing metal last more than 6 mo. At 2 yrs we have to replace all the pulls and hinges put on our fence by the fence builder due to rust. Thanks, Alyx

Hot-dipped galvanized steel will be the cheapest solution. Make sure to tell the galvanizer you want G90 as a minimum.

Weld the gate and have the entire gate galvanized. Be sure to paint it after installation.

" Be sure to paint it after installation. "

And remember you will have to etch the gate to get the paint to stick long term.

I would use plain steel, corrosion resistant primer, and two coats of paint then just count on repainting every few years and replacing at some point.

The hinges will be the first part to fail since no paint (or galvanize) will stand up to the movement of the hinges on the hinge pins.

Konrad is correct 316 Stainless Steel, and make sure the hinges and anchors are also stainless steel. Note, that it is called "Stain-Less" steel, not stain-proof, or rust proof steel. So I would also have it powdercoated with a Zink rich primer, and then a color coat, and for extra protection a final UV clear coat.
