Hi All,

Looking to have a black A frame made, I assume the ones I have seen are powder coated ?

Is the best material to use still stainless or could I use aluminium ?

Thanks John

If you were going to make it in stainless it would be sacrilege to powder coat and not polish it!
Aluminium is usually the material used for powder coating

Yea I think jambo had stainless with a coating which peeled off

I have some stainless seat bases that are powder coated. Done professionally but they did struggle a little with contamination and did them 3 times. Been good for 3 or 4 years now. The guy at the powder coaters said powder coating was not waterproof and salt water will eventually penetrate it if it’s under water or heavily exposed.

I have a black powder coated A-frame and love it!...Goes well with a Black Rib!

...I had mine done before it was polished...which is a very labour intensive processes in itself!!!
Especially on a large Double.
The fabricator/maker who I know personally was more than happy to powder coat!..The BIG thing is to SHOT BLAST and 100% degrease the SS to form a good "key" before Powder coating

PM me if you want details....but yeah it works well if done properly

Not sure but I'd think Alloy may be just as easy...or easier.

Will go ahead with an ally A frame,

Just one thing i would tell of is my highfield had a powder coated a frame and was spot on ,with one exception ,during the manufactur a ready made ally rope cleat had been welded on each side (perfect idea ) ,and it must have been a different grade of ally as the thing was acting like a sacrificial anode ...... you can see this on virtually all the grey highfield a frames

Powdercoating does not hold up well long term in a marine environment. Seen many a nice boat with blistered metal work with powdercoating peeling. I have had all my recent stuff painted with a commercial epoxy primer then a marine epoxy finish and it is super tough.
