Thread: Diamond plate

Hybrid View

    Question Diamond plate

    Please excuse my ignorance, I'm a novice (metal worker) metal worker. I noticed that Lowes sells small sheats of diamond plate, the kind that looks like it's chrome plated. My question is - what exactly is diamond plate? Is it mild steel, some kind of alloy, etc? Can I weld it like I would weld mild steel? I have some ideas for some parts I would like to make out of it, but as usual, I'd like to know at least a little about it before I attempt it.

    Chop it and ride it,

    it could be polished aluminum, i'm doubting that it is steel if it looks chrome plated.

    It's most likely aluminum. You can weld it but not like mild steel.

    Diamond plating is just a design that is stamped in the metal or molded when the make it. It has the same properties as regular metals and alloys.

    It is rather expensive also. The pretty shiny one you saw is more than likely polished aluminum. They also come in mild steel and stainless. There are different thickness of them also.

    I can't speak for Lowes exactly but the Home Depot also sells those small shhets of diamond plate and thiers is aluminum.

    It's a small sheet, thin and probably more for decorative use than anything else.

    Its probably Alum. but also may have a clear coating on it too. If you're going to weld on the stuff, sand it, run a grinder/wire brush or something over it to knock the clearcoat off first.
