D-36 is a low carbon steel.
I'm not sure where you read this, but I'll take your word for it because low carbon steel and mild steel are essentially synonymous; they're basically the most common form of steel available and there's noting special about it. In terms of strength, it's one of the most malleable (highly deformable under compression) grades of steel which is why it is easy to flatten and turn into sheet metal.
I don't have a problem at all with low carbon or mild steel; the tubular bumper I would like to buy is constructed of 0.120" wall mild steel. My issue was with the fact that the manufacturer is referring to it as "carbon steel" like it's something special when in fact every type/grade of steel known to mankind has at least a small % of carbon in its composition. Now if it contained some magical element like kryptonite or unobtanium... ok then I would want to point that out too.

A little research indicates that it is 7 gauge or 3/16"
Again, I couldn't find this on the website either, but I only looked briefly. Technically only 7 gauge
stainless steel is truly 3/16" (0.1875"); 7 gauge mild steel is slightly thinner, but it's close enough to call the same.
Agreed that a 7 gauge plate bumper should definitely be stronger than the OEM bumper and do a better job at minimizing damage in the event of smacking bambi at speed, but I still don't think it's in the same ball park with any of the above mentioned tubular bumpers in terms of strength.
As for the bumpers appearance, the style is not for me and I don't think it goes well with the overall look of the Raptor. I wouldn't put it on any Ford just because it's called the Magnum RT bumper and both of those names scream Dodge... ok that's a joke. The OP was asking for help and recommendations and seemed specifically concerned about deer protection, so that's what I was trying to help him with. After reading his post again, I don't even think he really loves the look of the bumper because he described it as 'not looking terrible.'
