This is part of a post from lawnsite.com about the deere 7-Iron & stamped decks in general. I use an Edge HC deck, which is a 9-guage copy of the 7-Iron.
You either have a bias towards the deck type you learned on, or just haven't done your homework. The ONLY reason all manu's do not use a stamped deck for their commercial mowers is because none of them can afford the huge and extremely expensive press and dies to make their decks stamped. If any of the manu's that make the claim that their deck is better because it is "fabbed" could actually make their decks stamped as well, they'd do it in a heartbeat. It is faster to produce, much more consistent in shape, less chance of getting one that is slightly warped from the factory, has nowhere near the number of places for rust to form, or metal to crack from fatigue etc. A square corner is never as strong as a rounded one. The Romans knew that several thousand years ago. Grass does not stick to the underside of a stamped deck nearly as badly nor as quickly as it can and usually does to a fabbed deck. Of course other manu's will say fabbed is better, because what else can they say? "This is s good as we can make it on our budget right now?"
Stamped 7 gauge steel is still 7 gauge steel, and is more than a lot of manu's actually use for the entire deck such as the decks made by Ferris , Exmark etc that are partial 10 ga and partial 7 ga.
Do a search here of most desirable commercial decks for any type of cutting and the stamped JD deck is one of the top two rated decks to have.
Do you know why most HO grade stamped decks of any manu you see at BB stores are rotted out in short order? It is becvause the people that buy them, do so for their own use, more often than not they are not mechanically inclines, are lazy and just want the grass cut, or let their kids do it for them while they are at work. In any of those cases, the decks get abused, and little to no care at all, and usually the blades are duller than dull. You seldom see an HO get down and clean under the deck. If HO grade mowers sold at BB stores had fabbed decks of the same gauge steel, they'd be rotted out in short order too, and for the same reasons. You cannot legitimately claim that a stamped deck is bad because some HO doesn't take care of it, especially since there are NO fabbed decks on HO grade mowers to compare to.
Here is a pic of a plain, ordinary JD garden tractor with a 12 gauge stamped steel deck. It is almost 27 years old now, and still mowing grass. It has mowed an enormous amount of grass in its lifetime, and it has been fairly well taken care of at the same time. It is not rotted out, and cuts and stripes beautifully-

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
