Steel tubing for bicycles is around 1mm thick. The tubing in the picture looks like it's in that range. I think the problem is that they cut out the hole for the shock mount. I would assume that most mounts like that are welded to the tube
without cutting a hole in the tubing. For a really cheap HelMart bike, I would think it would be cheaper. Cutting tubing is an extra step and you have to weld all the way around the mount as well as align it.
