So to equip one german platoon in 1936, you'll need 309 kg of steel, not including ammo.
Your infantry has no cutlery to eat with, no tents to sleep in, no kitchen to cook food for them and no jeeps or motorcycles to do recon for them. They carry no binoculars, no radios, no other steel gear or tools, no mines, no barbed wire and no grenades.
Overall a German Infantry division using so little steel per platoon probably wouldn't be an effective fighting force lacking all of the above
While your clearly put some efforts of trying to summarize the heavier weapons needed, as discussed to great detail in other threads infantry equipment encompasses a whole lot more then just weapons, and it also includes a lifetime of ammo consumption and spare parts for everything produced as already pointed out ( although that is true for the tank as well even if I suspect the tanks ammo per own weight ratio is much smaller ).
