I've built a few chutes and made most of the mistakes.
First, is your gate and chute going to be in a barn or some shelter? If inside, things are simplified as to materials. If outside, the chute needs to be made from a strong, decay resistant wood, like white oak. If you have oak trees to cut the expense problems are greatly simplified. Find sawmill, cut trees, take to sawmill, have 2 x 6s sawed. Treated pine 2x6s probably would work but expensive.
If inside can use any type of 2 inch thick lumber, or less for part of the run. Cows look for daylight to escape through, so an ideal chute material is plywood. 1/2 thick would work if you have the posts close together, like 4 feet apart.
Whatever the material, the chute should be 6 1/2 feet high, sides maybe 2 feet apart, that depends on the size of animals you are going to work. For 300 or so pound calves, you could collect some old pallets and line the chute with them, UP TO THE CROWDING PART OF THE CHUTE, 6 FEET OR SO BEHIND THE HEAD GATE. Calves will try to climb the walls when in the head gate and may catch their feet between the boards in a pallet. I made spacers of 2x4s and plywood to take up the space behind the head gate so as top narrow the working area down.
Is you head gate the type that opens up to let the cow escape to the front or do you plan to let them back up from the head gate and escape to the side. If to the side, what you are suggesting should work but it needs to be wide enough for the cow to get out easily. Commercial gates look to be 5 or 6 feet long. The fastening system will have to be very strong. Your tame cows won't be tame in the headgate.
You mentioned using tube steel gates. IMO most of them are not strong enough and the cows will try to get their head in the openings and will tear the gate up. Lining them with plywood might work, but they really need to be welded from 1 1/2 inch black iron or galvanized pipe. Look over a commercial one carefully.
I assume you have plans for making access to the working chute. It helps if it is next to and area that the cows regularly pass through with a gate to shift them into the working chute.
I've probably forgotten something so post back if you have questions.
