First, some PLYWOOD info - http://www.pfsteco.com/techtips/pdf/tt_plywooddesigncapacities
If the debate was between thicknesses, and plywood was your desired building material, 1/2" would be more than enough. No matter what you do though, the space lost will be greater with woods metal if taking the over all dimensions into play.
BEARINGS Thickness of the 608 bearings (skateboard bearings) plus additional mounting hardware needed to secure them will be comparable to drawer slides in some instances. 608's are ~1/4" wide, plus a nut or bolt. If you double up on the bearings , your total overall thickness could be over 3/4" - heavy duty drawer slides are generally 3/4". https://www.tactics.com/info/choosing-skateboard-bearings
We are in sandy environments daily. HDPE would end up eating everything up with all the sand that would eventually end up impregnated in it. With the loads our setup will incur, plus the length of the pull out we want, slides fit the bill. I don't want struggle with HDPE and the issues of keeping it clean for us. With the slides, we can spray them off/out.
METAL Weight of metals - https://www.metalsdepot.com/stainless-steel-products/stainless-sheet-316 - select the type and gauge and you can get an accurate figure. we are using a 14 gauge 5'x10'sheet. only a couple of inches will be waste. ~150lbs -drawer slides in transit are 58" locking. UPS has the total weight ~34lbs.
if you go thinner material in steel or go AL/ - you will be lighter. Beaches and AL aren't the best, that's why we went SS.
My children and I want to build a finger press break. Nothing off the shelf is able to 60" plus material that we came across. Nothing short of industrial and industrial price tag. Lots of 48" and smaller. Even conversion kits for the Harbor freight presses. 48" and the smaller 20 Ton. Material, 2 jacks, casters, and welding supplies would bring a build of a ~6' finger break less than ~$800 so far from what I priced out. Each time I have a shop bend something for us, its ~$200 or less if I don't haggle with them. Adds up quick. $10 per bend with a minimum of $100 charge is about average from what I'm finding.
WELDING If there was a Makers Space or similar close to us, I could really see us benefiting. Until then, our tool chest continues to grow. Miller Dynasty 280DX TIG on the horizon too. If anyone is going to buy Shielding gasses for welding- BUY THE BIGGEST TANK YOU CAN FIND. We have a couple of the 330 CF tanks. We were charged ~$335 each and were 'given' the gas for 'free' from Matheson Welding Supply. Most places wanted a credit account and would charge ~$160 + fees yearly for bottles each!!! The cost for gas goes down when you get the bigger bottles too. Try to get 'clean neck ring' bottles. Most likely you will get a USED bottle that they have in current hydro. DATE +* is what you are looking for. DATE only is 5 year hydro, DATE +* is 10 year. In the long run, the cost of ownership vs lease is better. If You kept the bottle for 2 years on a lease, thats theist of a bottle. Most of the timethey are going to swap your "CUSTOMER OWNED" bottle forkful one and charge you for the gasses. One of our NEW (used) bottles is only good hydro until 2020, the other is 2028. They told me they swap anyway and take care of it so don't stress it.
