I'm tempted to just scrap the whole thing and buy a commercial PVC rack, but I might still do my original idea of high-grade plywood (much stronger than melamine), and seal it with acrylic paint.
I would highly recommend going the plastic route. If you want something cheap and fast, then melamine is an OK solution. Clearly it worked for reptile keepers for many years before the introduction of plastics. However, if quality and longevity are your primary goals, there is really no reason not to go with a plastic rack. Modern materials insulate well, tool similar to wood, and are water-proof.

Buying a commercial rack is certainly the easier way to go. There are a plethora of choices out there that are readily available and some manufacturers (animals plastics for sure) will customize your request. That said, if you really want to build a rack yourself, this is how I would do it:

Material:

Per the above, I would without a doubt select a plastic material to build with. There are tons available from local plastic companies and many can be shipped to you. Eplastics for example, will even CNC pieces to your specifications and then you can assemble a design of your own making. PVC has become the most commonly available plastic for most reptile cages for the following reasons: It tools well, it is water-proof, it can be made flame retardant, and most of all, it is inexpensive relative to most other plastic choices. There is a mishmash of information regarding PVC and out-gassing / toxicity. Some sources claim it is harmless and others suggest carcinogenicity. Personally, I have set my standard to use plastics that are both FDA and USDA approved the best I can. FDA approved for human food contact is generally my preferred metric. Most industrial PVC plastics do not meet this criterion.

Plastics that do generally include: Polyethylene, polypropylene (the translucent material most tubs are made out of), acrylic, and acetal. There are more, but these are the most common. The downside is that these are usually more expensive. For a rack, it probably matters less than an enclosure as they snake is still in a polypropylene tub. My favorite of these plastics is the HDPE (high density polyethylene) that constrictors NW uses, which is a lighter version of King seaboard / starboard. The material is FDA, USDA certified, UV stable, and extremely non-porous. Urates (and everything else) still very poorly making it extremely easy to clean up. If animal plastics used this stuff instead of PVC, they would basically be the perfect enclosures in my opinion.

Design:

This more depends on you and your purposes for the rack. Is the rack for babies / hatchlings? Is it designed to permanently house adult ball pythons? Do you want to house other snakes there?
Either way, and this is more expensive, I would probably do 4-6 shelves with a large ultratherm heat mat recessed into each one that would essentially heat 2-4 tubs on each shelf. I would then have a herpstat 4 or 6 controlling them. One probe for each shelf. You can use a single probe, but it gives you more control with each shelf being individually monitored.I would definitely get whatever plastic material you make the rack out of in at least 3/8" thick, with 1/2" or 3/4" being better. Narrower plastic makes assmebly more difficult as you have less material to work with when screwing everything together.
