Will 8020 T-Slot support 5000 lbs

We are designer/distributor for 80/20, and the stand shown uses a lot of expensive gussets and plates. If you want that steam punk look - then this is the way to go, but we build stands for heavy aquariums that cost less. A lot of people focus on compression strength which is only one part of the equation. Wood has pretty good compression strength but it is very weak when the weight shifts up top - screws can pull out with way much less force than the compression strength. In any structure - you should focus in on the weakest link. With wood - its the fastener strength and the horizontal beams - especially over time where humidity levels and moisture can radically reduce their capability. I would probably never recommend an aluminum t-slot stand for a 20 gallon tank, as wood is much more cost effective and plenty safe. But as you get up into the 1,000 - 4,000, 90 - 300 gallon tanks, I would definitely recommend that people consider setting aside a certain % of their overall investment for a good safe stand. Makes no sense to me when people tell me about their $10,000 aquarium, but say that spending $1,000 on a stand is way too much. If you live in earthquake prone areas, you also need to really think about side-to-side strength as this is the worse case scenario you need to protect your investment from. This means extremely strong fasteners to ensure the vertical bars stay vertical. Here is simple version (black anodized) which would cost less....
