The sheet metal is all cut on a laser cutter. The "flanges" are dimples made from a dimple die. They add enormous strength to the overall chassis.

The metal is all 2024 T-3 aluminium. Our sponsor said that a 0.25 bend radius should be used for that alloy and thickness. We would stick to 5052 in the future, there were cracks at almost every bend point. The metal was very brittle.

Did you guys buy your own dimple die set or did a sponsor do them?

Everything was done at the sponsor's shop, laser cutting, bending, and dimpling.
