Loading alley frame 8 ft

Straight alley section with barred sides. A planning layout — chutes take heavy loads, so build it stout.

Steel you'll need

A cut sheet: every piece drawn to scale with tip-to-tip length and the saw setting for each end
A shopping list and a cutting plan that gets every piece from the fewest sticks
Build steps: what to tack first, how to check square, and a weld order that keeps it straight
A 3D model you can resize — change a size and the cut list follows

Safety note. Load-bearing: not engineered or rated. Build heavier and have it checked if people or heavy loads will stand on it.
