The usual route for a bench cabinet is a plywood box with a bought frame bolted around it. This build flips that: welded steel tubing and angle iron form the skeleton, while pine lumber, OSB and rebar handle the woodwork and the hardware. The finished piece is freestanding and industrial in style, with a matte black structural frame and a warm brown stained top under a smooth topcoat.
The metalwork came first. Square tubing and angle iron were measured and cut with an angle grinder, the sections were joined on a stick welder, and the framework was sprayed with primer and a dark coating. The top started as pine beams glued face-to-face, with the ends cut square and the resulting holes plugged with wooden dowels. Three threaded rods, tightened with nuts, reinforce the slab, and defects were filled with wood filler and black epoxy before an orbital sander brought the surface smooth.
The storage side rewards a close look. Drawer boxes are pine boards over OSB bases, driven together with an impact driver, and the handles are my favourite detail: lengths of twisted rebar welded onto flat steel brackets. In my view, securing the finished top with screws driven from underneath is a smart call, since the top face stays free of fastener heads.
One open point before anyone copies it: the drawer boxes use OSB bases, and mounting slides onto OSB seems like the question I would want answered first. The black epoxy in the filler is worth a thought too, since epoxy is known to scratch easily and filled spots could mark before the surrounding pine does. Small caveats beside how solid the whole unit reads.
