What is slotted angle?

Slotted angle is a light cold-formed steel angle punched along both legs with a repeating pattern of slots and round holes, so any two pieces bolt together at any point without drilling. Invented for adjustable shelving (the Dexion pattern), it now builds storage racks, archive and stock shelving, workbenches and tables, machine guards and frames, conveyor supports, partition frames, display stands and site-camp furniture. Two sizes cover most work: 40 × 40 × 2 mm (general) and 50 × 50 × 2 mm (heavier racks); 36 × 36 is the light shelving size. We roll and punch it on our own line from pre-galvanized strip or painted cold-rolled steel.
