Types of bars

Round BarsRound bars are the most common bar form, machined into shafts, pins, bolts, valve stems and fittings.Hex BarsHex bars (hexagonal bars) are specified by width across flats (A/F) and used for nuts, bolt heads, fittings and machined components, where the hex form saves machining..Square BarsSquare bars are used for keys, machine parts, frames and forging stock, supplied hot-rolled or cold-drawn to size..Flat BarsFlat bars are rectangular sections used for fabrication, supports, base plates, gaskets and architectural trim, supplied hot-rolled, slit or cold-finished..

How they are made

Billets are hot-rolled or forged to size, then heat treated (annealed, solution treated, or quenched and tempered) and finished by descaling, peeling, turning, cold-drawing or centreless grinding for bright bar with tight tolerance.
