Run each coil through the right profile, length and punch pattern, and prove it on record.

A roll former takes slit coil of galvanised, painted or plain steel and runs it through a series of roll stands. A flying cut-off or a press shears each piece to length, and a punch unit can add holes or notches. Output is channels, purlins, roofing sheet, door frames and racking uprights, each in the gauge and coating the customer ordered. Tolerances are tight.

Roll forming software starts with the coil and ends with the bundle. Roll sets, line speed, cut lengths and scrap are recorded for each run. Nothing is retyped. Send a sample job card and we start from it.

Orders arrive as a profile code, a gauge, a colour or coating and a cut list of lengths and quantities. The planner groups orders by coil and profile to avoid changeovers, since swapping roll sets takes the line out of production. Coil comes in from a mill or a slitter with a certificate for thickness, yield strength and coating weight, and each coil is weighed and tagged.

At the line, the setter fits the roll set, threads the coil and runs trial pieces. Length, flange width, bow and twist are measured against the drawing before the run starts. Pieces come off the run-out table and are counted into bundles that are strapped, labelled with profile and length, and stacked on the dispatch bay. Counts matter. Offcuts and coil ends are weighed as scrap. Any coil left over returns to the rack with its remaining weight.
