Cutting, bending, identification, and controlled modification
Preserve identity through production
Before cutting, match the material to the scheduled mark, size, grade, coating, shape, and length. Retain the link to material certificates or other required identification when stock is cut and rebundled. A short offcut is usable only if its identity and geometry remain suitable for the intended item. Mixing remnants by appearance makes later verification difficult. Revised schedules also require a physical inventory response so that superseded shapes do not remain indistinguishable from current work.
Set up for the specified geometry
Use the approved bend dimensions and the appropriate equipment settings, pins, and material instructions. The smallest available pin is not automatically suitable. Tight bends concentrate strain, and unauthorized heating or repeated reforming can affect steel or its protective coating. Composite and stainless products may have additional handling restrictions. Do not apply a familiar carbon-steel method to every material. Check a first item after it is released from the machine, because springback and setup geometry can make the free-state result differ from its loaded position.
Control cutting and machine hazards
Confirm that the cutter or bender is suitable for the actual section and material. Support long stock and offcuts to prevent unexpected movement. Keep hands clear of cutting, bending, and pinch zones; gloves do not authorize contact with moving machinery. Guards must function as intended. A jam requires the appropriate hazardous-energy isolation and verification before someone reaches into the mechanism. For abrasive cutting, check the wheel's suitability, condition, and speed rating, then control sparks, flying particles, noise, and nearby combustible exposure.
Verify rather than improvise
A batch can repeat one setup error many times, so initial and ongoing checks are valuable. Compare individual legs, angles, overall dimensions, and the correct reference points, not merely the sum of all lengths. A bar outside tolerance is identified and routed through the approved correction or disposition process. Do not conceal a poor fit by hammering it into the cage or changing its label. Keep kerf, trim, and bend allowances distinct when calculating stock needs. If a fabrication formula is supplied, apply that formula with consistent units rather than combining it with a remembered allowance from another system.
