Aluminium Quality Inspection

Quality inspection is a sequence of planned checks, not a single look at the finished unit. The inspection plan should reflect the approved drawings, samples, specification, fabrication method, and intended use. It can cover incoming profiles and accessories, machining, assembly, glazing, operation, finish protection, packing, and records.

Define what acceptance means

Inspectors need current documents and measurable criteria. Critical dimensions, tolerances, diagonal checks, drainage holes, fasteners, gasket joints, sealant preparation, hardware operation, and visible finish can each require a different method. Approved samples help align visual expectations, while calibrated tools and clear check sheets improve consistency.

Check at useful hold points

Problems are easier to correct before the next process hides them. Incoming material can be checked before cutting; first-off machining before batch production; frame geometry before glazing; and operation before packing. Nonconforming work should be identified, separated where necessary, assessed by an authorised person, and recorded with its disposition.

Keep the record connected

A useful record identifies the product or batch, drawing revision, date, inspector, criteria, result, and corrective action. Site teams should also inspect openings, supports, perimeter clearances, fixings, seals, drainage, protection, and final operation. Inspection does not replace engineering or testing: project-specific performance claims require appropriate evidence and approval. Acceptance criteria should be agreed before work begins so every reviewer interprets the inspection result against the same reference.
