Handling, storage and introductory quality control: principles and terminology
Why the trip from delivery to shipment is where metal is damaged, the words quality assurance, quality control and inspection, and the safety limits that apply before anyone lifts a sheet.
You will be able to: Explain why handling and storage damage metal and hurt people, define quality assurance, quality control and inspection, and state the safety limits on aisles, stacks, lifting and sharp edges.

Handling, storage and introductory quality control: materials, standards and design constraints
How water with no air stains zinc, painted steel and aluminum, why cold metal sweats, the time limits publishers give, and which rules and whose advice apply.
You will be able to: Name what zinc-coated, painted and aluminum sheet each fear in storage, explain condensation and dew point, recognize the time limits publishers give, and say whose rule applies in the shop, on a jobsite and from a supplier.

Handling, storage and introductory quality control: defects, verification and case study
Eight defects to recognize, the stop-and-report steps, who decides what is acceptable, a worked case study and a storage walk-round checklist.
You will be able to: Recognize eight common handling and storage defects, say what to do and not do when you find one, work a case study from evidence to cause to prevention, and run a storage walk-round.

Practical task
Build a job packet for one made-up incoming delivery: a pallet of 24 ga galvanized sheet and a bundle of painted flashing, delivered on a cold day. Decide where and how to store it, how to handle it, and what to record, and show your sources.
Hand in
- A decision rationale: where the delivery is stored, how it is raised, tilted, covered and separated, and why, each reason tied to a named source
- A sketch of the storage set-up with labelled parts and a legend, marking the cover, the spacers, the air path, the aisle and the tag
- An assumptions sheet with units: sheet size, gauge, weight per square foot, the weight of one sheet and of the bundle, delivery and storage temperatures, and the dates for a stock-age check
- A receiving and storage checklist the next person can follow, ending with what to do when an answer is no
- A defect analysis of one made-up defect: name it, give the evidence, the cause, the action you take and the prevention, and say who decides if it is acceptable
Rubric
| Criterion | Meets the standard when |
|---|---|
| Sources | Every storage and handling choice cites the publisher it comes from and labels it a maker value, a trade guideline or an OSHA rule, and no AFS procedure is claimed. |
| Moisture and temperature | The packet explains water with no air and the dew point, uses a dew point read from a table for the delivery temperatures, and says how cold metal is brought to temperature. |
| Weights and lifts | Sheet and bundle weights are worked from area and weight per square foot with units, compared with the 51 lb starting value, and any lift over it is assigned to equipment or a trained team. |
| Stock age | The packet applies oldest-first rotation, shows a date calculation against a published guideline and says the supplier's own limit decides. |
| Safety and reporting | Aisles are clear, stacks are stable and limited in height, sharp edges call for hand protection chosen by the employer, and each defect is stopped, separated, photographed, tagged, reported and written down. |
