Aluminum Sheet, Plate and Foil Manufacturing

NAICS 331315 · Primary Metal Manufacturing · SBA size standard: 1,400 employees

Aluminum sheet, plate and foil manufacturers convert ingot or scrap into coiled or flat-rolled product through melting, casting, hot rolling, cold rolling, annealing, slitting and finishing. For a mill that receives customer orders for specific alloy, temper, gauge, width and finish, the specialists turn specifications into production schedules, material requisitions and quality-test plans, then convert coil output into certified shipments while tracking equipment uptime, alloy traceability and process parameters.

What makes this business different

  • Tight alloy and temper specifications that must be met exactly for each coil or sheet order
  • Traceability from melt batch through every downstream process step to final certification
  • Heavy equipment scheduling with long setup and changeover times between alloys and gauges
  • Rolling oil, coolant and annealing furnace parameters that must stay within narrow ranges
  • Surface quality, gauge tolerance and flatness requirements that trigger rework or scrap
  • Coil and sheet inventory managed by alloy, temper, gauge and location in the warehouse
  • Customer certifications, material test reports and packing lists required with every shipment
  • Preventive maintenance windows for rolling mills, slitters and annealing furnaces

Workflows

Order specification and feasibility review

Starts when: New customer purchase order or specification sheet arrives

  1. Parse alloy, temper, gauge, width, finish, quantity and delivery date from the order
  2. Check against current mill capabilities, open capacity and minimum order sizes
  3. Identify any special requirements for surface quality, testing or certification
  4. Draft material test report template and required quality checkpoints
  5. Create a production order task with full specification breakdown

Watch for: Certain high-strength alloys require specific casting and rolling sequences; Narrow gauge or high-width orders may exceed current mill limits

Rolling and processing schedule creation

Starts when: Weekly capacity meeting and after each new confirmed order

  1. Group orders by alloy family and similar gauge to minimize changeovers
  2. Sequence melts, hot rolls, cold rolls, anneals and slit operations
  3. Assign equipment and shift resources to each operation
  4. Calculate expected coil output and yield loss at each stage
  5. Flag any orders that require expedited processing

Watch for: Rolling mills require hours for cleaning and setup when changing alloys; Annealing furnace schedules are limited by temperature ramp rates and soak times

Raw material and consumable requisition

Starts when: After production schedule is locked and weekly

  1. Explode the schedule into required ingot, scrap and master coil quantities by alloy
  2. Subtract current inventory and on-order material
  3. Draft purchase requisitions for primary aluminum, alloying elements and rolling oils
  4. Generate consumable lists for filter bags, thermocouples and packing materials
  5. Track usage versus plan and log scrap rates

Watch for: Alloy chemistry must be verified before charging the furnace; Rolling coolant and oil must be ordered to match each process step

In-process and final quality testing

Starts when: At each process gate and upon coil completion

  1. Generate test plan for chemistry, mechanical properties, surface and dimensional checks
  2. Record results from spectrometer, tensile tester, gauge and surface inspection
  3. Flag any out-of-spec material for rework or scrap
  4. Compile data for the material test report
  5. Update traceability records for each coil

Watch for: Each coil must carry unique identification through every process; Surface defects must be documented with photos and location on the coil

Slitting, shearing and packaging

Starts when: After cold rolling and annealing are complete

  1. Schedule slitter or shear jobs according to customer width and length needs
  2. Calculate and track coil or sheet yield from master coils
  3. Generate packing lists, labels and certifications
  4. Assign warehouse locations for finished product
  5. Prepare shipment paperwork including bills of lading

Watch for: Slitter knife setups are time-consuming and must match exact width tolerances; Protective interleaving, wrapping and strapping must match customer requirements

Equipment maintenance and downtime logging

Starts when: Daily shift start, after each job and on fixed calendar intervals

  1. Generate daily preventive maintenance checklists for mills, furnaces and slitters
  2. Record actual downtime, reasons and corrective actions
  3. Track roll wear, furnace element life and hydraulic fluid condition
  4. Forecast next major maintenance windows
  5. Update overall equipment effectiveness metrics

Watch for: Certain maintenance can only occur during planned outages; Roll grinding and furnace calibration require specialized external vendors

Final certification and dispatch

Starts when: When product is packaged and ready to ship

  1. Compile all test results, heat numbers and process parameters into the material test report
  2. Draft packing list, certificate of conformance and bill of lading
  3. Schedule carrier pickup according to customer delivery window
  4. Record shipment details and update inventory
  5. Archive all traceability records for the order

Watch for: Many customers require specific formats for material test reports; Traceability must be maintained for years after shipment
