Mill Relationship
Nucor proximity & mill-adjacent advantage
Our Performance Master processing facility is co-located adjacent to Nucor Crawfordsville — one of North America's largest sheet mills. The geographic relationship means master coils move directly from the mill to our slitters with a single short truck leg, instead of the two long-haul legs typical of distant processors.
Nucor proximity is one sourcing advantage within a broader domestic and international mill network. Customers receive traceable material with mill certifications that flow through every shipment, while maintaining flexibility across market conditions.
Read the Mill-Adjacent Advantage →What this means for quality
- Broad mill sourcing with heat-level traceability across domestic and imported material.
- One truck leg vs. two — reduced handling damage, edge dings, and transit exposure.
- Mill test reports tied to the original Nucor heat travel with every coil.
Traceability
CMTR — Certified Mill Test Reports
A Certified Mill Test Report (CMTR) is the mill's record of the chemical composition and mechanical properties of a specific heat of steel. It is the foundation of traceability for regulated and OEM supply chains.
At Metal Master, every processed coil and shipment is linked back to the original mill heat number. The CMTR — including chemistry, tensile, yield, and elongation data — travels with the material from inbound receipt through processing, staging, and outbound delivery.
CMTRs are provided with every shipment by default and are retained electronically for the life of the customer relationship.
Information flow on every order
- 1. Mill issues CMTR tied to heat number.
- 2. Heat & coil ID captured at inbound receiving.
- 3. ID carries through slitting / CTL onto every mult and skid tag.
- 4. CMTR PDF released with packing list at shipment.
Automotive
PPAP capabilities & IATF 16949 alignment
Metal Master supports Production Part Approval Process (PPAP) submissions for automotive and Tier-1 customers operating under IATF 16949. We are not an IATF-registered manufacturer, but our quality system is structured to provide the documentation, traceability, and dimensional evidence required for the elements of a PPAP package that originate at the service-center level.
We routinely supply submission-ready packets including design records, material certifications, dimensional results, and control-plan inputs in support of Level 1 through Level 3 PPAP submissions.
Typical PPAP package
- • Material CMTR
- • Dimensional inspection results
- • Process flow diagram
- • Control plan inputs
- • Packaging specification
- • Part submission warrant (PSW)
Process
Quality process — inbound to outbound
Every coil moves through documented quality checkpoints from the moment it arrives at Performance Master to the moment it leaves on an outbound truck.
- 01
Inbound receipt
Verify heat, coil ID, weight, and CMTR against mill paperwork.
- 02
Incoming inspection
Surface, edge, and gauge verification before release to staging.
- 03
Processing
Slit or CTL to spec with in-process gauge and width checks.
- 04
In-process QC
Operator sign-off and recorded dimensional checks per work order.
- 05
Final inspection & tag
Coil/skid tagged with traceability data; packaging per customer spec.
- 06
Outbound documentation
Packing list, CMTR, and any required PPAP elements released with shipment.
