Product Scope: 1,800 m² Clear-Span Portal Steel Warehouse (S355JR Columns/Rafters, Z200 Purlins & EN 14399 10.9 Bolt Lots — ~74 Tons)
ILLUSTRATIVE CORPORATE SPECIMEN (ZERO CLIENT DATA DISCLOSED): Client names, factory identities, heat/certificate numbers and commercial figures in this specimen are fictionalized to protect strict B2B NDA confidentiality. Scoped commercial/visual engineering record — not an accredited laboratory test certificate or statutory structural sign-off.
01 · ASSIGNMENT REGISTER & EXECUTIVE GATE SUMMARY
Primary portal columns (C-01..C-14) and rafters (R-01..R-14) match shop-drawing overall lengths and splice end-plate hole centers (±1.5 mm). However, 3 rafters showed low epoxy DFT (105–118 µm vs 160 µm spec) along bottom flange edges, and M24×85 Grade 10.9 HV nut/washer boxes lacked EN 14399 k-class batch labels.

| Ref. | Subsystem / Inspection Parameter | Buyer Specification / Benchmark | Recorded Field / Desk Evidence | Evidence Basis | Required Buyer / Supplier Gate Action |
|---|---|---|---|---|---|
CHK-01 |
Splice End-Plate Thickness & Bolt-Hole Pitch | 25 mm S355JR end-plate; 26 mm holes @ 120×220 mm gauge (±2.0 mm) | Sampled 8 rafters + 6 columns: plate thickness 25.1–25.3 mm; hole centers within ±1.5 mm; zero flame-cut oval holes. | Observed / Verified | Dimensional geometry accepted for site bolting. |
CHK-02 |
Hard-Stamped Piece Marks vs. Erection Drawing | Hard-stamped + tag-labeled member IDs (C-01..C-24, R-01..R-24) | Hard stamps legible under primer/topcoat on all 14 sampled primary members; barcode tags wired. | Observed / Verified | Compliant; retain tag register in packing list. |
CHK-03 |
ISO 12944 Epoxy/PU Coating Dry-Film Thickness (DFT) | Nominal 160 µm total DFT (80% >=160 µm, min >=128 µm rule) | Web faces averaged 174 µm; 3 rafters (R-04, R-09, R-11) measured 105–118 µm along lower flange edges. | Open / Hold Gate | Hold R-04, R-09, R-11 for stripe-coat rework + re-measurement photo. |
CHK-04 |
EN 1090-1 FPC Certificate & Factory NDT Dossier | Valid Notified Body FPC (EXC2), WPS/WPQR and UT/MT report on full-pen welds | Reviewed Notified Body FPC cert, welder quals and third-party UT report #UT-882 covering haunch butt welds. | Document Reviewed | Include signed DoP + UT report PDF in final customs/handover binder. |
CHK-05 |
Cold-Formed Roof Z-Purlins & Eave Struts | Z200 × 2.00 mm S350GD+Z275 pre-punched sleeves, strapped on timber skids | 4 sampled Z200 bundles measured 2.01–2.03 mm coated; zinc surface dry with zero white-rust staining. | Observed / Verified | Ready for loading; keep indoor storage until trailer arrival. |
CHK-06 |
Anchor Bolts & EN 14399-3/4 Grade 10.9 HV Fasteners | Sealed kegs with matching 10.9 bolt, nut & washer batch certificates + +5% spare | M24 10.9 bolt kegs present, but 4 nut cartons were generic 8.8 stock instead of matched EN 14399 HR/HV 10.9 nuts. | Open / Hold Gate | Mandatory replacement with certified Class 10 HV nuts before truck loading. |
Scoped B2B visual field verification, random dimensional spot-sampling and documentary cross-check.
Field gauges zero-checked prior to measurement; heat/batch IDs cross-referenced against presented 3.1 MTCs.
Advance or balance wire release remains conditional upon closing all Open / Hold items logged on Sheet 2.
