Shift Structure
24/5 continuous operational scheduling with dedicated maintenance windows, allowing rapid scaling for urgent project demands.
Inventory & Material Sourcing
Mill Partnerships: Direct procurement allocations from major primary mills (e.g., TISCO, JISCO, Baosteel) ensuring stable metallurgical composition and competitive baseline costing.
Spot Inventory: Over 10,000 tons of physical stock maintained across 300+ standard specifications, significantly shortening lead times for standard grades (304/316L).
Lot Control: Each master coil is tracked via internal barcode systems linking mill test certificates (MTC) to individual processed sheets.
Quality Control System
Quality assurance is integrated into every stage of production, aligned with ISO 9001:2015 quality management standards:
Incoming Raw Material Audit: Spectrometric chemical analysis verifies that incoming coils match mill certificates for nickel (Ni) and chromium (Cr) thresholds before release to production.
In-Process Dimensional Inspection: Operators perform micrometer checks every 2 hours for thickness, width, and diagonal squareness.
Surface Integrity Testing:
- PVD Adhesion Test: Scratch / Tape cross-hatch testing to ensure coating tenacity.
- Color Consistency Check: Spectrophotometer Delta E (Delta E < 0.8) colorimeter verification against master color swatches to eliminate batch-to-batch shade variance.
- AFP Performance Test: Solvent rub and water drop contact angle tests on coated surfaces.
- Final Pre-Shipment Inspection (PSI): Conducted according to AQL (Acceptable Quality Limit) 2.5 standards for visual defects, burr heights, and protective PVC film integrity.
Order Management & Lead Time
Order Processing Workflow
Technical drawing review and feasibility assessment within 24 hours of RFQ submission.
Standard Stock Orders (RTS)
Dispatched within 3 to 5 business days.
Custom Processing Orders (PVD, Slitting, Custom Lengths)
Standard production lead time of 12 to 18 business days, depending on volume and finish complexity.
Progress Tracking
Dedicated project managers provide weekly milestone updates, including raw material staging, processing status, and packaging photos.
Packaging & Export Logistics
International maritime transit demands rigorous packaging protocols to prevent surface oxidation, edge deformation, and scratches:
Protective Film: Laser-grade or deep-drawing PVC film (transparent, black & white, or laser-logo printed) applied to all finished faces.
Interleaving: Moisture-resistant kraft paper or pearl cotton layers between sheets to prevent frictional abrasion.
Cratting Standards: Fumigation-free export plywood boxes reinforced with steel strapping and internal corner edge protectors.
Container Loading: Forklift and overhead crane loading inside covered bays, securing coils and wooden crates with dunnage bags and heavy-duty lashing to withstand multi-modal transit (Port of Guangzhou / Shenzhen).
