Processing Overview
Foshan Winton Stainless operates a 67,000-square-meter manufacturing facility featuring 39 dedicated production lines. We integrate the entire stainless steel processing chain-from precision slitting and mechanical leveling to vacuum PVD coating and anti-fingerprint treatment.
By consolidating mechanical fabrication, surface texturing, and chemical finishing under one roof, we eliminate multi-vendor handoffs. This integrated workflow secures strict batch-to-batch consistency, tight dimensional tolerances, and reliable lead times for global architectural and industrial projects.
Available Processing Services
Our facility is configured for both high-volume industrial coil processing and fine architectural customization. Core services include:
Precision Slitting & Cut-to-Length: Automated leveling and shearing lines process coils into exact sheet dimensions with controlled edge camber.
Fiber Laser Cutting & CNC Punching: High-speed laser systems deliver clean, burr-free cuts on complex geometric profiles and structural components.
Bending & Press Brake Forming: Multi-axis CNC press brakes execute precise angle bending for channels, tile trims, and facade profiles.
Industrial Degreasing & Chemical Cleaning: Dedicated cleaning lines remove rolling oils and surface residues prior to PVD coating or mechanical finishing.
Surface Finishing Options
Surface texture and visual uniformity are critical for architectural specifications. We offer a comprehensive suite of mechanical and chemical finishes:
Mechanical Finishes
No. 4 / Hairline (HL): Directional fine-grit polish with controlled Ra roughness values for elevator interiors and architectural cladding.
Mirror (No. 8): Multi-stage abrasive polishing delivering high-clarity, distortion-free reflective surfaces.
Bead Blasted / Satin: Uniform matte textures achieved via controlled media impact.
Color & Protective Finishes
PVD (Physical Vapor Deposition): Titanium-based coating options include Gold, Rose Gold, Champagne, Black, Bronze, and Sapphire Blue with strong UV and wear resistance.
AFP (Anti-Fingerprint Coating): Nano-clear protective layer resisting oils, smudges, and corrosion while maintaining tactile and visual neutrality.
Customization Options
We engineer processing parameters to match specific project blueprints and engineering requirements:
Dimensional Customization
Non-standard thicknesses, customized sheet lengths up to 6000mm, and slit widths tailored to fabrication lines.
Profile Fabrication
Custom stainless steel tile trims, U-channels, Z-profiles, and perforated acoustic panels.
Grade Substitution & Matching
Technical support for matching existing architectural samples or upgrading alloy grades for corrosive environments.
Material & Technical Specifications
Available Steel Grades:
- Austenitic: AISI 304, 304L, 316, 316L, 321
- Ferritic & Others: AISI 430, 201 (upon request)
Thickness Range:
- Cold Rolled: 0.3mm to 3.0mm

Standard Sheet Sizes: 1000mm x 2000mm, 1219mm x 2438mm (4x8ft), 1219mm x 3048mm (10ft), 1500mm x 3000mm (custom coil-to-length available).
PVD Color Tolerance: Controlled spectrophotometer Delta E (dE) values under 0.8 to ensure zero visible color variance across large-scale facade installations.
Processing Workflow
Our standardized manufacturing sequence ensures complete traceability from raw material intake to final export crating:
Raw Material Inspection
Incoming coils undergo thickness gauging, surface defect checks, and PMI (Positive Material Identification) testing.
01
Primary Mechanical Processing
Material passes through leveling, slitting, or laser cutting according to shop drawings.
02
Surface Treatment & Texturing
Mechanical polishing, bead blasting, or chemical cleaning executed in dedicated clean zones.
03
PVD & AFP Application
Vacuum chamber deposition for color coating, followed immediately by anti-fingerprint curing and protective laser-film lamination.
04
Packaging & Protection
Interleaving paper/foam protection, PVC laser film application, and export-grade wooden crating.
05
Quality Inspection
We maintain strict quality control protocols backed by ISO 9001:2015 certification:
Dimensional Verification
Digital calipers, micrometers, and laser-based flatness meters.
Surface & Color Audit
Spectrophotometers for color consistency and visual inspection under standardized 6500K light boxes.
Mechanical & Coating Testing
Cross-hatch adhesion testing for PVD/AFP coatings, salt spray corrosion testing (ASTM B117), and coating thickness gauge verification.
Documentation
Mill Test Certificates (MTC) supplied in accordance with EN 10204 3.1 for every production batch.
OEM & Custom Orders
We support international OEMs and large-scale contractors through scalable project execution:
Engineering Support: CAD/CAM file review, shop drawing optimization, and sample prototyping prior to mass production.
Batch Scalability: Capable of handling small-batch custom architectural runs alongside high-volume industrial coil processing.
Logistics & Protection: Customized export packaging designed to withstand multi-mode ocean freight and prevent transit scratching.
