We understand that material defects, ocean corrosion, and delayed shipments can severely impact your production line. At GNEE, we eliminate these risks through advanced processing, uncompromising QC, and expert logistics.

1. Precision Slitting, Tension Leveling & Cut-to-Length
We don't just sell master coils; we provide ready-to-use materials tailored to your machines.

• High-Speed Custom Slitting: We can slit wide coils into narrow strips (down to 20mm minimum width). Our advanced rotary shear lines ensure strict width tolerances of ±0.2mm.
• Burr-Free Edges: Clean, trimmed edges guarantee that the coils won't scratch your equipment or cause edge-cracking during deep drawing and stamping.
• Tension Leveling: Our tension leveling process eliminates coil set and internal stress, ensuring absolute flatness for architectural panels and roofing sheets.

2. Custom Surface Protection
To prevent scratches during your secondary machining or transportation, we offer customizable surface protection services:

• PE/PVC Protective Film: We can apply single-sided or double-sided protective films (e.g., 50µm to 100µm thickness). Options include clear film, blue film, or laser-cutting compatible film.
• Custom Branding: We can print your company logo or processing instructions directly onto the protective film.

3. Stringent QC & Flawless Surface
Every coil is rigorously inspected in our on-site laboratory to meet ASTM/EN standards.

• X-Ray Thickness Control: Our cold rolling mills are equipped with X-ray thickness gauges to ensure uniform thickness across the entire length of the coil, strictly controlling tolerances.
• OES & Mechanical Testing: Chemical compositions are verified via Optical Emission Spectrometry (OES) before casting. Yield strength, tensile strength, and elongation are tested to guarantee accurate tempers (e.g., H14, H24, O).
• Surface Guarantee: We guarantee the surface is free from oil stains, roll marks, scratches, oxidation maculas (water spots), and corrosion.

4. Export-Grade Seaworthy Packaging
Ocean freight to Southeast Asia and the Middle East involves high humidity and extreme temperature changes. We utilize a 4-layer moisture-proof packaging system to completely prevent "white rust."

• Packaging Structure: Each coil is tightly wrapped with VCI (Vapor Corrosion Inhibitor) anti-rust paper, followed by a thick waterproof plastic film, and finally protected by hard kraft paper or corrugated board. Desiccant packets are inserted into the coil core.
• Eye-to-Sky or Eye-to-Wall: We provide both packaging orientations based on your unloading equipment (forklift or crane). Coils are strapped with heavy-duty steel bands onto fumigated wooden pallets.
• Container Lashing: We use specialized wooden bracing and chocks inside the container to prevent coils from rolling or shifting during turbulent ocean voyages.
