CAD Engineering & Custom Profile Design Verification

Translating complex design concepts into high-precision, functional metal components is our specialty. Our in-house engineering team works directly with your R&D department to review and verify custom drawings in DWG, DXF, and PDF formats. From calculating the strict dimensions of a custom pentagonal wire for eyewear frames to evaluating the slot-gap load-bearing limits of a heavy-duty rotary drum screen, we ensure every tolerance, radius, and mechanical requirement is fully optimized before tooling production begins.

Certified Quality Assurance & Full Metallurgical Traceability

At Jingzhou Metal, raw material integrity is verified through strict quality documentation. Every production batch of our stainless steel, titanium, and nickel alloy wires undergoes rigorous metallurgical analysis, including chemical composition checks, tensile testing, and optical projector dimension measurements. To ensure complete traceability across your supply chain, we supply certified Mill Test Reports (MTR/MTC) conforming to international standards with every shipment. Copies of our ISO 9001 certificates are also available upon request.

Robust Export Packaging & Global Logistics Execution

Long-distance ocean freight demands packaging standards that eliminate damage and rust. We pack our wire spools, coils, and straight-cut rods in heavy-duty, fumigation-free wooden crates and boxes. All metal materials are wrapped in vacuum-sealed, moisture-proof plastic film with silica-gel desiccants to prevent any saltwater corrosion or oxidation during transit. We coordinate closely with leading global freight forwarders to handle FOB, CIF, or DDP logistics, ensuring seamless delivery to major European and North American ports.

Frequently Asked Questions

Find answers to common questions about our products, customization, and delivery.

We accept and review all industry-standard CAD formats, including DWG, DXF, and PDF. Our engineering team can work directly from your technical blueprints or physical samples to verify dimensions, tolerance limits, and alloy suitability before producing custom drawing dies or screen tooling.
Yes. Every shipment of our custom shaped wire, precision round wire, and wedge wire screens includes a comprehensive Mill Test Report (MTR/MTC). These reports certify chemical composition, tensile strength, yield strength, elongation, and precise dimensional compliance to ensure absolute traceability and quality assurance.
We provide free samples for in-stock standard specifications of round and shaped wires. For non-standard custom profiles requiring dedicated drawing dies or specialized screen tooling, we charge a reasonable tooling fee. This tooling fee is fully refundable or deductible from your subsequent high-volume production orders.
