Quzhou Aoyin Metal Materials Co. Ltd
Quzhou Aoyin Metal Materials Co. Ltd was established in Quzhou in 2019, and our team has been in aluminum processing since 2007. Export processing and delivery is the main business. We ship from the mills buyers visit with us — melting and casting through rolling, finishing and packing, every station open to inspection. Cutting, levelling, slitting and export packing happen on our own floor, and every order is released against one acceptance standard and shipped under our name.
Our main products include aluminium sheet, strip, coil, foil and profile, with plate as the core line and profile as the complement. Annual volume is 5,000+ tonnes, shipped on repeat export programs. The range covers nearly all 1-8 series aluminium alloys, especially 1xxx, 3xxx, 5xxx and 8xxx, shipped into silo and tank shells, shelter and container panels, road tankers and ISO tank containers, marine hulls and decks, and HVAC and cold-chain panels.
We work as a project-based supplier. An order here is a list of specs: alloy, temper, gauge, width and length follow the customer’s project list, and the material is cut, kitted and shipped as one order — whether it comes off the standing stock or a rolling slot.
What we make
Six product lines, all cut to the project list before packing. Plate 3–50 mm and sheet 0.2–3 mm run as separate routes.
Aluminum plate
3–50 mm, width 2,000 mm routine and 2,200 or 2,400 mm to order. 5083, 5754, 5052 and 6061 carry most of the tonnage.
Aluminum sheet
0.2–6 mm in 1050, 3003 and 5052, with 1050 H14 and 5052 H32 as the routine tempers.
Aluminum coil & strip
3003 and 5052 coil for shelters, cladding and HVAC, slit to width on the same route.
Tread & embossed
Tread plate and stucco embossed sheet for flooring, toolboxes and cold-room panels.
Marine grades
5083 H116 and H321 plate for hulls and superstructures, shipped under our marine brand Delin Aluminum.
Extruded profiles
6063, 6061 and 6005A extrusions as the complement line, including battery enclosures on ayaluminum.com.
Main project lines today: silos and tanks, shelters and container bodies, road tankers and tank containers, marine and offshore, HVAC and cold-chain panels. Battery enclosures and ESS housings run through ayaluminum.com.
Built to the project spec
- Cut to the project list: lengths and widths follow the customer’s cutting list, kitted per project before packing
- Every order is produced to the project spec and released against one acceptance standard, shipped under our name with our MTC pack
- No MOQ on project specs; stock and standard sizes start from 3 tonnes
- One order leaves as one kit: one MTC pack, one packing list, one container plan
A mixed order of several alloys and gauges is normal here. Send the full list and we confirm which lines run on the current program and which need a rolling slot, before you commit.
Quality control
- Mill test certificate per heat, with chemical composition and mechanical properties reported per thickness band
- Gauge, width and flatness measured before cutting, confirmed against the customer’s cutting list
- SGS, TÜV and BV inspectors booked into the same schedule as our own QC; mill audits welcome year-round
Export packing and delivery
- Seaworthy packing on ISPM 15 heat-treated timber pallets, 2.5–3.5 tonnes per pallet
- 20GP and 40HQ containers loaded to plan, 25–35 days from order confirmation to vessel
- Documents per shipment: MTC per heat, packing list keyed to the cutting list, and the container plan
- Heat numbers traceable back to the cast
What the stock actually looks like
Every photo below was taken on the floor we walk buyers through, not bought from a library. Alloy, temper and size stay stencilled on the plate from release through to the container, so any plate can be traced back to its heat.
Group brands
Both are AOYIN product lines: marine plate ships under the Delin brand, battery enclosures under ayaluminum.com.
Delin Aluminum
Delin Aluminum is our marine-grade brand: 5083, 5086 and 5052 plate and sheet for shipbuilding and offshore, produced on the same lines and released against the same acceptance standard.
dlaluminumplate.com →AOYIN battery enclosures
Extruded aluminum cases, trays and cabinet bodies for e-rickshaw, e-scooter and stationary storage programs. Extrusion and anodizing run on the lines in our production network with tooling owned by AOYIN; CNC machining runs in our own workshop. Every stage is open for your audit.
ayaluminum.com →Common questions
Can we audit the mill before placing an order?
Yes. Audits are welcome year-round and take about half a day: casting, rolling, heat treatment, finishing and packing. Buyers who cannot travel get a live video walk-through on the same route.
Do you work with our third-party inspector?
SGS, TÜV and BV inspectors are booked into our own QC schedule. Inspection is quoted as a line item, and the pallets stay on hold until your inspector releases them.
What documents come with each shipment?
A mill test certificate per heat, a packing list keyed to your cutting list, and the container plan. Heat numbers are traceable back to the cast.
How long does a first order take?
25–35 days from order confirmation to vessel for standard gauges and tempers, shorter where the gauge is in stock. Rush slots are confirmed against the production plan before we quote a date.
