Our Workshop

All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland)

1+1+4 hot rolling mills and 1+5 hot rolling mills from SMS Group (Germany).

6 sets of cold rolling mills from SMS Group (Germany) ......

1) We introduced a wide range of world-class equipments to ensure product quality.

2) We specialize in high-quality aluminum alloy coils, with key grades such as 1050, 1060,

1100, 3003, 3004, 3104, 5052 and 6061.

3) We follow clear internal management and standardized processes to keep our production

smooth, efficient, and well-organized.

Automatic Aluminum Coil Wrapping Machine

1) Less manual work, faster and easier packaging.

2) Accurate control for neat, consistent wrapping every time.

3) Tightly wrapped coils stay secure and are easy to transport.

All Automatic Three-dimensional Elevated Warehouse

♦ Smart Storage: it can automatically handles high-temperature coils from hot and cold rolling,

monitoring their temperature at the same time.

♦ Automated Transport: automated coil transport cars smoothly plan their routes based on

production needs.

♦ Flexible Handling: all the coils are efficiently and flexibly delivered to the next production stage.

Alloy Ingot Storage Area

This area is used to store different types of alloy ingots.

Materials are neatly stacked for easy tracing and handling, ready for use before rolling.

Ocean Shipping

1) We use cushioning materials between the coil and wall, and tighten everything with specialized

lashing straps.

2) we place non-slip wooden blocks under each coil to prevent any movement during the shipping.

3) It has the waterproof layer inside the package, we also put many desiccants in the container,

to protect the cargo from moisture
