Industrial Applications
Extruded aluminum profiles and CNC machining are ideal solutions for a wide range of industries. We supply aluminum profiles to the construction, electronics, automotive, and other industries.
Aluminum profiles combine high strength, design flexibility, and corrosion resistance, making them ideal for use in partitions, exterior walls, curtain walls, roofs, and structural frames.
Aluminum door and window frames are widely popular in the construction industry due to their durability, design flexibility, light weight, and corrosion resistance.
Aluminum profiles are commonly used in the manufacture of glass wine cabinets, wardrobes, and modular systems, as they are lightweight yet highly durable.
The aluminum profiles used in the bumpers, roof, roof rails, and chassis help reduce the vehicle’s weight while maintaining strength, thereby improving fuel efficiency and crash safety.
Aluminum profiles are an ideal choice for manufacturing machine frames, linear guides, and robotic arms, offering high precision, modularity, and lightweight durability in automated systems.
Aluminum profiles are lightweight, strong, and corrosion-resistant, making them widely used in renewable energy systems such as solar mounting structures, wind turbines, and protective enclosures.
Aluminum profiles can be customized into specialized architectural and furniture profiles, offering design flexibility for industrial projects while combining strength, precision, and aesthetic appeal.

The lead time for bulk orders is 20–25 days. Whether you choose EXW, FOB, CIF, or DDU, we can provide shipping cost estimates for your reference.
What is the minimum order quantity?
For aluminum profiles requiring custom extrusion dies, we do not impose a minimum order quantity, and generally, the larger the batch size, the lower the unit price. We will also provide samples of specific lengths for your approval. Once die testing is complete, we will make modifications free of charge based on your feedback on the samples.
