Our Quality Control System: Full-Process Inspection from Raw Materials to Finished Products
We have established a comprehensive quality control system covering the entire product lifecycle. At the raw material stage, each batch of aluminum ingots must provide material certificates and undergo spectrometer analysis to verify composition. During extrusion, online detection systems continuously monitor dimensional tolerances and surface quality to ensure profile straightness and wall thickness uniformity.
Precision machining utilizes CMM for full-dimension inspection, with key fitting dimensions controlled within ±0.05mm. Surface treatment phases employ coating thickness gauges and colorimeters to verify finish quality, while salt spray testing validates corrosion resistance. All inspection data is recorded in real-time, enabling complete traceability.
We strictly implement the ISO9001 quality management system, ensuring every batch is accompanied by inspection reports for your complete confidence in received products.
A square aluminum tube is a hollow aluminum profile with a square cross-section designed for automotive structures and components. It provides lightweight strength, corrosion resistance, and excellent structural performance for vehicle manufacturing.
Square aluminum tubes are widely used in:
Vehicle frames
Electric vehicle structures
Truck bodies
Roof racks
Chassis components
Battery enclosures
Automotive interior supports
Trailer and caravan frames
We commonly supply automotive aluminum tubes in:
6061 aluminum alloy
6063 aluminum alloy
6082 aluminum alloy
