Product Description

Product Description

Excellent Material & Stable Performance

It has excellent strength-to-weight ratio, corrosion resistance and thermal conductivity. The raw materials have undergone strict component and mechanical property tests, with a long service life and the ability to adapt to various complex working conditions such as humidity, acid and alkali.

High Precision Production & Interchangeability

Using CNC extrusion equipment and precision molds, the size tolerance of the profiles is controlled within 0.1mm, the surface flatness is high, and the slot size is precise. This ensures seamless compatibility with global universal accessories, and different batches of products can be completely interchangeable.

Multiple Surface Treatments

It offers various surface treatment processes such as anodizing (silver white / black / colored), sandblasting, polishing, powder coating, and electrophoretic coating. After treatment, the surface of the profiles is smooth and fine, scratch-resistant, wear-resistant, corrosion-resistant and rust-proof.
