Fabrication Process
Aluminum extruded fin tubes is formed from a bi-metallic tube. Consisting of an aluminum outer core and an parent tube of almost any material. The fin is formed by rolling material from  the outside of the exterior tube to give an integral fin. The extruded fin is manufactured by compressing an aluminum outer core tube onto the parent tube. The outer core tube is exposed to extremely high pressures which essentially "grows" the fins into the final fin profile. Maximum operating temperature for this fin type is 290℃.

Production Capacity
Total eight bi-metallic finning lines, monthly production capacity is 160000 meters in total.

Codes and Standards
As per drawings and client's Requirements

Surface Treatment and Protection
Each tube will be cleaned free of rust, grease, residues or any other contaminants before extruding.
