Hangzhou Fintube Co.,Ltd

Hangzhou Fin Tube Co., Ltd. (HZFT) is an international finned tube manufacturer based in Hangzhou, China, focused on the R&D, manufacturing, and product extension of integrated finned tubes. Established in 2006, the company has built long-term expertise in shaping integral finned tube solutions for demanding heat transfer applications.

HZFT develops two core process routes. Its extruded finned tubes are produced on soft materials such as copper and cupronickel, with fins roll-formed from the outer surface of a plain tube to eliminate contact thermal resistance and support efficient heat transfer, durability, and vibration resistance. For materials such as stainless steel and titanium, HZFT produces laser-welded finned tubes, using instantaneous strip welding to create a tight bond between fin and tube for strong, efficient heat exchange.

With 19 finned tube production lines and an annual capacity of 1.7 million meters, HZFT serves both domestic and international markets. More than 70% of its sales are to overseas customers, including brands such as Raypak, Pentair Pool, Zodiac Pool, Astral Australia Pool, A.O. Smith, and RBI. In 2017, the company was assessed as a state-level high-tech enterprise.
