Introduction

Seamless Welding Galvanized Tube Mill Machine is an equipment specialized in producing carbon steel pipes and galvanized pipes. By welding the pipe making machine with die design, the galvanized pipe can be directly and easily squeezed into pipes of different shapes, such as round, square, rectangular, special-shaped, etc. It can produce handrails, railings, tables and chairs and other pipes.

Features

Seamless Welding Galvanized Tube Mill Machine is mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, etc.
