The performance record of our specially designed and manufactured automatic welding machine is the backbone of Friendship Machinery's reputation. The proven ability of every set machine is why customers have returned to us repeatedly for new applications, designs and machinery as their products change and expand. We are proud of that fact.
Our main products: H&I beam welding line, T beam welding line, box column beam line, CNC multi-head plate cutting line, beam assembly machine, straightening equipment, steel pipe welding line, shot blasting machine, CNC flame/plasma cutting equipment, welding assisting machinery incl. Welding manipulator, welding positioner, turning roll (welding rotator), Membrane wall panel production line, which are widely used in many industries like aerospace, petrochemical, metallurgy, shipbuilding, chemical equipment, boiler pressure vessels, steel structure construction, etc.
Since 1990s, the market for steel structure building industry boomed. With fast development, very short period for construction and beautiful external appearance, as well reasonable price was occupied in the market of building industry. We invest more on developing roll forming machine such as Metal roof &wall panels machines, C&Z purlin machines drywall Stud-track forming machines , Metal decks machines , No- girder and Column curves forming machines, Guard rails forming machines , Downspout pipes forming machines and so on.
