Square Rectangular Steel Pipe Mill Machine Directly To Square
“Directly to Square” forming Technology
Directly roll steel strip and form into Square& Rectangle, weld and then turks head to get finished pipes. One complete set of combined rollers can make all the square and rectangular pipes, is economical and practical. The roll forming process takes square or rectangular pipes as one package of profiles between each other automatically adjusted by one set of combined rollers.
Directly to Square advantages:
