How to choose?

Please find the right model according to the maximum bending sectional modulus of profiles in the following parameter table.

The main parameters on form means the max. bending capacity with best working efficiency. If other steel profile like square, angle, only if the bending sectional modulus less than 75 cm3, then it is available to finish bending on this 75.learn more: What is the section modulus

You can also choose the required model according to the bending material:Square Bar (square steel), Round Bar, Flat Bar (flat steel), Equal Angle, Unequal Angle, Tees, channel steel , H & I Beams , Round Tube , Square Tube

The Section Bending Machine is a special equipment specially designed for bending and forming of profiles. It can bend metal profiles such as angle steel, flat steel, channel steel, steel pipe, profiled steel, etc. into a cylindrical shape without changing the cross-section characteristics. Or spiral workpiece.

Depending upon your unique project requirements, Profile Bending angle bending may be performed on a variety of materials, including carbon steel, stainless steel, aluminum, titanium, and copper.

BIT section bending machine is designed for bending all types of profiles, Our Angle Roller ( Profile Bending Machine ) only needs one set of assembly mould, can bending angle steel, channel steel, flat steel, square steel, square tube, U type, I type, T type, L type , flat and round profiles and pipes, this type of machine can handle a variety of special parts.

Glossary of common bending-rolling

With the international advanced technology, programmable digital control by PLC, all hydraulic drive. This series section bender dedicated to the small straight adge and high precision bending design, profile bending roll feeding can finish by one time for pre-bending section, roll and inspected. Its structure is advanced, short bending straight edge, high precision bending profiles.


• Reasonable weighted host

The main frame of all BIT section bending machines is welded.

Machining and wire drilling steel structures using the heaviest components of any type of machine to increase strength and stiffness and eliminate frame stress design.

 • Maximum shaft diameter and bearing size

The roll shaft is made of high-strength chrome-nickel alloy steel and is the largest diameter shaft of any type of machine. Rolling tools use super-large roller bearings for increased efficiency and longer life. The standard tool is a combination kit for bending and bending, flat bars on the plane and edges, T-bar cutting and cutting in and down, small square bars and even small solid round bars. Usually, no extra gaskets are needed.

• Highest drive torque and speed

The BIT profile bending machine offers the largest drive torque in any class of machine. A larger drive torque means that the profile can usually be rolled with fewer passes, which usually results in less deformation of the profile being rolled. Always drive all three rolls. All models typically have a speed of 7 m / min and are more functional than other similar machines.

• Maximum bending roller force

The two lower rollers are individually adjusted by a hydraulic cylinder. The size of the rolls allows the BIT profile press to produce a greater bending force than any similar machine, providing maximum profile modulus.

• The most powerful guide roller

The BIT profile bending machine has the largest and most powerful guide roller on the market. In this way, they can stand out from the most promising parts of the machine's capabilities. Each model comes standard with hardened steel guide rolls, including “leg-type” guide rolls.
