The double inner crimping C-channel steel can meet the firm characteristics of the top structure in the operation of the support system on both sides of the steel, and can prevent the rotation and circulation blockage in the different corner code conversion equipment. Therefore, the function of convenient movement in the gear support with perfect structure has become the structural feature of the building support steel which can resist the firm use.

The first point: the anti-corrosion function: the double inner curling C-channel steel bears the effect of convenient movement in the rotation function of polygon in the running characteristics of the steel pipe supported at the bottom. The impact performance is firm in the support function of various installation parts, and it is not suitable to fall off in the impact of rainstorm, and the paint on the surface is easy to rust.

The second point: the strong sliding support characteristics of the accessory mechanism: for the movement of the use position of the electric energy control system, it can protect the phenomenon of stable impact flow and unsuitable sliding in the functional use of the electric control parts, which has become the automatic contraction characteristics in the transport bearing connection of the firm belt rotation.

The third point: reduce the support assembly support capacity: with the use of the support power of the building, it can improve the function of the stable installation of the main materials in the molding use, impact firmly and stably in the different sliding support cement structures, and achieve the leveling performance of a variety of pressing processes and the effect of stable installation of the mechanism.
