The importance of the choice of materials

                                  

The material of frame straightening machine is very important ,it will determine the price. The matrial usually divided into ordinary steel, and 16 manganese steel.

You know the ordinary steel is belong to Q235,such as material of 14# I-beam is hot-rolled carbon , withstand strenghth is 235 . Another material is Rectangle tube, 

It also is a ordinary material.  

We also have a manganese steel material, just ordinary steel elements add alloy manganese elements, so it  increase the strength and hardness of the plateform.

This cause the portable frame machine of manganese steel material is more better than other material, including the I-Beam and rectangular tube.

And the welding complex, I-Beam and Rectangle tube is the whole steel welded directly molded on it, but the manganese steel is on the up and down two 10mm thick intermediate plate stiffener welding , 

So please understand the material of car bench,welding process, welding method firstly.

We think the price is not very important , you need pay a special attention to the quality of  car frame machine that you want to buy.
