Bridge joint: Many sizes of bridge expansion device, we can make it as your requirement.

 Bridge expansion device is a bridge annex, which mainly application in highway, railway and other projects, is a kind of devices on the protection of the bridge expansion device .

 The kind and sort of bridge expansion device

 It can be divided into six kinds according to the different body structure

 1,the type of pure rubber expansion device:

 the body structure is composed entirely of rubber (including special-shaped steel height of less than 50mm and rubber band composed of single-slit)it is used in the volume ≤50mm  

2,The type of bridge expansion device with stuffed plastic body  

 We can melt a special elastic-plastic-body rubber, in pouring among the stones

 Called “TST bridge device plastic body shell“It is suited the volume<=50mm.

 3,The type of board expansion device  

 The body structure is made by the rubber, steel or angle sulfide called for the integration of the plate expansion device, it used to the volume<60mm can’t apply to highway projects

 4,The type of Polyurethane spring telescopic device:   

 It is displace to use of the polyurethane spring and control between the beam and beam tandem installation, suited to the volume of 160 ~ 1200 telescopic device

 5,The type of combined expansion devices:  

 The expansion body structure is made by rubber plate and steel pallets which  is called

 expansion device . It used to less than 120mm expansion volume of road bridges, does not

 suited to highway bridges. For example: BF-rubber composite expansion device.

 6. The type of modulus expansion device     

 The expansion of body structure is combined by steel and rubber seal  which is suited to the volume of 0~ 80 mm 1200 highway for example the type of GQF-MZL and XF type  products.
