New Finger Joint X-Type (NFJ-X)
 






- The NFJ X-Type waterproof system adopts a dual structure to prevent ingress of alien substances and has a waterproof sheet. It is designed to simultaneously resolve the existing problems of a finger - alien substances and water leakages.

- It is shipped as the final product from the factory. Its torque on bolts and welding qualities are great.

- It uses steel materials of high durability. It can support a semi-permanent lifetime.

- The alien substance prevention waterproofing material can push away alien substances from the finger when contracted. So, it does not require periodic cleaning.

- The waterproof device is made of synthetic rubber with excellent anti-ozone and freezing features and durability. It can prevent damage to the waterproof material even when alien substances are accumulated or the load is generated.

- It is a continuous finger-to-finger structure that is less vulnerable to noise and impact.

- No spaces exists between the structures. It has excellent waterproofing ability. It is a low-noise type finger that can absorb noise and impact even when excessive rotation generates uneven levels or unequal sagging takes place.





The NFJ X-Type waterproof system adopts a dual structure to prevent ingress of alien substances and has a waterproof sheet.

It is designed to simultaneously resolve the existing problems of a finger - alien substances and water leakage.






It is shipped as the complete product from the factory. Its torque on bolts and welding qualities are great.







It uses steel materials of high durability. It can support a semi-permanent lifetime.







It is a continuous finger-to-finger structure that is less vulnerable to noise and impact.





After alien substances are accumulated, shrunken intervals or moving vehicles can cause damage to the waterproof sheet. To prevent such damage, this alien substance prevention waterproof material made of high-quality elastomeric rubber is applied. It can offer high reliability for the long lifetime of the waterproof sheet.







The alien substance prevention waterproofing material can push away alien substances from the finger when contracted. So, it does not require periodic cleaning.





It is shipped as the final product from the factory. So it can reduce the time for installation and achieve a high degree of completion.
