Summary     

• A tooth expansion joint, also known as a fingeror comb joint, is a heavy-duty steel device usedon large bridges and roadways. It featuresinterlocking, comb-like metal teeth that slidepast each other to safely absorb bridgeexpansion and contraction caused bytemperature changes, while providing acontinuous surface for traffic..

• Cutting / welding / assembly /painting / waterproof testing

• Very high producing rate

• Professional team & exquisite workmanship

• Considerable after sale service

• Excellent dimension rate

• Very competitive price

Application 

The application of tooth expansion joints, in simple terms, refers to various high-speed highway bridges and urban elevated and expressway bridges that have high requirements for driving comfort, structural durability, and load-bearing capacity.

Features 

Smooth and comfortable driving, strong load-bearing capacity, good structural rigidity, and good durability are its outstanding advantages. Engineering practice also tends to adopt a new type of comb plate structure with integral anchoring and bolt free, in order to solve the pain points of traditional bolt connected comb plates that are prone to loosening and require frequent replacement, further extending their service life.
