Bridge Steel Grade

Bridge steel plate is a special thick steel plate for manufacturing bridge structural parts. It is made of carbon steel and low alloy steel for bridge construction.

Description

A special steel used in bridge construction, bridge steel grades is a type of steel usually produced from high-strength steel, which has excellent advantages of high strength, excellent strength-to-weight ratio, wear resistance and corrosion resistance, so it is widely used in the construction of various bridges.


I. the Common Problems in the Use of Bridge Steel Grade 


1.Corrosion: Bridge steel grades are often in a wet environment and are prone to corrosion, resulting in a decrease in the strength of the plates and affecting the safety performance of the bridge.


2. Fatigue: In long-term use, bridge steel grades are subject to constant loading, which can easily lead to fatigue damage, affecting the service life and safety performance of the bridge.


3. Levelness of the bridge deck: the way the bridge steel grades are connected and paved will affect the levelness of the bridge deck, affecting the comfort and safety of the traffic.


4. Anti-slip performance: The anti-slip performance of the bridge steel grades surface has a great impact on the safety of driving, if the anti-slip performance is insufficient, it will easily lead to vehicle skidding, loss of control and other situations.
