Benefits of Bridge Steel Plate

High strength

Bridge steel plate has high tensile strength and yield strength, which can withstand a large amount of load and deformation to ensure the safety and stability of the bridge.

Good toughness

Bridge steel plate has good toughness and impact toughness, which can keep stable and not easy to fracture when subjected to external impact or load.

Good welding performance

Bridge steel plate has good welding performance and can be welded by various welding processes, with high strength of welded joints and not easily cracked.

Good corrosion resistance

Bridge steel plate has good corrosion resistance, which can be used in harsh environmental conditions and prolong the service life of the bridge.

Application of Bridge Steel Plate

Highway bridges: Q355D steel can be used to manufacture main girders, cross girders, supporting members and other parts of highway bridges, such as suspension bridges, cable-stayed bridges, arch bridges, steel truss bridges, etc.

Railway bridges: Q355D steel can be used to manufacture main girders, cross girders, supporting members and other parts of railroad bridges, such as steel truss bridges, steel box bridges, etc.

Other bridge construction fields: Q355D steel can also be used for manufacturing urban rail transit bridges, special bridges, special bridges, etc.

Packaging and Transportation

We use standard export transportation packaging and bundle steel strips according to the size of carbon steel plates. According to our shipping experience, a 20-foot container can hold 22 tons of carbon steel, and a 40-foot container can hold 25 tons of carbon steel.

For larger orders, we use bulk carriers to transport them for you at a cheaper price. In addition, we can customize packaging according to customer needs.

FAQ

Q: What are your payment terms?

A: Our payment terms: 30% T/T deposit and 70% on B/L copy or L/C at sight, before you pay the balance. We will show you product and packaging photos.

Q: How long is your delivery time?

A: Generally, it takes 10-15 working days for stock, and 20-30 working days if there is no stock. According to the order quantity

Q: What is Q355D steel equivalent to?

A: Q355D steel material is equivalent to S355J2 steel material in European specification EN 10025-2.

Q: What is Q355B steel material?

A: Q355B steel plate is a low-alloy high-strength steel plate. Q355B steel plate has excellent mechanical function, low temperature function, and excellent plasticity and weldability. Q355B steel is used to make medium and low pressure container, oil tank, vehicle, crane, mining machinery, power station, bridge, etc.

Q: What is the difference between Q235 and Q355 steel?

A: Applications: Q235 is used where moderate strength and good weldability are sufficient, while Q355 is chosen for applications requiring higher strength, durability, and resistance to wear and tear. Cost: Q355 is typically more expensive than Q235 due to its enhanced properties and alloy content.
