Product Precision

Thickness: The sheet’s thickness variation must meet the higher precision requirements listed in GB/T 709 table 5.

For the sheet with side trimming, the width is 0–6 mm; for the sheet without side trimming, the mill will control the width.

Profile: unflatness of sheet ≤6 mm within 1000 mm.

High deformation and straightening forces will be used to relieve the stress.

Application Features

Bridge structural steel is used in the building of highways, railroads, and transoceanic bridges. In addition to having good toughness, anti-fatigue performance, anti-corrosion weldability, and low notch sensitivity, LY Steel’s bridge steel also has a high-quality surface.

1. The steel is flat, has a well-trimmed edge, great dimension accuracy, low carbon equivalent, low diagonal deviation, and good weldability.

2. Welding testing can be performed online.

Frequently Asked Questions (FAQ): Bridge Steel

What is the difference between bridge steel and ordinary structural steel?

Bridge steel can handle the high load-bearing requirements of bridge design and retain structural integrity in adverse conditions because it is stronger, tougher, and more fatigue-resistant than regular structural steel.

Is bridge steel corrosion-resistant?

Indeed, bridge steel typically resists corrosion well, particularly in conditions with high levels of moisture or salt, as those seen in coastal regions.

Can bridge steel be used for other building structures?

Yes, viaducts, tunnel supports, and other construction structures with a high load-bearing capacity can benefit from the great strength and longevity of bridge structural steel.
