Frequently Asked Questions (FAQ): Bridge Steel
What is the difference between bridge steel and ordinary structural steel?
Bridge steel has higher strength, toughness, and fatigue resistance than ordinary structural steel, and can maintain structural integrity in harsh environments and meet the high load-bearing requirements of bridge design.
Is bridge steel corrosion-resistant?
Yes, bridge steel generally has good corrosion resistance, especially in environments with high moisture or salt content, such as bridge projects in coastal areas.
Can bridge steel be used for other building structures?
Yes, the high strength and durability of bridge structural steel make it also suitable for other building structures that require high load-bearing capacity, such as viaducts, tunnel supports, etc.
