GB/T30060 Pipe Fittings Applications
- High-speed railway bridges – Ideal for long-span and high-load-bearing bridges under dynamic loading conditions.
- Urban rail transit systems – Suitable for elevated metro and light rail structures demanding excellent fatigue resistance.
- Highway and overpass bridges – Especially in coastal or mountainous regions where anti-corrosion properties are essential.
- Heavy-duty transportation structures – Used in large-scale cross-river and sea-crossing bridges requiring ultra-high strength (such as Q390PF, Q485PF, or Q555PF).
- Special engineering bridges – Applied in cable-stayed or suspension bridges facing high wind and seismic loads.
