Fire-resistant, long-life aluminum castings for high-speed rail, metro and light-rail interiors and exteriors.

Rail transit (high-speed rail, metro, light-rail) demands exceptional safety, lightweight and fire resistance — coupled with a 30-year service life. Aluminum castings (A356, ZL104) are produced via low-pressure or gravity casting to achieve dense, porosity-free internal structure, then inspected via 100% X-ray and fatigue tested.
All structural parts can be certified to EN 15085 or ISO 3834 (when welded), and meet EN 45545 fire-safety classes R1–R3. Surface protection is micro-arc oxidation or thick powder coating that survives 1,000-hour salt-spray. Each part ships with FAI, PPAP and third-party material reports.
Yes — we coordinate fire testing per EN 45545-2 Hazard Level HL2/HL3 through certified Chinese labs (CRRC-recognised).
