Railway & Transit
Subway and high-speed rail trains vibrate continuously in service, and a loosened catenary or track fastener is a direct safety hazard — railway fasteners must resist vibration fatigue, stay traceable and be easy to maintain. JIALI supplies 10.9 / 12.9 grade high-strength bolts, nylon-insert and flange lock nuts, 304 / 316 stainless steel and Dacromet-coated parts with loosening marks and batch traceability, meeting ISO 898-1 and railway-industry quality requirements — a reliable Hong Kong supplier of railway fasteners supporting drawing-based custom and batch supply.
