Suzhou Suyu Railroad Material Co., Ltd.

Suzhou Suyu Railroad Material Co., Ltd. is based in Suzhou, China and currently lists five active products in its catalogue. The company focuses on railway fittings, a segment classified under HS Chapter 73 for railway or tramway track fixtures and fittings. Its product list comprises track bolts, anchor bolts, rail anchors, tie plates and rail pads, each used in the assembly and maintenance of railway track structures. The catalogue reflects a narrow but specific range of components that are integral to track stability and load distribution. These items are typically manufactured from high‑strength carbon steel to meet the mechanical demands of rail infrastructure.

The five products cover both fasteners and bearing elements. Track bolts and anchor bolts are supplied in standard metric thread sizes ranging from M12 to M30 and commonly conform to grade 8.8 or 10.9 according to ISO 898‑1. Rail anchors and tie plates are sized to match standard rail profiles such as 60 kg/m UIC 60, with dimensions specified in millimetres for length, width and thickness. Rail pads are usually fabricated from elastomeric or polymer‑filled materials, with typical thicknesses of 5 - 12 mm to provide vibration damping. All items are designed to comply with internationally recognised railway standards such as UIC 71‑3 and EN 13285.

Suzhou Suyu’s catalogue includes five distinct railway fitting components. Track bolts are high‑strength hex head bolts used to secure rails to the underlying fastening system, typically offered in lengths from 100 mm to 300 mm. Anchor bolts serve as the primary connection between the rail fastening assembly and the concrete sleeper, often provided in lengths of 150 mm to 250 mm and complying with grade 8.8 or 10.9 specifications.

Rail anchors are cast or forged steel elements that lock the rail to the sleeper, designed to match UIC 71‑3 dimensions. Tie plates are flat steel plates placed between the rail foot and the sleeper to distribute load, commonly supplied in thicknesses of 8 mm to 12 mm. Rail pads, made from rubber‑filled polymer or polyurethane, act as a resilient interface and are typically offered in sizes that correspond to standard rail foot widths, with hardness values measured in Shore A.
