Import Fish Bolt — Buy in Bulk from Supplier in China

The fish bolt offered by Suyu Railway Materials Co., Ltd. is manufactured from carbon steel grades Q235, 35K and 45#, providing a range of mechanical properties for heavy‑duty fastening. It is supplied in two neck configurations - an elliptical neck and an oval neck - each engineered to spread load across the fastening point. All bolts receive a surface treatment that improves corrosion resistance for outdoor and industrial use.

Q235 and the higher‑strength 35K and 45# grades are widely used in railway and construction applications, typically delivering tensile strengths between 370 MPa and 550 MPa depending on the exact grade. The elliptical and oval neck profiles help to minimise stress concentration, a design feature common in track bolts that must endure dynamic loads. Standard industry practice adds a zinc or hot‑dip coating, giving a corrosion resistance class of 3 as defined by ISO 12944‑2, which suits the harsh environments encountered in rail infrastructure.

Typical buyers include rail network contractors, heavy‑equipment manufacturers and large‑scale construction firms that require reliable track fastening solutions. The supplier mentions flexible minimum order quantities, but the precise MOQ and lead‑time are not disclosed and should be validated with the seller. Accepted payment methods include T/T and L/C, and shipping can be arranged under FOB or CIF terms depending on the buyer’s preference.

Suyu Railway Materials Co., Ltd. is based at Tonghu Road No. 588, Suqian, Jiangsu Province, China. The company is recorded as an imported supplier with a harbor trust tier, signalling that it has satisfied basic verification requirements on the platform. Its response rate is shown as 0 % and no average response time is provided, indicating that communication through the listing may be limited.

The firm specialises in railway‑related materials, with a catalogue that includes fish bolts, rail clips and other fastening components. The current listing does not disclose specific MOQ, price, or lead‑time figures, so prospective buyers must request those details directly from the supplier. No explicit quality certifications are attached, therefore buyers should ask for ISO or other relevant certificates during the negotiation process.
