Import Anchor Bolts — Buy in Bulk from Supplier in China

Anchor bolts from Suzhou Suyu Railroad Material Co., Ltd. are precision-engineered for permanent fixation into concrete and masonry, with grades spanning 4.6 to 12.9 to match diverse load requirements. The supplier offers finishes including plain, black, zinc, and hot-dip galvanised, ensuring compatibility with indoor and outdoor environments. Custom configurations are produced to buyer drawings or samples, covering special bolts, U bolts, foundation bolts, stud bolts, rod bolts, curved bolts, and tunnel bolts.

The bolts are typically manufactured from low to high-strength carbon steel, with grade 8.8 and 10.9 variants providing tensile strengths of 800 MPa and 1000 MPa respectively, standard for structural applications. Surface treatments like zinc plating add corrosion resistance, with a typical coating thickness of 5 to 15 microns for standard applications. Common thread standards include ISO metric coarse and fine pitches, with typical tolerances adhering to ISO 724 for threads and ISO 2768 for dimensional accuracy.

These anchor bolts are used in railway infrastructure, industrial machinery anchoring, and construction projects where vibration resistance and static load capacity are critical. Buyers typically source these for bridges, wind turbines, and heavy equipment foundations, with packaging and marking tailored to project specifications. The supplier’s location in Suzhou, Jiangsu province, provides logistical access to major Chinese ports for bulk exports.

Suzhou Suyu Railroad Material Co., Ltd. operates from No.8, Rubang Road, Changshu, in Suzhou’s industrial district, with a focus on railroad and structural fasteners. The company’s product range includes anchor bolts alongside other specialty fasteners, catering to infrastructure and heavy machinery sectors. Its classification as an imported-tier supplier indicates experience in cross-border trade, though its current response rate and average response hours are not publicly tracked.

The supplier does not disclose certifications, production capacity, or client references in the available data. Buyers should verify compliance with relevant standards such as ISO 4014 for hex head bolts or ASTM F1554 for anchor bolts, as these are typical benchmarks for structural applications. The absence of published response metrics suggests direct outreach may be necessary for technical clarification or customisation requests.
