SENOTECH (OEM Accepted)
Hefei SENOTECH New Materials Co., Ltd is a professional trading company specializing in high-quality fasteners and anchoring solutions. With an annual export value of US$1 million to US$1.5 million and serving markets across North America, South America, Europe, Africa, Oceania, and Asia, we are committed to delivering reliable products for demanding infrastructure projects. Our Through Bolt for Infrastructure Projects is engineered to provide exceptional high loading capacity and long-term durability, featuring a hot dip galvanized (HDG) finish that withstands harsh environmental conditions. Available in full sizes from M12 to M36, these bolts are the ideal choice for concrete and steel anchoring in bridges, towers, highways, and heavy industrial structures.
Key Features & Technical Specifications
- High Loading Capacity: Manufactured from high-strength carbon steel (grades 4.8, 8.8, or 10.9) to ensure reliable performance under extreme loads. Each bolt is tested to meet stringent load requirements, making it suitable for critical infrastructure applications.
- Hot Dip Galvanized Finish: The HDG coating provides superior corrosion resistance. The zinc layer thickness meets ASTM A123 standards, protecting the bolt in outdoor, marine, or chemical environments for decades.
- Full Sizes Available: We offer a complete range of diameters from M12 (1/2 inch) to M36 (1-3/8 inch) and lengths from 100mm to 1000mm. Custom lengths and thread configurations (full thread, partial thread, or custom) are available upon request.
- Versatile Application: Designed for use with steel plates, anchoring concrete foundations, and connecting structural members. Ideal for bridges, transmission towers, wind turbines, highway guardrails, and heavy machinery.
- Compliance & Quality: Our through bolts are manufactured in accordance with international standards such as DIN 931/933, ASTM A325/A490, or ISO 4014/4017 (please specify your required standard). Each batch is inspected for dimensional accuracy, thread quality, and coating thickness.
- Reliable Packaging: All bolts are packed in export-grade cartons, then palletized and secured with steel strapping to prevent damage during transit. Full container loading or LCL options are available.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a through bolt and an anchor bolt?
A: A through bolt typically passes through a pre-drilled hole in a steel plate or concrete and is secured with a nut on the opposite side. An anchor bolt is embedded in concrete. Our through bolts are designed for connecting steel members or attaching to concrete using a chemical or mechanical anchor system. -
Q: Can you provide bolts with a different thread length?
A: Yes, we offer both full thread and partial thread options. Custom thread lengths are available upon request. Please specify your requirements when ordering. -
Q: Are these bolts suitable for seismic zones?
A: Yes, when using higher grades (e.g., 8.8 or 10.9) and proper installation, our through bolts can withstand dynamic loads. However, we recommend consulting with a structural engineer for specific seismic design requirements. -
Q: What packaging do you use for export?
A: Standard packaging includes inner poly bags, outer cartons, and wooden pallets. We also offer steel drums or bulk packing for large quantities. All packaging is suitable for sea freight. -
Q: Do you provide certificates of material or test reports?
A: Yes, we can provide mill test certificates (MTC) for material chemical composition and mechanical properties, as well as dimensional inspection reports. These are available upon request. -
Q: What is the typical lead time for a full container order?
A: For standard sizes, lead time is approximately 15–25 working days after confirmation of order and payment. For non-standard sizes or special finishes, please allow additional time. -
Q: Can I order samples before bulk purchase?
A: Certainly. We offer sample orders for quality evaluation. The sample cost and shipping fee can be deducted from the first bulk order. Please contact our sales team for details. -
Q: What is your warranty policy?
A: We guarantee that our products meet the agreed specifications and standards. If any defect is found due to manufacturing, we will replace or refund. Please refer to our terms and conditions for full warranty details.
