Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer established in 1998 with annual export values between US$5 million and US$10 million. Our Railway Sleeper Dowel Pin 12mm Diameter 180mm Length Zinc Plated Carbon Steel is engineered to provide reliable fastening solutions for railway track systems. With decades of experience in hardware production, we combine precision manufacturing, durable materials, and cost-effective pricing to meet the demands of global railway maintenance and construction projects.
This dowel pin is specifically designed for fixing railway sleepers (ties) to the track bed, ensuring stable alignment and long-term performance under heavy loads. The 12mm diameter and 180mm length offer optimal shear strength and holding power, while the zinc-plated carbon steel construction resists corrosion in outdoor environments. Our product is widely used in North America, South America, Europe, Southeast Asia, Africa, and Oceania, serving railway contractors, infrastructure companies, and maintenance teams.
Below we provide detailed specifications, advantages, and answers to common questions to help you make an informed purchasing decision.
Key Features & Benefits
- Precision Dimensions: 12mm diameter and 180mm length with tight tolerances (±0.2mm) ensure consistent fit into sleeper holes and rail clips.
- High-Strength Carbon Steel: Made from quality carbon steel (e.g., Q235 or equivalent) for excellent tensile strength and impact resistance, capable of withstanding dynamic railway loads.
- Zinc Plated Finish: Hot-dip or electro-galvanized zinc coating provides effective corrosion protection, extending service life in humid, rainy, or coastal environments.
- Easy Installation: Smooth surface and chamfered ends reduce friction during insertion, speeding up track assembly and maintenance.
- Versatile Application: Compatible with standard railway sleeper systems, including wooden, concrete, and composite ties, as well as various rail fastening assemblies.
- Cost-Effective: Factory-direct pricing with no middleman markup, allowing you to procure high-quality pins at competitive rates.
- Customizable Options: Available in different lengths, diameters, materials (e.g., stainless steel), and surface treatments (e.g., hot-dip galvanized, plain) upon request.

Detailed Product Description
The Railway Sleeper Dowel Pin is a critical component in modern railway track systems. It is used to secure the sleeper (tie) to the rail base or fastening system, preventing lateral movement and maintaining track gauge. Our 12mm diameter, 180mm length pins are manufactured from high-quality carbon steel, which offers an excellent balance of strength, ductility, and wear resistance. The zinc plating process creates a protective layer that shields the steel from moisture, oxygen, and chemicals, significantly reducing the risk of rust and extending the pin's lifecycle in harsh outdoor conditions.
Each pin undergoes strict quality control during production: raw material inspection, dimensional measurement, surface finish check, and salt spray testing (upon request) to ensure the coating meets required standards. Our factory, located in Hengshui, Hebei, China, has been producing hardware wiremesh products since 1998, and we have developed a robust supply chain that allows us to deliver large orders efficiently. We ship from major ports including Tianjin, Qingdao, Shanghai, and Foshan, covering global markets.
Compared to ordinary steel pins, our zinc-plated version offers better corrosion resistance, which is especially important for railway projects in coastal areas, tunnels, or regions with high rainfall. The 12mm diameter is a common standard for many rail systems, ensuring compatibility with existing components. The 180mm length provides enough engagement depth to ensure a secure hold without excessive protrusion, reducing the risk of snagging or damage during maintenance.
We also offer customization: if you need a different length (e.g., 150mm, 200mm) or diameter (e.g., 10mm, 14mm), or if you prefer a different material such as stainless steel (304, 316), please contact us. Minimum order quantities are flexible, and we can provide samples for evaluation before bulk production.

Frequently Asked Questions (FAQ)
-
Q: What is the tolerance on the diameter and length?
A: Our standard tolerance is ±0.2 mm for diameter and ±1 mm for length. Tighter tolerances are available upon request. -
Q: Can you provide a material certificate or test report?
A: Yes, we can issue a mill test certificate for the carbon steel material and a coating thickness report for the zinc plating. Please specify at the time of order. -
Q: Is the zinc plating suitable for outdoor railway use?
A: Yes, the zinc plating provides good corrosion resistance for outdoor environments. For more aggressive conditions (e.g., coastal or chemical exposure), we recommend hot-dip galvanized or stainless steel options. -
Q: What is the typical lead time?
A: For standard sizes (12x180mm), lead time is 7-15 days after order confirmation, depending on quantity. Custom sizes may take 15-25 days. -
Q: Do you offer samples? Are they free?
A: Yes, we provide samples. For small quantities, you may need to pay the shipping cost. The sample itself is free for standard items. Contact us for details. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard dowel pins is 5,000 pieces. For non-standard sizes or materials, it may be higher. We can be flexible for trial orders. -
Q: How are the pins packaged to prevent damage during shipping?
A: They are packed in strong cartons, then palletized and wrapped with stretch film. For large orders, we can also use wooden crates or steel drums as per your request. -
Q: Can you produce pins with a different diameter or length?
A: Yes, we offer customization. Common sizes include 10mm, 14mm, 16mm diameters and lengths from 100mm to 250mm. Please provide your drawing or specifications.
