Highway Barrier Pins
Connecting Pins
Barrier pins are used to connect precast concrete highway barriers together. Portland Bolt's approved head design allows for easy removal without the need for special tools.
Stabilization Pins
In some states, high strength pins get driven through the base of precast concrete barriers in order to pin them to the ground. Base pins are usually made from high strength steel, hot-dipped galvanized with a semi cone point. Appropriate specifications are stamped on the end per ASTM or AASHTO. Certification documents are provided for all orders. Headed pins are also available. Dimensions vary by state. Contact Portland Bolt for detailed information.

Manufacturing
Portland Bolt manufactures barrier pins for both state and federal highway projects. State Department of Transportation approved pins include: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, Oregon, Utah, and Washington. Other state pins are available.
Barrier pins are hot forged, significantly reducing costs compared to a welded pin. All operations, including the galvanizing process, are performed in-house. Certification is provided with barrier pins and specification stamping is done in compliance with ASTM and AASHTO.
