Steel Rail and Railroad Fasteners

As a leading steel rail track suppliers, Kunshan Signum supplies various types of OEM&ODM fasteners and standard track products. We can design and supply rail system accessories, such as rail clips, rail clamps, track bolts, screw spikes, rubber pads, steel base plates, nylon PA66 dowels, fish plates, etc.

Steel sleepers (also known as rail ties or railroad ties) are foundational railway components that support rails and maintain track gauge. Steel sleepers are used on heavy-haul freight tracks, industrial railways, and in mining.

 In Tunnel Boring Machine (TBM) projects, steel sleepers are primarily used as temporary track systems to facilitate logistics—transporting segments, equipment, and muck—while adapting to the tunnel's curved invert. They are specifically engineered to withstand the high vibrations and heavy loads of TBM construction vehicles. 

Signum Rail Fastening offers a wide range of sleepers for different purposes. We customize the matching steel sleepers and track fixing system according to the size of the tunnel and the type of track used. The excellent technical team and processing experience ensure that the sleepers produced by Signum team are of stable quality and have a good user experience.

SKL Fastening System:

The SKL (Schienen-Klemmen) Fastening System, also known as the Vossloh or W-type system, is a resilient, screwed-direct rail fastening solution primarily used on concrete sleepers and ballastless track

Pandrol Fastening System:

The Pandrol Fastening System is a global leader in resilient rail fasteners, known for its iconic threadless, self-tensioning designs that provide "fit-and-forget" reliability across all track types.

Nabla Fastening System:

The Nabla Fastening System is a high-performance, resilient rail fastening solution widely recognized for its exceptional lateral force absorption and electrical insulation.

KPO Fastening System:

The KPO Fastening System (often called the K-type system) is a heavy-duty, bolted clamp fastening solution.It is known for its rigid connection and high clamping force, making it the industry standard for crane rails, mining tracks, and heavy haul railways.

Dog Spike Fastening System:

The Dog Spike Fastening System (also called the Cut Spike System) is the most traditional and widespread rail fastening method used in North America, specifically designed for timber (wooden) sleepers.
