Product Introduction
As a typical representative of clip-on fastening, KPO fastening system has KPO3, KPO6, KPO9 and other product categories. The components include KPO Clamp, screws of specific specifications, pins, bolt and nut assemblies for connection and rail pads. KPO Clamp mostly uses Q235 material, and the other metal parts use different grades of steel according to the function and strength requirements. The main purpose of this system is to firmly fix the rails on the sleepers to ensure the stability of the track structure. Its advantage is that it has good fastening performance and can adapt to complex railway operating environments. The production process involves a series of processes such as metal smelting, forming processing (such as forging, stamping), mechanical cutting processing and surface treatment (such as blackening, galvanizing).
KPO Clamp Rail Fasteners SystemKPO clamp rail fastener system is a fastener system for railway tracks, mainly used to fix the rails on the sleepers to ensure the stability and safety of the tracks.

High-quality materials: The main components such as the clamp plates and bolts are made of high-strength materials, which can withstand the huge loads generated by the train running and various complex mechanical effects, such as tension, compression, shearing, etc., to ensure that deformation, fracture and other damage will not easily occur during long-term use, thereby providing reliable fastening for the track and ensuring the safety and stability of train driving.
Stable structure: Through reasonable structural design, the clamp plates can be tightly clamped on the rails, and then with the help of the fastening force of the bolts, the rails and sleepers are firmly connected together, effectively preventing the rails from moving longitudinally and transversely under the train load, maintaining the accuracy of the track gauge, reducing the deformation and displacement of the track, and improving the overall stability of the track structure.

Product Packaging & Delivery
Waterproof Oxford cloth wrapping + metal buckle fixed packaging: For large bundles of fasteners, first use waterproof Oxford cloth to wrap the whole thing, and tighten the edges of the Oxford cloth with metal buckles and nylon ropes to ensure tight wrapping. Wrap several turns of high-strength nylon belt around the outer layer of the Oxford cloth to enhance the overall firmness. Place the wrapped goods on a wooden pallet and fix the goods to the pallet with steel belts.
