Kingrail Parts is one of the most professional railroad tie plate manufacturers in China. We can manufacture rail tie plates suitable for various rail types, i.e. UIC 60, UIC 54, RN 45, 90 A. We can produce railway tie plates by casting, forging or rolling.
Railroad Tie Plate Definition:
Railroad tie plate, also known as rail base plate or railway soleplate, is a steel plate used between flange T-shaped rails and sleepers on railway tracks.
Rail tie plates increase the load-bearing area and keep the rails in the correct rail gauge, and fasten them to the wooden sleepers by passing spikes or rail bolts through the holes in the tie plates.
Types of Railroad Tie Plate:
1. Rolling tie plates
With a wealth of professional steel rolling experience, Kingrail Parts can produce 11-inch, 14-inch and 14-3/4-inch rai tie plate molds for 5-1/2 and 6-inch rail bases.
2. Forging rail tie plates
Kingrail Parts has 300T~1600T forging friction presses and 7 5T electro-hydraulic hammer die forging production lines. The annual forging capacity is at least 12,000 tons, and the forging capacity is 400,000 pieces.
3. Casting rail tie plates
Kingrail Parts has two casting workshops for manufacturing cast rail tie plates. We are able to develop molds in a modern way to ensure that precise dimensions are obtained from hot pre-sand or machining methods.
Our company exports rail tie plates that meet the standards of AREMA, UIC, BS, etc., and can provide single-shoulder tie plates or double-shoulder tie plates according to customer needs.
4. One-shoulder rail tie plates
For a single-shoulder tie plate, the shoulder is always designed at the end of the tie plate. The short end of the board or the rail gauge end is placed inside the rail, which is why customers always require the width of the rail bottom. One-shoulder tie plates are usually used for rails weighing from 56 to 100 pounds.
5. Double shoulder rail tie plates
Double-shoulder rail tie plates are usually used for rails larger than 100 pounds. They are available in 2-hole, 4-hole, 5-hole, 6-hole and 8-hole types.
