What are the dimensions of a 6-hole 54E1 steel rail joint bar?

Feb 06, 2026 Leave a message

A rail fish plate is a steel connector installed at rail joints to restore stiffness continuity and enable bending and shear forces to pass across rail connections safely. GNEE RAIL manufactures fish plates suitable for GB rails, UIC50/54/60, JIS rail standards, AS1085 profiles, BS11 sections, AREMA/ASCE rail systems, and heavy crane rails defined by DIN536 and QU standards, with joint system coordination.

What are the dimensions of a 6-hole 54E1 steel rail joint bar?

 

A 6-hole 54E1 (or UIC54) steel rail joint bar, commonly known as a fishplate, is a structural steel component used to securely connect two 54E1 rail ends together. It features six bolt holes, providing high strength and stability for medium-to-heavy load traffic in railway, crane, or industrial track applications.

 

The first gap of rail end is 4mm, length 920mm, weight 22.74 kg/pc, the drawing as below:

Second gap of rail end is 0 mm, length 940mm, weight 22.90 kg/pc, the drawing as below:

The joint bar with 6 holes refers to the number of bolt holes present on the joint bar. These bolt holes are used to fasten and secure the joint bar to the rails using bolts or other fasteners.

What is the material of the rail joint bar?

 

Rail joint bars (fish plates) are primarily manufactured from high-strength steel, specifically carbon steel or alloy steel, designed to withstand heavy loads and resist deformation. Common materials include hot-rolled steel (e.g., 55# steel, Q235, Q255), while insulated joints use specialized thermosetting composites or fiberglass for non-conductive properties.
