China Railway Guide Plates, Rail Guage Baffle Plates Manufacturer
Guide Plates, also called rail gauge apron, rail baffle plate, mainly used in railway clamping fastening systems, which belong to rigid-type fasteners.
Gauge Apron Plate is one of the important components of the railway, Its function is to adjust the gauge and transmit the horizontal thrust of the rail.
The rail gauge apron is divided into joint gauge apron, intermediate gauge apron, height-adjusting gauge baffle and heavy-duty gauge apron.
Anyang Railway Equipment Co., Ltd. provides gauge apron plate in Plain, Oxide Black, Sherardizing, Nitriding, Dacromet, Galvanized and Sherardizing Nnickel for customers to choose.
Railway Guide Plates(Gauge baffle plates) are often used for Type-I and Type-II railway fastening systems to fix the connection between rails and sleepers. The raw materail for raiwlway guide plates is a kind of special-shaped section steel, which is produced by hot rolling method.

The implementation standard of gauge baffle steel is YB/T2010-2003.
The 6# and 10# guide plates follow TB/T3065-2020;
The 14# and 20# guide plates follow TB/T1495-2020. In addition, the standards are also implemented at the same time: Q/CR563, Q/CR564
The grade, chemical composition, tensile and cold bending properties of baffle steel shall comply with the requirements of Q235A and Q235B grade steel in GB/T 700 standard.
| Material | Chemical composition/%, not more than |
Tensile test, not less than | Cold bending test 180°, B=2a | ||||||
| C | Mn | Si | S | P | ReH/ MPa | Rm/ MPa | A/% | Bending diameter d | |
| Q235A | 0.22 | 1.40 | 0.35 | 0.045 | 0.045 | 235 | 370～500 | 26 | a (longitudinal) |
| Q235B | 0.20 | 1.40 | 0.35 | 0.045 | 0.045 | 235 | 370～500 | 26 | a (longitudinal) |
| Note: 1. In the cold bending test, B is the width of the sample, and a is the thickness of the steel. 2. YB/T 2010 stipulates that the sulfur content of Q235A steel is not more than 0.045% (GB/T 700 stipulates that the sulfur content of Q235A steel is not more than 0.050%). |
