Railway square ruler for measuring right-angle misalignment of track panels, track maintenance measuring tool

The railway square is primarily used as a specialized measuring tool for inspecting right-angle misalignments in railway track panels.

1. Aluminum alloy ruler body: Utilizes a square tube structure with high mechanical strength, stable flatness, permanent deformation resistance, and stable product performance.

2. Insulating plate: Made from epoxy glass fiber board material (commonly known as FR4), it exhibits high mechanical strength at temperatures ranging from -40°C to 120°C, maintains stable mechanical dimensions without deformation, and ensures stable electrical insulation performance in high-humidity environments.

3. Measuring head: Constructed from imported stainless steel material with high hardness (Rockwell 52), it is rust-proof and offers stable and reliable mechanical dimensions.
