StrandLock post-tensioned level crossing system

Crossing Systems

StrandLock System

Post-tensioned panels locked into a single unified structure with steel strand reinforcement. No movement, no gaps — engineered for the most demanding road crossings.

Post-Tensioned Heavy Traffic High Angles Permanent

One Structure, Zero Movement

Steel strands run through integrated channels in each panel and are hydraulically tensioned on site, locking the entire crossing into a single rigid structure. The result: absolute dimensional stability under heavy traffic, high crossing angles, and thermal cycling. Designed for permanent installations where long-term performance is non-negotiable.

Why Specify StrandLock

Technology

Post-Tensioned Locking

Steel strands run through integrated channels and are hydraulically tensioned, compressing all panels into a single unified structure. Unlike bolted or interlocking systems, the entire crossing behaves as one piece — eliminating panel separation, vertical movement, and gap formation under traffic.

Geometry

High-Angle Crossings

Accommodates complex crossing geometry and high road-to-rail angles that conventional systems can't handle. Enhanced vibration resistance and thermal expansion tolerance means the crossing stays locked and flat regardless of temperature swings or dynamic loading.

Permanence

Decades of Stability

Designed for permanent, heavy-traffic installations where the crossing must perform flawlessly for decades. Once tensioned, the system maintains its dimensional integrity with minimal maintenance — the locked structure resists the gradual loosening that plagues other systems over time.
