Civil Infrastructure
Description
PontisGuard Metal-Span is a high-load capacity, mechanical expansion joint system specifically engineered for bridge decks and highway viaducts. Featuring heavy-gauge galvanized steel or aluminum alloy edge rails and a central elastomeric compression seal, this system provides a robust solution for managing large-scale structural movements in high-traffic environments.
The system is anchored directly into the structural concrete using high-tensile steel studs, ensuring a permanent mechanical bond. It is designed to facilitate smooth vehicle passage while simultaneously protecting the underlying bridge piers and abutments from water, salt, and debris ingress.
Engineering Specs
Key Features
- High-Tensile Mechanical Anchoring — uses multi-point steel studs to ensure the system remains secure under constant heavy vehicle loading.
- Superior Impact Resistance — engineered to withstand the dynamic forces and vibrations generated by high-speed truck traffic.
- Integrated Moisture Management — features a continuous elastomeric seal that prevents bridge deck runoff from corroding structural piers.
- Corrosion-Resistant Finish — all metal components are hot-dip galvanized or treated with industrial-grade coatings for longevity.
- Large Movement Accommodation — specifically designed to bridge wide gaps and handle significant thermal expansion and contraction.
- Low Maintenance Profile — the central seal is designed for easy inspection and can be replaced without removing the metal hardware.
