MakeABridge®: A Vision Forged in Aluminum
Montreal, QC – April 2018 — In a groundbreaking demonstration of strength and engineering precision, MAADI Group‘s aluminum pedestrian bridge system, MakeABridge®, has proven its performance under rigorous testing and has since evolved into a lighter, stronger, and more versatile product. With continued innovation and strategic material upgrades, the company is shaping the future of modular bridge solutions for both civilian and military use.
Spotlight in Light Metal Age Magazine
This advancement was prominently featured in the April 2018 issue of Light Metal Age, a leading industry publication that highlighted the engineering and material innovations behind the MakeABridge system. The article detailed a critical structural test conducted at the University of Waterloo (UW), where a 20 ft-long, 6063-T54 aluminum alloy bridge specimen demonstrated exceptional strength and ductility. Narrowed to just 2 ft in width to fit the testing frame, the specimen reached a peak total load of 183 kN (41.0 kip) — equivalent to a distributed load of 1,025 PSF — while maintaining structural integrity even beyond its maximum loading point.
Stronger Materials, Better Performance
Following this pivotal test, Light Metal Age reported on MAADI Group’s transition to 6005A-T6 aluminum alloy for future bridge models. This alloy provides an ultimate strength of 260 MPa (37.7 ksi) and a yield strength of 240 MPa (34.8 ksi)—a 15% improvement over the original material. These enhancements allow MakeABridge to meet the increasing demand for lightweight, high-strength, and maintenance-free infrastructure.
Innovative Weld-Free Engineering
One of the most notable features of the MakeABridge design is its weld-free structure. Using precision-extruded aluminum components, the system avoids heat-induced damage and maintains full mechanical integrity. Instead of welding, it uses a combination of patented interlocking elements, shear connectors, and the innovative moment-resisting joint known as the tripod node.
Real-World Applications and Client Adoption
Since the original UW testing, MakeABridge has been successfully deployed in real-world projects. A floating spa in the Port of Montreal was the first commercial client, purchasing seven bridge units after seeing the prototype at a tech showcase. The spa required lightweight, corrosion-resistant walkways with visual appeal—exactly what MakeABridge delivered.
Military-Ready Bridges for Rapid Deployment
As detailed in Light Metal Age, MAADI Group is now adapting its technology for military applications (View the Factory Acceptance Test (FAT) in the video below). A new prototype system is being tested for gap-crossing operations and emergency deployment. Designed to fit inside a 20 ft container, the bridge is helicopter-transportable and arrives with many pre-assembled parts. It offers a modern alternative to traditional Bailey bridges, with faster deployment, higher durability, and reduced logistical complexity.
The Future of Modular Aluminum Infrastructure
MAADI Group’s continued R&D efforts, in collaboration with the University of Waterloo and ÉTS, reflect a commitment to engineering excellence and material innovation. As featured in Light Metal Age, this dedication positions the company at the forefront of modular bridge technology.
The company’s vision remains clear: to unlock the full potential of aluminum extrusion in structural applications, transforming the way bridges are designed, built, and deployed.
