History of Bridge-Plate & Multi-Plate
• 1931 – 6” x 1.5” (152 x 38) corrugated plate
• Trademark name Multi-Plate
• 1952 – improved to 6” x 2” (152 x 51) corrugation
• 1960’s – development of larger spans “Super-Spans”
• 1967 – 12.2m span x 6.4m rise Armstrong Bridge• 1975 – 15.5m span x 8.4m rise Vieux Comptoir• 1984 – 18.0m span x 7.4m rise Cheese Factory Bridge
• 1999 –added 400 x 150 (15 ¾” x 6”) deep corrugation profile
• Trademark name Bridge-Plate

History of Bridge-Plate
• 2000’s to present
• Bridge-Plate (Deep Corrugated Structural Plate (DCSP) pushes arch span envelope to 21m
• Enhanced manufacturing methods - Roll curving plates
• Introduced a new family of buried plate structures
• “Metal Box Culverts” - spans to 15m
A Canadian Company Since 1908
“The Canada Ingot Iron Company Ltd”
Benefits of Buried Plate Structures2/

Benefits of Buried Plate Structures
• Segmental plate structures economically shipped to remote or international locations via containers
• Ease of installation w/o large cranes
• Customized shapes to fit the application
• Cost efficient - provides lowest possible life cycle cost
• Wide range of loading conditions
• Deep bury• Heavy Live Loads (haul trucks, track vehicles)• Typically have reserve capacity for overload conditions• Seismic forces
