The Société de développement de la Baie-James (SDBJ) needed to replace an older crossing over the Kakaskutatakuch River at km 139 on Route Billy-Diamond in Northern Quebec. The project team opted for a set of twin Bolt-A-Plate Rounds for the replacement, with Best-Kote Buried Bridge Coating on the lower sections only, and step-bevelled ends that contoured to the embankments.
For a strong, effective bridging alternative, Bolt-A-Plate is the product of choice for its light weight, strength and versatility. Available in a wide variety of shapes and sizes, it is perfect for highly economical buried metal bridge and drainage structure construction or replacement, as well as many other applications.
Best-Kote extends service life in aggressive environments
Premium coatings like Best-Kote extend the service life of structures in aggressive environments. Building on the years of proven performance of polymer-coated corrugated steel pipe, AIL has partnered with some of the world’s leading developers of coatings to provide Best-Kote for superior protection and long-term durability.
- +75 YEAR service life
- Economical solution for extended service life of structure; ideal for aggressive environmental conditions
- Can be applied to all or part of a structure
- Special bolts and fasteners maintain integrity of coating during assembly
The coating system provides two layers of protection — a zinc-rich base layer and a Polymer-finish layer over top. The result is 360° protection against corrosion, abrasion and inorganic acid, salts or alkali (diluted).
