 Guardian has been manufacturing FRP since 1983 with a particular focus on FRP Composite Bridges since 1996.

Multi Use Bridges are often in remote locations.

Guardian designs, fabricates, delivers and assists with on site installation so that the owner understands the procedures to deliver on time and budget.

FRP is lightweight and strong, modular in width and length allowing the owner to get 100+ years in service.


Guardian has P.Eng stamps for all of Canada which is provided upon the sales order or contract.

Typically, our bridges require no ongoing maintenance because fiberglass is robust and durable. In fact,  Fiberglass bridges do not rust, rot, and are not subject to insect damage, and can even be buried directly into the soil. Fiberglass materials are not affected by high humidity or salt water environments.



FRP Bridges can be shipped assembled or dis-assembled in manageable skids to the site and then carried in by ATV, or by hand.



With our CNC machines, FRP prefabricated bridges are pre-drilled and all connection hardware needed for assembly. Often these brigdes are installed by volunteers, park maintenance crews, or contractors, using standard hand tools. In most cases no special experience or heavy equipment is required as Guardian provides assembly drawings and instructions with the sales order, and even training on site to assist the owners for a day or two when requested.


Trail Bridges are structures that are functional often requiring 10 ton groomer, emergency services loading.


See examples below
