Bedford Reinforced Plastics (Bedford, Pennsylvania, USA), a full-service supplier offering a full line of glass fiber reinforced plastics (FRP), announced on April 29th the launch of ReadySpan, a pre-fabricated, easy-to-install, high-speed ship , modular pedestrian bridge system and one of five offerings among the company’s ReadySeries solutions.
ReadySpan trail, park and golf bridges are made from Bedford’s high-quality FRP and are said to be virtually maintenance-free for decades. Additionally – unlike bridges made of wood and metal – Bedford says the long-lasting bridges won’t shrink, swell, warp, corrode, attract insects, or fail in extreme weather conditions.
“We look forward to the introduction of ReadySpan. It offers incredible value to our customers in need of span spanning solutions, ”said Ted Harris, sales account manager for the ReadySpan bridge product line. “ReadySpan bridges are designed for safety and will last in harsh environments for over 75 years. They do not require regular or scheduled maintenance. It’s an unprecedented solution. “
The GRP truss bridges can span up to 100 meters without intermediate supports. Bedford notes that all prefabricated bridges have been subjected to static analysis. In addition, Bedford provides custom design and analysis for each bridge to ensure that it meets the load-bearing requirements specific to the location and intended use. This analysis includes a PE-stamped template package with CAD drawings and static calculations.
ReadySpan includes both Bedford’s P-Series for pedestrians and the PV-Series bridges for bicycles, horses and light vehicles. Light vehicles include ATVs, golf carts, and other vehicles weighing up to 10,000 pounds, also known as an H5 loader.
The bridge systems are made from high strength E-glass and isophthalic polyester resin for strength and durability. The railings are at least 54 “above the floor deck, and the trusses have three-inch continuous horizontal safety rails on the inside. Standard options include olive green and brown, and since Bedford incorporates the color during manufacture, no painting is required.
According to Bedford, the GRP bridges are lightweight so they can be easily transported to remote locations. Installation is easy. The components are manufactured on CNC machines and supplied pre-drilled with all necessary hardware components; Only hand tools are required for assembly, eliminating the need for heavy equipment, welding, or excessive construction site work, the company adds. The pedestrian bridges can also be supplied in modules that require limited assembly, or fully pre-assembled to fall into place.
In addition, ReadySpan is designed to expand the capabilities of Bedford’s custom footbridge functions. Bedford’s custom bridges are currently used in national, state, county, and city parks in the United States, as well as residential, commercial, and municipal applications. Each prefabricated bridge is made in Bedford’s Pennsylvania factory.
