Exceed safety requirements with Port Washington, NY fiberglass handrail
Fibergrate has made safety one of their highest priorities by offering a non-conductive, anti-slip flooring and stair package with available handrail system. Dynarail and a fabricated handrail and ladder system meet or exceed OSHA, IBC and other building code requirements for safety and design. Fibergrate’s systems are also easy to assemble in the shop or field. This line includes a railing, kickplate, ladder and rungs, as well as standard walk-thrus and safety cages all manufactured in a corrosion resistant, low maintenance, pultrusion process. In addition to the low maintenance, the Dynarail system is also fire retardant and nonconductive. The system has a flame spread rating of 25 or less and is tested in accordance with ASTM E-84 while meeting the self-extinguishing requirements. Fiberglass is electrically non-conductive for safety and has low thermal conductivity.
The corrosion resistant materials in the fiberglass grating reduces the daily and yearly maintenance, and replacement costs. Once you install fiberglass you will find it offers outstanding durability and extended life span compared to metal.
