Pultruded FRP Cooling Tower Filling Frame Grating are use FRP pultruded “I beam”, “T shape” and other profiles as the load bar and use pipe and rod as connection bar then through certain assembly process to make different specifications of the gap plate,which known as pultruded fiberglass filler shelf and Grating. Such filling rack and grating include standard and custom-made non-standard type which can change the load bar’ shape ,size or spacing, closed or anti-skid sand and etc according to customer requirements or specific usage conditions .

FRP cold-water tower filling rack technical description:
Fiberglass filling bracket use special resin, glass fiber yarn and reinforced surface veil by special pultrusion equipment pultruded to a variety of I-shaped, fibergalss tubes , fiberglass rod , and then assembled according to users’ requirements with a variety of cooling Tower filling rack. Such rack mainly used in large mechanical ventilation cooling towers and hyperbolic natural ventilation cooling towers and it’s alternative products of cement grid and cast iron castor filler bracket.
