FRP Pultruded Grating
Magic pultruded grating is the result of a continuous molding technique in which glass roving, glass matting and a synthetic surface veil are literally pulled (pultruded) simultaneously through a flame-retardant polyester or vinylester resin bath. It also features a two-part mechanical locking cross-rod, which increases the support and stability of the grating under extreme loads. The patented flush-top design of the cross-rods and bearing bars also enhance the unidirectional strength and provide easy fabrication and installation.
