Magic pultruded grating is the result of a continuous molding technique inwhich glass roving, glass matting and a synthetic surface veil are literallypulled (pultruded) simultaneously through a flame-retardant polyester orvinylester resin bath. It also features a two-part mechanical lockingcross-rod, which increases the support and stability of the grating underextreme loads. The patented flush-top design of the cross-rods and bearing barsalso enhance the unidirectional strength and provide easy fabrication andinstallation.
