E-glass direct roving is made directly from a 2000 tip bushing or a 4000 tip bushing. Direct Rovings are primarily used in filament winding and pultrusion processes. Typical products are pultruded rod, pipe, tanks, woven roving and chemical resistant grating.

Product Characteristics:
Direct Roving is made in one manufacturing step with a special reinforcement sizing. The glass fibers are bonded into a single strand. The tension of each glass fiber in the strand is uniform. There is low fuzz, quick wet out and excellent mechanical properties.
