AGY produces conventional or multi-end roving products from S-2 Glass fibers. These roving products are typically used for composite reinforcement applications where high performance fiber reinforcement is required. S-2 Glass Rovings are produced in a variety of constructions, varying by total linear density and by the type of size system applied to the fibers. The products are broken down by the size system and its resin compatibilities. There are 4 families of S-2 Glass Roving products - 365 rovings, 449 rovings, 463 rovings, and 933 rovings. These roving products are described with the size chemistry number followed by the nominal yield in yards per pound.

| Woven roving glass fabrics of KROSGLASS S.A. are produced on weaving looms from rovings ER 3003 and ER 3003 B. These rovings are made of glass fibers of alkali-free boron-aluminium-silica glass of type E (contents of alkali metal oxides less than 1%). The fabrics are made of direct roving having filament diameter 11 ÷ 22 µm (depending on linear mass of the roving used). Rovings with chemical active vinyl-silane or metacrylosilane coating are used in fabric production, thus enabling a direct application of fabrics in production of laminates (no additional operations of surface finishing off are required), and good polymer-to-glass adhesion is ensured. |

ZenTron high strength roving is a single-end S-2 Glass roving product that consists of numerous L or T Filament continuous glass strands gathered without mechanical twist into a single bundle and treated with one of two epoxy-compatible size systems.
ZenTron is suitable for a number of composite and non-composite processes and applications, including weaving, filament winding, pultrusion, and texturizing. The 758 size system was developed for composite and reinforcement applications, while the 721B size system was developed for texturizing and thermal applications.
ZenTron products are described with the size chemistry designator as well as the nominal yield in yards per pound.
There are two families of ZenTron products - L Filament and T Filament. |

Direct Rovings deliver excellent processing and mechanical properties for the composite part.
The strands offer compatibility with most resin systems including polyester, vinyl ester, epoxy, phenolic, polypropylene and polyamide.
Typical end-use processes for Direct Rovings include:
filament winding to manufacture hollow tubular structures such as pipes, storage tanks, pressure vessels
pultrusion for composite profiles used in consumer goods, sports and leisure, telecommunications and infrastructure parts
knitting and weaving where the semi-finished product (fabric) can be used in a wide range of applications (wind energy, marine, transportation sports and leisure and infrastructure)
Using LFT (Long Fibre Thermoplastic) Direct Roving reinforcement in thermoplastic processes enables moulders to produce structural or semi-structural parts for the automotive industry compounding the fibreglass in-line with injection or compression moulding techniques.
