| HIGH-STRENGTH FIBERGLASS SHEETS |
|
| High-strength fiberglass sheets are used for many industrial, commercial and marine applications. Advantages of these materials, in addition to high strength and stiffness, include resistance to corrosion even in harsh environments, long-term durability in wet and marine applications, remarkable toughness, stiffness, and impact strength when used as a liner panel or cover plate, and relative ease of installation. High-strength fiberglass sheets are manufactured in three "types". The difference between the "types" lies in the kind of fiberglass reinforcement incorporated into the sheet, and the resulting fiberglass content and physical properties, as indicated in Table 1 below.

| Table 1 - Characterization of reinforcements and physical properties for high-strength fiberglass sheets. High-Strength fiberglass sheets are used in many applications, including industrial access covers, equipment mounting plates, corrosion-resistant and impact-resistant liner panels, stiffeners and batten strips, baffles in water treatment facilities, and many marine and shipboard uses. Sheet sizes and thicknesses available for each "type", and a review of common applications are summarized in Table 2 below.

| Table 2 - Summary of sheet sizes, thicknesses and applications. Options include improved resistance to extremely alkaline conditions by incorporation of a synthetic surfacing veil, and reduced flammability by use of a fire-retardant resin system. Sheets can be supplied that meet performance criteria of all grades of the MIL-P-17549 specification for marine structural sheets. Sheets can be supplied that exibit burning characteristics meeting criteria of the MIL-R-21607 specification. Requests for quotation and availablity faxed to 631-422-2811 will receive a prompt response.
