Bases and tops shall be injection molded, glass reinforced, thermoplastic polyester for maximum corrosion resistance. Tops shall be provided in a quad head configuration for use at the corners and edges of the grating panels. Pedestal tops are to be manufactured such that there is free drainage of fluids. Color shall be light gray. Pedestals shall be 2-1/8" x 3/16” square tube as manufactured by the pultrusion process and in accordance with Section 2.3 - STRUCTURAL SHAPES. Adjustability shall be achieved with a fiberglass all-thread rod and 316 Stainless Steel nut inserted into the non-metallic molded fittings. Color shall be light gray. Substitutions: Other products of equal strength, stiffness, corrosion resistance and overall quality are acceptable only with prior approval by the engineer, after review of the proper supporting data. PART 3 EXECUTION 3.1 INSPECTION Shop inspection is authorized as required by the Owner and shall be at Owner's expense. The fabricator shall give ample notice to Contractor prior to the beginning of any fabrication work so that inspection may be provided. The grating shall be as free, as commercially possible, from visual defects such as foreign inclusions, delamination, blisters, resin burns, air bubbles and pits. The surface shall have a smooth finish (except for grit top surfaces). 3.2 INSTALLATION Contractor shall install gratings, grating pedestals, and embedment/ledge angles in accordance with manufacturer’s assembly drawings. Fasten materials securely in place with fasteners as specified herein. Field cut and drill fiberglass reinforced plastic products with carbide or diamond tipped bits and blades. Seal cut or drilled surfaces in accordance with manufacturer's instructions. Follow manufacturer's instructions when cutting or drilling fiberglass products or using resin products.
