3 1 ⁄ 2 " (89mm) no holes. Materials: Aluminum, Hot Dip, Mill-galvanized (pre-galvanized) to ASTM A-924, Hot Dip Galvanized after Fabrication (HDGAF) to ASTM A-123. Sufficient connectors are supplied to assemble straight sections and fittings for each order. Connectors for field cuts are to be ordered separately. Free passage of air through the openings results in a 68% open area. Corrugations give great lateral rigidity to the bottom transmitting the load to the side rails. Solid Trof have the same corrugations but have
