All plate products shall comply with astm a572 grade 50. 3. All steel tubing shall be triple coated for rust protection using the in-line electroplating Coat process. Tubing shall be internally coated with zinc and organic coatings to prevent corrosion As manufactured by allied tube & conduit. 4. Structural steel shall be detailed, fabricated and erected in accordance with a.i.s.c. Specifications. 5. All shop welds shall be executed in accordance with the latest edition of the American Welding Society (aws) d1.1 specifications. All welds shall be continuous where length is not given, and be made using e70xx .045 wire. 6. Shop connections shall be welded unless noted otherwise. Field connections shall be as Indicated on the drawings (if required). All fillet welds shall be a minimum of 3/16" unless Otherwise noted. Field welds shall not be allowed. 7. All high-strength bolts shall comply with ASTM a325 type 1. All nuts shall comply with ASTM A563dh, and washers shall comply with ASTM f436. 8. All high strength bolts shall be tightened to a snug tight condition. 9. All structural steel shall be painted with one shop coat (2.5 to 3.5 mils thick min). This coat is a weather resistant powder coating based on Polyester TGIC (Triglycidyl Isocyanurate). To -- 1 of 3 -- achieve optimum adhesion, it is recommended that the proper treatment and drying ake place before coating. Polyester powder (TGIC) specifications shall be as follows: - pencil hardness (astm d-3363) - humidity (astm d-2247) - solvent resistance (pci method)- 50 dbl rubs sl. Softnes C. One (1) Desert San color Fabric designed to cover the 40’ x 40’ shade. FABRIC SPECIFICATION: 1. Fabric shall be a high-density polyethylene with ultraviolet additives, with monofilament and tape construction giving a stable material and rachel knitted to ensure material will not unravel if cut. 2.
