About this file
This document is a technical specification and design drawing set for a standard awning structure with precast reinforced concrete counterweights. The awning features a curved joist frame fabricated from high-resistance galvanized GHT tubing and plates conforming to Grade 72 structural steel (72,000 PSI yield, 75,000 PSI ultimate stress) per ASTM A653 and AUS 1397 standards, with Z180 zinc coating (180g/m²). The structure measures 20.00 meters in length with an 8.00-8.60 meter height and incorporates upper and lower galvanized tube chords, galvanized tube web members, and bolted connections using galvanized plates. All welded points must be polished and finished with two coats of anticorrosion paint and two coats of aluminum paint using E70XX welding rod. The frame includes lateral wind bracing, X-bracing galvanized tube stringers, and a multiple Franklin spike lightning rod system with delta-type ground connections on the first and last frames. Connections must be designed for assembly/disassembly using A325 bolts or G60 threaded rods per structural design requirements.
The awning covering consists of white, blackout polyester fiber canvas with PVC coating at 24 oz/yd² (680g/m²), featuring UV protection, fungus retardant properties, and flame retardant treatment (Fortoflex or similar). Canvas is secured using black polypropylene rope at least 1/4 inch thick with UV resistance. The structure includes precast concrete counterweights with compressive strength of 3,000 PSI and reinforcement steel at 40,000 PSI yield, designed to support 1.5-2 tons per base. Counterweights are semi-buried with 0.10 meters minimum above ground level and filled with mudcrete, featuring galvanized steel plates with embedded bolts for structural attachment. The design accommodates a sea container obstacle and includes 400W LED reflectors and bubble levels for field installation and leveling.
