This program of cladding the underneath of 91 canopies over 6 stations was technically demanding due to a number of factors. Wind loading from passing trains was one factor. The need to keep these large panels flat, due to the highly reflective nature of the #4 stainless steel finish was another. The canopies are a gull wing design. The panels at the canopy perimeter have a 3” return leg upwards, partially enclosing the support steel which partially enclose the steel sub frame on 5 sides. For this reason the dimensional tolerances of all of the panels over this complex shape was critical. The sheet metal work on all panels had to be very exact. Corrosion resistance was another issue. For this reason, the panels have a 0.0375” #304 stainless steel backer and are sealed with high modular silicone all around, effectively sealing the panel. All exterior surfaces are stainless steel, ensuring a long service life in a reasonably harsh environment. The panels form the underneath of the canopies and are installed from underneath. It was desirable to have the panels as light as possible, in order to aid in the installation and reduce the chance of panel damage during installation. Given the above design constraints, the chosen panel construction is a laminated panel, using a thermosetting epoxy adhesive and an aluminum honeycomb core, with the face skin and backer sheet laminated together in a high-strength sandwich. Laminated honeycomb structures offer some of the highest stiffness to weight ration of any materials. Properly engineered and manufactured, they produce exactly the desired performance results. They can also provide a striking visual effect as well. The photographs illustrate the effectiveness of the panels to stay flat, as seen by the reflected images.
