Letters are 1/4″ aluminum, water-jet cut and anodized clear. They’re attached to a laser-cut & powder-coated steel panel. This panel is backed by a wood panel of 2×6’s. There’s 3 lengths of all-thread running horizontally through the boards to hold them together. No joinery & glue-up like the many sandblasted panels of years past. Posts are p.t. 6×6’s, wrapped and capped in cedar. Paint is trim color from the building.
