In a 2nd strategy, typically called “Push Through Letters”, the letters cut from the aluminum face. Acrylic letters are cutout a little smaller sized to fit thru the cut out aluminum. The density of the acrylic letters will vary from 1/2″ thick to 1″ thick. The acrylic letters are then fused to a backup acrylic sheet, and the backup sheet is then connected to the back of the aluminum face so that the letters press thru the cutout spaces. Bronze/ Brass. Bronze and brass are mostly alloys of copper and zinc, plus traces of other metals, in differing proportions. They can be cast from ingots, sawn from sheet material or extruded. Smaller sized sign fabricators are usually limited in the size of areas that can be poured. Their bright finishes can be preoxidized by chemical attack or can be delegated oxidize naturally in the weather. If oxidization is not preferable, manganese can be contributed to the alloy and the finish can be maintained through such coatings as lacquers or liquid plastics. Red brass is an alloy of 84-86 percent copper and 14 percent zinc. Yellow brass is an alloy of 70 percent copper and 30 percent zinc. Brass accepts chrome plating much better than bronze, and is therefore preferred for that purpose. Casting. Cast metal signs are strong, one piece signs or individual letter forms of a fairly heavy gauge. They are soften used when sturdiness or prestige recognition is required. Installing. Metal signs are mounted with metal-rod wall fasteners, numerous adhesives, or by welding, brazing, or soldering onto a metal surface. Sawing, Cutting Fabrication Process. A paper pattern is made and connected to a metal plate. Following the pattern, the sign is eliminated with a band saw. Any metal is usable that can be sawed. Stainless-steel, as an example, can be utilized up to a density of about 1/8 inch (.3 millimeters) or aluminum approximately 1/2 inch (1.3 millimeters). Finishing needs only the removal of any rough edges by belt sanding and filing. Additional treatment could include enameling, plating, or anodizing. Wall attachment methods are basically the exact same as those for cast metal signs. Making Sheet Metal. Fabricated sheet metal signs are hollow, thin-walled three-dimensional signs. They are built by hand from many different pieces. Sides and face of the sign’s are flat and usually broad in location. Various sheet metals such as stainless-steel, copper, or aluminum could be used. Fabrication Process. A paper pattern of the signface is connected to the metal and the kinds are eliminated. These forms are offered depth with the addition of sides. Sides and face are seamed by either soldering for steel, heliarc welding for aluminum, or brazing for copper. Size limitations for this sort of sign are very versatile and can rise to 10 feet (3 meters) in overall length. The surface of the sign can be completed by polishing, plating, anodizing, or enameling.
