Architectural Castings

Architectural castings are lightweight, easy to install, and are available in a wide variety of materials and finishes including GFRG, (Glass Fiber Reinforced Gypsum), GFRC, (Glass Fiber Reinforced Concrete), IMS, (Interior Molded Stone), and GFRP, (Glass Fiber Reinforced Polyester Resin). Architectural castings are available for both interior and exterior applications, and are ideal for renovation and restoration projects. Using today's modern mold fabrication and casting processes, manufacturers can achieve much tighter tolerances than traditional pattern making, allowing architects and designers to create highly detailed and innovative designs.

Architectural castings can be fabricated as standard as well as custom ceiling and wall applications, column covers and moldings, allowing for the replication of highly detailed and creative designs.

Architectural casting manufacturers utilize state of the art computer numerical controlled routers in their model making process. This allows for extremely tight and accurate tolerances, making highly detailed castings possible. Architectural castings are available in traditional forms and styles such as columns, moldings, domes, and cupolas, and can be customized to virtually any shape. This allows architects and designers to create complex and innovative designs limited only by their imagination. Architectural castings are made from composites that are lighter than conventional building materials and require little or no maintenance.
