Iron Age Designs provides decorative drain grates, tree grates, and other architectural castings, both standard and custom, for public and residential use. Our standard decorative trench grates fit the most widely used drain bodies and trench drain channels made by major manufacturers such as ABT™, ACO™, MEA™ and NDS™. Iron age trench grates can be retrofitted into existing installations or be purchased at the time of the original installation. We also offer custom architectural castings in cast iron, aluminum, ductile iron and silicone bronze. All of our castings are made from recycled product and are ADA compliant.

What makes Iron Age grates different from the typical drain grate?
Humble and forgotten, the typical drain has long been overlooked as a design element. Most commercial drain grates are strictly utilitarian in style. Perpendicular lines and plastic are commonplace, and have come to be what’s expected in the marketplace. In many cases, the drain grates look like an afterthought, or even clash with the design.

Iron Age offers a wide range of pattern options that will complement your design efforts and the materials of the surrounding surfaces/landscape. Our grates are made with sculptural relief, in contrast to the perfectly flat surfaces of other grates. The unique designs and dimensional surfaces create visual interest, elevating the drain grate to an artistic focal point.

What materials and finishes are available?
Iron Age offers a variety of materials and finishes that each have their own unique properties. Some of the most common materials we work with are Bronze, Aluminum, Ductile Iron and Grey Iron. Finish options include Baked-On-Oil and Powder Coating.
