The Premier Source for Angle Rings

Our angle rings represent innovative manufacturing at its finest. For industrial facilities, circular ductwork allows for increased efficiency, faster installation, and higher tolerance for medium to high pressure airflow. Rolled angle rings provide for the sturdy connection of circular ducts to create the large-scale ductwork systems that industrial facilities need. At Haltom Industries, we maintain a large on-hand inventory of rolled angle rings. Our angle ring products are lightweight, highly versatile, and available in any diameter you need. Whether you need connectors for your ductwork, support for fan housings, or mounts for piping transitions and elbows, our angle rings are second to none.

We maintain a constant and extensive inventory of angle rings ready for immediate shipment to clients located anywhere in the United States. If we do not have your precise measurements in stock, we can also create custom angle rings of any size. Our smaller rings, those with a diameter of 14 inches or less, are manufactured through a proprietary stamping process. This innovative manufacturing strategy allows us to offer a top-tier product at an unbelievable price. We manufacture larger rings through our custom metal rolling procedure. These rings benefit from heightened durability and true 90-degree angles, which provide for exceptional strength and a tight fit. Suitable for use in any environment, we manufacture hardy products that can withstand just about any hazard. To learn more about our angle rings or place an order, call us today at 817-770-0811.

As a connector solution, angle rings provide important benefits. Typically used to connect lengths of spiral seam or welded pipe, an angle ring allows for a clean connection with no impedance from bolts or screws that protrude into the flow of air. At Haltom Industries, we proudly offer angle rings of any size requirements, in quantities that range from a single prototype, to the thousands needed in the largest of manufacturing facilities. We can also electroplate or hot-dip galvanize any custom or standard angle ring for added durability.
