We are also one of the few acclaimed names to offer aluminium couplings that are highly flexible in nature and require less maintenance. Featured with constant velocity, they are dense coated and are formed by converting the surface of the aluminium alloy into a hard aluminium oxide. The coating resists abrasion and corrosion. This is the standard grey finish on all extruded lightweight couplings. Our Aluminum couplings are available with powder coated colored finished and/or with bar code notch for tracking purposes.
