Steel America has a robust resume stacked with gate projects that have been completed safely and with high-quality craftsmanship. From bulkhead gates in the Midwest, to the largest sector gates on the Hurricane Katrina flood wall in New Orleans, Steel America has become a leading expert in gate fabrication.
Gates come in all different shapes, sizes, materials, and each type of gate serves its own unique purpose. Some block off roadways during disaster evacuations (roller gates), some hold back rivers in a dry dock so shipyards can repair the hull of a naval vessel (caisson gates), and some control water flow in a canal (tainter gates).
Our most recently completed gate project was in 2016, where Steel America fabricated one new Emergency Reservoir Drainage System Bulkhead Gate for the Strontia Springs Dam in Douglas County, Colorado. The project consisted of detail design, fabrication, welding, machining, assembly, and painting of a 14′-6″ wide x 18′-2″ tall steel and stainless steel bulkhead gate assembly. The gate was fabricated in two sections with bolted connections for ease of transportation. After all welding was completed, each section was sub-harmonic vibratory stress relieved. The gate was fully assembled and inspected for flatness and dimensional tolerance prior to shipment to the site. It utilized the use of a 2″ thick skin plate with horizontal and vertical stiffeners to withstand a differential hydraulic head of over 215 ft.
