These fittings are mill-duty steel fabrications for dry bulk material handling: spouting, valves, slide gates, adjustable spout ends, and industrial ductwork for air and dust systems. Construction uses laser cutting, high-definition plasma, computerized rolling, automatic seam welding, press brakes, and stamping so parts match the spout and gate patterns used throughout the grain industry.
Technical Specifications
Sizes are outside-diameter (round) or outside width (square) unless noted. Select diameter/size, gauge, lining, and finish on this page; price, weight, and freight cube update with the option set.
Rack-and-pinion / roller slide gate. Standard slide gates are 5-1/2" tall. Standard ceiling gate: 10 ga frame, 7 ga slide traveling on keystock. Ceiling roller gate: 2" high-density plastic rollers that do not rust. Premium gate: 7 ga frame, 1/4" slide, steel bearing races, shaft and sleeve bearings. Cast rack is 1-5/8" wide; pinion is cast steel, 2-7/8" diameter, 10-tooth, 1" bore (7-1/2" of rack travel per revolution). Weather covers for the rack-and-pinion pocket add about 50–69 dollars and a few pounds depending on size. Dust hoppers (height = gate opening) can be added to contain fines. Electric travel: actuator drives ≈ 2.8 in/sec; gear-head drives <24" ≈ 3.0 in/sec; 24" and larger ≈ 1.8 in/sec. Approximate shipping size for a 12" premium roller gate: 36" L × 18" W × 10" H.
Construction. Laser-cut and plasma-cut carbon, galvanized, or 304 stainless from 14 ga through 1/4" plate. Seams welded; flanges punched to the standard patterns used on this product family. Custom hole layouts are available. Typical capacity guidelines use ~70 BPH per square inch of interior area for 8" and larger spouts on clean corn, soybeans, or wheat at 40° or greater. Target grain velocity under 1,750 FPM to limit kernel damage and premature wear .
Available option families include diameter/size (commonly 4"–24", some gates to 36"), gauge (14, 12, 10, 7 ga, 1/4" wall), lining (none, 7 ga AR, 1/4" AR, blue urethane, orange urethane, ceramic-chip urethane, ceramic tile), and finish (primed gray, galvanized, stainless).
Capacities assume clean, dry whole grain at 40° or steeper. Wet corn should be spouted at 45° minimum. Lining and fittings reduce capacity. Use these figures as planning guidelines and confirm the selection for your application before you order.
