Barnmaster Barns/Buildings Specifications
A few good reasons why in the history of Barnmaster, there has never been a structural failure.
1. Standard walls are constructed using ¾" CDX plywood core with 26 gauge zincalume plus steel laminated to one side and 26 gauge zincalume plus embossed steel with SMP baked enamel finish in a variety of colors, laminated to side number two. Panels are then welded into a 2" x 1 ½" 55,000 KSI G-90 galvanized steel framework forming an 8' high x 12' long wall. The standard Barnmaster wall system has passed rigorous ICC testing for structural integrity (ER-5887) and carries a Life-Time Kick-Thru Wall Warranty.
2. The plywood cores and sheets of steel are laminated and vacuum bonded together using Rohm Haas urethane based adhesive.
3. Sliding grilled stall doors are constructed to match stall front. Galvanized steel door track has two, four wheel trolleys with sealed ball bearings that suspend the door in the door track. Two, galvanized heavy steel formed, door guides direct the door, one on each side of the door opening. Plated steel door latches and door stops are used to secure stall doors.
4. Stall front and door grills are constructed using 1 3/8" 17 gauge galvanized steel tubing spaced 2" 1/8" between bars. The grill plates are punched and 1 3/8" 17 gauge tubing is inserted into the hole and welded on the underside of the grill plate.
5. A 2" x 1 ½" 12 gauge 55,000 KSI galvanized steel connector column is used to bolt stall walls together. Zinc plated bolts are used in the assembly.
6. Divider wall trusses are constructed using 14 gauge 2" x 3" 50,000 KSI galvanized steel tubing. Breezeway trusses are constructed using 14 gauge 2" x 3" 50,000 KSI galvanized steel tubing. Rafters are 14 gauge 2" x 6" or 14 gauge 2" x 9" 50,000 KSI galvanized steel tubing.
7. Minimum 6" x 2 ½" or 8" x 2 ½" G-90 galvanized steel 16 gauge 55,000 KSI C purlins are used for roof framing. Aligning C purlins to the slope of the roof maximizes the strength of the roof to sustain high winds.
8. Roofing is Energy Star 26 gauge R-Panel, 80,000 KSI zincalume steel with Kynar baked enamel coating, coming in a variety of colors and is recognized as the leading panel in the metal roofing industry. The roofing carries a manufacturers warranty of 25 years.
9. #12 self-taping zinc plated screws with Neoprene washers are used to secure the roof to the barn superstructure.
10. All welds are treated with cold galvanizing compound of 83% pure zinc dust, which protects the metal against rust and corrosion. USDA authorized.
11. All work shall conform to the latest edition of the IBC, A.I.S.C. or local building codes.
12. Barnmaster is a Certified Fabricator / Los Angeles Fabricators License # 1813.
13. Certified welders in accordance with A.W.S. specifications shall do all welding.
