• Steel buildings bolt to a solid concrete foundation. A metal sheeting notch insures the building will be frost and flood proof.
• Solid steel framing is coated with a highly protective primer which is applied after all cuts are made and holes drilled, so there is never any breach in the rust protection. Steel does not warp and is guaranteed for the lifetime of the building. Steel is sanitary and nonpoisonous for livestock, and is preferred for permanent installation.
• Property insurance is 30% lower for a Twin I Steel Building system.
• Extensive assembly documents and plans are provided. All plans are engineer stamped and ready to be submitted to the building department. Twin I Steel buildings can be erected using nothing but scaffolding and hand tools. If you have to cut or drill out frames, you've got the wrong piece!! Are parts are numbered and guaranteed to fit.
• Once a Twin I Steel Building is up, it's up! You don't have to think about it for the next 20 years. After the pole barn has disintegrated (average 15 years) our metal building still has 5 full maintenance free years left.
• Class C fire rating -- Same as all masonry buildings. Our buildings are suitable in any zoning district and can be specified to meet or exceed the strictest earthquake, or any commercial codes in America.
• Poles are set directly into the earth and offer no resistance to flood and frost heaving.
• Pressure treated wood warps and shrinks. It's not recommended for permanent installations. Because the foundation frame members shift, pole barns must be straightened every 5-7 years at a current rate of $2500. Copper sulfate pressure treated wood poles with wooden purlins and grits are poisonous and unsanitary. They're not recommended for livestock...
• Property and fire insurance is 30% higher annually for wood barns.
• Usually no assembly documents, plans or blueprints are available. This usually causes problems when obtaining permits or assembling large or complex buildings. Parts are not usually numbered or sorted, causing assembly problems on even small pole buildings. Assembly involves "many hours" of tedious sorting, cutting and fitting of material.
• Pole barns must have sheeting reattached regularly and painted often. The steel being in contact with wood makes it more likely to rust. Most pole barns must be completely resheeted every 7-10 years, at a total current cost of approximately $16, 500 over a 15-year life span.
• Class A fire rating -- The lowest resistance to fire hazard. Pole barns are not recommended for public use. Pole barns meet only the most lenient code standards for permanent structures. They are prohibited in many zoning districts.
