    Common Questions

    Yes. Our professional steel building contractors are available to help manage and erect your entire steel building.

    One of the most popular steel building questions we get is “How much does a steel building cost?” A steel building cost is primarily based on size, engineering, and options.

    Let’s break down the price a little. If we look at the size of your steel building, for an example if it is 30x50x10, so we have a 30 foot wide, 50 foot long, and 10 foot high building. 

    This size of a building is going to be cheaper than a 30x80x10 of course. Where a steel building price gets a large difference in price is the length. It takes a lot more metal and engineering for say a 100′ foot wide building compared to an 80′ foot wide building. A clear span building width takes a lot more engineering and so the steel building price will vary on this.

     This leads us into the engineering portion of steel building costs. You may find a cheap steel building price or a low price and wonder why is it so low? Well sometimes you may see that a steel building cost seems too good to be true, well it might be. For an example, a steel building may be engineered for say a 10lb snow load where you need a 40lb snow load. This is the most common reason for low prices. An advertised building price may not be engineered for your area. So as you search for steel building prices, make sure you ask about snow loads, wind speeds, and building codes.

    Lastly, we need to factor in options. Do you need a steel building contractor? Do you need a turnkey project? What about a concrete floor, windows, doors and metal building insulation? Every option add additional cost to your steel building prices.Do we 

    Yes. We sell not only prefab steel buildings, but we also sell engineered metal building kits.

    Yes. No matter if you need a spacious metal building home or a steel building cabin, we can provide you with a custom steel building home kit or offer construction solutions.

    A residential steel building is a steel building type or design that would be erected at a residential location. We typically see these types of steel framed structures as metal garages, pole barns, rv storage, and other home related steel construction.

    A prefab steel building or prefabricated steel building is a steel building that is engineered and then prefabricated to be able to be erected and assembled with ease. So the steel building company orders from a steel building manufacturer, then the steel building designer takes the engineering for the location of the final product such as the snow load requirements, wind speed requirements, and various other building code needs, then prefab a steel building that will then be shipped by the steel building company or metal building distributor to the customers job site or home.
