Steel support beams for residential building range in price from $100 to $400 per foot, or between $1,200 and $4,200. The more feet of beam you need, the more expensive they are. Beams are usually available in lengths that can be cut to size.
The first thing to understand about steel joists is that there are actually two types: cold-formed and hot-rolled. Cold-formed joists are thicker and stronger than hot-rolled ones, but they are also more expensive. Hot-rolled joists can be thinner and less expensive, but they aren't as strong.
The second thing to know is that while the average price of steel joists ranges from $10,000 to $20,000, this price includes all the components of the beam, including the headers and webbing. The actual material cost alone is only part of the total expense. In fact, hot-rolled joists are so cheap to make that some manufacturers will sell them at a loss if they believe it will help them compete with other brands. They do this by using cheaper materials for other parts of the beam, such as the header, where they know they won't be making much profit anyway.
A beam should be used in place of a load-bearing wall. The cost of installing a steel beam ranges from $1,300 and $5,000, depending on the size and kind of steel beam you pick, as well as the labor required to install it. A beam is the most efficient way to divide up a floor plan into smaller rooms. Beams can also be used to create open spaces within a room or between multiple rooms.
The first step in choosing the right type of beam for your home is to determine how much weight it will need to bear. If you're building a new house, this would be easy to figure out; but if you have an existing structure, weigh the available beams to make sure they can support their own weight as well as what kinds of loads you expect to put on them.
Next, look at the space where you want to mount the beam. Certain areas of a house (such as near heaters, air conditioners, and other heavy appliances) require special attention when mounting a beam. You may need to leave extra space beneath the beam to allow for plumbing or other utilities that could not otherwise be run under the beam.
Once you know where you're going to mount the beam, measure the distance between the outer edges of the supports you'll be using for it. This is called the bearing length.
Steel-framed dwellings range in price from $45,000 to $140,000, or $20 to $70 per square foot. This is a premade kit with components and instructions for basic assembly. You'll have to spend more for additional services, such as a foundation or insulation, to make it livable. Metal Shop House Costs include labor and material costs but not the completed house itself.
The total cost of building a metal house can be reduced by about 20 percent if you hire professional builders instead of doing it yourself. This includes electricians, plumbers, and other tradespeople who will need to work on site.
The average cost of building a custom home in the United States is $200,000. However, lower-cost options are available; for example, it would cost $45,000 to $60,000 to build a typical prefabricated house.
Building a metal house may be less expensive than building a wood house. The cost of materials alone for a metal house is usually higher than for a wood house, but the overall cost is less because it doesn't require any lumber at all. In fact, one metal house costs about the same as several wood houses.
The cost of building a steel house depends on how many square feet you need. If you plan to live there permanently, you should consider getting a prebuilt house because this will reduce your cost per square foot.
A 60x100, or 6,000 square foot, metal structure will cost between $108,000 and $120,000 for the steel construction kit alone, or $18–$20 per square foot. Add interior finishes and equipment (such as HVAC systems, lights, and sound systems) and you'll need to add another $35,000 to $40,000 or more for a total project cost of $145,000 to $155,000.
The average price of a wood building is about $250,000. The average price of a concrete building is about $350,000. The average price of a steel building is about $60,000.
Metal buildings are by far the least expensive form of housing with the average price of a 60×100 foot building being $180,000. However, they are also the most labor intensive due to the extensive assembly required when constructing them from scratch. In addition, metal buildings require constant maintenance and are not considered safe in some states if they aren't properly insulated.
Wood buildings are the most expensive form of housing with an average price of $250,000. They are also the fastest to build if you have access to a construction site. However, wood buildings require regular maintenance checks throughout their life to prevent any potential problems from arising.
In general, steel constructions are cost per square foot. A rigid-frame steel construction, for example, will normally cost $13 to $22 per square foot. A finished metal building costs more, ranging from $19 to $29 per square foot for a simple structure to $41 per square foot for a complicated construction.
The basic cost of steel is about $7 per pound, so a beam one hundred feet long would cost $700. However, structural steel is usually engineered to meet government requirements for strength and rigidity while being as light as possible. So the actual weight of the beam could be less than $700 if it uses thinner gauge material or if it's an I-beam instead of a T-beam. The same thing can be said for other types of structures: roofs, walls, etc. Thicker gauge material costs more but provides greater strength and stability.
Other factors that affect cost include the type of structure you want and its size. For example, a barn needs to be strong enough to support itself without any assistance from posts or beams inside the wall. This means it can have heavier gauge material than a house built on solid ground. Also, if the structure will be used for storage, you will need to buy enough material to make sure it's well-packed down inside.
Shape also plays a role in how much material you use. For example, a rectangle will use less material than a square of equal area.
