Steel buildings are made primarily from steel materials. This material is an alloy that is made up of iron and has carbon content that ranges between . 2 percent and 2.1 percent by weight. Content amount depends upon the grade of the material. Buildings that use this type of material are hoping to establish a strong internal support or exterior cladding. These types of structures can be used for a variety of purposes such as office and living spaces or storage facilities.

Buildings made from steel became popular during the 20th century. They were widely used during World War II and even more when the alloy became more accessible. Some of the popularity is attributed to the cost efficiency. These buildings are often easy to build and maintain. Improvements in products, materials, design and computer technology has led to the high demand.

The many advantages of these units add to their appeal. They are known for being high quality- strong, durable and stable structures. They are considered easy to maintain, especially in regards to finances. The materials needed to construct the framework are less expensive than other materials and maintenance costs are generally low. These structures are environmentally friendly and termite resistant. Construction is usually simple and fast. A major advantage is that steel is non-combustible, that is, it does not catch fire and will not burn easily. This may be why individuals looking for storage facility opt for this material.

Disadvantages are few but should be noted. Heat conductivity can be a problem. Steel conducts 310 times more heat than wood. Depending on location and building use, this can be an issue. Another disadvantage is that the material is subject to corrosion. The corrosion of the iron and steel that makes up the framework can bring about issues.

There are different types of these structures. Two common characteristics: arch and straight-walled. These characteristics concern the outside shape. An arch can be more cost effective. It is commonly used within the agricultural industry. Straight-walled provides more usable space than arches and can blend into surrounding architecture. It is commonly used on commercial or industrial facilities.

Two other structural classifications: multiple span and clear span. Span refers to the internal structure of a facility. A clear span uses overhead support beams. This reduces the need for internal support columns. Clear spans are more practical for places where obstructions are not desirable. For example, sports arenas and aircraft hangers.

Overtime, the elements that make up these structures have evolved. In modern times, smaller structures are often prefabricated and easily constructed by virtually anybody. Larger buildings are also prefabricated. Though they must be constructed with safety and accuracy.

There are five main components of these structures. They are: tension, compression, combined-force and bending members and their connections. The members each have specific applications and serve different, but important purposes. Connections bring the building together. They connect all of the members together. When construction is complete, all of the pieces should function properly and do so as one unit.
