Portable metal buildings are portable buildings that are made of metals without using any wood. Even though steel is not a metal, portable buildings made from steel are considered part of the category of portable metal buildings.

Most of the portable metal buildings are made from a thick gauge of steel or aluminum. Typically, there would be no exterior wood to these structures. These metal buildings are built to be extremely strong, and they do not shake or rock when one walks inside them.

While seasonal needs are a major reason for preference of portable buildings over permanent buildings, the general cost effectiveness of such structures has contributed to their growing use and popularity. Installing portable metal buildings is an effective way to avoid spending money on setting up expensive permanent buildings. Since there is no need for a concrete base, construction costs are significantly lower with portable metal buildings than with permanent buildings. Moreover, these buildings have almost a zero-maintenance feature, and there is no need to be concerned about permanently losing yard space.

Portable metal buildings are made for both domestic and commercial applications. They are commonly used for storage purposes, though other uses are not uncommon. For example, a portable metal building can be used in houses for storing electrical and communications equipment, while commercially, these buildings can be used for storing construction equipment. Their construction helps them handle the fury of nature, particularly hurricane-force winds, heavy rains, and blizzards.

An industry that makes major use of portable metal buildings is the construction industry. These strong and sturdy buildings provide protection from burglary while offering flexibility in moving them from one construction site to another. Based on the size, these portable metal buildings can be moved using a forklift or a crane, even when they are packed with materials inside.
