Steel buildings have proven themselves to be durable and strong, useful for commercial and agricultural buildings or for freestanding garages and sheds on residential lots. However, some people have concerns as to the safety of steel buildings and whether or not they are and efficient means of construction. They are usually less expensive than traditional stick built buildings and when designed and constructed properly, are every bit as safe.
Assembling the Building
Assembling a metal building has many of the same hazards as any construction site presents without adding any dangers specific to the methods used while putting the building together. Most of today's metal buildings come in parts which are light enough for a team of workers to put in place without the use of heavy machinery, and then simply bolt together. As always, there is a chance someone may fall from a ladder or scaffolding, or trip on debris, but there aren't heavy power saws in use or other equipment and machinery being run on-site.
Using the Building
Being made of steel, metal buildings are are strong enough to withstand any weather in North America and arguably even give more protection against a falling tree than a traditional wood building. The real question some people ask about steel buildings is how safe they are during a thunderstorm. Although it might seem as if the metal would attract lightning, it actually is properly grounded and is less likely to attract a lightning strike than other buildings with electric wiring and plumbing systems running through them.
Metal buildings are every bit as safe as any other building and arguably safer. The fact of the matter is, if they weren't safe they wouldn't be allowed by local building codes. You may have other reasons for choosing a different material for your building, but don't let the idea of metal buildings being unsafe affect your final decision.
