How much maintenance does a steel hangar require?

Steel buildings are virtually maintenance-free. Every building has natural wear and tear, but a less durable material such as wood will deteriorate at a much faster rate than steel. As a facility deteriorates, maintenance is less likely to keep pace, contributing to less structural integrity and increasing the chances of permanent and dangerous damage. Steel hangars are less likely to get infested by pests, mold, and the structure will not rot like wood buildings usually will over time.
