When deciding whether to construct a building from metal or other materials, business owners frequently consider the project, utility and maintenance costs. However, they often don't think about the work that rebuilding after a flood would require. Business owners in Corpus Christi should take into account how the building would fare in a flood — metal buildings do particularly well in this area.


Certain metals including plain steel, corrode when they come into direct contact with water. However, the material used in metal buildings is designed to not rust for many years.

Most metal buildings are made from galvanized steel. Galvanizing covers the steel with a layer of zinc. This layer forms a barrier between the steel and any water, preventing the steel from rusting. Zinc doesn't corrode when it comes into contact with water.

Galvanized steel protects metal buildings from rainwater, sleet and snow. It also safeguards steel from floods. It doesn't matter if water is coming from above or from below, the layer of zinc will stop the water from contacting the steel and causing corrosion.


Unlike wood, sheetrock, mortar and other building materials, metal doesn't absorb water. In a flood, water will pile up against the building and then flow away. A few droplets may remain on the metal, but these either dry on their own or are easily wiped away.

Because metal doesn't absorb water, it has several advantages over wood, sheetrock, mortar and similar materials that do absorb water:

  • Metal doesn't rot
  • Metal doesn't need to be replaced
  • Metal dries faster

In short, metal requires less recovery work after a flood and reduces the repair work to be done.


Because metal isn't organic, doesn't have pores and doesn't absorb water, it resists mold and mildew growth. Mold and mildew can grow on metal, but steel is a lot less susceptible to these pathogens than wood, sheetrock and similar building materials. Metal has fewer places for mold spores to land, and it doesn't retain moisture that can lead to mold and mildew growth.

This advantage alone can greatly reduce the cost of reconstructing a building that's damaged in a flood. Removing all mold and mildew that grows often accounts for a large portion of a company’s flood recovery expenses. By controlling how quickly and easily mold and mildew can grow, businesses can cut down on removal costs and reconstruction expenses.


Since metal has a smooth surface, there generally aren't any places for flood waters to seep between a metal wall and the paint that's on the metal. In contrast, flood water might get into wood's pores, and it can easily get under vinyl siding as flood levels rise.

Once water gets into a wall's building materials, it can destroy the wall's paint. Drop by drop, water can seep between the wall and paint, slowly separating the paint from the wall. The result is often peeling paint which looks unsightly and is prone to chipping. The paint must then be removed and the wall has to be repainted.

This isn't a problem with metal, so there's no need to have metal building exteriors repainted after a flood. The resulting savings are significant, for it's often not possible to paint just a part of a wall. If just the bottom foot of a wall is peeling and needs repainting, then the whole wall usually has to be painted because the old paint will appear faded next to the new one.
