Hurricane and Storm Resistant Steel Buildings

A building withstands a hurricane when its whole structure is engineered to the design wind speed at its location and tied together with a continuous load path from roof to foundation. Pre-engineered steel buildings do this well: the rigid steel frame is a single engineered system, the roof and wall panels are specified to resist wind uplift, and the connections and anchor bolts transfer load into the foundation. What matters is not the material alone but that the frame, envelope, connections, and openings are all designed to the wind pressures the building will actually see.

Yes. A metal building is hurricane resistant when it is engineered to the correct wind load for its site rather than built to a generic standard. We calculate the design wind speed and exposure category under ASCE 7 and the applicable building code, then size the frame, bracing, panel gauge, fastener pattern, and anchor bolts to those forces. Older metal buildings that failed in past storms were typically under-designed or poorly connected. A modern pre-engineered building designed to the right wind load with a properly detailed load path performs reliably in high winds.

Yes, a structure can be engineered for very high wind speeds, including those associated with the strongest hurricanes, though the design becomes more demanding as the rating rises. The frame, connections, panels, and foundation all have to be sized for the higher pressures, and openings need impact-rated protection. The target wind speed is set by the building code for your location and exposure, and the structure is engineered to meet it. We design each building to the specific wind requirements at its site rather than to a single fixed number.

Steel buildings perform well in hurricanes when they are engineered to the correct wind load, because steel's strength-to-weight ratio lets the frame carry high uplift and lateral forces across a wide clear span, and steel does not rot or weaken with age in a wet, salt-laden coastal climate. The key is engineering and detailing: the continuous load path, the roof and wall fastening, and the anchorage all have to be designed to the site's wind pressures. Engineered correctly, a pre-engineered steel building is a strong choice in a hurricane zone.

The wind speed a building is rated for is set by the building code for its location, based on local wind maps and the exposure of the site, and it varies widely between an inland location and a high-velocity coastal zone. Coastal Florida, the Gulf, and Caribbean sites carry some of the highest design wind speeds in the country. We engineer each building to the design wind speed and exposure category that apply at its site under ASCE 7 and the applicable code, and supply engineered structural stamped drawings showing the loads the structure is designed to.

Cost depends on the design wind speed, the size, the openings, and your local code loads, so a hurricane resistant building is quoted per project rather than as a flat figure. Engineering a building to a high coastal wind load adds material and detailing compared with the same footprint inland, but a code-engineered steel building also resists the storm damage and corrosion that drive long-term costs in an exposed location.
