South Carolina Metal Buildings

When selecting a metal carport or steel building in South Carolina, it’s important to factor in the state’s diverse and often extreme weather conditions. Whether you’re installing a prefab garage in Greenville, an RV cover near Myrtle Beach, or a commercial metal warehouse in Charleston, your structure must be engineered for South Carolina’s unique climate.

1. High Humidity & Coastal Moisture

• Much of South Carolina—especially coastal cities like Hilton Head, Charleston, and Beaufort— experiences high humidity and salt air.
• Galvanized steel buildings and rust-resistant framing upgrades help prevent corrosion in these regions.
• For enclosed metal garages or workshops, adding ventilation systems or insulation can minimize internal condensation and protect valuable equipment.

2. Heavy Rainfall

• South Carolina receives over 40 inches of rain annually, with peak rainfall during hurricane season.
• Vertical roof metal carports and A-frame steel buildings are recommended for optimal water runoff.
• Adding gutters and downspouts improves drainage and preserves foundation integrity on your metal structure.

3. Wind Loads & Storm Protection

• Along the South Carolina coastline, wind load requirements often exceed 130 mph, especially in hurricane-prone zones.
• All Pro Metal Buildings are available with wind-rated certification, reinforced framing, and anchoring systems designed to meet or exceed local and state building codes.
• Customers in areas like Columbia, Summerville, and Conway should prioritize wind-resistant metal garages and commercial structures.

4. Heat & UV Exposure

• With long, hot summers and high UV exposure, South Carolina structures benefit from premium roof coatings and paint systems that prevent fading and surface breakdown.
• For added comfort and energy efficiency, consider insulated metal buildings—ideal for home offices, garages, or agricultural applications in the Midlands and Upstate regions.

Recommended Steel Structures for South Carolina:

• Steel carports (regular, A-frame, and vertical roof styles)
• Fully enclosed metal garages with roll-up doors
• Boat and RV covers for coastal properties
• Commercial steel buildings up to 100’ wide with no limit on length
• Custom prefab barns and utility buildings
