Frequently Asked Questions About Steel Buildings and Metal Garages
Is it cheaper to build with steel or lumber in South Carolina?
The labor costs of installing a steel structure or metal building are often reduced by 50% compared to wood construction. This is because steel components are pre-engineered and prefabricated, allowing for faster assembly on-site in Charleston and Summerville.
Additionally, metal buildings resist our coastal humidity, termites, and hurricanes better than wood – saving thousands in long-term maintenance. With current lumber prices, steel garages typically cost 30-40% less than traditional construction.
Are steel buildings worth it in Charleston’s climate?
Absolutely! Steel buildings and metal garages are an excellent investment for coastal South Carolina because they:
- Resist hurricane-force winds (our buildings are rated to 160 mph)
- Don’t rot or warp in humid conditions
- Termite and pest-proof
- Fire resistant
- Last 40+ years with minimal maintenance
- Lower insurance premiums than wood structures
For RV and boat storage especially, the protection from salt air and UV damage makes steel the smart choice.
Do steel buildings need a foundation?
Yes, steel buildings and metal garages require a proper foundation for stability and warranty compliance. Options include:
- Concrete slab (most common for garages)
- Concrete footers with gravel base
- Certified ground anchors for smaller structures
We handle all foundation requirements and include this in your quote for Charleston and Dorchester county installations.
What size metal building do I need for an RV?
RV storage buildings typically require:
- Class A Motorhomes: 14′ high x 12′ wide minimum
- Class C RVs: 12′ high x 10′ wide minimum
- Travel Trailers: 12′ high x 10′ wide minimum
- Add 3-4 feet to length for comfortable maneuvering
We recommend visiting our Summerville showroom to discuss your specific RV or boat storage needs.
