Ours steel buildings are:

Low Maintenance – A steel building is easier to maintain and clean than structures made of wood or brick. And Heritage’s superior paint warranty guarantees against peeling, fading, chalking or cracking.
Energy Efficient – Proper insulation can save money on heating and cooling costs. With the right insulation, animals or livestock can be housed in a steel building.
Durable – Steel buildings do not rot like wood and can stand up to constant use and strong weather conditions, including wind, rain, snow, and seismic events.
Pest Resistant – Metal is not susceptible to termites and other destructive pests.
Fire Retardant  – Steel is not susceptible to fire hazards.
Less Expensive to Insure – Because of its superior strength and durability, as well as its resistance to fire and other natural disasters, your insurance costs may be lower if you choose a steel building over other materials.
