Features and benefits
Durability
Steel doors are built to be strong and are resistant to warping, cracking, and weather conditions.
Security
They offer high security against forced entry and can provide a fire rating of up to 3 hours.
Energy efficiency
The foam core helps to reduce heat transfer, which can lower energy costs.
Versatility
Steel doors can have a smooth finish for painting or a textured finish that mimics natural wood.
Low maintenance
They require minimal upkeep and can be repaired with products like an auto body repair kit for minor dings and dents.
Construction
Outer and inner layers
Two sheets of galvanized steel form the door's skin, with a steel edge perimeter for added strength.
Core
The steel sheets sandwich an insulated core made from materials like polyurethane or polystyrene for energy efficiency.
Gauge
Steel gauge refers to the thickness of the metal; a lower gauge number indicates a thicker, more durable door (e.g., 20-gauge is thicker than 24-gauge).
Lock block
A composite lock block is often included for stronger, more secure hardware installation.
