Steel doors are durable, secure, fire-resistant, and weatherproof barriers made from a steel coating over an insulating core like honeycomb or polyurethane, providing enhanced protection and security for both residential and commercial buildings. They offer superior strength to other door materials, resist termites and rust, and can be finished with wood-like aesthetics or various colors, making them a versatile and cost-effective choice for various applications.
Construction and Materials
- Steel Skin:A thin, strong layer of steel forms the exterior and interior surface of the door.
- Insulating Core:A honeycomb structure or a solid core of material like polyurethane or polystyrene fills the space between the steel skins. This core provides insulation, sound reduction, and impact resistance.
- Reinforcement:Internal steel reinforcement in specific areas adds strength, especially where hardware like locks is mounted.
Key Features & Benefits
- Durability:Steel doors are inherently strong, resistant to rust, and can withstand significant abuse, offering superior performance compared to other materials.
- Security:The inherent strength of steel, combined with features like impact-resistant cores and advanced locking systems, makes steel doors a strong deterrent against forced entry.
- Fire Resistance:Steel doors can provide fire protection, helping to contain flames and heat, making them ideal for safety in various buildings.
- Weatherproof & Pest Resistant:They are resistant to environmental factors such as water, heat, and humidity, and also provide protection against termites and bacteria.
- Aesthetics:While strong, steel doors can be manufactured with finishes that mimic the look of wood or come in a range of colors to suit different architectural styles.
- Insulation:The core materials, such as polyurethane or honeycomb, provide thermal insulation, contributing to better energy efficiency in a building.
Common Applications
- Residential: Main entrances, bedroom doors, and bathroom doors.
- Commercial & Industrial: Due to their robustness, they are frequently used in industrial and commercial settings.
- Specific Institutions: Their antibacterial properties make them suitable for use in hospitals and schools.
