DOOR FRAMES
Overview:
Steel door frames are an essential part of modern construction, offering unmatched durability, security, and versatility. Used in residential, commercial, industrial, and institutional buildings, steel frames provide a solid foundation for doors of various types and materials. With their robust structure and ability to withstand wear and tear, steel door frames are a preferred choice for both interior and exterior doorways.
What Are Steel Door Frames?
-
Steel door frames are fabricated from mild steel sheets, galvanized iron (GI), or stainless steel, depending on the application. They are designed to house and support doors—either metal, wood, or composite—while maintaining structural integrity and alignment. These frames can be manufactured in various profiles, such as single or double rebate, flush type, or fire-rated, to suit specific door configurations.
-
Steel frames are available in knocked-down (KD) form for easy transportation and on-site assembly, or as welded units, which are fully assembled and ready for installation. Standard thicknesses range from 1.2 mm (18 gauge) to 1.6 mm (16 gauge), although thicker sections can be used for security or industrial-grade applications.
Key Benefits
1. Strength and Durability
-
Steel is inherently strong and capable of withstanding extreme environmental conditions, heavy usage, and mechanical impact. This makes steel frames ideal for high-traffic areas such as public buildings, hospitals, and educational institutions.
2. Fire Resistance
-
Many steel door frames are tested and certified for fire resistance, typically rated for 1 to 3 hours depending on the construction. Fire-rated steel frames help prevent the spread of flames and smoke, protecting both life and property.
3. Corrosion Resistance
-
With proper coatings such as galvanization, powder coating, or painting, steel door frames can resist corrosion and rust, ensuring long-term performance even in humid or coastal environments.
4. Security
-
Steel door frames provide excellent resistance against forced entry, making them suitable for security-sensitive applications such as banks, data centers, and secure facilities.
5. Low Maintenance
-
Unlike wood, steel does not warp, crack, or attract termites. It requires minimal maintenance, making it a cost-effective choice over the long run.
Applications
-
Steel door frames are widely used in:
-
Residential buildings (main doors, utility areas)
-
Commercial spaces (offices, shops, malls)
-
Industrial setups (factories, warehouses)
-
Institutional buildings (schools, hospitals, government offices)
-
They are also commonly paired with metal doors in fire exits and escape routes, as part of building safety standards.
Conclusion
-
Steel door frames offer a combination of strength, safety, and sleek appearance that makes them suitable for a wide range of applications. Whether you are building a modern home or a multi-story commercial complex, choosing steel frames ensures long-lasting performance, security, and peace of mind.
