Steel doors, also known as steel doors or metal doors, are made of cold-rolled steel sheets through a series of modern processing techniques. They are not simply a piece of iron, but a well-structured system.
Strong Fireproofing and Flame-Retardant Properties
Many steel doors (especially entrance doors and fire-rated doors) meet national fire ratings (such as Class A, Class B, and Class C). They can effectively block the spread of fire and high temperatures in the early stages of a fire, buying valuable time for evacuation and fire rescue.
Excellent Soundproofing and Thermal Insulation
The honeycomb or bridge-hole mechanical structure within the door effectively blocks and absorbs sound waves, reducing noise transmission.
The steel material and internal structure together form a highly airtight structure, helping to maintain indoor temperature and conserve energy.
Diverse Aesthetics and Decorative Features
Various Appearances: Using advanced transfer printing technology, the door can realistically simulate the grain and texture of various precious woods, such as walnut, oak, and cherry, to meet the needs of various decor styles (modern, minimalist, Chinese, and European).
Diverse Color Options: In addition to wood grain, a variety of solid colors (black, white, gray, etc.) and special colors are available, making it easy to coordinate with indoor and outdoor environments.
Easy to Clean: The smooth surface resists dust and can be cleaned with a damp cloth, making maintenance simple.
Highly Cost-Effective and Environmentally Friendly
Affordable: For comparable performance (such as security and soundproofing) and appearance, steel doors are generally less expensive than solid wood doors.
Environmentally Friendly Materials: Steel, the primary material, is recyclable and reusable, eliminating the need for timber logging and embracing environmental sustainability. The coatings used in the production process are also primarily environmentally friendly.
