Steel doors are strong and durable entryways made primarily from steel. They are commonly used in commercial buildings, warehouses, and industrial settings due to their resistance to impact, weather, and fire. Steel doors can also provide enhanced security, making them a popular choice for areas that require protection against unauthorized access. In addition to their strength, steel doors can be designed to fit various aesthetic preferences. They come in different styles, colors, and finishes, allowing them to complement the architecture of a building. Many steel doors also feature insulation, improving energy efficiency and soundproofing in both residential and commercial spaces.
