Why Buildings Have Different Door Types

 A Constructor’s Story
When I first joined Golden Brick Constructions Ltd, I was amazed at how much thought goes into choosing a door. It wasn’t just about opening and closing—it was about function, design, safety, and comfort. Every building, whether residential or commercial, tells a story through its doors, and every constructor knows the secret behind each selection.

One morning, our lead constructor, Mr. Liang Wei, stood in front of a group of new workers at a site in Shenzhen. “You see these doors?” he said, pointing to a pile of different frames. “Each one has a purpose. A door isn’t just an entrance it’s a statement of what’s behind it.”

He explained that in modern construction, door selection begins at the design stage. For instance, wooden doors are preferred for bedrooms because they provide warmth, privacy, and good sound insulation. On the other hand, steel doors are often used for main entrances because they offer high security and durability. Kitchens and bathrooms mostly have PVC or glass doors, as they resist moisture and are easy to clean.

Liang smiled and continued, “When we design luxury apartments, we use solid oak or teak doors from Holike Door Company, one of China’s trusted brands. But for corporate buildings, we often order aluminum or glass sliding doors from OUPAI Doors and Windows Co. Ltd, a company known for its modern, lightweight designs that bring in natural light.”

He opened a catalog showing products from TATA Wooden Door Co., a well-known Chinese manufacturer based in Beijing. Their doors, he explained, are built using advanced noise reduction technology perfect for offices, hotels, and homes near busy streets. “TATA,” he said, “has become the pride of China’s interior door industry.”

During one of our projects a hospital construction Liang selected fire-rated steel doors from PanPan Door Industry, a Chinese brand famous for security and safety doors. “Hospitals, schools, and public buildings need doors that can protect life in emergencies,” he said. “Every choice here is made with a purpose.”

He walked us through the corridors of the almost-finished building, pointing out how the color, handle type, and even the swing direction were matched to the user’s needs. “Notice the ICU doors,” he said softly, “automatic, wide, and silent. That’s not luxury it’s necessity.”

By the end of the day, we all realized that doors tell silent stories. They represent culture, purpose, and design. The constructor’s art lies in knowing when to choose elegance, when to choose strength, and when to combine both.

Today, when I walk through a new building, I no longer just see doors—I see decisions, creativity, and craftsmanship from Chinese brands like TATA, OUPAI, Holike, and PanPan, each helping constructors like Mr. Liang build not just walls, but experiences that welcome every visitor in a special way.
