Simplicity Meets Sophistication | Swing Door Hardware Showcases the Charm of Diverse Lifestyles with Exceptional Quality

In modern homes and buildings, swing doors are widely used. Whether in residential homes, commercial offices, or public spaces, the performance of swing doors relies heavily on the support of high-quality hardware.

Leveraging over 40 years of technical expertise, 3H Building Hardware provides professional, high-standard hardware solutions for various types of swing doors.

Swing doors can be categorized based on materials into wooden doors, glass doors, and steel doors, each with distinct hardware requirements. These doors are widely used in hotels, schools, hospitals, airports, supermarkets, shopping malls, residences, and apartments.

1.Wooden Doors
Ideal for dry, private spaces, wooden doors effectively block noise, provide insulation, and offer environmental sustainability and stability. They adapt to various décor styles while demonstrating excellent resistance to deformation and wear.

2.Glass Doors
With transparency as their core feature, glass doors have evolved in materials and functionality to seamlessly fit into residential, commercial, and public settings, showcasing remarkable adaptability.

3.Steel Doors
Steel doors typically offer fire resistance, smoke prevention, corrosion resistance, and anti-theft properties. The hardware used must withstand high temperatures, resist corrosion, and prevent forced entry.

When selecting swing door hardware, quality and brand are crucial. 3H Building Hardware’s swing door products are designed for durability and smooth operation, effortlessly meeting the demands of diverse spaces.

Lock Body
Lock bodies are categorized by standards into Chinese, European, American, and Australian types, each with distinct specifications. Functionally, they include entry lock bodies, passage lock bodies, bathroom lock bodies, night latch bodies, classroom lock bodies, utility lock bodies, and emergency exit lock bodies.

As the core of a door lock, the lock body executes operational commands, drives bolt movement, provides anti-theft structures, and enables automatic locking and deadbolting. Its quality, structural design, and compatibility determine the lock’s security, smooth operation, and reliability.

When selecting a lock body, consider its functionality, anti-theft level (bolt type, multi-point linkage), material quality, size compatibility, and alignment with the door and handle hole spacing.

Handle
Handles are categorized by design into separated and integrated types, and by material into stainless steel, zinc alloy, aluminum alloy, copper, and nylon. As the visible part of the hardware system, handles must balance functionality, security, and aesthetics.

Choose based on usage scenario, style preference, and material performance, and ensure strict adherence to installation standards for long-term reliability. For special needs (e.g., high humidity, fire resistance), stainless steel is recommended.

Lock Cylinder
Common lock cylinders, such as European-style dimple, American-style pin, Australian-style oval, and padlock cylinders, all operate on the pin tumbler principle. The key’s ridges precisely align the pins inside the cylinder, allowing it to rotate. With advancements in technology, lock cylinders have become more intricate, significantly reducing the risk of unauthorized access.

According to Chinese standards, lock cylinders are classified into three levels:

Grade A (low security, vulnerable to technical manipulation)

Grade B (medium security, resists technical manipulation for about 5 minutes)

Grade C (high security, resists technical manipulation for ≥10 minutes)

Select the appropriate grade based on the scenario. For example, Grade C is recommended for entry security doors.

Door Closer
Door closers (also known as automatic door closers) are widely used in architectural doors and windows and can be categorized into electric and mechanical types. Their primary function is to ensure doors close automatically, smoothly, and controllably after opening, addressing energy efficiency, fire safety, and smoke prevention while protecting the door structure and ensuring user safety.

Door closers can be surface-mounted or concealed. Selection depends on door weight and width → functional requirements (e.g., fire resistance, location, environment, frequency of use) → installation method.

Hinges
Hinges are essential hardware for various types of swing doors, connecting the door frame to the door leaf (or window frame to window sash), enabling smooth rotation, bearing weight, and preventing sagging.

Hinge types include surface-mounted hinges, concealed hinges, rising hinges, security hinges, spring hinges, 3D adjustable hinges, multi-point hinges, and special hinges. Though small, hinges play a critical role in door security, stability, smooth operation, and overall aesthetics.

Selecting the right hinge requires considering door type, usage environment, functional needs, and budget. High-quality hinges and proper installation ensure long-lasting, stable, and smooth performance. Different scenarios may require different hinge types.

Automatic Door Bottom Seal
Approximately 25% of building energy loss occurs through doors and windows. To improve energy efficiency, automatic door bottom seals are installed at the base of doors, providing benefits such as energy savings, sound insulation, dust prevention, smoke sealing, fire resistance, and insect protection.

Whether for homes, commercial offices, or public spaces, choosing reputable brands is key to ensuring hardware quality.
