A 50 x 76 mm stainless steel butt hinge is a heavy-duty, corrosion-resistant hinge commonly used for doors, cabinets, enclosures, and various industrial and outdoor applications. The butt hinge design consists of two rectangular leaves joined by a pivot pin, allowing for smooth opening and closing while providing reliable strength. The 50 mm x 76 mm size is ideal for medium to heavy-duty applications, offering more load-bearing capacity compared to smaller hinges.

Key Features:

1. Stainless Steel Construction:

   • Typically made from AISI 304 or AISI 316 stainless steel, both known for their excellent resistance to corrosion, rust, and wear.
   • AISI 304 stainless steel is suitable for general indoor and outdoor applications, while AISI 316 provides enhanced resistance in marine or chemical environments where exposure to saltwater or harsh chemicals is common.

2. Butt Hinge Design:

   • A butt hinge is designed with two rectangular plates (leaves) joined by a pivot pin, allowing smooth and friction-free operation when opening and closing doors or panels.
   • The 50 mm x 76 mm size provides a larger surface area compared to smaller hinges, making it suitable for heavier doors or panels, as it can handle higher loads.

3. Corrosion Resistance:

   • The stainless steel material ensures excellent rust resistance, even in moist or harsh environments, making the hinge suitable for both indoor and outdoor use.
   • AISI 316 stainless steel is preferred in marine or coastal areas due to its superior resistance to saltwater corrosion.

4. Durability and Strength:

   • Designed for medium to heavy-duty applications, the hinge provides strong load-bearing capacity and long-lasting performance, even with frequent use.
   • The stainless steel construction ensures durability in tough conditions, resisting not only corrosion but also physical wear and tear.

5. Smooth Operation:

   • The butt hinge design allows for smooth movement with minimal friction, ensuring that doors, panels, or enclosures can open and close easily without resistance over time.
   • The robust hinge pin provides reliable support, ensuring the hinge stays aligned and functional even with repeated use.

6. Pre-Drilled Holes (Optional):

   • Many butt hinges come with pre-drilled holes for easy installation using screws or bolts. This simplifies the mounting process and ensures a secure attachment.
   • Pre-drilled holes help align the hinge correctly during installation, making the process more efficient.

7. Compact but Sturdy Size:

   • The 50 mm x 76 mm size offers a good balance between compactness and strength, making it ideal for doors, panels, and enclosures where additional load-bearing is needed without taking up too much space.
   • This size is versatile enough to be used in a wide range of medium to heavy-duty applications.

Applications:

1. Industrial Enclosures:

   • Used in electrical cabinets, control boxes, and machinery enclosures, where the hinge needs to withstand frequent opening and closing for maintenance purposes.
   • The stainless steel construction ensures that the hinge remains corrosion-free even in humid or outdoor industrial environments.

2. Marine Equipment:

   • Ideal for boat compartments, hatches, and marine storage boxes, where exposure to saltwater and moisture demands high corrosion resistance.
   • AISI 316 stainless steel is the best choice for marine environments due to its superior performance in saltwater conditions.

3. Outdoor Enclosures and Cabinets:

   • Suitable for use in telecommunication boxes, utility cabinets, and outdoor storage units, where weather resistance is critical.
   • The larger size and strength of the hinge allow for use on heavier doors or panels, ensuring long-term durability.

4. Doors and Gates:

   • Used in residential or commercial doors, gates, and panels where the hinge needs to provide smooth operation and withstand heavy use.
   • The 50 x 76 mm size offers additional support compared to smaller hinges, making it suitable for heavier doors or gates.

5. Furniture and Storage Units:

   • Suitable for metal cabinets, industrial furniture, or tool storage units, especially where durability and strength are key.
   • The stainless steel construction gives it a sleek, modern appearance while offering excellent corrosion resistance.

6. Medical and Laboratory Equipment:

   • Ideal for medical cabinets, laboratory enclosures, and cleanroom doors, where hygiene and corrosion resistance are critical.
   • Stainless steel is easy to clean and maintain, ensuring sterility and long-lasting performance.

Advantages:

• Corrosion Resistance: Stainless steel construction offers long-lasting resistance to rust, making the hinge ideal for outdoor, marine, or industrial environments.
• Smooth Movement: The butt hinge design ensures smooth opening and closing, reducing wear and friction for longer-lasting operation.
• Durable and Strong: The 50x76 mm size provides a sturdy, reliable solution for heavier doors or panels that require frequent use, while still being compact enough for a wide range of applications.
• Easy Installation: Pre-drilled holes allow for quick and easy installation, providing a secure and precise fit in doors, cabinets, or enclosures.
• Versatile: The hinge’s size and strength make it suitable for a wide range of medium to heavy-duty applications, from industrial to marine and outdoor environments.

Conclusion:

A 50 x 76 mm stainless steel butt hinge is a reliable and durable solution for a wide range of medium to heavy-duty applications, offering strength, smooth operation, and corrosion resistance. It is ideal for use in industrial enclosures, marine equipment, outdoor cabinets, doors, and furniture. The stainless steel construction ensures long-term performance, even in harsh environments, while the pre-drilled holes (if included) make installation easy and secure. The larger size of the hinge compared to standard butt hinges provides additional support, making it perfect for heavier doors and high-traffic areas.
