SKYSEN, a professional manufacturer of fence gate hardware, launches the Chain Link Self-Closing Hinges. Made from carbon steel and SS304 stainless steel, they offer the dual advantages of automatic closing and secure connection. A built-in spring automatically closes the door within 3 seconds when opened 90° or more, making it compatible with both wood and vinyl fence gates. The toothed engagement structure and U-bolt hardware ensure a lateral load capacity of up to 200kg and an installation tolerance of ≤2mm. The galvanized and passivated surface has been salt spray tested for over 1,000 hours, ensuring corrosion and wear resistance. From residential courtyards to farms and horse ranches, these hinges meet the needs of efficient and secure fence gate operation and maintenance in all scenarios.

• 
  Anchored

  The bolts and nuts are of high quality, ensuring secure attachment to the fence post without breaking or moving under load. The interior has been optimized with more friction. The fastener's thread has been deepened during production to prevent loss during use, ensuring smooth operation.

• 
  Reliable Weight Support

  We offer a variety of sizes to accommodate fence gates of different weights and thicknesses. Each one is designed to provide reliable horizontal and longitudinal support for its corresponding gate, thanks to its durable material that will not wear out, break, or deform over time.

• 
  Wear-resistant

  The material is highly wear-resistant, particularly the inner part that comes into contact with the fence. This reduces friction and wear during daily operations. The fasteners are durable and maintain excellent support, ensuring a long life.

• 
  User-friendly

  The built-in spring allows for effortless gate closure, increasing efficiency and reducing safety hazards in commercial and public areas. Routine maintenance is not very demanding.

• 
  Minimalist design

  The style is simple, without any unnecessary or redundant parts, and highly practical. Its basic color scheme and smooth lines allow it to match a variety of fence styles and designs without obstructing the impression.

• 
  Risk-free

  It securely connects the fence and can withstand external damage. In commercial or important settings, a self-closing hinge can ensure personal and property security within a certain range, reducing errors and security loopholes.

1. Superior Corrosion Resistance: SS304 stainless steel has passed a 1000-hour salt spray test, with a corrosion rate of ≤0.002mm/year, a 40% improvement in corrosion resistance compared to ordinary galvanized parts. Its outdoor lifespan exceeds 15 years, making it suitable for high-corrosion areas such as coastal and industrial areas.
2. Strong Load-Bearing Stability: Horizontal load capacity of 200kg, longitudinal tensile strength ≥500N, and a toothed structure ensures a hinge-to-post clearance of ≤0.1mm and opening and closing swing of <2mm, ensuring long-term use without loosening or deformation.
3. Efficient Automatic Closing: With a spring force of 12N/mm, the door automatically closes when opened ≥90°, with a closing time of <3 seconds. This improves efficiency by 60% compared to traditional hinges, reducing manual closing costs.

The hinge core is made of carbon steel and SS304 stainless steel:
The carbon steel is hot-dip galvanized with a zinc layer ≥85μm thick, providing both physical and electrochemical protection. It boasts a tensile strength ≥500MPa and is cost-effective, making it suitable for low- to medium-corrosion environments (such as inland farms and residential areas).
SS304 stainless steel contains 18% Cr and 8% Ni, offering resistance to chloride ion corrosion (such as in swimming pools). It has a tensile strength ≥520MPa and a surface passivation treatment that forms a dense oxide film, making it suitable for coastal and high-humidity areas.
The accessory U-bolt is forged from the same material, with a thread accuracy of 6g. The internal spring is 65Mn steel, hardened and tempered to 42-48HRC, ensuring long-lasting spring force.

SKYSEN is a 15-year veteran in China, manufacturing fence and gate hardware, serving customers in over 100 countries worldwide.
Quality Assurance: ISO9001 certified, with a 7-step quality inspection process and a defect rate of less than 0.3%.
After-Sales Service: 5-year warranty (free replacement for non-intentional damage), 24-hour technical support.
