What is a Heavy Duty Gate Hinge

A heavy-duty gate hinge is a specially engineered hinge designed to support and operate large, heavy, or high-use gates. These hinges are built for strength, durability, and long-term performance in demanding environments such as commercial facilities, industrial zones, and outdoor applications.

Why Choose an Adjustable Heavy-Duty Gate Hinge

An adjustable heavy-duty gate hinge offers the perfect blend of strength, durability, and precision control—making it ideal for both commercial and residential gate systems. Here's why it's a smart choice:

  • ANSI/BHMA A156.17: Tested the one million cycles. Our self-closing gate hinges can handle frequent use in residential & commercial spaces.
  • Spring Loaded Self Closing: Ensures automatic closing for enhanced security and convenience.
    Adjustable Speed Control: Allows users to customize the closing force and prevent slamming, even in high-wind conditions.
  • Weatherproof & Corrosion-Resistant: 316 Stainless Steel design withstands harsh weather, rust, and corrosive environments.
  • Heavyweight Bearing & Heavy-Duty: Can handle from 260–440 lbs door and even more with special door cases. Ensuring long-term reliability.
  • Long-Lasting Performance: Investment-cast stainless steel ensures maximum durability and minimal maintenance, withstanding years of heavy-duty use.
