Chi hinges are designed as heavy duty garage door hinges for long life and stable operation:
• High-strength materials – 14 gauge or 16 gauge galvanized steel, optional stainless steel for specific applications, providing strength and impact resistance for heavy residential doors.
• Corrosion-resistant finishes – hot-dip galvanizing, zinc plating or powder-coat finishes help protect hinges in coastal or high-humidity environments.
• Smooth & quiet operation – precise hinge geometry and clean burr-free edges work together with quality rollers to reduce friction and noise during daily use.
• Consistent fitment – standard hole patterns and accurate bending angles ensure interchangeability with most mainstream residential sectional garage doors and garage door hardware systems.
These advantages make our residential garage door hinges a reliable choice for both wholesalers & distributors and installers.

U.S. Residential Sectional Garage Door Hinges
• End hinges #1, #2, #3, #4, #5, #6 – installed between each section at the door edges. Each number has a specific offset to match the curve of the 2" track and keep the door running straight.
• Center hinges – flat or low-profile hinges mounted between sections at the center stiles, designed to keep the panels aligned without roller sleeves.
European Style Finger-Safe Garage Door Hinges
• Finger-safe center hinges – matched to finger protection panel profiles, helping prevent fingers from entering the joint between sections.
• Side hinges for 40–45 mm panels – designed for thicker insulated panels and multi-panel configurations commonly used in Europe.
• Different drilling patterns and hinge geometry to suit European frame and track systems.
