Material: Door hinges are typically made from durable materials like steel, stainless steel, brass, or zinc alloy. These materials are chosen for their strength and resistance to wear and corrosion.

Size: Door hinges come in various sizes to accommodate different door widths and weights. Sizes include 3-inch, 4-inch

Load Capacity: Hinges are designed to bear specific weight loads, ensuring they can support the door's weight without sagging or causing damage. Load capacity varies depending on the hinge's size and design.

Types: There are several types of door hinges, including butt hinges, continuous hinges (piano hinges), pivot hinges, and European hinges, each suited to specific applications and door styles.

Finishes: Door hinges are available in a range of finishes, such as polished brass, satin nickel, oil-rubbed bronze, and matte black. These finishes enhance both the aesthetics and corrosion resistance of the hinge.
