Stainless steel is a popular choice for heavy-duty hinges for windows due to its strength, durability, and resistance to corrosion. When looking for a stainless steel heavy-duty hinge for windows, there are several factors to consider:

Load capacity: The hinge should be able to support the weight of the window. It is important to choose a hinge with a load capacity that exceeds the weight of the window.

Size: The size of the hinge should be appropriate for the size and weight of the window. A larger hinge may be necessary for heavier windows.

Type of hinge: There are several types of hinges available, including butt hinges, continuous hinges, and pivot hinges. The type of hinge you choose will depend on the design of your window and the type of operation you require.

Finish: Stainless steel hinges come in a variety of finishes, including brushed, polished, and black oxide. Choose a finish that complements the look of your window and the surrounding hardware.

Installation: Make sure the hinge is easy to install and comes with all necessary mounting hardware.
