Materials & Finishes
Materials
Cold-rolled steel arms with nickel plating are standard for value, while stainless steel suits humid kitchens and bathrooms. Cup and arm gauge drive the cycle life and sag resistance.
- Stainless Steel
- Carbon Steel
- Zinc Alloy
- Aluminum
- Brass
- Copper
Finishes
Hinges are usually nickel-plated and hidden inside the cabinet, so finish is about corrosion resistance rather than appearance. Specify a heavier plating or stainless steel for high-humidity programs.
- Satin Chrome
- Zinc Plated
- Aged Brass
- Polished Chrome
- Oil Rubbed Bronze
- White
- Galvanized
- Gold
