Rust resistance is a key factor to consider, particularly for outdoor or humid environments. Handrail brackets that are not easy to rust are essential for maintaining the structural integrity and aesthetic appeal of the staircase. Stainless steel handrail brackets are highly resistant to rust and corrosion, making them an excellent choice for outdoor staircases or areas with high moisture levels. Additionally, powder-coated or galvanized handrail brackets offer enhanced protection against rust, ensuring long-term durability and performance.
