Your door handles get used on a daily basis, and even if it's for a split second, this build up to a lot of use and daily wear and tear. For the most durable front door hardware finish, think about the type of materials that fare well outside.
Chrome, nickel and stainless steel do better outside, and brass has a luxurious, golden coloring that brings elegance as well as durability to your front door. Meanwhile, stay clear of wooden knobs which might erode over time with constant use and outdoor weather conditions.
