Sturdy. Good buy - Good buy. Heavy duty and sturdy. I looked at sets of 2. Glad I decided to buy the set of 3. I want to enclose the face of each step as well. I'm still working on that plan. I may have to drill holes to attach the vertical pieces. Maybe even glue?? Still working on that. Review: Heavy duty and easy to install. - I use these for my rentals. They are easy to install and heavy duty. They'll last far longer that the treated pine that we have always made stringers out of. Instead of using the screws provided to install treads i use 2-1/2" self drilling screws and pre drill the holes with a 1/8" bit. Using the short provided screws from the bottom is a pain ## Features - 【High Strength Galvanized Steel】- Our Stair Stringer are made of heavy-duty galvanized steel, with high density, strong load-bearing capacity, durability, wear resistance, and are very suitable for long-term outdoor use - 【4-Hole Design】- Each flat part of our Stair Stringer is equipped with 4 bolt holes for connecting wooden boards.
