Customer Reviews

Size C Stair Galvanized Steel Stringer Kit is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Great Purchase1 The stringers are well engineered and very durable. The galvanized steel won't rust and the slots for the treads allow breathing room to reduce the risk of rot. The stairs are a huge improvement over previous wooden stringers. One challenge to the installation were the short mortar nails. They just did not hold. We ended up using longer concrete screws, which are very secure. However the larger screws meant that we had to use a drill larger holes--and its challenge to get through galvanized steel. Once we had the right drill bit and refreshed our patience, all worked well. All in all we are very pleased with this purchase, These stringers are build to last!
