CS16 coiled straps. I can’t tell you how many thousands (maybe more) I specified during my time as a consulting engineer. Straps are used everywhere. They were then, and are now, a go-to solution for drag and uplift loads. I didn’t have to look them up in the catalog — I knew the allowable loads by heart.
Then one day at a jobsite, I saw a contractor installing them and thought, “Wow, that is labor intensive. His arm must be so tired!” Suddenly, I felt a little guilty for all of the straps I had personally specified on my projects. I thought there must be a better way. Fast-forward 10 years, and today I’m an R&D engineer for Simpson Strong-Tie, an industry leader that prides itself on offering products that improve construction, keep costs down and allow for a safer built environment. As fate would have it, straps fall into my area of responsibility. Now, thinking about what could be done to improve a flat, steel strap is part of my job. Specifiers use straps load rated based on a National Design Specification® (NDS®) nail calculation and an American Iron and Steel Institute (AISI) steel calculation. How could Simpson Strong-Tie make that better?
