We use curves a lot when we build our decks. Sometimes they can solve design problems, like by avoiding existing landscaping or providing extra deck space for a table and chairs. Other times, the curve is all about aesthetics. Not surprisingly, curves add significant labor and expense to a deck project. We find the process is easiest when you start with a steel deck frame. A steel frame costs 30% to 40% more than treated lumber, but the ability to quickly adapt the components to form a curve make it worth the expense. Plus, customers like the uniform dark brown of the Trex Transcend steel joists and beams that we use, and the rot and insect resistance are icing on the cake. Our crew likes how the steel components are lightweight and dead straight. Although we can usually convince clients to go with the steel track and joists once we explain the advantages.
