Metal floor joists vs wood. Open web trusses with wood webbing held together with metal plates. A truss, on the other hand, is made up of two or more triangles and provides structural support to roof rafters.

Steel is one of the most recycled materials in the world, it doesn’t consume trees, and has a 90% lower output to landfills than wood. Steel floor joists are not as susceptible to such expansion and contraction, which means the steel will be far less susceptible to cracking, warping, or other damage that can happen to wood. They don't warp, twist, bow, split or have knots.

I've been involved with numerious jobs in the past using a bar joist floor with concrete deck. Since 2003, we’ve been developing light gauge steel framing solutions for projects of all sizes and specifications. ¾” plywood deck for the wood option, with ¾” gypcrete at the upper floors;

The architect shows to be a composite floor using steel beams. Easier than staining and the resulting finish will pair with the lighter floors. Pound for pound, steel is so much stronger than wood.

Nails and screws will be less likely to be jostled out of place as a result of the lowered risk of expansion and contraction as well, meaning a higher level of structural stability is possible. Finally, although the product does have a convenient open web design, it is still generally higher. Bridging spans the joist bay by connecting the top of the width of one joist to the bottom of the width of the adjacent joist.
