floor systems-ewp
Description
TrimJoist® is a patented open-web floor truss system that combines the strength of an I-joist with the layout flexibility of a truss. Designed with wood diagonal webs and an open center, TrimJoist® allows for field trimming and easy routing of utilities—making it ideal for modern framing.
Common Applications
- •Single-family homes
- •Multi-family structures
- •Light commercial buildings
- •Remodels or additions where flexibility and utility access are key
