Compare I-joist products across every major manufacturer, TJI, BCI, PWI, BLI, with span tables, load data, and depth options. No login. No catalog flipping.
TJI (Weyerhaeuser), BCI (Boise Cascade), PWI (Pacific Woodtech), BLI (Louisiana-Pacific), and more, all major manufacturers in one tool.
Yes. The standard I-Joist Compare is completely free. Pro features like multi-tab comparison and PDF/Excel export are available with a subscription.
All standard residential and commercial I-joist depths from 9-1/2" through 16", across all common series (TJI 110, 210, 230, 360, 560; BCI 5000, 6000, 6500, 90, etc.).
The tool shows allowable spans for each product based on spacing, load, and L/deflection limits. Green = passes, red = fails. Compare products at identical conditions.
