Tapered I-Joists

Single Taper / Slope · Any Series · Custom Slope

Available across all six WEB-i® series, factory-tapered I-joists eliminate the need for separate tapered blocking, sleepers, or built-up ridge assemblies on sloped roof systems. Achieve positive drainage and precise roof pitch directly from the structural member, engineered to your exact slope specification.

Single taper (one sloped cut) — factory-set slope to your exact specification
Available in all six series - any flange grade, any web thickness
Eliminates site-cut tapering labor and material waste entirely
Precise factory slope - no field layout errors or callbacks
Ideal for low-slope commercial roofs requiring positive drainage
Reduces overall roof system weight vs. blocking-based alternatives

★ Premium Option

Cambered I-Joists

Factory Camber · Dead Load Offset · Project-Specific

WebJoist manufactures I-joists with engineered camber built directly into the member at the factory, counteracting anticipated dead load deflection so floors and roofs settle to true level under service conditions. No field shimming, no callbacks, no long-term deflection complaints.

Factory camber calculated to offset specified dead load deflection
Eliminates post-installation shimming and leveling labor entirely
Ideal for long-span commercial floors with concentrated dead loads
Improves long-term performance and occupant satisfaction
Available across all six WEB-i® series on request

Factory-Installed Services

Save Time on Site.
Eliminate Waste.

Two premium factory services ordered with your I-joists and delivered ready to install. No cutting. No drilling. No callbacks. Available on any WEB-i® series.

Premium Factory Service · PET

Precision End Trim

Every I-joist cut to your exact project length at the factory with square, precision-calibrated ends. Eliminates the single most common source of on-site I-joist waste and removes a full step from the installation sequence. Delivered cut-to-length and ready to set.

Eliminates Field Cutting Zero End Waste Faster Install Cycle Square Bearing Surface

Premium Factory Service · IWS

Installed Web Stiffeners

Web stiffeners required at bearing points and concentrated load locations are factory-nailed at precise positions before delivery. One of the most time-consuming field tasks in I-joist installation, eliminated entirely. Arrive on site installed, inspected, and ready.
