Wall Panels

Our wall panels are custom-designed in our office using Simpson Strong-Tie’s design software. No job is too large or small to be panelized. We build panels for everything from small single family homes to large multi-story commercial projects. Our motto is, “If it can be framed in the field it can be designed and panelized in the shop!” Wall panels are a great way to frame any project but are especially useful when a framer is working with tight framing schedules or job sites with limited space for staging lumber.

Open Joist for Commercial Construction

The Open Joist 2000 wood truss has been evaluated for equivalent fire-resistant construction to dimensional lumber of 2-inch by 10-inch nominal dimension in accordance with Exception 4 of Section R302.13 of the 2015 International Residential Code (Section R501.3 of the 2012 International Residential Code) in compliance with the following code editions:

  • 2015 and 2012 International Residential Code (IRC)

Cussewago Truss is promoting Open Joist 2000 in 16″, 18″, and 20″ depths for commercial projects. Open Joist 2000 works well in residential construction as well but these depths were designed to target commercial construction.

Below is a list of qualities that make Open Joist superior to other products on the market.

  • OPEN WEB with larger clearances for HVAC, plumbing and electrical systems
  • GUARANTEED to perform for the lifetime of the structure. Ensured by testing every truss prior to shipment.
  • TRIM-ABLE at the jobsite so there’s always a perfect fit. Stock lengths ship immediately so job dimension changes don’t mean wasted costs.
  • LONGER SPANS than those possible with other engineered joists
  • DURABILITY superior to other trusses. Finger jointed connections are stronger and more resilient. Trusses strength does not degrade over time.
  • LIGHTER WEIGHT than plated versions by 20%. Less wood fiber is required (15% less) and there are no plates to add weight or cut framers’ hands.
  • ENVIRONMENT-FRIENDLY since raw materials are sustainable. Evaluated to 2012 and 2008 ICC 700 National Green Building Standard and 2013 California Green Building Standards Code
  • LOWER COST because wood fiber is minimized, truss plates are eliminated, and assembly is faster and more efficient.

TriForce Open Joist for Residential Construction

The TriForce Open Joist wood truss has been evaluated for equivalent fire-resistant construction to dimensional lumber of 2″ by 10″ nominal dimension in accordance with Exception 4 of Section R302.13 of the 2015 International Residential Code (Section R501.3 of the 2012 International Residential Code) in compliance with the following code editions:

  • 2015 and 2012 International Residential Code (IRC)

Cussewago Truss is promoting TriForce Open Joist in 11-7/8″ and 14″ depths for residential construction projects. This product also fits with some commercial projects but does not have as much design flexibility as Open Joist 2000 as in center chase, cord upgrades on shorter lengths or built to length.

Below is a list of qualities that give TriForce advantages over other products on the market.

  • CODE COMPLIANCE for first floor use without any additional protection for fire performance. This reduces cost and construction time.
  • OPEN WEB with larger clearances for HVAC, plumbing and electrical systems
  • LONGER SPANS than those possible with other engineered joists or dimensional lumber
  • TRIM-ABLE at the jobsite so there’s always a perfect fit. Stock lengths ship immediately so job dimension changes don’t mean wasted costs.
  • STOCK ITEM means no down time waiting for material to ship.

Ultralam LVL

Cussewago Truss is a wholesale provider of Ultralam LVL. This product is an excellent alternative to traditional sawn lumber when used as floor beams, door, window and garage door headers, and ridge and hip beams. A high strength-to-weight ratio makes Ultralam LVL more than 50% stronger than solid sawn wood. Ultralam LVL is evenly coated on all sides with a modified acrylic emulsion film, helping to reduce the moisture absorption rate during the construction process. With resistance to shrinking, warping, splitting and checking, Ultralam LVL is an advanced alternative to conventional lumber.

Perma-Straight I-Joists

Perma-Straight I’s won’t warp, twist or shrink, and offer more uniform dimensions than sawn lumber joists. These are the choice of designers, builders, and framers.
