Long-Span Applications and Advantages

  • Trusses are lifted in rigid modules with the sheathing permanently attached; no steel workers or special installation crews are needed
  • Perfect for uncluttered, open spaces without intermediate bearing walls, columns, or obstructions such as gymnasiums, auditoriums, shopping centers and warehouses
  • Easier and less expensive to remodel, install equipment and efficiently use the space - even if it's divided into smaller areas

applications

RedBuilt™ engineered wood Red-I™ I-joists, Open-Web trusses, RedLam™ LVL and connectors are suitable for a wide variety of commercial and industrial applications where design efficiency, installed cost, labor savings and aesthetics are primary considerations. Over the last five decades, RedBuilt™ has become the first choice of architects, engineers, contractors and building owners on a diverse array of projects including:

  • Office buildings
  • Schools and universities
  • Strip malls
  • National chain store locations
  • Hotels and motels
  • Multifamily housing
  • Manufacturing facilities
  • Heavy industry sites
  • Large storage facilities

For specific information on these commercial building applications, please click on the links to the left.

RedBuilt™ offers a variety of solutions for small to large retail buildings as well as strip centers. An open floor plan is often the primary requirement as it allows the owner/developer the flexibility to create a market specific and relevant lease space.

Whether it’s our Open-Web Trusses or Red-I™ I-joists, RedBuilt can provide design assistance and system cost analysis during the concept phase of the project helping the client on the front end so there are no surprises on the back-end.

At the heart of RedBuilt’s resume is how we’ve contributed to thousands of successfully designed office spaces. RedBuilt’s experienced group of Technical Representatives bring a wealth of knowledge to help you work through the most difficult design requirements.

Floor performance or, how a floor feels, is often a major design consideration. With the aid of our technical team and the FloorChoice™ floor rating system RedBuilt can help you design a floor that balances the need for both economy and performance.

In addition to floor performance, our team can provide guidance related to how other trades interface with our products, specifically, plumbing, HVAC and fire & sound.

From long span gymnasium roofs to carefully designed classroom floors, RedBuilt’s Red-I™ Joists, RedLam™ LVL and our lineup of Open-Web Trusses provide ample solutions for this building category.

Our experience with school work goes back to the 1960s. Needless to say, we understand the processes involved and the level of detail required to make these projects a success.

Our Red-H™ open-web truss can span up to 120’ and has been used to cover many school gymnasiums. In contrast, our Red-I65™ joist is used on many shorter span applications where economy is desired.

If you need design assistance on commonly used RedBuilt products, please give your local rep a call. They will help you through the design process.

Apartments, Condos, Assisted Living Facilities, Hotels and Motels all share the same design challenges; certified fire & sound ratings, economics and post-sale logistics. Owner/Developers are looking for companies like RedBuilt™ that can provide an economical floor or roof joist and provide the shop drawing and package/delivery logistics required to keep the project coming in on time.

Likewise, general & framing contractors need to partner with companies like RedBuilt™ that understand their specific logistical needs so they too can perform on time and under budget. RedBuilt™ will help work through all the common “gotchas” on Multi-Family projects like plumbing drops, duct penetrations & sheathing layout. Our experienced team can help you save money.

Efficiency is the name of the game when it comes to designing roofs and mezzanines in the warehouse category.

The primary challenges with this building type are efficiently supporting the vertical loads and reconciling all the seismic forces. Because there are very few interior walls, the seismic forces are resolved at the outside walls.

RedBuilt™ offers efficient designs with its Red-I™ I-joists and double chord Open-Web trusses. Give your local RedBuilt representative a call for design assistance.

common questions

q1 What happens if I see a bent web after the trusses are installed?

Fork lift (fork tines) damage is the most common reason for bent webs at the job site. If you come across a bent, please give your local rep a call and they can provide guidance on what steps to take. Typically, if the web looks like the one in the photo, it is an easy repair.

q2 How do I develop the most cost effective solution when using open-web trusses?

The open-web truss load tables show the maximum load-carrying capacity of a given truss, but not necessarily the most cost‑effective truss type or depth for the application. You can also use the Specifying Economical Trussessection on page 5 of the Open Web guide or you can contact your local RedBuilt™ representative at 1‑866‑859‑6757 for assistance in finding the most economical solution for your application.

q3 Can RedBuilt™ open-web trusses be used as drag struts?

Yes. RedBuilt™ can design the chords of open-web trusses for specific axial loads. These loads must be provided by the design professional.

q4 Are your open-web trusses covered by a warranty?

Yes. RedBuilt™ warrants that its products will be free from manufacturing errors or defects in workmanship and material. In addition, provided that the product is correctly installed and used, the company warrants the adequacy of its design for the normal and expected life of the building. A copy of this warranty can be found here.

q5 What type of certification and quality assurance do open‑web trusses have?

RedBuilt™ open-web trusses are manufactured in accordance with rigorous standards, and they are monitored by a third‑party quality control agency (PFS Corporation). These standards are modeled after ISO 9000.

q6 Does RedBuilt™ provide any sprinkler system or fire-rated assembly details?

Yes. RedBuilt™ provides a number of sprinkler system suspension and fire assembly details in AutoCAD® format, which can be downloaded in the resources section.

q7 Can I modify or repair RedBuilt™ open-web trusses?

On rare occasions, repairs or modifications can be made to RedBuilt™ open‑web products—but only if the materials and instructions are provided by RedBuilt™. Contact your local RedBuilt™ representative for more information or call 1‑866‑859‑6757.

q8 Can I treat open-web products with fire-retardant or preservative?

RedBuilt™ does not recommend or warrant the use of field‑applied treatments. The use of these products may reduce the design load-carrying capacity of the members. Instead, RedBuilt™ requires that dry-use conditions be maintained.

q9 Why are some RedBuilt™ open-web trusses painted red on one end?

Many truss applications require the use of non-symmetrical trusses. Typically this is due to non-uniform design loading patterns. Non-symmetrical trusses are marked with red paint on one end, and the layout drawings provided by RedBuilt™ will specify where the red end is to be installed.

q10 Do RedBuilt™ Open-Web trusses meet the requirements set forth in the U.S. Green Building Council’s (USGBC®) Leadership in Energy and Environmental Design (LEED®) standard? 

LEED® – NC (new construction) is a commonly used building rating system designed to accelerate the development of green building practice. While products such as RedBuilt™ Open-Web trusses are not LEED® certified on an individual basis, they may contribute to point totals for a “whole building” certification. For example, the following items may be viewed as contributors toward points in the LEED® rating system:

  • RedBuilt™ offers FSC® credits for our Open-Web truss products as well as other products we manufacture or distribute. Consult your local RedBuilt™ technical representative for availability.
  • The Low Emitting Materials section (EQ 4.4) recognizes composite wood that is free from urea-formaldehyde resins. RedBuilt™ does not use ureaformaldehyde resins in any of its engineered lumber products. Material Safety Data Sheets (MSDS) are available here.
  • RedBuilt™ products may qualify for Regional Materials (MR 5.1 & 5.2) for projects located within a 500 mile radius of Portland, OR.
  • The tubular steel webs and bearing clips used in RedBuilt™ Open-Web trusses may qualify for Recycled Content (RC 4.1 & 4.2). For more information consult your RedBuilt™ technical representative.
