q1 What happens if I see a bent web after the trusses are installed?
Fork lift damage is the most common reason for bent webs at the job site. If you come across a bent web, 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 When should I use Red-LT™ Trusses?
The need for a product with high nailing capacity has increased significantly as model building codes have become more stringent with respect to lateral design. Not only does LSL offer the strength and consistency of engineered wood, but it also resists splitting under any reasonable nailing schedule, including most straps.
q3 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 by using the Find a Rep feature on the site.
q4 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.
Machine stress rated (MSR) lumber refers to sawn lumber that is mechanically evaluated for strength and stiffness, and then visually graded. Sawn lumber that is rated as MSR is regarded as high-quality material, and MSR is the only grade of sawn lumber used by RedBuilt™ in open-web truss chord components.
q6 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.
q7 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.
q8 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.
q9 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.
q10 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.
q11 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.
q12 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.
