Sometimes it is necessary to deviate from the truss design drawing and use a different connector. This may happen when a specific size connector is not available or when the original connector has been removed. Per ANSI/TPI 1 Section 3.6.3, a metal connector can be substituted if the new...

When completing an in-house inspection, a critical plate inspection is required for each truss inspected. This requirement is from ANSI/TPI 1–2014. Specifically, per section 3.7.1: No less than one critical joint per Truss selected for inspection, on average across all operational...

Face the facts—occasionally, it is necessary to replace connectors. It’s part of the manufacturing process. In my May 2016 article, Is There a Reduction For Plating in a Previously Plated Area?, we discuss the limitations and considerations of removing a plate, including upsizing the...

On occasion, we are required to utilize a detailed tooth count to qualify a connection on a metal plate connected wood truss. Fortunately, we have several tools that can assist us. My June article, “Which is Better: Plate Placement Method or Tooth Count Method?”, includes a...

Is your operation on target when it comes to quality?  September is your chance to find out!  At BCMC Omaha last year, our Timber Products Inspection booth gave all attendees the chance to test their skills and acumen for Quality Assurance. This year at BCMC Columbus on September...

The development of the 4 x 2 floor truss system revolutionized the truss industry. Plating to the narrow edge of the chord members presented some issues, but all in all it allowed component fabricators another product offering, expanding their potential business. In the original designs, it was...

As many communities and potential homeowners struggle with housing affordability, tiny houses have emerged as part of the solution. Assuring these tiny houses deliver the same level of safety and efficiency of other permanent housing solutions is essential. Local building codes and the...

With high lumber costs and volatile pricing, it is very reasonable to look for options to normal resources. Many fabricators and lumber manufacturers have been experimenting with using non-regular channels for lumber, including some choices that have created problems and issues with their...

To answer the question of which is the better method, we should start with a little background. A critical plate is a plate with a Joint Stress Index of 80% or greater. The ANSI/TPI 1–2014 Standard stipulates that critical plate inspections must be conducted when completing the three...

Due to the nature of wood, lumber characteristics can vary in every piece. Even “in grade” lumber can have drastic variations in performance. How can we deal with and adjust for natural defects and variability? We have discussed roof trusses in previous articles, including...
