First, wane occurs often when lumber is manufactured and cut close to the outside of the timber, resulting in missing material or a bark area. This is done to increase the yield of the timber, which increases lumber manufacturer profits but creates some issues for lumber users. Prime grades...

As teased in last month’s article, “F1 Pit Stop Each Truss,” the Enventek Collated Plate Dispenser was unveiled at BCMC 2024 Milwaukee. To many truss fabricators, it was an “A-Ha moment” to see a machine in action that solved a truss fabrication bottleneck that many...

Performing an F1 pit stop for each truss is how to Feed the Beast! Truss builders know that assembling each truss on the truss tables is just like what an F1 pit stop crew does. Both F1 pit stop crews and truss assembly crews strive for efficiency, quality, safety, and teamwork, with a shared...

Our robust Roller Plant streamlines the assembly of roof trusses – combining technology, precision, and efficiency to produce high quality trusses! Suitable for any roof truss factory, our Roller Plant is powerful, fast, accurate, and simple to operate with production numbers that will...

In a recent discussion with several very well-informed industry folks, it became clear to us that interpretation of member-to-member gaps may not be clear. In particular, we need to take a closer look at Chapter 3 Quality Criteria for the Manufacture of Metal-Plate-Connected Wood Trusses of...

Oftentimes, MiTek engineers are asked what plate embedment tolerance is allowed for metal connector plates in wood trusses. Chapter 3 of the ANSI/TPI 1 (National Design Standard for Metal Plate Connected Wood Truss Construction) addresses the tolerance for metal connector plate tooth...

If you’re in the business of roof truss manufacturing and you’re looking at ways to increase your market share, it’s time to consider adding floor truss manufacturing to your operation. Recent research shows that the global floor truss market is anticipated to rise at a...

The photo shows a 2 x 4 truss with an ANSI/TPI 1 non-compliance issue. This is something that never should have happened! Can you spot the problem? [For photo, See PDF or View in Full Issue.] If you shouted, “a missing connector,” then give yourself a gold star! As I was ranking...

Everyone who uses lumber in trusses understands that defects in lumber can impact truss performance in different ways. Some defects are not important but others will affect truss performance and can even cause truss failure. [For all photos, See PDF or View in Full Issue.] In the first photo,...

Originally intended as an improvement in lumber manufacturing, most dimensional lumber used for framing has a radius corner created during the planing process. The rounded corner radius is intended to make the lumber easier to handle and can improve the lumber’s performance because sharp...
