New Materials Require New Hardware — Three Fasteners Engineered Specifically for Mass Timber Construction

Simpson Strong-Tie has always been a leader in designing innovative products for various construction markets. As an R&D engineer, I enjoy the opportunities for continuous exploring, experimenting and learning that come with my role. There’s never a dull moment working in research and development! At present, I’m thrilled to be part of a team that works on developing products for construction using cross-laminated-timber (CLT) and other forms of mass timber. So I have the honor of introducing three amazing fastener products that are load rated for use in CLT, wood, glulam and structural composite lumber (SCL) products (e.g., LVL, PSL, LSL).

Best Practices: The Art of the RFI

Nothing will ruin your day faster than getting a call from a builder reporting an issue with trusses you’ve designed.  You hear their frustration as they are faced with a potential delay and additional work to implement a fix.  We all desire to eliminate those calls from our daily business, and one way to do so is to work only on jobs with a perfect set of drawings.  You know, the drawings with dimensions that are 100% correct, have no errors in the listed wall heights, the heel heights are clearly spelled out with the location of the HVAC equipment and lines identified, and every load path is well thought out.

The truth, though, is that there’s really no such thing as a perfect set of drawings, because there will always be some area needing further clarification to ensure the trusses you design won’t have issues.  Although this reality is typically viewed as a source of frustration, it can be an opportunity to provide extra value to your customers by helping them resolve issues before they become a problem in the field.  To do this requires a trained eye to identify issues and the use of an RFI (Request for Information) to work through these issues with the appropriate parties involved.  In this article, we will walk through some best practices of using an RFI to help eliminate those calls.

Epoxy vs. Acrylic Adhesive Systems: Which Is Right for Me?

Not all anchoring adhesives are created equal. There are important differences between acrylic-based and epoxy-based adhesive systems — differences that affect installation, gel and cure times, and anchoring performance. In the following post, Marlou Rodriguez, S.E., of Simpson Strong-Tie, lays out some of the comparative installation advantages of each system.

There are two common types of adhesives for anchoring threaded rod or rebar into concrete — epoxy-based systems and acrylic-based systems. What’s the difference? When should you specify one rather than the other? This blog post will help you understand the differences and guide you in choosing the best adhesive for your anchoring solution.
