Introducing The Next-Generation Strong-Drive® SDHR Combo-Head Screws: Steel-to-Wood Structural Fastening Solution with Enhanced Durability and Hydrogen Embrittlement Resistance

Now with Black E-Coat Finish — Compliant with CSA O86:24 Hydrogen Embrittlement Requirements

In response to the hydrogen embrittlement requirements defined in CSA O86:24 and the increasing structural demands of modern heavy timber and mass timber construction, Simpson Strong-Tie® has developed the next-generation Strong-Drive® SDHR Combo-Head Screw with a black e-coat finish. This updated version is designed to meet the latest durability and hardness requirements while delivering the same high-capacity structural performance that engineers have come to rely on in steel-to-wood applications. The new SDHR is listed in the ICC-ES ESR-3046 Evaluation Report.

Code Reports: Uniform Application of Code Intent in a Diverse Environment

Woodworks invited me to do a presentation on Testing and Evaluation of Products for Wood-framed Construction, and I found you can’t really talk about testing without talking about the test standards and criteria used in product evaluations. Usually the goal in testing to these standards is to show compliance with the intent of the building code and have the product listed in a code report.

Why not just follow the code?

Innovative architectural and structural building products not addressed by the building code are in every building. Revisions to the building code are considered on a three-year cycle and some standards are on a five-year cycle. Sometimes it may take several cycles to address a new building product.
