Simpson Strong-Tie Introduces Angle Bracket for Attaching Cross- Laminated Timber to Concrete Slab in Mass Timber Applications

Simpson Strong-Tie, the leader in engineered structural connectors and building solutions, has introduced the E20/3 angle bracket as a versatile, off-the-shelf, pre-engineered and tested option for base-of-wall connections in mass timber applications where a gap is desired between the wall and slab to accommodate a sill plate or grout pad.

First introduced in the 1990s, cross-laminated timber (CLT) and other mass timber products provide the enhanced rigidity necessary for creating larger and taller wood-framed buildings. Recognized as a green building product for its ability to sequester carbon, mass timber is proliferating as specifiers seek sustainable structural building materials and builders embrace the efficiency and reduced waste of factory-based construction solutions.

The new E20/3 angle bracket is designed for efficiency and versatility and eliminates the need for custom fabrication of steel connectors on the jobsite. With an extended vertical leg, the E20/3 angle bracket is load rated for in-plane, out-of-plane, and uplift loads in designs with gaps up to 2″ between the wall and the slab. The bracket can be quickly installed in lower-capacity applications with only three SDHR screws or in higher-capacity applications with up to 18 SD screws or nails. The bracket connects to concrete slabs with 3/8″ Titen HD® anchors. (Anchors and fasteners are sold separately.)

“Simpson Strong-Tie is excited to offer a full range of tested, engineered structural connectors and building solutions for mass timber projects,” says Randy Daudet, director of Global Offsite Construction at Simpson Strong-Tie. “The E20/3 angle bracket provides a versatile, off-the- shelf solution to help maximize efficiencies and cut construction schedules, allowing contractors to take on more projects even when they’re operating with a reduced labor force.”

Backed by a robust inventory and distribution system, along with first-rate service, support, and training, the E20/3 angle bracket will allow for design flexibility while enabling mass timber projects to be built stronger, faster, and more easily than ever.
