Flexible Covers for Seismic Isolators

Flexible fire-protection covers are used as passive fire barriers for seismic isolators and sliders. They are designed to withstand high temperatures and prevent fire from spreading. Because they are flexible, they adapt to different shapes and sizes, ensuring full and effective coverage. This protection is especially important in seismic regions, where isolators and sliders help reduce earthquake forces. By combining fire resistance with the ability to accommodate seismic movement, these covers provide an added layer of safety and help protect the building’s structural integrity and occupants.

Mechanical Rebar Splices

TYPE 2 SPLICES

According to ACI 318, Type 2 mechanical splices are engineered to develop at least 125% of the reinforcing bar’s specified yield strength, making them the highest-performance option for structural continuity. Because they meet this enhanced strength requirement, Type 2 splices can be placed anywhere in the reinforced concrete element, including critical regions with high tensile demand or seismic loading. This makes them the preferred choice for projects that require maximum reliability, ductility, and full structural performance.

THREADED

Bars arrive pre-threaded, eliminating field preparation and ensuring fast, accurate installation. With a clean cut, upset ends, and precision machine threading, the system provides a strong, reliable connection ideal for high-performance and seismic applications.

SHEER SCREW

COLD-SWAGGED

It requires no bar-end preparation or threading. Bolts are tightened with a ratchet or impact wrench until the heads shear off, creating a positive mechanical connection. Its speed and flexibility make it ideal for field installations and rapid construction.

Offers exceptional installation versatility, requiring no bar-end preparation or threading. It can be pre-attached using a stationary press or installed directly on site with portable pressing equipment.
