What Tensa America does

Tensa America (legal entity TENSA AMERICA LLC) is the U.S. regional subsidiary of Tensacciai S.r.l., which operates as the structural engineering division of the Italian Rizzani de Eccher Group. Headquartered in Bay Harbor Islands, Florida, the company designs and supplies post-tensioning systems, stay cables, ground anchors, structural bearings, and expansion joints for bridges, buildings, and large-scale infrastructure. Its specialized seismic protection portfolio includes base isolators, velocity-dependent dampers and shock transmitter units (STUs), displacement-dependent elasto-plastic devices (TEPD) using AISI 304 stainless steel hysteretic elements, and rigid connection devices (TSTD) using silicone-based oleodynamic cylinders.

The company sells custom-engineered structural systems to engineering contractors, project developers, and public infrastructure clients through a consultative enterprise field sales motion, supported by 'Request a solution' lead capture forms and downloadable technical brochures in English and Spanish. Its customer base is concentrated in infrastructure and construction projects requiring seismic protection, post-construction reinforcement, and rehabilitation of existing assets, with 25 years of claimed domain experience and a 2017 PTI Journal Excellence Award for a Manhattan post-tensioning project.

Tensa America operates as part of a globally distributed network that includes offices in Italy (Milan HQ, Rome, Pozzuolo del Friuli warehouse), India (Mumbai), Mexico (Mexico City), and Australia (Adelaide), all under the Rizzani de Eccher corporate umbrella. The business model is project-based and one-time in nature: revenue is generated through the sale of custom-engineered hardware into individual infrastructure projects rather than through recurring licensing or service contracts. Pricing is not publicly disclosed and varies by project specification and engineering complexity.

Core offering

Tensa America designs, manufactures and supplies structural engineering systems for infrastructure and building projects. Its portfolio includes stay cables, post-tensioning systems, ground anchors, structural bearings and expansion joints, complemented by a seismic protection family covering seismic isolators, velocity-dependent dampers and shock transmitter units (STUs), displacement-dependent elasto-plastic devices (TEPD), and rigid connection devices (TSTD).

Product overview

Tensa America is a structural engineering company specializing in post-tensioning systems and seismic protection solutions for the construction industry. The company offers a comprehensive portfolio of physical infrastructure products rather than software solutions. Their core product line includes Stay Cables, Post Tensioning Systems, Ground Anchors, Bearings, and Expansion Joints, which are complemented by a specialized Seismic Protection product family consisting of Seismic Isolators, Velocity Dependent Devices (Dampers & STUs), Displacement Dependent Devices (TENS Elasto-Plastic Device - TEPD), and Rigid Connection Devices (TENS Shock Transmitter Device - TSTD). These products form an integrated system for structural engineering applications, with the seismic devices designed to work together to provide comprehensive protection for buildings and infrastructure against earthquake forces.

Brands

• TENSA: Structural engineering and post tensioning systems including stay cables, post tensioning, ground anchors, bearings, expansion joints, and seismic devices.

Products and services

• Stay Cables Structural engineering stay cable systems for bridges and large-scale infrastructure projects, providing support and tensioning capabilities for contractors and project developers.
• Post Tensioning Systems Post-tensioning systems for slabs and structural concrete applications, enabling efficient load distribution and reduced material usage in building and infrastructure projects.
• Ground Anchors Ground anchor systems for geotechnical stabilization and structural support in construction and infrastructure applications.
• Bearings Structural bearing systems designed to support and facilitate movement in bridges and building structures, accommodating thermal expansion and seismic movement.
• Expansion Joints Expansion joint systems that accommodate structural movement caused by temperature changes, seismic activity, and other dynamic loads in infrastructure projects.
• Seismic Isolators Base isolation systems that protect constructions and human lives by reducing seismic hazard through advanced isolation technology, backed by 25 years of experience.
• Velocity Dependent Devices (Dampers & STUs) Velocity dependent devices designed to reduce seismic structural response by adding energy dissipation to the system, including Shock Transmitter Units (STUs).
• TENS Elasto-Plastic Device (TEPD) Displacement dependent steel restraint devices with elasto-plastic constitutive law that transmit horizontal forces and provide high dissipation with stable hysteretic behavior, featuring 'C' shaped hysteretic elements in AISI 304 stainless steel.
• TENS Shock Transmitter Device (TSTD) Rigid connection devices — temporary oleodynamic connection devices that become pseudo-rigid under impulsive external forces and develop negligible reaction during slowly imposed movements, consisting of steel cylinders filled with silicone-based oil.
