Hirun International

What Hirun International does

Hirun International is a Taiwan-based private engineering company that designs, produces, tests, and installs structural protection devices for bridges, buildings, hospitals, rail systems, and other infrastructure. Its portfolio covers antiseismic isolators and dampers, structural bearings, expansion joints, post-tensioning systems, and tuned-mass and vibration-control devices. Customers include government agencies, transit authorities, engineering consultants, contractors, infrastructure developers, and selected enterprises.

The technologies address load transfer, seismic isolation, energy dissipation, structural movement, and vibration control. HISLIDE/HIPEND sliding-pendulum isolators use friction and pendulum-based re-centering, HILEAD combines rubber elasticity with a lead core, and HIFLUID devices distinguish slow movement from dynamic loads. Hirun also identifies HI-3 as a proprietary high-performance sliding material. The company states that its team has more than 50 years of relevant experience, has contributed to EN 1337 and EN 15129, and holds patents covering dampers, materials, and customized device combinations.

Revenue is generated through project-based sales of engineered devices and bundled engineering services, including design, analysis, testing qualification, and installation supervision. Hirun sells directly to project owners and their engineering and construction partners; pricing is quote-based and tied to specifications, quantities, testing, and installation requirements. Its disclosed references span rail, bridge, hospital, power, and commercial-building projects across multiple countries, but no public revenue or backlog is provided.

Products and services

• HIDAMP High Damping Rubber Bearings Base isolation devices using a high-damping rubber compound for energy dissipation in low to medium seismic areas. Designed for bridges, buildings and critical structures; cost-effective solution with hard rubber compound (shear modulus G = 1.6 MPa, equivalent viscous damping ξ = 16%).
• HILEAD Lead Rubber Bearings Seismic isolators that combine rubber elasticity (re-centering) with a lead core stressed over yield limit (energy dissipation). Suitable for bridges and buildings in medium to high seismic areas, with 60+ year service life.
• HISLIDE / HIPEND Sliding Pendulum Isolators Friction-based sliding pendulum isolators combining friction energy dissipation with pendulum-based re-centering for bridges and buildings in high seismic areas. Unlimited vertical load capacity, high horizontal displacement and very high re-centering capacity, with a 100+ year service life and negligible maintenance.
• HIFLUID VDD Fluid Viscous Dampers Energy dissipation devices that allow slow movements (creep, shrinkage, temperature effects) with negligible reaction while maximising energy dissipation during dynamic motion such as earthquakes. Designed for bridges, very long-span bridges and dissipative bracing for tall buildings.
• HIFLUID LUD Lock-Up Devices Lock-up devices that permit slow structural movement (creep, shrinkage, temperature effects) while developing maximum reaction under dynamic effects such as train braking forces and earthquakes. Used for bridges, railway bridges and to share seismic loads between structural elements, including retrofit applications.
• HIFLOW Spherical Bearings Spherical bearings with a convex spherical calotte and sliding material (PTFE according to EN 1337.2 or proprietary HI-3 sliding material), accommodating high rotations of 0.05 rad or more. Suitable for any bridge type up to very large spans.
• HIPOT Pot Bearings Pot bearings combined with sliding elements for very high vertical and horizontal loads. Consist of an elastomeric pad confined in a cylinder with a close-fitting piston and internal seal.
• HIBLOC Elastomeric Bearings Elastomeric bearings reinforced internally with steel plates; an economical solution for small to medium span bridges, supporting vertical loads while permitting horizontal displacements and rotations.
• HITUNE Tuned Mass Dampers Tuned mass dampers consisting of mass, spring and damper, tuned to specific structural frequencies to reduce vibrations induced by wind, earthquakes, traffic, human behaviour or machinery.
• HIFLEX Rubber Mat Expansion Joints Rubber-steel vulcanised mat expansion joints that accommodate movements up to 400 mm in service conditions and up to 1000 mm under earthquake conditions.
• HIMOD Modular Expansion Joints Modular expansion joints composed of special steel profiles with interlocked rubber seals, used for very large movements of 2000 mm or more.
• HICOMB Finger Joints Finger joints composed of cantilever symmetrical and non-symmetrical elements that interpenetrate to bridge deck joint gaps. Designed for very large movements.
• HIPOST Post-Tensioning System Post-tensioning system using 15 mm diameter 7-wire strands for stressing concrete, steel, wood or other structures. Applied to bridges, buildings, tanks and marine structures.
