The structural steel I-beam is 150 years old. It works. But it is heavy, susceptible to corrosion, and acoustically poor. The RigidCore gyroid composite beam offers superior stiffness-to-weight, better seismic vibration damping, and a geometry that steel cannot replicate — manufacturable at scale.
Global construction market
Structural steel segment
Since the I-beam geometry was standardized
The structural steel I-beam has not fundamentally changed since the 1870s. Every highrise, bridge, and industrial building in the world uses a variation of the same geometry. A better beam — lighter, stiffer per pound, with better vibration damping — is a category-defining product.
Gyroid composite geometry distributes load across the entire cross-section, not just the flanges. Equal stiffness at 40–60% less mass.
Composite material and gyroid geometry absorb vibration. Critical for seismic performance, floor vibration in occupied spaces, and mechanical equipment mounting.
No rust. No galvanizing required. No scheduled recoating. Composite beam surfaces are inherently stable in moisture, salt, and chemical environments.
Steel expands and contracts with temperature. Composite beams show dramatically lower thermal expansion — critical for precision structures and long-span applications.
Structural engineering assessment for a specific construction application. We analyze span requirements, load conditions, code compliance path, and produce a preliminary specification for a RigidCore composite beam that meets or exceeds the steel alternative.
A full-scale gyroid composite beam section manufactured to engineering specification for testing and validation. Includes FEA-validated design, manufacturing documentation, and load test support. Target applications: pilot projects, university research partnerships, structural engineer validation programs.
Small production run of RigidCore composite beams for a specific construction project. Requires completed engineering specification, structural engineer of record, and building permit path. KI supplies the beam. The structural engineer of record stamps the drawings.
License the gyroid composite beam geometry and manufacturing specification to a composite fabricator or construction materials manufacturer. Licensee produces at volume. KI collects royalties. Structure through RigidRoyalty.
Primary load-bearing application. Replace steel I-beams in multi-story commercial and residential structures.
Open-plan offices, retail spaces, and warehouses where span length and floor vibration are design constraints.
Pedestrian bridges, mezzanine connections, and secondary bridge structural elements where corrosion resistance is critical.
Retrofit existing structures with lighter beams that improve seismic performance without adding foundation load.
Factory floor mezzanines, equipment platforms, and warehouse second-level structures where dead load matters.
Vibration-sensitive equipment mounting. Semiconductor, metrology, and laboratory applications where floor vibration degrades measurement.
Commercial-grade structural simulation documenting stiffness, damping, and load performance against ASTM A992 steel baseline. This is the technical foundation of the patent claims and the data a structural engineer needs to specify the beam.
Work with ICC and structural engineering organizations to establish a code compliance pathway. Novel structural materials require testing documentation and evaluation reports before building departments will accept them.
First real-world installation under the supervision of a structural engineer of record. Documents real-world performance and provides the case study that opens the broader market.
