Change the infill, not the system. CIRCA carries one refined aesthetic across glass, wire mesh, perforated metal, laser-cut panels, cable, picket, multiline and CableNet.
At the core of every CIRCA guard is the same engineered platform: Ø2-inch round tubular stainless-steel posts and a consistent fixed-point, framed-panel detail. That shared platform lets a project change infill floor to floor — or building to building — while the posts, hardware, finish and top rail stay identical. Posts space up to 5'-0" on center for glass and 4'-0" for cable and multiline, all engineered to the commercial 42-inch guard height at 200 lbf concentrated and 50 lbf/ft uniform loads.
Every CIRCA configuration is built for real projects: laminated glass from 1/2" to 1" with PVB or SGP interlayers, Ø3/16" Type-316 stainless cable, architectural stainless mesh, and perforated or laser-cut panels — all beneath a stainless-tube, U-cap or wood (maple, cherry or oak) top rail. Integrated iRAIL™ LED lighting, standard #6 satin and #8 mirror stainless finishes, architectural powder-coat colors, and PVDF are available across the family.
Because CIRCA is one system, its CAD details, Revit/BIM families and 3-part CSI specification (Section 05 73 00) are shared across every infill — and mounting adapts to concrete, steel and pour-stop substrates in top-of-slab, fascia and core-drilled conditions. The platform is third-party validated under ICC-ES ESR-4405 and tested to ASTM C1172 and C1048, with ETL-certified illuminated options.

SPECIFIER FAQ
CIRCA railing system — frequently asked questions
What is the CIRCA railing system?
CIRCA is VIVA Railings' post-supported guard and handrail system, built on Ø2-inch round tubular stainless-steel posts with fixed-point, framed infill panels. One engineered platform is offered in eight interchangeable infills — glass, wire mesh, perforated metal, laser-cut panels, cable, picket, multiline and CableNet — so the look can change while the system, hardware, finish and spec stay the same.
Which infill options does CIRCA offer?
Eight: laminated glass, architectural wire mesh, perforated metal, 1/4-inch laser-cut aluminum panels with 60-plus patterns, Ø3/16-inch stainless cable, Ø1/2-inch stainless picket, horizontal multiline, and flexible stainless CableNet mesh. Every infill shares the same posts, hardware, finishes and top-rail options.
Is the CIRCA railing system code-compliant?
Yes. CIRCA is engineered to the commercial 42-inch guard height with 200 lbf concentrated and 50 lbf/ft uniform loads, meets the 4-inch sphere opening rule, and is third-party validated under ICC-ES ESR-4405 and tested to ASTM C1172 and C1048. Every project ships with Professional-Engineer-stamped shop drawings and calculations sealed in the project state, and illuminated options are ETL-certified.
Can I download Revit, BIM and CAD files for CIRCA?
Yes. The Revit/BIM family (.rfa), CAD details (.dwg), 3-part CSI specification (Section 05 73 00) and product-data PDF are available directly from this page with no login required, and the downloadable set reflects your selected infill and pattern.
