Architectural Castings

What Architectural Castings does

Architectural Castings, Inc. is a Portland, Oregon-based custom architectural fabrication company founded in 1978 that designs and produces replacement components for historic masonry restoration and contemporary construction. The company specializes in deteriorated, missing, or damaged terra cotta, cast stone, and natural stone elements on facades, cornices, balustrades, and ornamental features, serving buildings on the National Register of Historic Places as well as non-historic structures requiring high-quality architectural casting work.

The company's technical capabilities span five material systems: Glass Fiber Reinforced Concrete (GFRC), Polymer-modified Glass Fiber Reinforced Gypsum (PGRG), Fiberglass Reinforced Plastic (FRP), Glass Fiber Reinforced Gypsum (GRG), and conventional precast concrete and cast stone. Proprietary production processes yield GFRC parts at approximately 1 inch wall thickness with internal webbing capability and pozzolanic mix designs replacing 25% of cement content for enhanced freeze-thaw resistance. Fabrication combines traditional hand sculpting with laser scanning, CNC machining, and CAD/CAM design. The company provides end-to-end services including condition assessments, field dimensioning, shop drawings, mold creation, in-house production, stainless steel framing/attachment engineering, finishing, and installation assistance.

Architectural Castings operates a project-based, sales-led business model with revenue generated through design-build contracts and competitive bidding on public works projects. Projects are acquired through direct relationships with project architects, masonry restoration contractors, and building owners/developers, with pricing established per-project based on scope, materials, complexity, and volume. Customer segments include historic preservation, government, higher education, hospitality, religious, and entertainment clients across at least seven U.S. states. The company is privately held, self-funded, and operates from a single Portland production facility with 11-50 employees.

Products and services

• Glass Fiber Reinforced Concrete (GFRC) Products Custom GFRC parts for replacement of deteriorated terra cotta, cast stone, and natural stone masonry in facade and cornice renovation projects. The company's primary material system, producing thin-shelled composite components with integral or applied finishes.
• Pre-cast Concrete and Cast Stone Conventional wet-mix concrete and dry-pack cast stone products for load-bearing applications in historic restoration, ranging from conventional vibrated pours to fine aggregate tamped molds.
• Polymer-modified Glass Fiber Reinforced Gypsum (PGRG) Exterior-grade gypsum composite replacing water with acrylic polymer system (40% matrix), offering moderate weight with excellent dimensional stability for large projecting cornices without requiring sub-framing support.
• Fiberglass Reinforced Plastic (FRP) Original thin-shelled composite combining glass fiber reinforcement with polyester or epoxy resins, providing the lightest and strongest thin-shell exterior material with the greatest field history.
• Glass Fiber Reinforced Gypsum (GRG) High strength gypsum plaster with glass fiber for interior applications, producing very light but stiff elements suitable for large decorative moldings and ceiling profiles.
• Design and Engineering Services Delegated-design and fully documented construction drawing services including connection design, installation drawings, 3D detailing, and modular component design with false joints for streamlined installation, targeted at architects, contractors, and building owners.
• Onsite Services Field dimensioning, template collection, mold impressions, laser scanning of facades and individual parts, packaging, delivery, and assembly methods tailored to project requirements.
• Tooling and Mold Construction Custom tooling development for complex shapes using both traditional sculpting and CNC machining, rubber mold creation, and pattern making for cast stone and GFRC production.
• Molding and Fabrication Services In-house production using GFRC, FRP, and PGRG materials, including framing and connection systems and integrated sub-assemblies.
• Finishing Services Custom color matching, integral finishes replicating natural stone, applied coatings matching terra cotta glaze finishes, and media-blasting or etching techniques for texture reproduction.
