What Keymark Corporation does

Keymark Corporation is a privately held, family-controlled aluminum extrusion manufacturer headquartered in Fonda, NY, with a second production facility in Lakeland, FL. Founded in 1964 and now in its third generation of Keller family ownership, the company operates 700+ employees across 566,000 square feet of production space and 8 extrusion presses capable of producing custom and stock profiles up to 14 inches in circle size from 6000 series alloys. It is one of the largest vertically integrated independent extruders in the United States, controlling billet production through an on-site cast house (80%+ of weekly production from internal billet, with 38%+ recycled content) and offering in-house die design, extrusion, finishing, and packaging under one roof.

The company's product portfolio centers on aluminum extrusions complemented by AAMA-certified powder paint (2603/2604/2605), wet paint (50%/70% PVDF), anodizing (AAMA 611 Class I/II via a custom Walgren 2-step automated line handling lengths up to 32 feet), and thermal enhancement services — the patented Azon Azo-Brader Fill and Debridge process (U.S. Patent 5,577,951) and Thermal Strut polyamide bonding. Keymark is one of only four North American extruders in PPG's Certified Applicator Program, with additional approved-applicator status from Akzo Nobel, Sherwin Williams, and Axalta-Dura Coat. Its primary end-market is Building & Construction — curtain wall, commercial windows, and storefront — with tier-one project references including the World Trade Center, Capital One Headquarters, Penn Medicine Pavilion, Nashville Airport, CODA Tech Square, and the Oculus Skylight; secondary verticals span automotive, consumer durables, distribution, electrical, machinery and equipment, and transportation.

Commercially, Keymark runs a direct sales model with a national network of outside sales representatives covering all US regions, supported by dedicated air-ride trailer delivery fleets and separate NY and FL e-commerce portals. Revenue is generated through project-based custom extrusion contracts plus finishing add-ons and custom packaging services. The company has maintained a continuous capital reinvestment cadence through 2024, including a $10M+ fourth press in Florida, a 76,000 sq ft Florida facility expansion with chrome-free vertical powder coat line, and a 2025 supply agreement with Alcoa for low-carbon EcoLum billet to address embodied-carbon building codes. Ownership remains entirely with the Keller family — William L. Keller III as President and James Keller as Executive Vice President — with no disclosed institutional or private equity ownership.

Revenue model

1. Custom Aluminum Extrusion Manufacturing: Keymark manufactures custom and stock aluminum extrusion profiles. Revenue is generated through the production and sale of aluminum extrusions with various finishes. The company controls billet cost and quality through on-site casting facilities, allowing cost control and environmental sustainability through aluminum recycling.
2. Aluminum Extrusion Finishing Services: Additional revenue streams include finishing services such as powder painting, wet painting, anodizing, and thermal enhancements (fill and debridge, thermal strut). These services are applied to extrusions produced and potentially to customer-provided materials.
3. Custom Packaging: Keymark offers custom packaging services with various packaging styles including master bundle, bare sub-bundle, sub-carton, spiral sub-bundle, and paper wrapped sub-bundles to meet customer requirements.

Products and services

• Aluminum Extrusions Custom and standard aluminum extrusion profiles manufactured from 6000 series alloys (6063, 6005A, 6061, 6060) using 8 extrusion presses across the Fonda, NY and Lakeland, FL facilities, capable of producing shapes up to 14 inches in circle size for building & construction, automotive, consumer durables, distribution, electrical, machinery & equipment, and transportation customers.
• Powder Paint Thermosetting powder paint coating applied electrostatically and cured in high-temperature ovens, available in AAMA 2603, 2604, and 2605 performance standards with chrome or chrome-free pretreatment and a 10-year factory warranty on AAMA 2603 powders, applied to Keymark extrusions and customer-supplied parts.
• Wet Paint Liquid paint coating applied via electro-static discs on automated vertical paint systems, available in 70% PVDF (AAMA 2605-20), 50% PVDF (AAMA 2604-20), and baked enamels (AAMA 2603-20), with VOC abatement via thermal oxidizers at 96% destruction efficiency.
• Anodizing Electrolytic oxidation process producing protective oxide coatings in Type I (chromic acid), Type II (clear sulfuric acid), and Type III (hardcoat) classifications, with Class I and Class II performance levels per AAMA 611 specifications, executed on Keymark's custom Walgren 2-step automated anodizing line in Fonda, NY capable of anodizing and custom-coloring extrusions up to 32 feet in length.
• Fill and Debridge (Azon Thermal Barrier) Patented Azon Azo-Brader process that pours two-component polyurethane polymer into thermal barrier channels and removes the metal bridge to create structural thermal breaks, delivering mechanically locked polymer adhesion even on mill finish, gloss enhanced, and all-color anodized aluminum, with a 10-year warranty against dry-shrinkage and polymer failure.
• Thermal Strut Mechanical bond system using polyamide (I-Strut) strips from European thermal strut equipment between aluminum frame extrusions, producing a thermal break with identical coefficients of expansion to the aluminum frame for superior thermal-cycle resistance and enabling two-tone finishing (for example, high-performance paint or anodizing on the exterior with a different finish on the interior).
• Custom Packaging Multiple packaging styles including stretch-wrapped master bundles (1,000 lb), bare sub-bundles, sub-cartons, spiral sub-bundles, paper wrapped sub-bundles, and bare master bundles, designed to eliminate banding dents and reduce shipping damage.
• Quality Delivery (Dedicated Fleet) Delivery service using a dedicated fleet of trucks equipped with new aluminum flat-bed air-ride suspension trailers ensuring on-time and undamaged arrival of aluminum extrusion components to customers throughout the United States.
• Engineering and Die Manufacturing In-house engineering with CAD/CAM systems for custom die design and die manufacturing, providing precise tolerances and snap/slide fit analysis before extrusion manufacturing begins for customer-supplied or original profile designs.
• Standard Aluminum Extrusion Dies Catalog of standard aluminum extrusion dies including tubing and pipe (rectangular, round, square), rods, bars, channels, I-beams, and angles available for building and construction industry applications without the cost of a custom die.
