What Green Link Engineering does
Green Link Engineering (legal entity Green Link, Inc.) is a privately held, US-manufactured specialty building products company headquartered and operating a manufacturing facility in Kalamazoo, Michigan. The company designs and produces engineered rooftop support systems and penetration sealing solutions for commercial and industrial low-slope roofs, including the KnuckleHeads family of height-adjustable polymer supports (Lite Pipe, Heavy Pipe, Strut, Solar, Paver, Stanchion variants and Mechanical Support Kits), the MetalHead heavy-duty aluminum support system, ChemSeals penetration seals for controlled environments, and the proprietary GREEN LINK 300 polyether adhesive/sealant. Core technology rests on a molded glass-reinforced nylon resin (Nylon 66) construction with a universal base architecture, a patent-approved triangular 100 mil aluminum MetalHead design rated to 10,000 pounds of vertical compression, and a dense regulatory compliance stack covering ASTM, federal, AAMA, LEED, CARB, SCAQMD, and California Proposition 65 standards.
The company serves four primary customer segments: commercial building owners and property managers, HVAC and roofing contractors, solar energy installers, and controlled environment facilities (pharmaceutical, electronics, nano-technology, and food preparation). It makes money primarily through hardware sales of support and sealing components, with pricing handled via Request a Quote workflows rather than public list pricing.
Go-to-market is a multi-channel enterprise field sales model: an extensive independent sales representative network covers the United States (with Alaska, Arizona, and Puerto Rico served directly from the corporate office), exclusive distributor partnerships handle Canada (District Sales Company) and the Caribbean Basin, Central and Latin America (Danosa Caribbean), and digital specification channels distribute CAD/BIM content through BIMSmith, BIMobject, and ARCAT. Marketing investment is sustained across trade shows (Chicago Build 2025, AHR Expo 2026, Construct Show), a YouTube channel with installation and product videos, a blog, and active LinkedIn, Facebook, Instagram, and X presences. The company is founder-led by Phil Georgeau, with Lisa Mulder as Technical Director and Ondrej Pekarovic as Design Engineer, and shows no visible external venture capital, private equity, or parent-company ownership.

Green Link Engineering competitors and assessment
Company assessmentBroad incumbents
- Carlisle Construction Materials: Carlisle is a major commercial roofing manufacturer offering membranes, accessories, and rooftop support-related products through a deep commercial roofing contractor network. As a broad incumbent, Carlisle competes for the roofing accessory wallet share that Green Link targets through KnuckleHead and ChemSeals.
- Atkore (Unistrut): Atkore owns the Unistrut brand of metal framing and support channels used broadly in mechanical, electrical, and rooftop support applications. Unistrut competes as an alternative to Green Link's KnuckleHead Strut and MetalHead systems and benefits from massive scale, distributor reach, and brand recognition.
- Eaton (B-Line): Eaton's B-Line series includes strut, rooftop support, and cable management systems widely specified in commercial construction. Comparable as a broad incumbent with overlapping rooftop support and strut product lines serving the same mechanical and electrical contractor channels.
- Tremco Construction Products Group: Tremco manufactures roofing sealants, adhesives, and weatherproofing products for commercial construction. Comparable as a broad incumbent in the roofing sealant/adhesive category overlapping with Green Link's GREEN LINK Adhesive/Sealant offering.
Direct peers

- PHP Systems/Design: PHP Systems/Design manufactures engineered rooftop pipe and equipment support systems for commercial low-slope roofs. Closely comparable to Green Link's KnuckleHead line in product, customer (HVAC and mechanical contractors), and specification-driven sales motion.
- nVent (ERICO): nVent's ERICO brand sells the Caddy Pyramid rooftop support system, a directly comparable engineered polymer rooftop support product for pipes, conduit, cable trays, and HVAC equipment. Same customer base (commercial roofing contractors and mechanical contractors), same product category, similar channel to electrical and mechanical distributors.
- MAPA Products: MAPA Products manufactures HVAC and plumbing rooftop support systems used by mechanical contractors on commercial roofs. Comparable to Green Link's Mechanical Support Kits and KnuckleHead Strut/Pipe supports, with similar application focus on stabilizing rooftop equipment.
Emerging players
- Eberl Iron Works: Eberl Iron Works manufactures structural and miscellaneous metal products including rooftop support and equipment framing solutions. Comparable as a specialty/regional manufacturer overlapping with Green Link's MetalHead aluminum support system for heavy rooftop equipment.
- Roof Screen Systems: Roof Screen Systems designs and manufactures engineered rooftop equipment screens and support structures for HVAC and other rooftop units. Comparable as a niche emerging player in the same rooftop accessories category, particularly in the equipment screening and support segment.
