Green-Tek

What Green-Tek does

Green-Tek, Inc. is a privately held manufacturer, converter, fabricator, and master distributor of greenhouse coverings and components headquartered in Beloit, Wisconsin. Founded in 2000 and operating for over 25 years, the company serves commercial greenhouse growers, agricultural operations, distributors, dealers, and greenhouse manufacturers across North America through a one-stop product portfolio. The portfolio spans polycarbonate glazing systems, polyethylene films, shade and light management nets, protection screens, ventilation fans, fertilizer and chemical injectors, ground cover, and fastening systems, with the company emphasizing quick shipment, cut-to-size fabrication, no minimum order requirements, and consolidated billing on a single bill of lading.

The company's underlying technology is rooted in materials science and horticultural engineering rather than software. Notable proprietary elements include the Dynaglas Plus built-in condensate control system backed by a 10-year limited warranty, the ThermaGlas UV protection co-extrusion process, the SolarSoft light-diffusing pigmentation used in Dynaglas and ThermaGlas sheets, the ChromatiNet spectrum-management shade net technology, the patented SuperDos internal mixing chamber, and high-efficiency fan designs reaching up to 26 CFM/Watt. Products carry third-party certifications including NFPA 701, ASTM E-84, OSHA CFR 1910.23, UL 580, and UL94-5VA. Green-Tek owns a broad registered brand portfolio (Dynaglas, ThermaGlas, ChromatiNet, Aluminet, Shade-Rite, Cover-Rite, SolarSoft, Shark Bite) and has maintained a 20+ year affiliation with the Aluminet product line.

Green-Tek generates revenue primarily through one-time product sales of greenhouse components, supplemented by factory-certified parts sales and warranty/non-warranty repair services for Dosmatic and Chemilizer injectors. Pricing is quote-based and not publicly disclosed, with no minimum order quantities. The go-to-market model is channel-driven: the company partners with the leading distributors, dealers, and greenhouse manufacturers in the industry, while also operating direct distribution and stocking/service centers in Wisconsin and California. The 2012 master distribution and service partnership with Hydro Systems for Dosmatic and Chemilizer injectors is a core commercial relationship, designating Green-Tek as the North American Service/Repair Provider for horticultural and agricultural markets and anchoring the recurring parts and repair revenue stream.
