Alweco

What Alweco does

Alweco Scherminstallaties BV (trading as ALWECO) is a Dutch privately-held company founded circa 1988 in Maasdijk, Netherlands, specializing in the design, installation, renovation and maintenance of greenhouse screen systems for horticultural growers worldwide. The company builds horizontal, vertical, roof-roll and ridge/baffle screen installations used for energy saving, climate control, blackout (light exclusion), insect protection and airflow management in commercial greenhouses. Its product portfolio is augmented by a small set of proprietary components — the Ultra Power Clip, the patented Ultra Groove Cable Drum, and the Multi Clamp — which are integrated into custom screen systems and used alongside third-party climate-screen fabrics from manufacturers such as Ludvig Svensson and Ridder Climate Screens.

The company operates a project-based, sales-led go-to-market: in the Netherlands and broader Europe it sells through an internal direct sales team, while international delivery is executed via a network of country agents (Hortère Conseil in France, Powerplants in Australia, Vegtech/Netafim in South Africa) and through partnerships with greenhouse builders and installers. Revenue is generated from custom installation projects (priced per quote on multi-year projects) and from a webshop supplying common replacement parts and components. Customer concentration is heavily weighted toward mid-to-large commercial greenhouse operators in horticulture — vegetables, flowers, potted plants, strawberries, and increasingly medicinal cannabis — with reference projects spanning the Netherlands, Belgium, France, Germany, Sweden, the UK, Portugal, Israel, Japan, Canada, Australia, South Africa and the United States.

The business is family-owned by the Alsemgeest family, who occupy most senior operational roles, and operates from two adjacent sites on Honderdland in Maasdijk: a headquarters and a separate storage and execution facility completed in 2019. Leadership includes founder Leo Alsemgeest as advisor, Stephan Alsemgeest as Managing Director/CEO, and Jeroen van Gaalen as Managing Director Sales Europe.
