About Us

System USA, Inc. of Watsonville, California, works in close cooperation with well-known Dutch greenhouse manufacturer Ammerlan Construction B.V. in Horst, Netherlands, to design and construct a range of glass, acrylic, and polycarbonate custom greenhouses in both standard and custom sizes. We have decades of greenhouse manufacturing and construction experience; and since 1981, have set the standard for excellence in modern, complete and efficient greenhouse facilities.

Because we manufacture all of the steel and aluminum pieces in our own Netherlands and Watsonville, California, warehouses, we can take custom orders. We make it easy to get exactly what you want for your backyard greenhouse, allowing you to extend your growing season.

We're known for manufacturing the popular BKT rack and pinion system, and for the special attention we pay to greenhouse covering materials. While our primary market is large growers, we also offer smaller greenhouses for family growers. Our polycarbonate, acrylic sheets, and low-iron tempered glass are all double-glazed for durability; and our skilled builders are available to securely mount your pre-fabricated construction and glazing systems.
