Who We Are

NGMA is a professional trade organization for the manufacturers and suppliers of greenhouses and greenhouse components.

It’s one thing to manufacture a greenhouse. It’s quite another to actually build it to codes specially for a grower’s needs. For just that reason, the NGMA membership brings together some of the most experienced and knowledgeable manufacturers in the industry.

NGMA members are committed to building greenhouses with a level of professionalism you won’t find anywhere else.

NGMA structural members are more than just greenhouse builders, they are the leading edge of the latest technology. So if you’re looking for the best greenhouse or component manufacturers North America has to offer, contact NGMA. Be a part of the most extensive list of engineers, dealing with horticulture, agriculture, building, structural, growing and design issues the industry has to offer!
