Expanded Metal Benching

Expanded metal benches are most commonly used for propagation spaces, retail applications, or to support a drip system fed potted crop. 

Zwart Systems benches can be constructed directly on ground cover, they can be supported by a post hole, or benches can be fastened to the concrete floor.

Benches are available as stationary, rolling, or gliders.

No size is out of the question as every bench is custom-made to suit your layout.

From the Ground Up

At Zwart Systems, we offer complete design, manufacturing, installation, and service of all our products. We can help create a system that's right for you.

Expanded Metal Overview

Bench Construction

  • Height Adjustable

    All benches have 6-8 inches of height adjustment in the legs so growers can accommodate an uneven floor. The frame structure used in expanded metal benching is the same style as is used for flood benching and trough benching. No size is out of the question as every bench is custom made to suit your layout.

  • Materials

    Zwart benches are constructed using aluminum side profile, anti-tip mechanisms, roller stops, and durable HDPE formed corners that completely cover the rough edges of the expanded metal to finish the bench. Expanded metal tops are available in two different finishes, raised expanded metal or flattened.

    Raised expanded metal is stronger, while flattened expanded metal is nice for sliding trays without experiencing table snag. Cross supports on raised expanded metal tables are spaced at 24 inches. 16-inch spacing is required for flattened metal installations to maintain the same level of table strength.

  • Installation

    Installation is quite simple - you can do it yourself, or a Zwart installation team can come in and install your new benches for you. Smart, simple, durable benching. 

    Every bench package comes with a complete set of drawings and assembly instructions - a video reference is also available for reference. A drill, a 1⁄2-inch wrench, and a rubber mallet are the only tools you will need.
