Beaver Plastics Styroblock Containers

Superblock™ Containers are the mainstay of Beaver's container growing system and the industry standard with smooth, tightly fused cavities, diverse configurations, and the lowest cost per seedling. Superblock containers are the most popular tray in silviculture nurseries.

Copperblock™ Containers are manufactured with Beaver Plastics' patented Differential Coating Technology. Differential (strip) coating gives growers all the lateral root growth expected from a copper enhanced root system, while at the same time allowing the right proportion of vertical root growth desired for a cohesive plug.

Copperblock containers work by inhibiting root elongation on contact with the copper lined strips on the container wall. Roots that come into contact with the non-copper regions of the cavity are directed downward. The combination of copper enhanced roots and non-copper enhanced roots gives a firm, balanced root system that is ready to grow.

The Styroblock Container System is flexible. Developed by professional foresters, researchers, forest nurseries, and Beaver Plastics, Styroblock containers have the ability to be modified easily and economically. If you have a novel container requirement, we can make it happen.
