Structural block can be used to create beautiful fences in landscape projects.

However, their primary use is in masonry walls for buildings or enclosures.

We have a large selection of structural block sizes manufactured with either lightweight or concrete aggregate.

We stock 4", 6", 8", 12" structural blocks in full sizes, half sizes, and knockouts. Our 8" lightweight also comes in a "split face".

Our stock color is gray, however, we can run custom colors if the job is large enough.

Please contact us with any questions regarding our structural block.
