Colossus Building Block
At RealTuff Builders, we offer a variety of colossus building blocks that you can conveniently purchase either in loose quantities or packaged in crates (168 blocks) for your construction needs. They are the perfect blocks for load bearing applications such as building foundations and external perimeter walls.
6” vertical core block ideal for load bearing applications such as building foundations and external perimeter walls.
*Nominal Size: 6” x 8” x 16” (see description for further information)
Actual Size: (140mm x 190mm x 390mm)
Blocks per pallet: 168
*Nominal Size: In manufacturing, a nominal size or trade size is a size “in name only” used for identification. The nominal size may not match any dimension of the product, but within the domain of that product the nominal size may correspond to a large number of highly standardized dimensions and tolerances.
