SIC Code 3271-02 Description (6-Digit)

Cinder block manufacturing is a subset of the concrete block and brick manufacturing industry. Cinder blocks are made from a combination of cement, water, and aggregates such as sand, gravel, or crushed stone. The mixture is poured into molds and left to cure, resulting in a sturdy and durable building material. Cinder blocks are commonly used in construction for walls, foundations, and retaining structures due to their strength and affordability.
