Superior Block Co

What Superior Block Co does

Superior Block Co. is a family-owned concrete masonry manufacturer and full-line building materials distributor headquartered in Houghton, Michigan. Founded in 1946 by Dan Lorenzetti as a partnership and incorporated in 1978, the company operates under continuous Lorenzetti family ownership and currently runs a single production facility on Isle Royale Sands capable of producing over 6,000 blocks per day (approximately 500,000 blocks annually). Its core manufactured product lines include standard concrete blocks (Series 100 through 1600 plus chimney blocks), architectural blocks (Split Face, Split Fluted, Scored, Castle Rock, and the Jacobsville Designer Series with BlockStone/RockStone/RedStone variants), StoneWall SELECT retaining wall blocks, and PAVER-LOK interlocking pavers. The Jacobsville Designer Series in particular reflects domain specialization — aggregates and colors blended to simulate the Lake Superior region's historic Jacobsville sandstone quarry.

The business operates a hybrid manufacturer-distributor model: in addition to its four manufactured product lines, the company resells more than 25 third-party brands spanning bagged cement/mortar (Quikrete), doors and windows (Plyco, Northview), glass block (Seves), concrete patching (Euclid Chemical), insulation (Dow STYROFOAM), fireplaces (Wilkening, Kozy Heat), masonry tools (Kraft Tool, Crick Levels, Marshalltown), manufactured and natural stone (Boral, Eldorado, Realstone, Buechel), brick (Bowerston, Robinson, Hanson, Hebron, OCHS), insulated concrete forms (LOGIX ICF), and aggregates (sand, gravel, topsoil). All sales run through a single showroom and warehouse facility at 47515 US-41, Houghton, MI, with quote-based pricing — no public price list is disclosed — and transactions handled by phone or email. The go-to-market is sales-led, targeting three named customer segments: contractors, DIY homeowners, and landscapers, with the Western Upper Peninsula as the primary service area and ad hoc national shipment as products are "used in projects around the country." The company has no public revenue, no external funding, no parent company, and operates with a reported 1-10 person headcount.
