Construction Materials

What Construction Materials does

Construction Materials, Inc. (CMI) is a privately held, Upper-Midwest fabricator and distributor of construction materials founded in 1961 in Minneapolis and operating across three facilities in Minneapolis (MN), Cedar Rapids (IA), and Des Moines (IA). The company provides fabricated reinforcing steel (rebar), concrete paving products (dowel bar assemblies, metal keyway, loose dowels, paving forms), a broad line of concrete construction consumables (forming tubes, finishing tools, joint sealants, waterproofing, floor coatings, sealers, grouts, epoxies), and geotextile/erosion-control products organized into CSI Divisions 2, 3, and 7. CMI also distributes the OnCrete™ decorative concrete sub-brand out of Cedar Rapids.

The underlying technology is conventional for the sector: in-house CAD-based detailing for reinforcing steel and concrete form drawings, in-house fabrication at each regional location, and large on-hand inventories enabling jobsite delivery of DOT-approved products. There is no proprietary software platform, no API, and no AI/ML capability disclosed. Value-add engineering support and hands-on field assistance are positioned alongside product supply as core deliverables.

CMI sells predominantly on a project-by-project, one-time basis to contractors, architects, engineers, and public agencies across federal, state, county, city, and private infrastructure and commercial builds. Pricing is not publicly disclosed. The go-to-market is sales-led and field-based: long-tenured sales staff and estimators at each branch, supplemented by rebar detailing and engineering support. The company is founder/management-owned, with no institutional, PE, or VC backing indicated, and is led by President Dick Galligan (the fourth president since 2011), VP Ray Marvin, Treasurer Chris Stebral, and Secretary Duane Jaeb.

Direct peers

• Commercial Metals Company: Commercial Metals Company (CMC) is one of the largest U.S. rebar fabricators and steel producers, directly comparable to CMI's fabricated reinforcing steel operations. Through its acquisition of Harris Rebar, CMC operates a national fabrication network serving DOTs, contractors, and infrastructure projects — the same customer set and product category as CMI, but at national scale.
• Gerdau Ameristeel: Gerdau is a leading North American long-products steel producer and rebar fabricator with extensive fabrication operations serving highway, commercial, and industrial construction. Directly comparable to CMI on rebar fabrication, customer base (DOTs and contractors), and product offerings, though at substantially larger scale.
• Harris Rebar: Harris Rebar (now operating within Commercial Metals Company) is the largest rebar fabrication and installation company in North America, directly competing with CMI in fabricated reinforcing steel supply to highway and commercial projects. Closest functional peer on rebar detailing, fabrication, and DOT project delivery.
• Dayton Superior: Dayton Superior is a leading manufacturer of concrete construction accessories, forming products, and rebar-related materials, directly overlapping with CMI's Division 3 (Concrete) and reinforcing steel accessories lines. Comparable on customer base (commercial and infrastructure contractors), product mix (forming tubes, accessories, joint sealants, grouts, epoxies), and channel (construction materials distribution).
• White Cap (formerly HD Supply Construction Supply): White Cap is a large national distributor of concrete, rebar, forming, and specialty construction materials serving concrete contractors and infrastructure projects — directly comparable to CMI's distribution model across rebar, concrete accessories, geotextiles, and erosion control products, though at national scale.
• Forterra: Forterra is a major manufacturer of concrete and masonry building products, including pipe, precast, and concrete accessories, serving infrastructure and construction end markets. Comparable to CMI on concrete construction materials, infrastructure project supply, and DOT customer base, though focused more on heavy concrete products than rebar fabrication.
• ABC Supply Co. ABC Supply is a national distributor of building and construction materials (including concrete forming and accessories) serving contractors across the U.S. Comparable to CMI on the construction materials distribution business model, contractor customer base, and product breadth, though with a national footprint and a roofing/exterior building products emphasis.

Broad incumbents

• Nucor Corporation: Nucor is the largest U.S. steel producer and a vertically integrated rebar manufacturer with fabrication capabilities serving construction and infrastructure end markets. Broad incumbent competitor in the same upstream steel and rebar value chain as CMI, but with mill-level scale and a much broader product portfolio.
• Steel Dynamics: Steel Dynamics is a major U.S. steel producer with significant rebar and structural steel output serving construction end markets. Broad incumbent operating in CMI's upstream steel supply chain, with overlapping exposure to highway and commercial construction demand cycles.

Regional players

• Boise Cascade Company: Boise Cascade is a major manufacturer and distributor of engineered wood products and building materials serving residential and commercial construction markets in the U.S., with significant Midwest presence. Regional adjacency to CMI's geography and overlapping customer base among upper Midwest contractors, though operating primarily in wood-based building materials rather than concrete and rebar.
