Carroll Construction Supply

What Carroll Construction Supply does

Carroll Construction Supply (legal name Carroll Distributing & Construction Supply, Inc.) is a privately held, employee-owned construction materials distributor founded in 1954-1955 by brothers Royce and Dick Carroll in Ottumwa, Iowa. The company distributes concrete forming systems, hand and power tools, safety equipment, building materials, waterproofing products, rebar and mesh, anchors and fasteners, and related construction supplies across 17 product categories, complemented by four service lines: custom rebar fabrication, equipment rental (concrete and earthmoving equipment, telehandlers, generators, aerial work platforms, and similar), trailer sales, and tilt-up construction services. Its primary customers are commercial contractors (concrete, infrastructure, and high-rise construction) and residential contractors / DIY enthusiasts, served through a horizontal segmentation approach.

The company operates a hybrid distribution model combining 34 physical branch locations across 13 states—anchored in the Midwest (Iowa, Illinois, Minnesota, Nebraska, Kansas, Missouri, South Dakota) and extended into Texas, Florida, Ohio, Indiana, Michigan, Kentucky, and Pennsylvania—with a full e-commerce platform supporting account management, NET 30 credit accounts, and guest checkout. Pricing is unit-based with a 1.5% per month service charge on past-due balances, and customer credit applications are issued at the branch level rather than centrally. Each branch is staffed by local managers providing technical product advice, and the company emphasizes job-site delivery of both stock and fabricated rebar.

Revenue is generated through hardware sales (construction materials, trailers, fabricated rebar) and managed services (equipment rental). The business is led by President Steve Carroll, a member of the founding family, and has grown primarily through organic branch openings and a long-running roll-up strategy that has integrated at least seven acquired regional operators (including Mallak Form & Supply in 1997 and six additional operators post-2000) as wholly-owned subsidiaries. The company maintains no disclosed AI, API, or proprietary technology capabilities beyond standard e-commerce functionality.

Direct peers

• Foundation Building Materials: Specialty distributor of building products, including concrete accessories, insulation, and drywall. Comparable in product mix and contractor focus, with a branch network similar in shape to Carroll's.
• US LBM: Building materials distributor serving residential and commercial contractors across the Midwest and beyond. Comparable in branch-based distribution, contractor customer base, and reliance on local market density.
• SRS Distribution: National building products distributor with an aggressive roll-up history of regional distributors. Direct peer given overlapping product categories (concrete, fasteners, tools, safety) and similar branch-based contractor GTM.
• White Cap: Largest US distributor of concrete, forming, and specialty construction supplies with hundreds of branches nationwide. Directly comparable to Carroll in core concrete/forming product mix, contractor customer base, and rebar/forming accessories.
• ABC Supply Co. National building products distributor serving contractors with a similar branch + counter + jobsite delivery model. Highly comparable GTM and customer segmentation (residential and light-commercial contractors), though broader on roofing/siding.

Emerging players

• Lansing Building Products: Regional building products distributor in the Midwest/East Coast serving contractors. Smaller and narrower product set than Carroll but comparable in target customer (exterior building products contractors) and distribution model.

Broad incumbents

• Ferguson Enterprises: Large publicly traded distributor of plumbing, HVAC, and related specialty products. Overlaps Carroll only marginally (tools, safety) but competes for contractor wallet share and represents the broader incumbent competitive set in specialty distribution.
• Sunbelt Rentals: Largest equipment rental company in North America. Comparable only on Carroll's rental revenue stream (telehandlers, aerial, compaction, generators), but at far greater scale and broader category breadth.

Regional players

• Tanco Construction Supply: Smaller Midwest-based construction supply distributor focused on concrete accessories and forming. Highly comparable niche/product overlap with Carroll but with a more limited geographic footprint.
• Capital Lumber Company: Regional lumber and building materials wholesaler. Comparable as a contractor-facing building materials distributor in adjacent categories; useful as a comp for procurement and branch economics.
