Stoncor Group

What Stoncor Group does

Stoncor Group is the Canadian operating identity of a specialty coatings and infrastructure protection business consolidated under three established sub-brands: Stonhard (manufacturer and installer of seamless epoxy floors, walls, linings and parking deck solutions), Fibergrate (fiberglass reinforced plastic / FRP molded gratings and structural products), and Carboline (protective coatings, linings and fireproofing systems). The legal entity referenced in policy documents is 'StonCor,' and the corporate parent is RPM International Inc., a publicly traded diversified coatings and specialty materials group headquartered at 2628 Pearl Road, Medina, Ohio. Operations are delivered coast-to-coast across Canada through brand-specific distribution centers, with both English- and French-language web properties supporting national reach.

The company's product technology rests on three distinct specialty materials platforms rather than a single unified architecture. Stonhard's core competency is high-performance seamless epoxy systems installed by in-house crews for industrial and commercial facilities. Fibergrate's platform is molded FRP grating and structural shapes engineered for corrosion resistance. Carboline's portfolio is applied coating, lining and fireproofing systems designed to protect infrastructure in demanding industrial environments. The digital surface is conventional B2B: brand-specific websites, Pardot for Salesforce marketing automation, and Google Analytics for engagement tracking—no proprietary AI, APIs, SDKs, or developer integrations are offered.

Commercially, Stoncor runs an enterprise field sales motion in Canada, supplemented by direct distribution and engineering support personnel aligned to each brand. Pricing is not publicly disclosed and appears to be quote-based, consistent with project- and specification-driven procurement in industrial coatings and gratings. Revenue derives from two streams: hardware and materials sales (specialty coatings, sealants, building materials) and project-based professional services (manufacturing, installation, and engineering support). The company serves industrial and commercial infrastructure customers in Canada; no end-customer logos, segment splits, or concentration data are disclosed.

Broad incumbents

• RPM International Inc. RPM International is the publicly traded parent of Stoncor Group and the broader portfolio that includes Stonhard, Fibergrate, and Carboline globally. As the ultimate parent, RPM's consolidated financials and strategy directly drive Stoncor's capital allocation, brand investment, and growth ceiling.
• Sherwin-Williams: Sherwin-Williams is the largest North American coatings company with a significant protective and marine coatings division that overlaps directly with Carboline's product range. It competes for the same industrial and commercial infrastructure specification projects and brings greater scale and distribution density.
• PPG Industries: PPG's industrial coatings segment serves the same protective coatings and linings market as Carboline, with strong positions in oil & gas, marine, and infrastructure. PPG's global R&D and direct specification relationships with engineering firms create direct competitive overlap in Stoncor's core end-markets.
• AkzoNobel (International Protective Coatings): AkzoNobel's International Protective Coatings division is a global leader in corrosion protection, fire protection, and linings for industrial assets. It overlaps significantly with Carboline's protective and fireproofing coatings portfolio and competes on large multinational infrastructure projects.

Direct peers

• Strongwell Corporation: Strongwell is a leading North American manufacturer of pultruded and molded FRP products including gratings, handrails, and structural shapes. It directly competes with Fibergrate in the FRP molded grating market for industrial platforms, walkways, and catwalks in corrosive environments.
• Tnemec Company: Tnemec is a US-based protective coatings manufacturer focused on industrial and architectural applications, including infrastructure protection. It competes head-to-head with Carboline for the same specifier-driven, project-based protective coatings business.
• Sika AG: Sika is a global specialty chemicals company with a substantial flooring, sealing, and bonding product portfolio that competes directly with Stonhard's resinous flooring systems. Sika's target customers — industrial and commercial facilities requiring seamless floors, walls, and protective systems — closely mirror Stoncor's customer base.
• Bedford Industries (FRP Division): Bedford Industries operates a competing FRP molded grating business under similar applications. As a focused FRP specialist, it competes for the same corrosion-resistant industrial platform and walkway specifications served by Fibergrate.
• Flowcrete (RPM/Tremco): Flowcrete is a resin flooring specialist (also within the RPM family of brands) offering seamless epoxy, polyurethane, and MMA flooring systems. It is a direct substitute for Stonhard's product line and competes on the same industrial and commercial project specifications.
• Tremco Incorporated: Tremco (also an RPM family brand) provides construction sealants, waterproofing, and resinous flooring products that directly overlap with Stonhard's seamless floors, walls, linings, and parking deck solutions. It shares Stoncor's distribution channels and serves overlapping industrial and commercial customers.
