OmniMax International

What OmniMax International does

OmniMax International is a U.S.-headquartered manufacturer of residential building products, specializing in roofing accessories and rain-carrying (gutter, downspout, flashing, soffit/fascia) systems manufactured from aluminum, steel, vinyl, and copper. The company runs a portfolio of seven complementary brands — Amerimax, Berger Building Products (since 1874), Flamco (since 1923), Verde Industries, Millennium Metals, Hancock Enterprises, and Nu-Ray Metals — collectively representing over 150 years of combined industry experience, and operates 17 manufacturing facilities across the U.S. and Canada. Its core manufacturing technology spans roll forming, brake pressing, embossing, and vinyl extrusion, with a closed-loop plastics recycling process that reclaims nearly all in-house scrap back into production. The product portfolio also extends to outdoor living structures (Equinox Louvered Roof systems, Alumawood patio covers, vinyl railing under Yardcrafters and ProDeck) and to selected commercial and recreational vehicle applications.

The business model is B2B hardware sales through multi-channel distribution: home center retailers (including Home Depot and similar national home improvement chains), wholesale roofing and building material distributors, lumberyards, co-ops, and two-step distributors. Revenue is generated through quote-based pricing to distributor and retail partners rather than published consumer pricing. Primary customer segments are residential contractors, builders, and DIY homeowners served through retail channels, with secondary exposure to commercial construction, outdoor living consumers, and RV OEMs. The company was owned by Strategic Value Partners from October 2020 and was acquired by Gibraltar Industries in February 2026 for $1.335 billion, at which point expected 2025 adjusted net sales were $565 million and adjusted EBITDA was $110 million (~19.5% margin), with Gibraltar projecting $35M of cost synergies by end of 2028. Following the acquisition, OmniMax now operates within Gibraltar's Residential segment, which represents over 80% of Gibraltar's total revenue.
