What MALCO does

MALCO is a privately held, Oklahoma-based manufacturer of refractory anchoring systems and custom industrial fabrication services for heavy industry, founded in 1982 and headquartered in Tulsa with a 20-acre fabrication facility in Drumright. The company's core offering is a complete line of refractory anchors (brick anchors, castable wire anchors, ceramic fiber anchors and threaded products, stud weldable products, and wear-resistant hexmesh) that secure ceramic fiber, castable, and brick linings inside high-temperature equipment operating up to 2,200°F. MALCO holds ASME S, U, and National Board R stamp certifications, qualifying it to fabricate and repair pressure vessels serving petrochemical, cement, power generation, and chemical processing customers.

MALCO's fabrication business spans thermal oxidizers (direct fired, recuperative, regenerative, catalytic, RCO), regenerative thermal oxidizers (RTOs) achieving greater than 99% destruction efficiency, vapor combustor units (VCUs) from 40-120 feet, custom HRSGs, industrial burners, frac sand dryers, air filtration systems, and ceramic fiber insulation installation. The company performs all processes in-house, including plate rolling up to 18 feet in diameter, welding, sandblasting, coating, wiring, and assembly, enabling single-source delivery from raw steel to finished, ready-to-install systems. Customers include global cement majors (Holcim, Heidelberg Materials, CEMEX, CRH, UltraTech) and oil & gas operators across upstream, midstream, and downstream segments.

The business model is direct B2B project-based sales with custom quote-based pricing (no public pricing), 24/7 emergency response, and same-day anchor delivery capability. Revenue is generated through three streams: hardware sales of refractory anchor products, professional services for custom fabrication, and managed services for integrated turnkey system delivery. MALCO sells exclusively through direct engagement (phone, website quote requests, engineering collaboration) with no distributors or intermediaries, and serves customers across the United States, Canada, and Mexico. The company emphasizes responsiveness, deep alloy inventory, and capital-intensive fabrication capacity as its core competitive differentiators.

Core offering

MALCO manufactures and supplies refractory anchoring hardware (brick anchors, castable wire anchors, ceramic fiber anchors, stud weldable products, and wear-resistant hexmesh) used to secure refractory linings inside furnaces, kilns, boilers, and other high-temperature industrial equipment. The company also provides custom industrial fabrication services including thermal oxidizers, industrial burners, HRSGs, frac sand dryers, air filtration systems, vapor combustor units, ceramic fiber insulation, and ASME-certified pressure vessels, serving heavy-industry customers across oil & gas, cement, power generation, and related sectors in North America.

Product overview

MALCO is a refractory anchors and industrial fabrication company offering a portfolio of specialized products centered on refractory anchoring systems and custom-fabricated industrial equipment. The core product line includes five categories of refractory anchors (brick anchors, castable wire anchors, ceramic fiber anchors & threaded products, stud weldable products, and wear-resistant hexmesh products) that secure insulation and refractory linings in high-temperature equipment. Complementing the anchor products, MALCO fabricates thermal oxidizers (including regenerative RTOs and recuperative oxidizers), ceramic fiber insulation systems, industrial burners, frac sand dryers, air filtration systems, vapor combustor units, and custom refractory castables/forms. The company provides these as both standalone products and as fully integrated fabrication services including rolling, cutting, welding, blasting, coating, wiring, and assembly. Industries served include oil & gas, cement, power generation, pulp & paper, renewable energy & biofuels, chemical processing, air pollution/emissions control, and battery recycling.
