What Metalloy does

Metalloy Inc. is a Houston, Texas-based custom manufacturer founded in 1967 that produces precision, high-temperature, high-strength fittings and flanges from exotic alloy materials for the petrochemical, marine, and offshore industries. The company's product portfolio spans adapters, bosses, block pattern fittings, branch outlets, brazolets, bushings, caps, couplings, flanges (including RTJ, Weldneck, Threaded, Socketweld, Slip-on, and Blind configurations), inserts, king nipples, pipe nipples, pigtails and ventures, reducers, stub-ends, swages, and unions. Products are manufactured from materials including Copper Nickel, Chrome-Moly, Monel, Hastelloy, Inconel, Brass, Alloy 20, Incoloy, Stainless Steel, Bronze, Aluminum, and Titanium. Manufacturing capabilities include closed-die and open-frame forging, heat treating, normalizing, machining, and in-house material certification with laboratory testing, mill test reports, grain size reports, and heat treating charts maintained and made accessible to customers. CNC machinery enables large production runs while preserving precision manufacturing standards, and AUTO CAD software is used to translate customer sketches or sample parts into manufacturing blueprints.

The company operates a custom B2B enterprise model with no public pricing — all quotes are generated on a per-order basis. Revenue derives from one-time custom manufacturing orders that include material certification and traceability. Distribution is exclusively direct-to-customer via toll-free phone (1-800-828-0500) and a team of dedicated sales representatives (Denny Sullivan, Sheila McKinney, Reba Ham, Fanoel Gutierrez); no intermediaries, distributors, or e-commerce channels are used. The customer base is concentrated in two verticals: marine/offshore (shipyards, marine OEMs, U.S. Navy vessels and submarines, and U.S. Coast Guard applications) and petrochemical/chemical (refineries, chemical plants, and petrochemical furnaces operating in severe and highly critical environments). Metalloy maintains a proprietary library of U.S. Navy and U.S. Coast Guard approved drawings as well as hundreds of standard marine component drawings, supporting qualified supplier status for government marine contracts.

Digital presence is minimal: a product catalog website plus LinkedIn and Facebook pages, with no content marketing, paid advertising, event marketing, or installed software product. The company is described as internationally recognized and serves customers worldwide, though no specific non-U.S. offices, customer wins, or international distribution arrangements are disclosed. Ownership is private and closely held with no disclosed external investors, parent company, or institutional shareholders. No patents, trademarks, funding rounds, acquisitions, leadership changes, AI/ML capabilities, or third-party software integrations are documented in the available material.
