What The Diez Group does

The Diez Group (legal name Delaco Steel Corporation) is a family-owned, Hispanic Minority Business Enterprise (MBE) and Women's Business Enterprise (WBE) certified U.S. metal service center group founded in 1973 by Geraldo Diez, Sr. The group operates 9 production and warehouse facilities across 6 U.S. states (Michigan, Indiana, Missouri, Iowa, and New York), with its headquarters in Dearborn, MI. Its customer base is anchored in Tier 1 North American automotive OEMs — Ford, General Motors, Chrysler (Stellantis), and Honda — as well as Johnson Controls International (JCI), with whom it holds multi-decade supplier relationships evidenced by 10+ customer awards, including the Ford Q1 (1997, the first minority steel service center so honored), GM Supplier of the Year, Chrysler Pentastar, and Ford World Excellence Award for Diverse Supplier of the Year.

The group's core manufacturing platform spans precision blanking (250–1000 ton presses, bed sizes up to 108" x 204") for exposed and unexposed aluminum and steel, precision slitting, cut-to-length (CTL) lines, scallop blanking, and milling. It has built out an integrated laser welded blank (LWB) capability across Dearborn (IPG 5KW fiber laser + Rofin 8KW CO2 laser cells with Fanuc automation and TEMATE ultrasonic NDT), Montezuma, IA (fully automated Soutrac linear/non-linear welding with IPG fiber laser and inline Souvis NDT), and Tonawanda, NY (Delaco AMTB). Quality and environmental systems are certified to IATF 16949 and ISO 14001 across blanking, slitting, milling, laser welded blank manufacturing, and warehousing/logistics of Class 1 & 2 metals.

The Diez Group generates revenue through toll-processing contracts and value-added sales of aluminum and steel blanks, slit coils, and laser welded blanks, supplemented by warehousing and JIT logistics services delivered via Delaco Integrated Terminals (D.I.T.) — operating ~251,000 sq. ft. of climate-controlled warehousing across Woodhaven, MI (185,000 sq. ft., 24/7, owned fleet) and Kansas City, MO (66,000 sq. ft.). Pricing is quote-based and negotiated per OEM/Tier 1 contract; no public pricing or revenue figures are disclosed. The company pursues an enterprise field sales motion supplemented by a direct corporate website (thediezgroup.com) with plant-level capability pages and dedicated contact emails/phones at each facility, targeting procurement teams at major OEMs. Supplier diversity procurement programs at the OEMs (which target >6% MBE/WBE sourcing) are a structural feature of the customer relationship.

Revenue model

1. Aluminum and Steel Sales, Service, and Logistics: Core revenue is generated from toll-processing and sale of aluminum and steel blanks, slit coils, laser welded blanks, and value-added warehousing/logistics to industrial customers (predominantly automotive OEMs and Tier 1 suppliers). The Diez Group runs precision level blanking (exposed, unexposed, scallop, straight, configured), cut-to-length (rectangles, trapezoid, chevrons), laser welding, slitting, washing, oiling, and warehousing of coils up to 96" OD and 75,000 lbs, indicating a contract/toll manufacturing revenue model rather than commodity resale.
2. Minority Business Enterprise (MBE/WBE) Supplier Premium: As a Hispanic MBE & WBE certified supplier group, the company benefits from supplier diversity procurement programs at major OEMs (Ford, GM, Chrysler, Honda, JCI), which carry over 6% of total purchases sourced from other MBE/WBE/Veteran suppliers — supporting a supplier-diversity driven revenue stream tied to OEM sourcing policies.
