Who We Are

A Custom Metal Fabrication Company Built Different

Metal City Fab is a full-service custom metal fabrication company serving commercial, institutional, industrial, and architectural construction. We operate out of our fabrication facility in Warren, Michigan, with in-house engineering, project management, fabrication, and field installation capabilities under one roof.

Our team of engineers, project managers, estimators, and fabricators has built a reputation for delivering complex custom metalwork on time and to the highest quality standards. From ornamental railings and architectural structures to large-scale industrial fabrications and proprietary product systems, we execute projects that other fabricators turn down.

Construction management firms, general contractors, architects, interior designers, and developers trust Metal City Fab because we deliver consistent results, communicate proactively throughout every project, and stand behind our work long after the last bolt is tightened.

Our History

From a Fence Company to a National Fabricator

Three decades of growth, driven by a commitment to quality and an obsession with doing right by our clients.

1983

Where It Started

Len DiGrande, founder and CEO, began his career as a door-to-door salesman at King Fence & Supply Co. in Detroit. He quickly developed a passion for the trades and for building relationships with clients. His childhood best friend, Marc Rudorf, joined the King Fence team in 1986 as a laborer and installer, mastering the craft from the ground up.

1992

American Fence & Supply Co. Is Born

When King Fence's owner passed away, 27-year-old Len, Marc, and coworker Gary Oliver set out on their own. American Fence & Supply Co., Inc. opened its doors in March of 1992. Len led sales, Marc mastered estimating, and Gary ran field operations. The company found success quickly, serving both residential and commercial clients across Southeast Michigan.

2006

Expanding Into Custom Metal Fabrication

High demand for complex metalwork pushed the company beyond traditional fencing. Clients across municipal, hospital, institutional, educational, industrial, and commercial sectors were requesting fabrications far beyond gates and fences. The team began advertising its custom metal fabrication expertise under the name American Iron Works, and the project scope kept growing.

2012

Full Commercial Focus

American Fence narrowed its services to primarily commercial and industrial projects. The volume and complexity of fabrication work demanded a dedicated team, purpose-built processes, and a level of project management that matched the expectations of the largest general contractors and developers in the region.

2020

Metal City Fab Launches

Demand for high-quality custom metal fabrication reached a point where it warranted its own brand, its own team, and its own identity. Metal City Fab launched as American Fence's first subsidiary, dedicated entirely to custom metal fabrication for commercial and architectural construction. Within its first years, MCF became one of the region's most trusted fabricators, serving hundreds of clients including some of the largest and most recognized names in construction, development, hospitality, and higher education.

Today

Design-Build Fabrication at Scale

Metal City Fab operates as a full design-build metal fabrication company with in-house engineering, estimating, project management, fabrication, finishing, and field installation. With four proprietary product lines and a portfolio spanning railings, structures, gates, stairs, signage, artwork, and industrial fabrications, MCF serves clients across multiple states and industries.

Full-Service Capabilities

Everything Under One Roof

We do not outsource the critical steps. Every phase of your project is managed and executed by our own team, in our own facility, to our own standards.

Estimating

Our estimating team reviews your drawings, assesses scope, materials, and quantities, and delivers a detailed proposal. We respond to most bid requests within 24 hours.

Engineering & Pre-Construction

Our pre-construction department develops shop drawings and PE-stamped structural calculations. We offer value-engineering options to optimize cost without compromising design intent.

Project Management

A dedicated project manager coordinates your fabrication from submittal through closeout. Proactive communication, schedule tracking, and quality control at every milestone.

Fabrication & Production

Your project is fabricated in our controlled shop environment by skilled welders, fitters, and finishers. Every piece is built to tolerance, quality-checked, and prepared for finishing before it leaves our facility.

Quality Control

Every fabrication goes through rigorous quality control before it leaves our shop. Welds, dimensions, finishes, and fitment are inspected against the approved shop drawings. Nothing ships unless it meets our standards.

Delivery & Installation

Our field crews deliver and install your fabrication, ensuring the job site is left in better condition than when we arrived. We handle all required closeout documentation and stand behind every installation.

Materials We Work With

Full Range of Metals & Finishes

We work with the complete spectrum of metals to match the design intent and performance requirements of your project. If you can spec it, we can fabricate it.

We combine materials and infill types within a single system to achieve any design intent.
