What Kind of Stair Manufacturer Is The Iron Shop?

A Manufacturer that Improves Space Efficiency with Staircases

Operating as a manufacturing division of M. Cohen and Sons, Inc., The Iron Shop maintains a 130,000-square-foot facility in Broomall, Pennsylvania. Housing in-house CAD detailing, CNC metal forming, structural welding, and finishing operations under one roof, the company delivers space-efficient stair systems engineered for compact indoor and outdoor footprints.

A Product Lineup Covering Indoor, Outdoor, and Specialty Designs

The Iron Shop processes multiple structural alloys and infill materials, including ASTM A36 carbon steel, 6061-T6 structural aluminum, cast aluminum (Victorian series), solid hardwoods, and composite decking. Products are shipped as pre-engineered modular knock-down kits designed to comply with IRC and IBC statutory stair geometry and point-load ratings.

Their knock-down distribution model allows component crates to be hand-rigged through standard interior doorways and freight elevators without requiring crane mobilizations or exterior wall openings.

The Iron Shop is suited for residential homes, lofts, rooftop decks, basements, multi-family amenity spaces, and light commercial secondary access routes where floor space is limited and straight staircases are impractical. Their pre-engineered modular kits accommodate both professional contractor installations and custom architectural builds.

On our media platform, we compare and introduce recommended manufacturers by application, so please feel free to use it as a reference when selecting your products.

Objective Analysis: Strengths and Considerations of The Iron Shop

Core Strengths (Pros)

• Domestic Industrial Heritage & Vertically Integrated 130,000 Sq. Ft. Facility: Operating in Broomall, PA since 1931 under M. Cohen and Sons, Inc., maintaining ~125 in-house personnel, PE-stamped drafting capabilities, CNC metal forming, and complete domestic quality control.
• Parametric Multi-Material Fabrication Scope: Offers broad material selection across carbon steel, structural 6061-T6 aluminum, lightweight cast aluminum (Victorian series), solid hardwoods, and composite Trex infills for open-riser floating and spiral designs.
• Standardized Code Compliance & Knock-Down Modular Distribution: Pre-engineered to fulfill IRC and IBC statutory dimensions and 300 lb point-load criteria, shipping flat-pack modular kits that navigate standard doorways without mobile crane mobilizations.

Potential Drawbacks or Considerations (Cons)

Secondary Architectural Access Focus vs. Primary Structural Framing: Tooling and plant operations (CSI 05 51 00 / 05 71 00) are dedicated to secondary stair assemblies rather than primary wide-flange structural steel building skeletons under CSI Division 05 12 00.

Egress Occupancy Restrictions & Jobsite Mechanical Joinery Control: Relies on modular mechanical slip connections requiring verified jobsite torque control, while IBC Section 1011.10 limits spiral staircases from serving as primary egress routes for commercial spaces exceeding 250 sq ft or 5 occupants.

Company Information

Summary: Is The Iron Shop the Right Fit for Your Project?

The Iron Shop serves as an established manufacturing partner for architects, general contractors, and residential developers seeking space-efficient secondary access systems. Operating out of a centralized Broomall, Pennsylvania facility, the company combines 90-plus years of metalworking history with parametric design and nationwide modular kit distribution.

While primary structural steel framing or high-capacity commercial egress cores require heavy structural mills or pre-welded pan stair fabricators, The Iron Shop's multi-material capability, IRC/IBC code compliance, and flat-pack freight logistics make them a practical choice for secondary vertical circulation, loft access, and exterior deck connections.

Compare with Other Leading Manufacturers

To ensure you select the optimal partner for your structural or architectural needs, comparing multiple fabricators based on their service reach, engineering capabilities, and product specialties is strongly advised.
