We fabricate structural steel components to spec from our Newton, NJ shop — beams, columns, base plates, connection hardware, and custom assemblies built for commercial and industrial applications.
Our field crews handle structural steel erection for commercial, industrial, and institutional projects across Northern New Jersey — from single-story builds to multi-story structural frames.
We fabricate and install structural steel stairs, pan stairs, and code-compliant railing systems for commercial and industrial buildings, both as standalone scopes and as part of larger structural packages.
Lintels, bollards, embed plates, angle iron, pipe supports, equipment pads — we handle the miscellaneous iron scope that keeps a project moving without sending you to a separate vendor.
We supply and install open-web steel joists and metal roof and floor decking for commercial and industrial structures, coordinated with your structural drawings and erection schedule.
For projects without complete steel drawings, we work from architectural plans or owner requirements to produce shop drawings, details, and connection designs — then fabricate and erect to our own package.
Magro and Sons Steel operates our own fabrication shop in Newton, New Jersey, giving us direct control over material procurement, fabrication quality, and delivery schedules from day one. When you source your steel through us, you're not waiting on a third-party shop or managing a separate sub relationship; the same company detailing your drawings is cutting, welding, and delivering the steel. That means fewer handoff failures, tighter schedules, and a single point of accountability from shop floor to final bolt-up.
