What Is Metal Fabrication?
Metal fabrication is the process of turning raw metal into usable, project-ready components. It involves:
-
Cutting, drilling, and coping
-
Bending and forming
-
Fitting and welding
-
Grinding, prepping, and finishing
These steps transform steel into beams, columns, brackets, stair stringers, handrail posts, balcony frames, pergola members, and countless other pieces needed to complete your project.
Done right, metal fabrication means:
-
Components that fit in the field
-
Connections that meet code and engineering requirements
-
Welds and finishes that hold up to weather, wear, and inspection
That’s the level of fabrication we provide at J&M Welding Inc.

Architectural Elements: Handrails, Staircases, Pergolas & Balconies
Many architectural features start in the fabrication shop. We build:
-
Steel Staircases & Stair Towers – Interior and exterior stairs for commercial buildings, multi-story homes, wineries, and industrial facilities.
-
Handrails & Guardrails – Custom systems designed to meet code while complementing the architecture of the space.
-
Balconies & Balcony Frames – Structural and decorative balcony assemblies, including posts, rails, and support brackets.
-
Steel Pergolas & Shade Structures – Modern steel pergolas, trellises, and canopies for outdoor spaces, patios, and courtyards.
These components often tie directly into our Architectural Steel services, with fabrication handled in-house for quality and consistency.
