Pre-Assembly & Installation

Proprietary chemical formulas are applied by hand, developing unique, heirloom-grade finishes that complement your design vision.

Our engineers review architectural plans, ensuring structural feasibility and precise material specification before any cut is made.

From CNC plate cutting to TIG/MIG welding, all steel and bronze components are shaped and joined in our Portland workshop.

Every piece undergoes full pre-assembly and fit testing in-house, guaranteeing seamless integration on site.

Beyond Aesthetics

Structural Steel Engineering

We integrate advanced structural calculations directly into our fabrication process. This ensures every floating staircase or bronze door meets rigorous load-bearing requirements without compromising design intent.

Our approach emphasizes hidden mechanical fasteners and cold-rolled joinery, providing clean lines and superior structural integrity for high-end residential projects.
