Paper first

Drawn before it is made.

Every opening is dimensioned and approved on paper before the shop cuts any steel. Open a sheet to read it at full size.

What to expect

Each step closes before the next begins.

So the design, the shop and the site never drift apart.

What to send us

  1. 01

    Share the opening

    A plan, an elevation, a photograph or a rough size is enough to begin. Send what you have; we ask for the rest.

  2. 02

    Confirm the scope

    Operation, quantity, glass, hardware, finish and site conditions are agreed, and the opening is measured in the field.

  3. 03

    Develop the drawing

    Shop drawings are drawn against your elevations or your architect’s documents: proportion, structure, hardware zones, glazing and every condition around the opening.

    Final confirmation & scheduling

    The drawing, finish sample, glass, hardware, scope and schedule are approved before fabrication.

  2. 05

    Made in our Dallas shop

    The shop cuts, welds, finishes and glazes the work and checks its geometry against the approved set. Fabrication is typically 8–12 weeks after drawing approval.

  3. 06

    Quality check

    Every piece is reviewed against the approved drawing before it leaves the shop.

  4. 07

    Set in place

    Our own crew delivers, sets, glazes and adjusts the work on site, and protects it until the job is done.
