Your drawing does not leave this building

  • NDA first — your template or ours, signed before the first file
  • One roof, no handoffs — machining, heat treatment, coating and inspection in-house
  • No sub-contracting — the drawing is never sent to an outside shop
  • An engineer reads your drawing and writes back within 24 hours
  • Civil programs only
  • No instant prices: a real quote follows the drawing, material and quantity

NDA first if you prefer — say so in the description and we will send ours before you send anything.

FAQ

Q: What file formats can I upload?

STEP, DWG, DXF, PDF, IGES — or a photo of a marked-up print. Zip larger sets; single files up to 200 MB.

Q: How quickly will an engineer reply?

Within 24 hours. An engineer — not a salesperson — reads the drawing and writes back with manufacturability feedback.

Q: Can we sign an NDA before sending drawings?

Yes — your template or ours, signed before the first file. Say so in the description and we will send ours first.

Q: Why is there no instant price?

A real quote follows the drawing, the material and the quantity. Instant prices would be guesses, and guesses are not worth sending.
