What to send the shop

  • Engineer's drawings, if you have them
  • Measurements and photos of the space
  • The beam size or load, from your engineer
  • Indoor or outdoor, and the finish
  • Supply only, or supply and install

Questions

Structural steel FAQ

Does the fabricator need CWB certification?

For welded structures built to CSA S16, the fabricator must be CWB certified in Division 1 or 2, says CWB.

What should I send for a beam quote?

Send your engineer's drawings, photos and measurements. State whether you need supply only or installation, and ask who handles delivery and site access.

What should the quote include?

Ask for material, fabrication, finish, delivery and installation to be listed. Confirm who supplies engineered drawings and handles any required approvals.

Good to know

  • Ask who provides engineered drawings before you order a beam.
  • No London shop we checked posts prices for this. Send a request to compare quotes.
