Before you call

Structural steel: the short version

Steel beams, columns, platforms and mezzanines, built to drawings and often installed.

When you need it

  • Columns, posts and lintels
  • Mezzanines, platforms and canopies
  • Commercial and multi-unit builds

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

Typical lead time

Ask for fabrication and installation dates after the shop reviews your engineer's drawings.

    Who supplies the engineered drawings?

  3. Q3

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. Ask for its current certification.

What do I send for a beam quote?

Send your engineer's drawings, measurements, photos and access details. Specify supply only or supply and installation.

What should I confirm before ordering?

Ask who supplies the drawings, finish, delivery and installation. Check with your town before starting the work.

Good to know

  • Ask your engineer to specify the beam and connections before you order.
  • No South Shore shop we checked posts prices for this. Send a request to compare quotes.
