02 Overview
Everything that gets welded rather than cast. Equal and unequal angles, channels, I-beams, flats, squares and chequered plate — stocked in the sections that trusses, sheds, gates and mezzanine floors actually consume, and cut to length where the section allows.

05 FAQ
Structural Steel — your questions
Do you cut sections to length?
Yes, for most angles, channels, flats and plate. Cutting charges depend on the section and the number of cuts — confirm at the counter when you order.
What is the difference between ISMB and ISMC?
ISMB is an I-section beam, strong about its major axis and used for spanning. ISMC is a C-shaped channel, used for purlins, lintels, frames and machine bases. They are not interchangeable.
Can you supply structural steel for a full shed?
Yes — beams, channels, angles, purlins, roofing sheet and the fasteners on one order. Send the fabricator's cutting list and we will quote the whole lot.
