Sections, Bars & Fabrication Steel
Structural Steel
Structural steel buying depends on section geometry as much as material grade. Flowline presents bars, box sections, angles and related forms in a way that lets fabricators start with the section, then confirm dimensions, thickness, length, grade and quantity.

Technical guide
Start with the section geometry, then the grade.
Section type, dimensions, thickness and length define most structural buying decisions. Grade, quantity and fabrication drawings complete the requirement.
Flowline’s catalogue includes weight-per-metre tables for square bars, box sections and angles. On the website, those product forms sit beside engineering calculators and clear enquiry guidance so a fabricator can move from section selection to a usable purchase description.
Provide the section type or designation, key dimensions, wall or flange thickness where relevant, grade, length and quantity. A fabrication drawing is especially useful when the section description is non-standard or part of a fabricated assembly.

Within Structural Steel
Structural forms organised by how they are specified.
Bars, hollow sections, angles, channels and beams use different dimensional descriptions. Choose the section form first, then confirm its designation or key dimensions.
