Structural W sections with wide flanges and an I-shaped cross-section
Commercial overview. SUALSA supplies wide flange W structural steel sections (American Parallel Flange Profiles) according to its official technical data sheet. The table includes 79 metric W designations (height x flange width x mass, for example W 310x165x38.7) from W 100x100x19.3 to W 610x325x195, with dimensions, area, mass and geometric properties verified by SUALSA.
Product Description
The W section is a structural steel profile with an I-shaped cross-section and wide flanges, internationally known as a Wide Flange Beam. Its metric designation combines nominal height, flange width and nominal mass, all as given in the official SUALSA data sheet. For example, W 310x165x38.7 identifies a section with a nominal height of 310 mm, a flange width of 165 mm and an approximate nominal mass of 38.7 kg/m.

Technical use: these values come from the official SUALSA technical data sheet. For structural design projects, confirm the current edition of the documentation with SUALSA.
Steel Grades, Standards and Documentation
The technical data sheet does not clearly state a steel grade, product standard or delivery condition applicable to every section. These requirements must be stated in the enquiry and confirmed before supply. Where the project requires an inspection certificate, traceability, testing or special requirements, they must be expressly defined in the order.
Frequently Asked Questions
What is a W section?
It is a wide flange structural section with an I-shaped cross-section, used as a beam or column.
What does W 310x165x38.7 mean?
It identifies a section with a nominal height of 310 mm, a flange width of 165 mm and a nominal mass of 38.7 kg/m.
What range does the table cover?
From W 100x100x19.3 to W 610x325x195, in the official SUALSA data sheet.
