Steel section sizes
Steel Section Sizes and Structural Steel Section Finder
Find structural steel cross sections by designation, family, size, mass, dimensions, moments of inertia, section modulus, standards, and regional availability signals using I beam, H beam, universal beam, channel, angle, bar, hollow section, plate, sheet pile, and purlin tables.
Use this structural steel section finder to search beam, column, channel, angle, hollow section, plate, sheet pile, bar, and purlin sizes with dimensions, mass, section properties, standards notes, and regional availability signals. It is intended for discovery, comparison, and preliminary engineering conversations before final design or procurement checks.
Common engineering uses
Common engineering uses
- Find I beam, H beam, universal beam, universal column, wide flange, channel, angle, CHS, RHS, SHS, plate, bar, and purlin sizes.
- Compare dimensions, weight, area, inertia, radius of gyration, section modulus, material notes, and common standards.
- Move from broad searches such as steel section sizes to focused regional searches such as Indian, European, UK, Australian, JIS, metric, or imperial steel sections.
Outputs to review
Outputs to review
- Filterable steel section tables with designations, dimensions, weight or mass, and section properties.
- Intent pages for common search families such as I beam sizes, H beam sizes, channel sizes, RHS sizes, and steel plate weight tables.
- Availability guidance that separates market signals from live stock or final supplier commitments.
How to use this tool
How to use this tool
- Search a designation such as IPE 300, HE 200 B, UB 610 x 229, RHS 200x100, 50 x 50 x 6 angle, C20024, or 10mm plate.
- Filter by beams, channels, angles, hollow sections, plates, sheet piles, or purlins.
- Review dimensions, mass, moment of inertia, section modulus, material grade notes, governing standards, and regional availability signals.
- Verify selected sections against current supplier data, project specifications, and mill certificates before procurement or final design.
How to use the result
Search by designation, family, region, or common query phrase, then compare the section properties against the governing design standard and project requirements. Treat the table as a discovery and preliminary-check tool. Final design and procurement still need current supplier data, mill certificates, project specifications, and qualified structural review.
Assumptions, limitations, and formulas
Assumptions
Section rows are treated as engineering reference data, not a substitute for project specifications.
Family sizes and properties should be verified against the governing project standard before final design.
Material grade notes summarize common standards and do not replace mill certificates or purchase specifications.
Limitations
Some families do not yet include every possible market size or regional designation.
Regional availability guidance is a market signal based on public range data, not a live warehouse inventory feed.
Critical values must be verified against the governing standard and current supplier documents.
Final structural design must follow applicable design codes, load cases, connection checks, and qualified engineering review.
Formula notes
Common notation includes D and B in mm, mass in kg/m, area in cm2, Ix/Iy in cm4, rx/ry in cm, and Zx/Zy in cm3.
Ix and Iy are second moments of area; Zx and Zy are elastic section moduli unless a property label states otherwise.
Common questions
What steel section families are covered?
The finder covers common beams, columns, channels, angles, circular hollow sections, rectangular hollow sections, square hollow sections, plates, bars, sheet piles, C-purlins, and Z-purlins where data is available.
Can I use these steel section sizes for final design?
Use the data for discovery and preliminary comparison only. Final structural design must follow the governing design code, current supplier data, material grade requirements, connection checks, and qualified engineering review.
Does regional availability mean a section is in stock?
No. Regional availability is a market signal based on public ranges and catalogue coverage. It is not a live warehouse inventory feed and should be verified with the supplier before procurement.
