Structural Section Optimization
Automatically find the optimal structural section according to your custom criteria against standard or custom shapes.
Standard Library
Find the optimal section against multiple standard from ASTM, ANSI and EN.
Custom Criteria
Create extensive criteria targeting geometric properties, by example, set an height limit or minimum section modulus.
Shape Solver
Solve custom criteria against the standard libraries and custom shapes to find the most efficient section.
Find the Optimal Section
nSection let you compare multiple shapes so you can choose the optimal one according to your need.
Parametric Generate custom geometries that extend far beyond standard manufacturing tables.
Standards Effortlessly toggle between Metric and Imperial units and global design codes.
Optimization Instantly identify the most efficient section based on your weight, size, and other criteria.
Beams

Developer Driven
Built for Power Users
Engineers shouldn't waste time on repetitive data entry. nSection was designed to provide a high-performance web interface for structural properties. We prioritize data accuracy, speed of retrieval, and clean exports to make your workflow frictionless.
Vast Databases
Thousands of profiles across North American and European catalogs, indexed for search.
Exact Geometry
Precise fillet radius and toe measurements included for high-fidelity detailing.
Advanced Search
Find the lightest section for a required Section Modulus or Moment of Inertia.
Frequently Asked Questions
How accurate is the property data?
All standard profile data is sourced directly from the latest AISC, ASTM, and Eurocode publications to ensure 100% engineering compliance.
Can I generate non-standard shapes?
Yes. Our parametric engine allows you to define custom depths, widths, and thicknesses for any profile type to evaluate built-up sections.
Is there a cost for the service?
nSection will offer a robust free tier for standard lookups, with a professional subscription for advanced exports and API access.
Will it support 3D model exports?
Initially, we provide 2D profile coordinates and property data. 3D DXF and IFC exports are on our development roadmap for late 2026.
Can I use this for university research?
We love supporting education. Students and researchers will have full access to our database for academic use.
Does it include stainless steel sections?
Yes, we include standard profiles for stainless steel and aluminum, categorized by their specific geometric standards.
