Welcome to StructuralSteel.ai
The intelligent reference for structural steel
StructuralSteel.ai is a data platform for structural steel: a searchable database of every standard section, verified property tables, worldwide standards guides and an AI assistant that helps you identify, compare and specify the right steel for the job.
Whether you are checking a section against your calculations, comparing international equivalents, or working out what a beam should cost before you commit, everything here is built to get you from question to answer without the usual friction.
How it works
From question to specification, in three moves.
1. Search or ask
Browse the structural steel database and filter over 540 sections by type, depth, weight and grade — or simply ask the AI assistant in plain language. Every listing carries full dimensional and structural property data, so you can confirm the section works before you go further.
2. Understand the detail
Dig into the reference library for grades, section properties, cost drivers and worldwide standards equivalents, or run the calculators for weight, span and cost answers grounded in the same verified data.
3. Specify with confidence
Take the data into your own calculations and drawings — and when you are ready to buy, request a market-indexed quotation for certified steel fabricated to BS EN 1090 EXC 3, with full mill traceability. The research tools are free whether you order or not.
What we offer
One platform,
four strengths.
01
Section Database
Every standard European and international section in one searchable database — universal beams, columns, hollow sections, channels, angles and flats — with full dimensional and structural property data.
- 540+ sections with verified data
- Filter by size, weight and grade
- Full property tables
- Worldwide equivalents
02
AI Assistant
Ask questions in plain language and get answers grounded in the same verified data — section selection, weights, spans, grades, costs and standards, with links to the relevant tables and guides.
- Plain-language section search
- Answers from verified data
- Span, grade and cost guidance
- Points you to the right table
03
Reference Library
In-depth guides on steel grades, section properties, cost drivers and design standards — including worldwide equivalents — written for engineers, buyers and anyone specifying structural steel.
- Grade and property explainers
- Cost and pricing guides
- Worldwide standards coverage
- Updated as standards change
04
Specification Tools
Calculators and comparison tools that turn raw section data into practical answers — weight, cost per tonne, load tables and side-by-side section comparison.
- Beam calculators
- Weight and cost tools
- Section comparison
- Exportable property data
Our Approach
Steel knowledge, minus the friction.
Clarity over complexity
- Structural steel information has traditionally lived in scattered tables, paywalled standards and phone calls. We put it in plain view — section data, standards guidance and pricing logic in one searchable place.
- Every page of this platform exists to answer a real question an engineer, buyer or contractor actually asks.
- If you can describe the problem, you can find the section — without the runaround.
Data you can build on
- Our database is built from verified section property tables, not scraped approximations — so the numbers you design against are the numbers the steel is rolled to.
- Guides are written against published standards: BS EN 10025, BS EN 1090, Eurocode 3 and their international equivalents.
- When standards change, the data changes with them.
Intelligence, not guesswork
- The AI assistant does not invent answers — it reasons over the same verified tables and guides you can read yourself, and shows its working.
- Ask 'what beam for a 5 metre span?' and get a reasoned shortlist, the assumptions behind it, and the data to check it.
- You stay the engineer of record; the platform does the digging.
Built for the whole team
- Estimators get transparent cost intelligence. Engineers get verified section data. Buyers get plain-language guides before they spend anything.
- One reference platform, one consistent dataset, from first sketch to final specification.
- Whether it is one beam or a full frame, the same tools apply.
Verified & Certified
Standards behind
every number.
The platform is built on published standards — BS EN 10025, BS EN 1090, Eurocode 3 and their international equivalents — and our underlying quality systems are independently audited under ISO 9001. When you order through the platform, that rigour carries through: fabrication to BS EN 1090 EXC 3 with full mill traceability as standard.
- BS EN 1090 EXC 3
- BS EN 9606-1 Coded Welders
- ISO 9001 Quality
- CE Marking
- Full Mill Traceability
- Digital Certificate Portal
Who it's for
Built for
your side of the drawing.
Engineers & designers
Verified section data at your fingertips
Full geometric and structural properties for every standard section, filterable by the values that matter to your calculations — depth, weight, moment of inertia, section modulus. Written against Eurocode 3 and BS EN standards, with worldwide equivalents.
- 540+ sections with property tables
- Search by structural values
- Grades to BS EN 10025
- Worldwide standard equivalents
