A practical guide to structural steel — the sections, plate and grades used in building and infrastructure, and how to buy export-direct.
Home › Guides › The Complete Structural Steel Guide
Key takeaways
- S355 is the modern default structural grade (less steel for the same load).
- Sections: H-beam, angle, channel, hollow section, plus plate and pipe.
- Specify grade + standard (EN 10025 / ASTM) and a 3.1 MTC.
- Weight is fixed by section — use the weight charts to estimate tonnage.
Structural steel grades
S235, S275 and S355 (EN 10025); A36/A992 (ASTM). Full detail: structural steel grades explained.
Beams and sections
H-beams & I-beams, angles, channels and hollow sections. Sizing: H-beam sizes, angle sizes, channel sizes, and SHS vs RHS.
Plate and pipe
Steel plate (3–100 mm) and steel pipe / seamless pipe. See plate weight chart, pipe sizes and pipe vs hollow section.
Estimating tonnage
Section weight is fixed — use the steel weight chart to convert lengths/areas to tonnage. Steel plate = 7.85 kg/m² per mm.
Accessories & connections
Anchor bolts, shear studs, grating and guardrail complete the structural package.
Buying structural steel in bulk
Specify profile, grade and standard, request a 3.1 MTC, and agree Incoterms. We export structural steel to markets worldwide.
Frequently asked questions
What is the best structural steel grade?
S355 is the common modern default — higher strength means less steel for the same load, often more economical overall.
Do you supply cut-to-length beams?
Yes — cut, drilled or fabricated to your GA drawings.
What plate thickness do you stock?
3–100 mm in S235–S355, A36 and boiler grades, mill-certified.
