S235 from the shelves
We're not crazy!
Why use lower steelsgrades as the prices
are similar
Target groups
• Steelsuppliers
• Teachers
• Structural Engineers
What are the drivers
• Cultural change in the use of steel
• Focus on the use of the steels S355 and S460
• Steel grade S235/S275 eliminate from the market
• Cost reduction
• Material reduction
• Sustainabilty
Arguments
• S235 / S460 are ordinary steels.
• high-strength steels are S690 to S1100.
• Other material composition and welding instructions.
• S235, S275, S355 and S460 have the exact same
alloy composition, only the rolling and cooling are
different. Therefore, the cost per tonne is almost
equal.
Arguments
• When using steel grade S460 vs. S235 and S355,
the cost of the entire steel structure bearing by:
• less consumption of material steel
• Less weld volumes
• lighter assembly
• lighter steel transportation
• crane deployment and support structures
• lighter foundation
• less burden on the environment
• upcycling and reuse profiles.
Arguments
Steel is a modern material that
develops
Arguments
Steel grades Costs Strength Weight Tracebility Stiffness Weldability
S235 100 100 100 not 100 good
S275 101 120 85 must 100 good
S355 102 150 70 must 100 good
S460 102 200 50 must 100 good
It is to good to be true
Arguments
The majority of steel structures
• columns (pressure bars)
• beams (beams in bending
• truss (tension and compression members)
Variant compared with those in S235 S460: weight reduction 30 to 45%
Variant compared with those in S355 S460: weight reduction 15 to 20%

High strength steel: 51% less
Optimise embodied energy
Conclusions
1. Cheaper, more durable and also more slender steel
structures can: Use standard S355 and S460 as possible.
2. Message to Designers: replace now S235 and S275 to
S355 and S460.
3. Introduce steel S355 as the new standard, is the
intermediate step S460 as the future standard.
4. The structural engineer is the decisive factor.
5. In bridge design S355 and S460 are already standard
steels.
6. More knowledge, more applications in S460, a product that
is competitive with concrete.
