Digital ordering and Certficate registration

Goal: reduce costs in the supply chain

• Cost savings in administrative

processes

• Acceleration of internal processes

• Improving communication between

companies

• Preventing errors

Digital ordering and Certficate registration

Contains:• Messages between client and supplier

• Quotations, orders, bills of loading, certificates,

invoices

• Integration of communication with ERP systems

• Messages are automatically read and information is

presented to users

Digital ordering and Certficate registration

Benefits for the steel fabricatorBecause information from the steel trade is automatically

processed in the ERP system, you can:

– Applications Easier quotes, compare quotes, place orders and modify

– Certificates automatically attach to components

– Easy to check and process invoices

– Time saving for the buyer, planner and logistics

• Questions / discussion

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.

What can we do as IPO’s

IPO’s together give more power

We can share ideas

Steel suppliers are interested, get funding
