10 Fatal Mistakes Overseas Buyers Make When Ordering Heavy Steel Structures(Section 6-10)
6. Choose factory without EXC3/EXC4 CE execution certification
EU, UK heavy industrial steel projects require high-grade EXC3/EXC4 CE certificate. Suppliers only with EXC2 certification cannot clear customs, goods detained or pay huge fines.

7. Unreasonable foundation matching for heavy concentrated load
Heavy equipment and crane bring large concentrated ground pressure. General light steel foundation design cannot bear load, leading to foundation settlement and frame tilt after production start.

8. Save cost by reducing bolt grade to 8.8 grade
All heavy steel key connection nodes must adopt 10.9 high-strength friction bolts. 8.8 bolts insufficient shear resistance under dynamic vibration, easy to slip and lose tightening force.

9. No vibration isolation design for stamping, forging equipment
Strong mechanical resonance will accelerate steel frame aging. Suppliers ignore vibration damping measures, shorten whole building service life by half.

10. Lack complete after-sales technical support for heavy equipment installation
Heavy steel frame needs precise coordinate matching with large production machines. Factories without overseas engineer guidance lead to equipment installation deviation and rework cost.
