Real-World Project Experience
Case Study 1: Siberian Railway Station
Challenge:
I beams must withstand -45°C without brittle fracture.
Solution:
Supplied S355J2 grade with Charpy V-notch impact testing at -40°C (min 27J) and customized 12m lengths.
Result:
Zero structural failures in 3 years; praised for exceptional low-temperature performance.
Case Study 2: Dubai Industrial Warehouse
Challenge:
Project delayed due to non-standard 11.3m beam requirement.
Solution:
Fast-track custom cutting service delivered 500+ pre-painted beams in 10 days.
Result:
Saved client $85,000 in delay penalties; secured 4 repeat orders.
