Investors who chose World Steel
A selection of the clients who build with World Steel.
What clients say
“The warehouse constructed by World Steel is the largest in the Long Son oil refinery project, covering nearly 6 hectares. With 58,000 square meters for a single warehouse and a completion time of less than 12 months, I believe WS has done an excellent job. It is likely that the workers and colleagues at WS worked extremely hard and gave their best effort within a short period of time.”
“I recognize that World Steel has strong capabilities and high expertise in construction, which is why we chose World Steel.”
