Source Steel

Contact our Singapore trading desk for volume-based contract pricing and global delivery schedules.

We primarily source 3SP/5SP billets and Grade 60 rebar. For HRC and plates, we provide ASTM A36 and S235/S355JR grades. Custom metallurgical requirements can be fulfilled upon request.

Yes. Depending on the volume, we offer both containerized shipping and break-bulk vessel chartering for large-scale infrastructure projects across Asia and Africa.

While steel is priced based on market indices (S&P Global/Platts), we source from reputable global refineries and LME-registered mills to ensure absolute structural integrity.

Our standard trade contracts allow for a weight tolerance of +/- 5% to 10%, which is the industry standard for bulk structural steel shipments.
