What are the common grades available?

We offer PSB500/630, PSB830/1030, PSB930/1080, PSB950/1050, PSB1080/1230, and PSB1200/1330 grades, with diameters from 15mm to 75mm.

Can you customize nuts and couplers?

Yes, we provide custom hex nuts, flange nuts, locking nuts, and couplers in various materials including carbon steel, copper, and aluminum.

What is the difference between bonded and unbonded PC strand?

Bonded strands are grouted into ducts, creating a permanent bond with concrete. Unbonded strands are coated with grease and plastic sheathing, allowing independent movement and easier installation.
