Details Showing

We understand that quality expectations vary across different regions. While many buyers focus primarily on pricing, we believe in offering transparent, choice-based solutions.

To meet this, we provide two distinct quality levels:

Premium Grade (for high-demand projects) – Manufactured with #45 steel using a hot-rolling process.
- D17mm tensile strength: 185–190 kN
- D20mm tensile strength: ≥200 kN
  Ideal for structural integrity and long-term durability.
Standard Grade (for cost-sensitive applications) – Produced with Q235 steel via cold-drawing.
- Tensile strength: 130–140 kN
  Suitable for general use where budget is the primary concern.

This flexible approach ensures our clients receive the right product for their specific project needs—without overpaying for unnecessary specifications.
