Installation
- Easy installation.
- The J-Type Anchor Bolts (bolts connecting fender anchor plates to the quay surface) can be pre-embedded during concrete pouring or post-installed using chemical anchors such as epoxy or Sika.
- Positioning of bolts is supported by templates to ensure accuracy and compliance with port technical safety standards.
- Anchor plates are easily installed with cranes or support vessels, using standard construction tools.
Quality of Anchor Bolt Accessories
- Anchor bolt accessories are certified according to international standards: PIANC, BV, or third-party organizations such as TT3 (Vietnam), SGS, etc.
- With a service life of up to 50–100 years (depending on port operating conditions), the product guarantees energy absorption and reaction force performance over time.
- Warranty: 3–5 years (depending on port design requirements).
