ASTM A572 Grade 50	345	450–620	20
ASTM A690	345	470–620	20
ASTM A588	345	470–630	20

NOTE:

1.All three grades have high yield strength (≥345 MPa) suitable for heavy structural applications.

2.ASTM A690 is optimized for marine and port environments.

3.ASTM A588 offers natural corrosion resistance due to its weathering properties.

4.Elongation around 20% ensures ductility for construction and installation.

ASTM Z Type Steel Sheet Pile Corrosion prevention solution

Americas: HDG (according to ASTM A123, zinc thickness ≥ 85μm) + optional 3PE coating, marked "Environmentally friendly RoHS compliant".

Southeast Asia: Adopting a combined process of hot dip galvanizing (zinc layer thickness ≥ 100μm) and epoxy coal tar coating, its core advantage lies in no rusting even after 5,000 hours of salt spray testing, making it suitable for tropical marine climate environments.

ASTM Z Type Steel Sheet Pile Locking

Design: Z-shape interlock, permeability ≤1×10⁻⁷cm/s
America: Meets the requirements of ASTM D5887, the standard test method for penetration of water through foundation and retaining walls.
Southeast Asia: High groundwater and flood-seepage resistance for tropical and monsoonal regions

ASTM Z Type Steel Sheet Pile Production Process

Steel Selection:

Choose high-quality structural steel according to certain mechanical property requirements.

Heating:

Heat billets/slabs to ~1,200°C for malleability.

Hot Rolling:

Shape steel into Z-profile with rolling mills.

Cooling:

Cool at Cool or tap water spray dote until the target water content was reached.

Straightening & Cutting:

Maintain the accuracy of the tolerance while cutting the material to standard or custom lengths.

Quality Inspection:

Perform dimensional, mechanical and visual inspections.

Surface Treatment (Optional):

If required, apply paint, galvanize or protect from rust.

Packaging & Shipping:

Pack, protect, and pick up for shipping.
