Z Type Steel Sheet Pile Corrosion prevention solution
Americas: HDG (ASTM A123, zinc coating thickness ≥85μm) + optional 3PE coating, marked "Environmentally friendly RoHS compliant ".
Southeast Asia: The hot-dip galvanizing (zinc layer >100μm) combined with the epoxy coal tar coating has a better corrosion performance, the salt spray test failures were always 0 at 5,000 hours, is the best use for tropical marine atmosphere.
Z Type Steel Sheet Pile Locking
Design: Detail of z-shape interlock, permeability ≤1×10⁻⁷cm/s.
America: Complies with the provisions of ASTM D5887, the standard test method for water penetration through foundation and retaining walls.
Southeast Asia: Superior resistance to high ground water and flood-seepage in tropical and monsoonal areas.
Z Type Steel Sheet Pile Production Process
Steel Selection:
Select the quality grade of structural steel based on some mechanical property demands.
Heating:
Heat billets/slabs to ~1,200°C for malleability.
Hot Rolling:
