PZ 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: The hot-dip galvanizing (zinc ≥100μm) with the epoxy coal tar coating provides excellent corrosion protection, the salt spray test failures have always been 0 at 5,000 hours, suitable for tropical marine environments.
PZ 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
PZ 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.
PZ Type Steel Sheet Pile Main Application
Retaining Walls - Proven soil support for earth and foundation work.
Cofferdams - Retaining walls that facilitate the management of water flow in a work area.
Port & Harbor Projects – Suitable for quay walls, docks, and marine applications.
Flood Control & Streambank Stability – Strengthens banks and levees with fiber reinforcement and erosion control.
Why Choose Z Type Steel Sheet Piles
1.With equal section modulus, in kgf/m2, Z type sheet piling is always lighter than the U type sheet piling.
2.Since the width is larger, the number of sheets needed is less, the cost of piling work or armouring work or so on can be saved, and this is good for watertight.
3.Be used as an infill pile with steel pipes and H beams that are commonly employed to reach very high modulus.
