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
1. It is applicable to bridge abutments and deep foundation pit excavation support. By relying on the strong retaining capacity of steel sheet piles, it can restrain the surrounding soil and prevent slope collapse, ensuring the safety of underground foundation construction.
2. A closed water-blocking and retaining dike structure is constructed within the foundation pit to isolate external water and soil, creating a dry and stable internal working space, facilitating on-site reinforcement of steel bars and concrete pouring, etc. of the construction.
3. It is used for coastal and wharf protection embankment construction to resist wave impact, stabilize the soil of the shoreline, and serve as a permanent or semi-permanent coastal retaining structure. It is widely applied in port and waterway projects.
4. Riverbank slope reinforcement and flood embankment construction to reduce the erosion of water flow on the riverbank, stabilize the river embankment, and play a role in flood prevention and shore protection, preventing river collapse.
Why Choose Z Type Steel Sheet Piles
1. High cross-sectional modulus, excellent bending resistance, and stronger retaining capacity at the same weight.
2. The locking mechanisms of the Z-shaped steel sheet piles are tightly interlocked, resulting in excellent water sealing performance. It can effectively block water and soil, and the support is very stable and reliable.
3. This product is manufactured using a hot-rolled integrated forming process. The material is of high quality and uniform, with high strength. It has a long service life and is relatively durable. It can also be pulled out and reused after use.
4. The Z-shaped steel sheet piles have been pre-formed. They are convenient for construction at the construction site, with fast driving and extraction speeds.
5. Complete specifications, support fixed-length processing, and are suitable for various engineering scenarios such as cofferdams, foundation pits, and port revetments.
Packaging & Shipping
1. Transport using standard containers, with Z-shaped steel sheet piles neatly stacked.
2. Securely fasten with high-strength straps to prevent displacement and damage during transportation.
3. The packing plan has been optimized to fully utilize the space of the containers and save on shipping costs.
4. Exporting the entire container, suitable for ocean shipping, ensuring the safe delivery of goods to overseas construction sites.
FAQ
Q1: Can PZ steel sheet piles be used in marine environments?
A1: Yes. The PZ series Z type steel sheet piles are suitable for marine and offshore engineering scenarios. If you need to enhance the corrosion resistance, you can be equipped with hot-dip galvanizing or epoxy coating for anti-corrosion treatment, thereby extending the service life in seawater environments.
Q2: How long is the delivery cycle?
A2: For regular products: 7-15 days for delivery;
For custom production orders: 15-30 days;
For large-scale projects: Priority production can be arranged, and urgent delivery can be negotiated.
Q3: What packaging method is used for PZ steel sheet piles?
A3: The products are packed in steel bundles. Protective end caps are added at the ends and waterproof wrapping is applied to ensure the safety of ocean export transportation and prevent damage and moisture absorption during transportation.
Q4: Is customization of length supported?
A4: Yes. According to the engineering design requirements, we can produce steel sheet piles of any custom length ranging from 6 meters to 24 meters.
Q5: Are you a manufacturer or a trader?
A5: We are an original manufacturing and export-oriented enterprise. We offer factory direct supply prices with stable supply. We provide steel components for global infrastructure projects.
Q6: Is the installation of PZ steel sheet piles difficult?
A6: The locking mechanism operates smoothly, and the pile driving construction is convenient. With the use of regular pile driving equipment, the project can be carried out. This significantly shortens the construction period of the foundation pit and cofferdam.
Q7: Can steel sheet piles be reused?
A7: The hot-rolled PZ steel sheet piles have high structural strength. After the project is completed, it can be removed and recycled, and can be reused multiple times, thereby reducing the total investment in the project.
