SF626 Double-Seal PVC Sheet Pile for Cutoff and Seepage Control

Q: What is the reference MOQ for PVC profiles?

The current company reference MOQ for profiles is 10,000 m. Specification, colour, tooling, packaging and the confirmed order can change the final MOQ.

SF626 is a shallow double-seal PVC sheet pile with a 626 mm effective width, 650 mm listed section width, 92 mm depth and 6 mm wall thickness. It is positioned for cutoff, seepage-control and water-management barriers where joint sealing and installation quality are central to performance.

SF626 is positioned as a double-seal cutoff and seepage-control profile. Dimensions, section properties and design-reference values are provided below as searchable HTML rather than image-only content.

Property	Option 1
Catalog-listed overall section width	650 mm
Section depth	92 mm
Wall thickness	6 mm
Moment of inertia per pile	478 cm⁴
Section modulus per pile	103 cm³
Ultimate moment per pile	6 kN·m
Ultimate shear per pile	38 kN
Catalog design reference moment per pile	4 kN·m
Catalog design reference shear per pile	26 kN
Effective interlocked width	0.626 m
Flexural strength	≥65 MPa
Tensile strength	≥45 MPa
Shear strength	≥26 MPa
Elastic modulus	≥2600 MPa

The catalog labels 650 mm as section width and 0.626 m as effective width. The model designation follows the effective width.

Engineering notice: Catalog values support model comparison and preliminary discussion. Final wall capacity, pile length, embedment, bracing, interlock treatment and installation method require project-specific structural and geotechnical design.

Application focus

Where This Model Fits

Cutoff walls

The double-seal concept is intended for continuous barriers; project leakage criteria and joint details still require confirmation.

Agricultural drainage

The shallow 92 mm profile can be evaluated for farmland tailwater channels and inlet pretreatment barriers where design loads are suitable.

Water-management separation

Use for hydraulic separation concepts after confirming water head, ground conditions and installation tolerances.

System design

PVC Sheet Pile System Advantages

No steel rusting

Rigid PVC does not oxidize like carbon steel in wet or marine exposure. Chemical compatibility, UV exposure and temperature still need project review.

Continuous interlocking wall

Interlocking profiles create a continuous barrier. Watertight performance depends on the selected joint, sealing detail, installation quality and leakage criterion.

Efficient handling

PVC profiles are comparatively light to handle. Actual lifting, driving equipment and productivity depend on pile length, soil, access and guide-frame design.

Method selection

Installation Planning by Pile and Ground Condition

Short piles

The catalog recommends excavator pressing or a small vibratory hammer for rapid installation where ground conditions permit.

Medium or long piles

Use a pneumatic hammer or light vibrator after drivability, alignment and profile protection are considered.

More than 4 m

Coordinate a custom steel driving guide or sleeve that fits the profile. Control verticality and interlock engagement throughout installation.

Field applications

Application Reference Gallery

These photographs show genuine sheet pile construction environments relevant to the product category. They illustrate application context rather than claiming that every photographed project used this exact model; final profile selection requires project data and engineering review.

Urban Riverbank Revetment

A clean shoreline edge for water management and landscape integration.

Riverbank Sheet Pile Installation

Driven wall installation beside an existing waterway where access and alignment control matter.

Landscape Shoreline Protection

Bank stabilization where corrosion resistance and a neat finished line are valued.

FAQ

SF626 Technical FAQ

What project information is required to select SF626?

Provide wall length, pile length, exposed and retained heights, design water levels, soil profile, groundwater, surcharge, target leakage control, design life, installation access and applicable code. Final selection requires project-specific structural and geotechnical review.

Are the catalog design moment and shear values final project capacities for SF626?

No. They are catalog design reference values per pile for model comparison. The project engineer must verify load combinations, soil-structure interaction, embedment, bracing, joints, durability and installation effects.

Can SF626 be installed with an excavator?

The catalog recommends excavator pressing or a small vibratory hammer for short piles. Medium or long piles and difficult soils may require a pneumatic hammer or light vibrator. Piles longer than 4 m or adverse conditions may need a custom steel driving guide.

What is the reference MOQ for PVC profiles?

The current company reference MOQ for profiles is 1,000 m. Specification, colour, tooling, packaging and the confirmed order can change the final MOQ.

Automatic Production lines:

The high-speed production line guarantees a monthly output around 25,000 meters,it means we only need 10 days to complete a 40HQ container production.

Store:

Use pallets to keep the sheet pile from being under heavy pressure when stacked, and use rain cloth to prevent extreme weather from affecting the sheet pile.

Loading:

The use of tools such as forklifts makes the

container loading process convenient and efficient
