The weight per meter of steel sheet piles varies significantly depending on their cross-sectional shape (Z-type, U-type, or flat type), height, width, and thickness.

Generally, the weight of a single standard steel sheet pile ranges from approximately 20 kg/m to over 120 kg/m.

The following guide can help you determine the required weight:

1. Common standard sections (approximate weights)

The most common standard sections globally are Z-types and U-types (such as those produced by ArcelorMittal). The weights listed below are for a single pile:

1) Light-duty (typically 8mm to 10mm thick)

PU 12 / AZ 12: approx. 20 – 24 kg/m

PU 18 / AZ 13: approx. 30 – 32 kg/m

2) Medium-duty (typically 10mm to 12.4mm thick)

PU 22: approx. 38.7 kg/m

AZ 18-700: approx. 42.6 kg/m

AZ 26-700: approx. 61.5 kg/m

JIS SP-IV (400x125): approx. 38.0 kg/m

3) Heavy-duty (typically 12.4mm to over 15mm thick)

PU 32: approx. 56.5 kg/m

AZ 36-700: approx. 85.2 kg/m

JIS SP-IV (400x170): approx. 60.0 kg/m

JIS SP-IV (500x200): approx. 105.0 kg/m

2. How to calculate the weight yourself

If you have specific cross-section specifications or are using flat steel plates, you can calculate the weight using the density of steel (7,850 kg/m³).

1) For flat steel plates: Weight (kg/m) = Thickness (mm) × Width (m) × 7.85. Example: A flat plate 12 mm thick and 1 m wide has a weight of 12 × 1 × 7.85 = 94.2 kg/m.

2) For formed steel sheet piles (Z-type or U-type): Due to their curved shape and interlocking structure, their weight is slightly higher than that of a flat plate of the same thickness. If the cross-sectional area from the technical specifications is known: Weight (kg/m) = Cross-sectional area (cm²) × 0.785.

3. Estimating total project tonnage (weight per square meter)

When placing orders for construction projects, engineers typically calculate the weight per square meter of the finished wall to estimate the total tonnage.

Wall weight per square meter = Weight of a single pile (kg/m) ÷ Effective width of the pile (m).

Example: The AZ 26-700 steel sheet pile weighs 61.5 kg/m and has an effective width of 0.7 m. The weight of the wall is 61.5 ÷ 0.7 = 87.8 kg/m².

Do you have a specific profile designation (e.g., AZ 26, PU 22, SP-IV) or specific dimensions (height, width, and thickness)? If you can provide this information, I can calculate the precise weight per meter for you.
