PZ Sheet Piles Specification
Nature of PZ Serie Sheet Pile: Chinese national standard, equivalent to or referenced by EN 10248 (European standard for hot-rolled steel sheet piles).
Scope of Application: PZ sheet pile specification include the folowing content, the classification, model, dimensions, section properties, weight, tolerances, technical requirements, inspection methods, inspection rules, and delivery requirements for hot-rolled z type steel sheet piles.
Explanation of index numbers:
- W-Effective width
- H-Effective height
- T-Web thickness
- S-flange thickness.
PZ-type steel sheet pile section model naming method: PZWx (section modulus) / 100 (rounded) – W (effective width)
Example: PZ12-770
PZ Sheet Pile Introduction
PZ sheet piles, also known as z profiles, z type sheet pile, is a hot rolled steel sheet pile product with improved bending strength, with the 2 larssen interlocks on the sheet pile ends, which can be connected to form a continuous sheet pile wall for water and earth retaining.

PZ Sheet Pile Dimension and Section Modulus
GB/T 20933 PZ-type steel sheet piles are standardized in China. They feature a high section modulus, easy construction, and excellent interchangeability. They are widely used in hydraulic engineering, foundation pits, revetments, and permanent structures. Equivalent to the commonly used PZ/PZC series internationally, they fully meet national standards and can be mass-produced by steel mills, making them suitable for bidding and standardized design， Here are the dimensions and sectional modulus tables of 700 mm 750 mm/770 mm wide PZ sheet piles: .
