FSP Sheet Pile Specification

FSP steel sheet piles, reffer to u-shaped section sheet piles originating in Japan, are a hot-rolled product developed from the Larsen-type steel sheet pile. FSP Sheet Piles are widely produced and supplied in Asian regions. Widely used for their reliable interlocking and excellent cross-sectional properties, offer section modulus ranging from 874cm3 to 3820cm3 per linear meter of wall. This sheet pile series have gradually become a standard U-type model in the Asian market.

Scope of Application: FSP 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 U type steel sheet piles.

FSP Series Sheet Pile Introduction

The FSP series includes standard models FSP-I through FSP-V and the widened types – FSP-IIIW, meeting the needs of general foundation pit support, water retaining, and earth retaining projects. Widely types fsp sheet piles are also known as the FSP-SX series, such as the FSP-III-SX and SX10, utilize higher-strength steel or optimized cross-sectional designs to provide a larger section modulus and greater bearing capacity, the SX series have the same size and section modulus value of widened series. FSP steel sheet piles are widely used in municipal engineering, port projects, bridge projects, and river management projects.
