Products Description
Steel sheet piles are interlocking structural steel profiles widely used for earth retention, water barrier, and foundation support in civil and marine engineering. We provide two mainstream types: U-Type Steel Sheet Piles and Z-Type Steel Sheet Piles, including hot-rolled and cold-formed production processes. Both types feature precise interlocking joints, high structural rigidity, excellent water tightness, and reusable performance, meeting international construction standards for temporary and permanent engineering projects.
Our sheet piles are fully compliant with EN, GB, JIS, and ASTM standards, with complete custom specifications and stable export quality, serving global construction markets including Europe, Southeast Asia, the Middle East, and Africa.

FAQ
Q1: What is the difference between hot-rolled and cold-formed sheet piles?
Hot-rolled sheet piles have higher overall rigidity, better structural stability and stronger bearing capacity, suitable for heavy-duty and permanent projects. Cold-formed sheet piles feature lower cost, flexible size customization and light weight, ideal for temporary and light-load engineering projects.
Q2: Which type should I choose, U-type or Z-type?
U-type sheet piles are preferred for conventional, shallow, and temporary projects with cost priority. Z-type sheet piles are more suitable for deep foundation, high-load, marine and permanent projects due to higher section modulus and bending resistance.
Q3: Can you customize non-standard sizes and lengths?
Yes. We support full customization of length (6-24m), thickness, width and surface treatment. We can produce non-standard profiles according to customer drawings and project requirements.
Q4: What steel grades are most recommended for export?
For European markets: S355GP/S355JR; For Southeast Asian markets: SY295/SS400/Q345B; For American markets: A690/A572 Gr.50; For general global projects: Q235B/Q355B with cost performance advantage.
Q5: What is your delivery time and packaging method?
Stock products can be delivered within 7-10 days; customized products take 15-25 days. Standard export packaging: bundled with steel strips, anti-rust painting, waterproof wrapping, suitable for sea transportation and long-distance logistics.
Q6: Are your sheet piles reusable?
Yes. Our high-quality hot-rolled sheet piles have intact interlock joints and stable structural performance, which can be extracted and reused for multiple times, greatly reducing project construction costs.
Q7: What quality certifications do you have?
Our products comply with EN 10248, GB/T 29737, JIS A 5528 and ASTM standards, with ISO 9001 quality certification, third-party inspection reports (SGS/BV) available upon request.
