GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Mechanical Properties
| Steel Grade | Yield Strength | Tensile Strength | Elongation | Impact Energy |
|---|---|---|---|---|
| Q235B | ≥235 MPa | 370–500 MPa | ≥26% | ≥27 J |
| Q355B | ≥355 MPa | 470–630 MPa | ≥22% | ≥27 J |
Explanation:
Yield Strength (ReH): Yield strength, the stress at which steel begins plastic deformation.
Tensile Strength (Rm): Tensile strength, the maximum stress before steel fractures.
Elongation (A%): Elongation, the percentage of material elongated before fracture, reflecting toughness.
Impact Energy (J): Impact toughness (Charpy V-notch), commonly used value at 20°C, suitable for construction environment requirements.

GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Production process
1.Raw Material Selection
High-quality carbon structural steel billets (Q235B / Q355B) are carefully selected and tested to ensure chemical composition meets GB/T 20933 standards.
2.Billet Heating
Steel billets are heated in a continuous reheating furnace to approximately 1150–1250°C, ensuring uniform temperature for optimal rolling performance.
3.Primary Rolling (Rough Rolling)
Heated billets are passed through rough rolling mills to reduce thickness and form preliminary shapes.
4.Finish Rolling
The steel is further processed through finishing mills to achieve precise dimensions, thickness, and mechanical properties required for sheet piles.
5.Profile Forming
Using specialized rolling equipment, the steel is shaped into U-type or Z-type sheet piles, ensuring accurate interlocking edges for construction use.
6.Controlled Cooling
Sheet piles undergo controlled air cooling or accelerated cooling to refine grain structure and achieve required strength and toughness.
7.Straightening & Alignment
Finished sheet piles are straightened using leveling machines to ensure dimensional accuracy and proper alignment.
8.Cutting & Length Customization
Steel sheet piles are cut to required lengths (typically 6m–18m) with optional end finishing or beveling.
GB/T 20933 Hot Rolled Q235B Q355B Steel Sheet Pile Surface
Americas:HDG as ASTM A123 (min zinc coat ≥ 85 µm); 3PE coating is optional; all finishes RoHS compliant.
Southeast Asia:The thickness of hot dip galvanized is hollyh (over 100μm), and two layers of epoxy coal tar coating are applied, it can be salt sprayed tested for 5000 hours without rust, is the best for tropical marine environment use.
