Gangsteel – Leading Mill-Direct Supplier of S355ML Weight & Density EN 10025-4 Steel Plates
Gangsteel supplies S355ML EN 10025-4 steel plates with verified density and weight data for accurate structural design and logistics. As a thermomechanically rolled (TMCP) fine-grain structural steel, S355ML has a standard density of 7.85 g/cm³ (7850 kg/m³), enabling precise mass calculations for offshore, bridge, and heavy fabrication projects. We maintain over 5,000 tons in stock, thicknesses 6–200 mm, widths 1500–4200 mm, lengths up to 18 meters, with full EN 10204-3.1/3.2 certification and third-party inspection (DNV, ABS, LR, BV, CCS, KR, TÜV, SGS).
All plates include Z25/Z35 through-thickness options and 100% UT EN 10160 S2/E2 testing. Fast global delivery and full processing available.

S355ML under EN 10025-4:2004 (2019) is a TMCP weldable fine-grain structural steel with a consistent density of 7.85 g/cm³ (7850 kg/m³ or 490 lb/ft³). This value is standard for low-alloy steels and remains stable across temperature ranges used in structural applications.
Weight calculation formula: Weight (kg) = Length (m) × Width (m) × Thickness (m) × 7850
Example:
S355ML’s density, combined with its 355 MPa yield strength and –50 °C toughness, allows 15–20% weight reduction compared to S355J2 while maintaining the same material volume efficiency.

S355ML EN 10025-4 steel has a density of 7.85 g/cm³, enabling accurate weight calculations: Weight (kg) = L × W × T × 7850. This consistent density, paired with 355 MPa yield and –50 °C toughness, supports 15–20% weight reduction vs S355J2. Gangsteel stocks all thicknesses with verified data sheets.
Q1: What is the exact density of S355ML?
A: 7.85 g/cm³ (7850 kg/m³), verified on every heat per ISO 1183-1. Use this for all weight and buoyancy calculations.
Q2: How much does a 12m x 2.5m x 50mm S355ML plate weigh?
A: 12 × 2.5 × 0.05 × 7850 = 11,775 kg (25,960 lb).
Q3: Is density the same as S355J2?
A: Yes – both are 7.85 g/cm³. The weight saving comes from using thinner S355ML due to better thick-plate properties.
Q4: Do you provide weight calculators?
A: Yes – contact us for our Excel weight tool or online calculator.
Q5: Delivery time to the U.S.?
A: 7–12 days to major ports (Houston, LA, NY).
