Looking for reliable galvanized steel plate suppliers for your construction projects? You've come to the right place. As a direct factory with over 15 years of steel production experience, GNEE Steel provides durable, EN-standard galvanized steel plates at competitive factory prices. In this guide, we'll detail the types, specifications, and application advantages of our galvanized steel plates to help you optimize your construction materials selection.
Galvanized steel plates are steel sheets coated with a zinc layer through hot-dip or electro-galvanizing processes. This coating forms a protective barrier against corrosion, extending the steel's service life by 5-10 times compared to uncoated steel.
Common grades of galvanized steel plates include S320GD, S280GD, and DX51D, each designed for specific applications-from light structural parts to heavy-load-bearing components in construction.

Specifications and Sizes of GNEE Steel's Galvanized Steel Plates
GNEE Steel offers galvanized steel plates in a wide range of specifications to meet diverse construction needs. Our standard product sizes cover most common construction requirements, and we also provide customized cutting services.
The following table lists our regular galvanized steel plate specifications:
| Thickness Range | Width Range | Length Range | Coating Weight (Each Side) | Application Scenario |
|---|---|---|---|---|
| 0.5-2.0mm | 1000-1250mm | 2000-4000mm | 60-100g/m² | Roof panels, wall cladding |
| 2.0-5.0mm | 1250-1500mm | 3000-6000mm | 80-120g/m² | Floor joists, purlins |
| 5.0-12.0mm | 1500-2000mm | 4000-8000mm | 100-150g/m² | Steel beams, support structures |
All our galvanized steel plates have strict dimensional tolerances, with thickness deviation within ±0.05mm and flatness error less than 2mm/m-ensuring easy installation and precise fitting in construction projects.
Mechanical Properties of GNEE Steel's Galvanized Steel Plates
The mechanical properties of galvanized steel plates directly affect the safety and stability of construction structures. GNEE Steel's products undergo rigorous testing to meet international standards.
The table below shows the typical mechanical properties of our popular galvanized steel plate grades:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Bending Performance (180°) |
|---|---|---|---|---|
| DX51D | ≥235 | 315-500 | ≥28 | Pass (r=0.5t) |
| S280GD | ≥280 | 370-510 | ≥22 | Pass (r=1t) |
| S320GD | ≥320 | 370-500 | ≥18 | Pass (r=1.5t) |
These properties ensure our galvanized steel plates can withstand wind loads, seismic forces, and other external pressures in construction. We provide mill test certificates (MTC) for each batch to verify mechanical performance.
Application Advantages of Galvanized Steel Plates in Construction
Using GNEE Steel's galvanized steel plates in construction offers multiple advantages:
- Superior corrosion resistance: The zinc coating prevents steel from rusting in humid, rainy, or coastal environments-critical for outdoor construction components like roof panels and exterior walls.
- Lightweight yet strong: Compared to concrete or wood, galvanized steel plates have a higher strength-to-weight ratio, reducing structural load while ensuring stability.
- Fast installation: Pre-cut and pre-drilled galvanized steel plates (available upon request) speed up on-site assembly, shortening construction cycles by 20-30%.
- Low maintenance cost: With a service life of 20-30 years, our galvanized steel plates require minimal maintenance, saving long-term repair and replacement expenses.
- Eco-friendly: Galvanized steel plates are 100% recyclable, aligning with green building standards and reducing environmental impact.
