GNEE Achieves EN 10346 Certification For S550GD Galvanized Steel Plate

 

Looking for certified S550GD galvanized steel plate suppliers in China? You've come to the right place. As a direct factory with 20 years of structural steel experience, GNEE Steel is proud to announce full EN 10346 certification for our S550GD galvanized steel plates, confirming compliance with strict European quality standards. This certification ensures our products meet the highest requirements for global markets.

 

Galvanized steel certification is critical for ensuring material quality and performance consistency. While many suppliers offer S550GD steel, EN 10346 certification provides independent verification that S550GD products meet exacting standards for chemical composition, mechanical properties, and coating quality-essential for critical applications.

 

Galvanized steel plates

 

 

GNEE Steel's S550GD galvanized steel plates have been fully certified to EN 10346:2015, the European standard for continuously hot-dip coated steel flat products. The certification covers:

 

Certification Aspect	Specification	Testing Method
Product Grade	S550GD+Z	EN 10346 Clause 5
Chemical Composition	Meets EN 10346 requirements	EN ISO 10714
Mechanical Properties	Yield ≥550MPa, Tensile 600-730MPa	EN ISO 6892-1
Zinc Coating Mass	Z60-Z275 g/m²	EN ISO 2178
Coating Adhesion	180° bend without peeling	EN 10346 Clause 9.2
Surface Quality	Class A (no defects)	EN 10346 Clause 8

 

The certification was awarded after a rigorous audit by SGS, one of the world's leading inspection, verification, testing, and certification companies. The audit included on-site inspection of our production facilities, quality control processes, and product testing.

 

Our EN 10346-certified S550GD galvanized steel plates meet the following technical specifications:

 

Property	Certified Value	Tolerance
Yield Strength (Rp0.2)	550-590 MPa	±10 MPa
Tensile Strength (Rm)	600-690 MPa	±20 MPa
Elongation (A80mm)	14-18%	±1%
Thickness	0.3-6.0 mm	±0.05 mm (t≤1.0mm)
Width	600-1800 mm	±2 mm
Zinc Coating (Z180)	180 g/m²	±10%
Flatness	≤ 5 mm/m	-

 

The chemical composition, verified through independent testing, is:

Carbon (C): 0.09%

Manganese (Mn): 1.65%

Silicon (Si): 0.32%

Phosphorus (P): 0.022%

Sulfur (S): 0.018%

Aluminum (Al): 0.035%

These precise specifications ensure consistent performance across every S550GD galvanized steel plate we produce.

To maintain EN 10346 certification, GNEE Steel has implemented strict quality control processes for S550GD galvanized steel plate production:

 

• Raw Material Inspection: All incoming steel coils undergo chemical analysis and mechanical testing before production.
• Process Control: Critical production parameters (temperature, speed, coating thickness) are continuously monitored and recorded.
• Product Testing: Every production batch undergoes:

Tensile and yield strength testing

Elongation testing

Coating thickness measurement

Bend testing for coating adhesion

Surface quality inspection

• Documentation: Comprehensive batch records are maintained, including test results and production parameters, for at least 10 years.
• Regular Audits: We undergo annual surveillance audits by SGS to ensure continued compliance with EN 10346 requirements.

These processes ensure that every S550GD galvanized steel plate meets the certified specifications, providing consistent quality for our customers.

 

 

While EN 10346 is a European standard, our certified S550GD galvanized steel plates are accepted in markets worldwide. The standard is recognized as a benchmark for quality in many countries, including:

All European Union member states

United Kingdom

Australia and New Zealand (through mutual recognition agreements)

Middle Eastern countries

Southeast Asian nations

South American markets

This global acceptance makes our certified S550GD galvanized steel plates a versatile choice for international projects.
