Standard Sizes and Gauges for Corrugated Galvanized Steel Sheets
Selecting the right corrugated galvanized steel sheets is crucial for the success of any construction project. Understanding the standard sizes and gauges available ensures optimal performance, cost-effectiveness, and compliance with industry standards. As a leading supplier in the steel industry, Ruixiang Steel Group provides comprehensive guidance on navigating these specifications for your specific application needs.
Standard Dimension Ranges
Corrugated galvanized steel sheets are typically available in several dimension ranges to accommodate various construction requirements:

Thickness (Gauge)
The thickness of corrugated galvanized steel sheets generally ranges from 0.12mm to 1.2mm . Specific thickness options include:

Light-gauge sheets: 0.12mm to 0.29mm 

Medium-gauge sheets: 0.30mm to 0.59mm 

Heavy-gauge sheets: 0.60mm to 1.2mm 

Width and Length
Standard widths typically fall between 600mm to 1250mm , while lengths generally range from 1400mm to 3660mm . Some suppliers also offer sheets in specific imperial measurements such as 10, 18, and 20 feet .

Key Specifications and Coatings
Beyond basic dimensions, several other factors contribute to the performance and suitability of corrugated galvanized steel sheets:

Zinc Coating : Zinc coating weights typically range from Z30 to Z275 (30-275g/m²) . A higher coating weight generally provides better corrosion resistance.

Material Grades : Common grades include DX51D , SGCC, and CGCC . These grades comply with international standards such as AISI, ASTM, BS, DIN, GB, and JIS .

Applications and Selection Guidance
Corrugated galvanized steel sheets are widely used in industrial and civil buildings . Typical applications include:

Roofing and wall systems 

Interior and exterior wall decorations 

Factories, warehouses, and agricultural buildings 

When selecting materials, consider these factors:

Environmental conditions that may impact corrosion resistance needs

Structural requirements that determine the necessary thickness and strength

Local building codes and compliance requirements

Project lifespan expectations and maintenance considerations

Quality Assurance and Compliance
Reputable suppliers like Ruixiang Steel Group ensure product quality through:

Certification with ISO9001 and other relevant standards 

Third-party inspection services such as SGS 

Strict tolerance controls, typically around ±1% 

Key Takeaway
Understanding the standard sizes and specifications of corrugated galvanized steel sheets enables better decision-making for your construction projects. By considering thickness, coating weight, and material grade in relation to your specific application requirements, you can select the optimal product for durability, performance, and value.
