DX51D SGCC Color Coated Corrugated Galvanized Steel Roofing Sheets 0.2–1.0mm for Roof Wall Panels
Product Overview
DX51D SGCC color coated corrugated galvanized steel roofing sheets are engineered for roofing, wall cladding, industrial buildings, warehouses, agricultural facilities, and prefabricated structures. Manufactured from premium galvanized (GI) or galvalume (GL) steel coils, these sheets deliver exceptional corrosion resistance, structural strength, weather durability, and aesthetic appeal.
Available in diverse corrugation profiles, thicknesses, widths, lengths, and RAL colors, our roofing sheets comply with ASTM A792, EN 10143, JIS G3302, and other international standards. Custom production and processing services are available for construction projects worldwide.
Why Choose Color Coated Corrugated Galvanized Roofing Sheets?
Roofing materials must endure prolonged exposure to sunlight, rain, wind, and temperature fluctuations while preserving structural integrity and appearance.
How Color Coated Corrugated Steel Roofing Sheets Protect Buildings
The steel substrate is first coated with zinc or aluminum-zinc alloy to provide sacrificial corrosion protection. A chemical pretreatment layer enhances coating adhesion before primer and topcoat paint are applied.
The coated steel is then roll-formed into corrugated profiles, increasing structural rigidity while maintaining lightweight design. This multi-layer protection system effectively resists:
Rainwater corrosion
UV exposure
Oxidation
Temperature fluctuations
Mechanical deformation during installation
The corrugated profile also improves water drainage and load-bearing performance.
Selecting the Right Corrugated Roofing Sheet
Choose the Appropriate Steel Grade
DX51D / SGCC - General construction and roofing
DX52D - Better formability for complex profiles
S350GD / G550 - Higher yield strength for long-span roofing systems
Galvanized (GI): Suitable for general outdoor applications
Galvalume (GL): Better corrosion and heat resistance, especially in coastal or high-temperature environments
Select Paint System
Polyester (PE): Standard architectural applications
SMP: Improved weather resistance
PVDF: Superior UV and corrosion resistance for demanding environments
Consider Local Climate
For coastal, humid, or industrial environments, selecting higher zinc coating weights and premium paint systems enhances long-term durability.
Frequently Asked Questions
What is the difference between galvanized and galvalume roofing sheets?
Galvanized roofing sheets are coated with zinc, while galvalume sheets use an aluminum-zinc alloy coating. Galvalume generally offers better corrosion resistance and heat reflectivity, especially in coastal or high-temperature environments.
What thickness is recommended for roofing projects?
For residential roofing, 0.3-0.5 mm is commonly used. Commercial and industrial buildings often require 0.5-0.8 mm or thicker, depending on structural design and wind load requirements.
Can the roofing sheets be customized?
Yes. We provide customized thickness, length, profile, RAL color, zinc coating, logo, packaging, and OEM production based on project specifications.
What standards do your roofing sheets comply with?
Our products are manufactured according to ASTM A792, EN 10143, JIS G3302, and other international standards, with Mill Test Certificates (MTC) and third-party inspections available upon request.
Are these roofing sheets suitable for coastal areas?
Yes. For marine or coastal environments, we recommend galvalume substrates with higher coating weights and PVDF paint systems to provide enhanced corrosion resistance and longer service life.
