DX51D Z80 & Z100 Galvanized Steel Coil: The Reliable Choice for Global Construction
In the competitive world of steel procurement, finding the perfect balance between cost-efficiency and durability is the key to a successful project. For most construction, roofing, and light industrial applications, the DX51D + Z80/Z100 series is the global industry standard.
As a leading manufacturer based in the renowned steel hub of Liaocheng, China, we specialize in exporting high-quality Hot-Dipped Galvanized Steel (GI) Coils that meet strict international standards. Whether you are a wholesaler or a large-scale contractor, our DX51D series provides the reliability your clients demand.
What Does DX51D + Z80/Z100 Actually Mean?
Understanding the technical designation is the first step in ensuring you have the right material for your market:
DX51D Grade:This is the European standard (EN 10346). The "D" stands for flat products for cold forming, and "51" indicates the steel grade for bending and profiling. It is highly versatile and easy to process into roofing sheets or C-purlins.
Z80 Coating:This indicates a total zinc coating weight of 80 grams per square meter(both sides). It is the "sweet spot" for many developing markets, offering good rust protection at an economical price.
Z100 Coating:With 100 grams of zinc per square meter, this grade offers enhanced corrosion resistance for outdoor structures and environments with moderate humidity.
Why Choose Our DX51D Series?
Buying steel is about more than just the price per ton. It is about the quality that prevents complaints and returns. Our production lines ensure:
1. Superior Surface Quality
We offer a variety of surface finishes to suit your local market preferences:
Regular Spangle:The traditional "zinc flower" look that many markets in Africa and South America associate with high-quality galvanized steel.
Zero Spangle:A smooth, uniform matte finish that is perfect for clients who plan to paint or coat the steel later.
2. Excellent Formability
The DX51D base metal is engineered for flexibility. Our coils can be rolled, bent, and profiled into complex shapes (like corrugated roofing or air ducts) without the zinc layer cracking or peeling off.
3. Precision Thickness and Width
In the export business, "tolerance" matters. We provide precise thickness ranging from 0.12mm to 2.0mm and standard widths like 914mm, 1000mm, 1219mm, and 1250mm. You get exactly what you pay for—no thin-gauge surprises.
Applications of Z80 and Z100 Galvanized Coils
Because of their durability and cost-effectiveness, these coils are used across multiple sectors:
Roofing & Siding:The #1 use for DX51D. It is pressed into corrugated sheets for residential and industrial buildings.
HVAC Systems: Used for air ducts and ventilation units due to its rust-proof properties.
Electrical Cabinets:Providing a sturdy, corrosion-resistant housing for sensitive components.
Purlins & Studs:Essential for modern light-gauge steel framing.
