DX51D Z150 Galvanized Steel Coil

DX51D+Z150 galvanized steel coil is one of the best-selling products of Wanzhi Steel, as well as one of the most commonly used materials. DX51D+Z is a steel code according to European standards (EN10327), which refers to flat hot-dipped galvanized steel for common uses. Due to its low carbon content, DX51D+Z material has high elongation but average ductility and stamping ability. Besides, its zinc coating thickness (double sides) is 150 g/m², which provides great corrosion resistance. Wanzhi Steel specializes in the production and processing of DX51D+150 galvanized coils. The thickness and width can be customized. We also provide strip perforation machining. If you are interested, please contact us.

Features

1. Outstanding Corrosion Resistance

“Z150” represents a double-sided zinc coating of 150 grams per square meter. The uniform zinc layer thickness and strong adhesion effectively isolate air and moisture from the steel substrate, significantly improving corrosion resistance.

2. Excellent Processing Compatibility

“Dx51D” is a low-carbon galvanized steel for cold forming. Its excellent plasticity and toughness allow for easy bending, stamping, and shearing operations without zinc detachment or cracking.

3. Stable Basic Performance and Versatility

The steel coil’s stable chemical composition and consistent tensile and yield strength ensure consistent quality across batches. Furthermore, its smooth surface is suitable for subsequent surface treatments such as spraying and printing.

Uses

1. Construction

It can be processed into wall panels, sandwich panels, corrugated boards, or used to make ventilation ducts, chimneys, and drain pipes. It can also be further coated into colored steel sheets for decorative roofing and fence panels.

2. Home Appliances and Electronics

This material can be used as the base material for the housing or casing of almost all household appliances, such as refrigerators, microwave ovens, air conditioner outdoor units, and air purifiers.

3. Transportation and Logistics

It can be used for subway, truck, trailer, and car compartment panels, warehouse shelves, and container bases, offering resistance to friction, impact, and corrosion.

4. Daily Use

Such as hardware, security doors, guardrails, clothes drying racks, etc., or metal furniture frames, benches, and stationery.

What Is DX51D + Z?

DX51D+Z is a code of continuously hot-dipped galvanized flat steel products. In DX51D, the first “D” indicates low carbon steel for cold forming, and “X” means that the rolling state of the substrate is not specified. If the second letter is “C”, it means the substrate is cold-rolled steel; while if the second letter is “D”, it means that the substrate is hot-rolled steel.

“51” is the serial number of the steel grade. The number can be 52, 53, 54, etc. The bigger the number, the better the deep drawing performance of the material. Below are the chemical compositions of DX51D.

Chemical Compositions	C%	Si%	Mn%	P%	P%	Ti%
DX51D	≥0.12	≥0.5	≥0.6	≥0.1	≥0.045	≥0.30

Uses of different steel grades

Below are the codes for different steel grades and applications. Compared with DX53/54D+Z, DX51D+Z is cheaper. You can choose suitable material according to its use.

DX51D	Bending and forming quality (commercial use)
DX52D	Drawing use
DX53D	Deep drawing use
DX54D/DX55D	Extra deep drawing use
DX56D	Ultra-deep drawing use
DX57D	Super deep drawing use

And the second letter “D” means hot dip galvanizing. If the letter is “E”, it stands for electro-galvanizing.

“Z” and number show the zinc coating thickness. For example, Z150 means the pure zinc coating on both sides is 150 grams per square meter. Z275 means the zinc coating is 275 g/m², which is about 0.9 ounces per square foot. That’s why Z275 is equivalent to G90. Except for pure zinc coating, “AZ” is used to show the galvalume coating thickness. For example, AZ150 means the base metal is coated with 1.5 ounces of aluminum zinc coating per square foot (double sides). Wanzhi Steel offers AZ30 to AZ150 galvalume steel.
