Wanzhi-Spangles

Character interpretation

DC01: A standard grade for cold-rolled low-carbon steel sheet and strip, primarily defined by German or EU standards. It is equivalent to the cold-rolled low-carbon steel sheet and strip specified in the national standard GB/T 5213-2008.
Galvanized steel coil: A steel coil coated with zinc to prevent corrosion, which can be cut and processed as needed.

Key Features

Stable Base Material

DC01 cold-rolled low-carbon steel has low hardness and good ductility, providing an excellent foundation for processing and galvanizing.

Excellent Corrosion Resistance

The zinc layer protects the base material through a “sacrificial anode,” forming a dense protective film that slows down corrosion. Wanzhi Steel can customize the zinc layer thickness.

Outstanding Processability

Excellent cold working properties allow for easy stamping and bending, with low yield strength and high elongation, making it less susceptible to cracking during processing.

Excellent Surface Quality

After hot-dip galvanizing, the surface exhibits a spangled or uniform silver-gray color with excellent gloss, eliminating the need for additional coating. Can be used directly or for subsequent painting.

Low Cost

Lower cost than stainless steel, offering a high cost-performance ratio and flexible specifications to meet the feed requirements of different production lines, suitable for applications requiring moderate corrosion protection.

Applications

Construction

Used as a raw material for lightweight steel keels, rolling shutters, ventilation ducts, and other applications, it can withstand humid outdoor environments and meet complex design requirements.

Home Appliance Industry

As housings or internal structural components for appliances such as refrigerators, washing machines, air conditioners, and microwave ovens, its smooth surface reduces the need for painting, and its excellent formability makes it suitable for mass production.

Automotive Parts Manufacturing

Used for non-load-bearing components such as door linings and small chassis parts, its low hardness facilitates stamping, and its zinc coating protects against corrosion in humid environments, achieving a balance between performance and cost.

Daily Goods Manufacturing

Used for shelving, filing cabinets, metal boxes, and more, its flat surface enhances the appearance and quality, accommodating diverse designs while also meeting durability requirements.

Industrial Equipment

It can be used to manufacture equipment housings, guardrails, pipe supports, and more. Its corrosion resistance adapts to the complex environment of factory workshops, while offering low installation and maintenance costs.

Recommended zinc coating for different scenarios

Construction: Z180-Z275. For roofs/walls/light steel structures, high zinc coating provides long-term corrosion protection, with a lifespan of 20 years or more.
Appliance housings: Z60-Z120. Such as refrigerators/air conditioners/washing machines. Low corrosion risk in indoor environments. Appliance lifespans are typically 10-15 years.
Automotive parts: Z90-Z150. Interior trim/non-load-bearing structural parts meet the manufacturer’s 5-8 year corrosion protection requirements. This zinc coating does not interfere with resistance welding.
Cable trays/electrical cabinets: Z120-Z200. Industrial environments present a risk of electrochemical corrosion.
Agricultural equipment: Z200-Z350. For granaries/farm machinery housings exposed to corrosive media such as fertilizers and organic acids, zinc-aluminum-magnesium plating with passivation treatment can be used to further enhance corrosion resistance.
Color-coated substrate: Z60-Z100, which needs to be coated or painted later. Too thick a zinc layer can easily cause the coating to fall off, and high coating uniformity is required.

Factory Quality Inspection

To ensure that DC01 galvanized steel coils meet international quality standards, Wanzhi Steel implements the following rigorous quality inspection procedures: Checking the chemical composition of DC01 cold-rolled steel coils, zinc ingot testing, zinc layer weight, uniformity, and adhesion, and ensuring the absence of surface defects, zinc slag, and scratches. Mechanical tests include tensile testing, hardness testing, and cupping testing. Salt spray testing and damp heat testing are also performed for corrosion resistance. After assembly, dimensional and visual inspections are conducted, including thickness, width, coil weight, and the absence of zinc particles, zinc dust, roller marks, and edge burrs and cracks.
