DX51D Z80 0.3mm*900mm JIS G3312 Pre-painted Galvanized Steel Coil For Construction

PPGI stands for Pre-Painted Galvanized Iron, also known as Pre-Painted Galvanized Steel. It is a type of coated steel product that has undergone a pre-painting process to apply a protective and decorative coating.

PPGI starts with a base metal, which is typically galvanized steel or Galvalume steel. Galvanized steel is carbon steel that has been coated with a layer of zinc through a hot-dip galvanizing process, while Galvalume steel is coated with a combination of zinc and aluminum.

PPGI features a multi-layer coating system applied to the base metal. The coating system typically consists of a pretreatment layer, primer layer, and topcoat layer(s). Each layer serves a specific purpose, such as enhancing adhesion, providing corrosion resistance, and delivering color and aesthetic properties.

DX51D is a designation for a specific grade of galvanized steel. It refers to a hot-dip galvanized steel with a minimum yield strength of 270 MPa (megapascals). This grade is widely used in various industries and applications due to its good formability, corrosion resistance, and durability.

JIS G3312 is a Japanese industrial standard that specifies requirements for prepainted hot-dip zinc-coated steel sheets and coils. It outlines the technical specifications for the base metal, coating materials, coating weight, mechanical properties, dimensions, and other relevant parameters.

This indicates that the steel coil has undergone a pre-painting process to apply a protective and decorative coating. The coil is typically made of galvanized steel (DX51D in this case) and is coated with a layer of paint on both sides.

Mechanical Properties

Application

1. PPGI is widely used in the construction industry for roofing, wall cladding, and structural components. Its aesthetic appeal, durability, and corrosion resistance make it a popular choice for residential, commercial, and industrial buildings.

2. PPGI is employed in the automotive sector for various applications, including body panels, trim parts, and underbody components. The coating on PPGI provides a decorative and protective layer, enhancing the appearance and durability of automotive parts.

3. PPGI is commonly used in the manufacturing of signboards, billboards, and other advertising displays. The vibrant colors and weather resistance of PPGI make it suitable for outdoor applications, ensuring long-lasting and visually appealing signage.

4. PPGI is used in the construction of agricultural buildings, barns, and sheds. The coated steel offers durability and resistance to harsh environmental conditions, ensuring the longevity of farm structures.

Charactristic

1. PPGI is coated with a layer of zinc or a combination of zinc and other protective coatings, providing excellent corrosion resistance. This coating acts as a barrier between the steel substrate and the environment, protecting it from rust and corrosion.

2. PPGI is available in a wide range of colors, finishes, and patterns, making it a versatile material for architectural and design applications. The coating on PPGI allows for attractive and customizable aesthetics, enhancing the visual appeal of structures and products.

3. PPGI is known for its durability and long lifespan. The galvanized or Galvalume steel substrate, combined with the protective coating, provides resistance against wear, impact, and weathering, ensuring the material's longevity.

4. PPGI is highly formable and can be easily shaped and formed into various profiles, panels, and components. It can undergo processes such as bending, roll forming, and stamping without cracking or delamination, making it suitable for different manufacturing and construction applications.

FAQ

Q1: What is PPGI?

A1: PPGI stands for Pre-Painted Galvanized Iron. It refers to galvanized steel that has been coated with a layer of paint or other protective coatings to enhance its appearance and provide additional protection against corrosion.

Q2: What is the difference between PPGI and galvanized steel?

A2: The main difference is that PPGI has an additional coating of paint or other protective coatings, while galvanized steel is coated with a layer of zinc. PPGI offers enhanced aesthetic appeal and additional corrosion resistance compared to plain galvanized steel.

Q3: What are the benefits of using PPGI?

A3: Some benefits of using PPGI include excellent corrosion resistance, attractive aesthetics with a wide range of colors and finishes, durability, formability, easy maintenance, and weather resistance. PPGI also provides additional protection to the underlying steel substrate.
