Color coated board

Color-coated sheet is a kind of metal composite material that applies organic coatings on the surface of steel plates. It has advantages such as bright colors, good appearance and durability, and anti-corrosion. It is often used in fields such as the exterior walls of buildings, interior decoration, and the shells of household appliances. For example, the walls of factory buildings and the side panels of refrigerators. Its performance is stable and it can adapt to different environments. It is one of the commonly used materials in modern industry and life.

Physical Properties of Color Coated Plates

1. Mechanical Properties – Strength: Color coated plates usually have a certain strength and can withstand certain loads and external forces.

Ductility: Have a certain degree of ductility, so that it is not easy to break during processing and molding. – Hardness: The surface hardness is moderate to ensure that it is not easy to be scratched during use.

2. Coating Adhesion – The adhesion between the coating and the substrate is strong and not easy to peel off.

3. Surface Flatness – The surface is flat and smooth, which is conducive to aesthetics and subsequent processing.

4. Coefficient of Thermal Expansion – There will be a certain degree of expansion when heated, which needs to be considered in the design and use.

Chemical Properties of Color Coated Plates

1. Corrosion Resistance – The coating on the surface can effectively resist the erosion of corrosive substances such as oxygen, moisture, acid rain in the atmosphere. – It also has certain tolerance to acids, alkalis, salts and other chemicals.

2. Oxidation Resistance – It is not easy to oxidize in the air, maintaining the stability and color of the surface.

3. Weather Resistance – It can withstand long-term sunlight exposure, temperature changes and climate changes to maintain stable performance.

Stringent product quality inspection

Surface quality inspection
Use the surface roughness detector to inspect the surface roughness, the adhesion and thickness of the coating (if any).
Appearance inspection
Check whether there are scratches, pits, rust spots, oxide skin and other defects on the surface of steel products.
tensile test
Determine indicators such as tensile strength, yield strength, elongation, etc., and evaluate the strength and plasticity of the steel plate.
Galvanized layer inspection
Make sure that the thickness of the galvanized layer meets the specified requirements to provide adequate corrosion protection.
Size detection
Measure the diameter, length, and thickness of steel pipes to ensure they meet specific customer requirements.
Spectral Analysis
Examining Steel Composition Through Emission Spectra Using Advanced Spectroscopic Methods and Techniques
Bending detection
Observe whether there are cracks, folds, peeling and other defects on the surface of the bent steel plate.
non-destructive testing
Used to detect internal defects in steel, such as cracks, pores, etc.

Inventory and Package

Plate package

steel plates together using steel bands and then wrapped in waterproof paper or plastic sheets to protect against moisture and corrosion

Coil package

Steel coils are wrapped in waterproof paper or plastic sheeting and sometimes further protected with metal sheet covers.

Pipe package

Pipes are usually bundled together and strapped. Ends are often capped to prevent damage and ingress of dirt,anti-corrosion measures.

Rod package

The bundles are then wrapped with waterproof material, and sometimes, anti-rust oil or coatings to prevent corrosion.
