Galvanized steel sheet

Galvanized steel sheet is a metal material that is plated with a zinc layer on the surface of ordinary steel sheet. Made by hot-dip galvanizing or electrogalvanizing process, it has excellent anti-rust and corrosion resistance. Widely used in construction, automobiles, home appliances and other fields, such as roofs, body parts, electrical enclosures, etc., it is an important basic material for modern industry.

Physical Properties:

Appearance:

The surface is plated with a layer of zinc, usually silver white, with good appearance decorative coating toughness **: The coating has strong toughness and can withstand mechanical damage during transportation and use.

Processing Properties :

For example, electrogalvanized steel sheet has good processing properties.

Dimensions:

Common thicknesses are 0.44~ 1mm and other series, and the format size is usually 1800mm × 900mm.

chemical properties:

Anti-rust ability:

The chemical properties of zinc are more active than that of iron, and the galvanized layer formed on the surface of the steel plate can be used as a protective layer. When the coating is damaged, zinc will preferentially oxidize over iron, thus protecting the steel plate from corrosion.

Anti-oxidation ability:

The surface has strong anti-oxidation ability, which can strengthen the corrosion resistance of parts.

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.
