Pannelli di rivestimento in acciaio Corten

Corten steel siding panels are essential materials in container manufacturing and architectural cladding. They are often called “ship plates” because containers must withstand marine transportation conditions similar to ship structures.

Categoria: Acciaio Corten

Descrizione

Corten steel siding panels are widely used in contenitori di spedizione, industrial buildings, and architectural exterior walls. These panels are commonly manufactured from acciaio resistente agli agenti atmosferici, which develops a protective rust layer when exposed to outdoor environments. Because of its durability and corrosion resistance, Corten steel has become one of the most important materials for container wall panels and exterior cladding systems.

Why Container Panels Are Also Called “Ship Plates”

Corrugated Corten steel panels used in containers are sometimes referred to as “ship plates” O “marine plates.” This name comes from their similar structural design and corrosion resistance requirements compared with steel plates used in marine environments.

There are several reasons for this terminology:

Marine Transportation Environment
Shipping containers are transported by sea for long periods. The steel used for container panels must withstand salt air, umidità, and temperature changes, similar to steel used in ship structures.
High Structural Strength Requirements
Container wall panels must support stacking loads, transportation stress, and impact forces, which is comparable to the structural demands placed on ship hull plates.
Corrugated Structural Design
Both container panels and some marine structural plates use reinforced structures to increase rigidity and load capacity.

Because of these similarities, container wall panels made from weathering steel are often informally called “container ship plates” nelle applicazioni industriali.

Common Corten Steel Grades for Container Panels

Weathering steel used for container siding panels typically includes several international grades.

Standard	Grado	Applicazione tipica
ASTM	Corten A	Architectural siding and light structural panels
ASTM	Corten B	Structural panels and container walls
IN	S355J2W	Structural weathering steel components
LUI	SPA-H	Outdoor structures and container components
GB	Q355NH	Container plates and architectural panels

These grades contain alloying elements that improve resistenza alla corrosione atmosferica.

Mechanical and Chemical Characteristics of Corten Steel

Corten steel is a acciaio strutturale ad alta resistenza a bassa lega designed to form a stable protective oxide layer during outdoor exposure.

Proprietà	Typical Characteristics
Main Alloy Elements	Rame (Cu), Cromo (Cr), Nichel (In), Fosforo (P)
Forza di snervamento	Approximately 345–355 MPa depending on grade
Resistenza alla corrosione	Forms protective rust layer that slows further corrosion
Forza strutturale	Suitable for structural panels and container walls
Surface Appearance	Natural reddish-brown weathered finish

IL protective oxide layer formed on Corten steel acts as a barrier that reduces corrosion penetration and helps extend the service life of the material.

Structure of Corten Steel Container Panels

Corten steel siding panels for containers typically use a corrugated profile to improve mechanical performance.

Structural Feature	Funzione
Corrugated Profile	Increases stiffness and impact resistance
Reinforced Edges	Improves welding and assembly strength
Standardized Panel Sizes	Allows efficient container manufacturing
Weathering Surface	Reduces need for heavy protective coatings
