Corten Corrugated Metal Siding

Corten corrugated metal siding refers to weathering steel corrugated sheets used in container systems, modular buildings, 산업 구조. In applications such as shipping containers or container-style architecture, corten steel is commonly divided into 측면 패널, 지붕 패널, and bottom structures, each designed for different load conditions and environmental exposure.

Although all parts are made from corten steel, 그들의 두께, profile strength, and functional requirements are not the same.

1. 측면 패널 (Side Corrugated Corten Steel Sheets)

Side panels are the most visible parts of a container or building structure.

주요 특징

• Medium-strength corrugated profile
• Balanced between strength and appearance
• Designed for vertical load distribution
• Moderate thickness compared to bottom structure

일반적인 두께

• 1.6 mm - 2.0 mm (선적 컨테이너)
• 1.5 mm - 3.0 mm (architectural use)

Main Functions

• Provide structural enclosure
• Resist lateral wind pressure
• Support stacking load transfer
• Serve as external protective shell

주요 특징

Side panels focus on overall structural stability and corrosion resistance, while also maintaining a uniform exterior appearance.

2. 지붕 패널 (Top Corrugated Corten Steel Sheets)

Roof panels are exposed to the most direct environmental conditions.

주요 특징

• Usually thinner than side and bottom panels
• Designed for drainage and weather resistance
• Corrugation optimized for rain runoff
• Light to medium structural strength

일반적인 두께

• 1.2 mm - 1.6 mm (컨테이너)
• 0.8 mm - 1.5 mm (architectural roofing)

Main Functions

• Protect internal structure from rain and sunlight
• Provide water drainage via corrugation design
• Resist wind uplift forces
• Maintain lightweight structure

주요 특징

Roof panels prioritize weather resistance and weight reduction, rather than heavy load bearing.

3. Bottom Panels / 바닥 구조 (Heavy-Duty Base Steel)

The bottom section is the most critical load-bearing area in container systems.

주요 특징

• Thickest corten steel section
• Often reinforced with structural beams
• Designed for high impact and load resistance
• May be combined with wooden or composite flooring

일반적인 두께

• 2.0 mm - 3.0 mm (steel base sheet)
• Additional structural support beams underneath

Main Functions

• Support total cargo or structural weight
• Resist forklift impact and mechanical stress
• Provide long-term structural integrity
• Connect with chassis or foundation systems

주요 특징

Bottom panels require the highest strength and durability, as they carry all static and dynamic loads.

Key Differences in Design Purpose

1. Load Distribution

• Bottom panels carry maximum structural load
• Side panels distribute lateral forces
• Roof panels handle 환경 노출

2. Thickness and Strength Design

Each section uses different thickness to balance:

• Weight efficiency
• Structural safety
• 재료비

3. Corrosion Exposure Conditions

• Roof panels: highest exposure to rain and UV
• Side panels: 적당한 노출
• Bottom panels: lower direct exposure but higher mechanical stress

Why Corten Steel Is Suitable for All Three Parts

Corten steel is ideal for corrugated siding systems because:

• It forms a protective rust layer outdoors
• It has high mechanical strength
• It performs well under alternating wet/dry conditions
• It reduces long-term maintenance needs

This allows the same material system to be used across side, roof, and bottom structures with different thickness designs.
