ขายเหล็กแผ่น Corten
Corten steel sheets for sale are commonly available in thicknesses from 0.8 มม. ถึง 6 มม, making them suitable for architectural, ตกแต่ง, and light structural applications. Thin gauges are preferred for cladding and design projects, while thicker sheets offer improved strength for outdoor industrial use. Choosing the right corten sheet thickness depends mainly on whether the application focuses on appearance, การประดิษฐ์, or structural performance.
- คำอธิบาย
Corten steel sheets for sale are usually supplied as weathering steel flat products used for architectural cladding, การออกแบบภูมิทัศน์, ตู้คอนเทนเนอร์, และงานโครงสร้าง. Compared with thicker corten plates, corten steel sheets mainly refer to thinner gauges that are easier to bend, ตัด, and weld for decorative or light structural applications.
The most common grades include ASTM A606 Type 4, มาตรฐาน ASTM A588, and equivalent weathering steel grades such as S355J2W and Q355NH. The main difference between sheet and plate is usually the ช่วงความหนา.
Standard Thickness of Corten Steel Sheets
Corten steel sheets are generally available in thin and medium gauges. For commercial supply, the most common thickness range is:
| ความหนา (มม) | ความหนา (นิ้ว) | การใช้งานทั่วไป |
|---|---|---|
| 0.8 มม | 0.031″ | แผงตกแต่ง |
| 1.0 มม | 0.039″ | งานหุ้มผนัง |
| 1.5 มม | 0.059″ | หน้าจอสวน |
| 2.0 มม | 0.079″ | ขอบภูมิทัศน์ |
| 3.0 มม | 0.118″ | Exterior panels |
| 4.0 มม | 0.157″ | Structural covering |
| 5.0 มม | 0.197″ | Container fabrication |
| 6.0 มม | 0.236″ | Heavy sheet applications |
In most markets:
- Below 6 มม is usually called corten steel sheet
- Above 6 มม is often classified as corten steel plate
This naming convention depends on suppliers and local steel standards.
Common Sheet Width and Length
Corten sheets are typically supplied in standard mill dimensions.
| ความกว้าง | ความยาว |
|---|---|
| 1000 มม | 2000 มม |
| 1219 มม | 2438 มม |
| 1250 มม | 2500 มม |
| 1500 มม | 3000 มม |
| 2000 มม | 6000 มม |
Custom cutting services are often available for laser cutting, ดัด, and fabrication according to project drawings.
Why Thickness Selection Matters
The thickness of corten steel sheets affects both appearance and service life.
Thin Sheets (0.8–2 มม)
These are mainly used for:
- Decorative facades
- Exterior wall panels
- Rusted art panels
- ขอบสวน
- Signage
Thin corten sheets develop rust quickly and are easier to shape into custom designs.
Medium Sheets (3–6 มม)
These are commonly used for:
- Structural wall cladding
- พาร์ทิชันกลางแจ้ง
- ผนังกันดิน
- Industrial enclosures
- Shipping container panels
Medium thickness provides better flatness, ความแข็งแกร่ง, and longer service life in outdoor environments.
Corten Sheet vs Corten Plate Thickness
| ประเภทสินค้า | ความหนาทั่วไป |
|---|---|
| แผ่นคอร์เทน | 0.8–6 มม |
| แผ่นคอร์เทน | 6–100 มม |
Sheet products are mainly used where flexibility and surface appearance are important, while plate products are selected for load-bearing structures.
สภาพพื้นผิว
Corten steel sheets for sale are usually supplied in three surface conditions:
- Black steel surface — original mill finish
- Pre-rusted surface — accelerated oxidation treatment
- Weathered surface — naturally exposed patina finish
Pre-rusted corten sheets are popular for projects requiring immediate decorative rust appearance without waiting for natural oxidation.
