Corten B steel plates are roll-formed metals that develop a protective rust layer when exposed to the atmosphere. This rust coating shields the underlying steel from corrosion, giving it an advantage over conventional steel plates used in various industries. BS 4360 WR 50 C steel plates, for example, feature low phosphorus content, making them a suitable alternative to other structural steels.
1. Excellent Workability
UNI FE 510 D2K1 Corten steel plates contain alloying elements like carbon, chromium, nickel, and manganese, which enhance their formability. These plates are suitable for cold forming, hot forming, and gas cutting, allowing versatile manufacturing options.
2. High Reliability
SEW 087 WTSt 52-3 steel plates are durable, corrosion-resistant, and highly dependable. With a minimum tensile strength of 485 N/mm², they maintain shape under pressure and can be fabricated into complex forms without deforming.
3. Lightweight and Long-Lasting
EN10025-5 S235 J2W steel plates are ideal for architectural structures requiring strong yet lightweight frameworks. They resist cracking or distortion under mechanical stress, making them suitable for projects with constant load or vibration.
4. Cost-Effective
JIS G 3114 SMA 50 CP steel plates naturally develop an oxidized surface layer, which prevents further corrosion without additional painting or coatings. ASTM A 588 Grade B steel plates, being largely self-protective, reduce maintenance costs, making them economically advantageous.
5. Weather and Corrosion Resistance
NFA 35-502 E36 WB weather-resistant plates use rust as a protective shield. The patina safeguards the inner steel from environmental damage, making these plates 4–8 times more durable than regular steel.
6. High Tensile Strength
Copper is added as an alloy in ASTM A 242 Type 1 weathering steel plates. It accelerates the rust formation process and boosts tensile strength when used in sufficient quantities.
