SPA-C Corten Steel For Building Decoration

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional spa-c corten steel for building decoration manufacturers and suppliers in China. Welcome to wholesale customized spa-c corten steel for building decoration at competitive price from our factory. Good service and quality products are available.

SPA-C is formed by cold rolling on the basis of hot-rolled SPA-H, and is finished by multi-pass rolling mill to achieve:

• Improved surface accuracy: The thickness tolerance of the steel plate is controlled at ±0.05mm, and there is no oxide scale on the surface, which directly presents a metallic luster base, providing an ideal carrier for the uniform adhesion of the rust layer
• Optimized mechanical properties: Grain refinement increases the yield strength by 10%, and the cold bending performance reaches d=1.5t (t is thickness), supporting precision bending processing of R≤50mm
• Dimensional stability: Plate straightness ≤1mm/m, suitable for making large-size curtain wall panels (maximum processing width 1500mm× length 12000mm)

• Excellent weather resistance: In harsh environments such as acid rain, salt spray, and industrial pollution, the corrosion rate is only 1/10 of that of ordinary steel, and the service life is up to 30-50 years
• Strong aesthetic expression: The texture formed by natural rust changes over time, and the thickness of the rust layer can be customized (50-150μm), which is suitable for various design languages ​​such as industrial style, wabi-sabi style, and retro style
• Excellent processing performance: It can be cold-bent (bending radius ≤2t), welded (no special welding rods required), punched, and supports complex modeling processing
• Green and environmentally friendly: 100% recyclable, the production process reduces more than 90% of coating pollution, and meets the requirements of LEED and China Three-Star Green Building Certification

• 1. High-end building facade curtain wall
  Applicable scenarios: super high-rise buildings, commercial complexes, cultural landmarks

• 2. Interior decoration and art installations
  Rust screen/partition: 3mm thick SPA-C cold-rolled plate is hollowed out by laser cutting, and the surface is sealed (such as silane impregnation). No rust liquid seepage is used in an indoor environment with a humidity of ≤70%
  Ceiling and wall decoration: 5mm Thick plates are bent into wavy or zigzag shapes, and warm light lighting highlights the metal texture of the rust layer, which is suitable for cultural and creative parks and high-end clubs.

• 3. Precision landscape sculptures and installations
  Technical highlights:
  Thickness tolerance ±0.05mm ensures the accuracy of curved surface modeling, suitable for 3D printing mold molding (such as hyperbolic sculptures)
  The width of the welding heat-affected zone is ≤5mm, which can achieve millimeter-level fine welding and retain the integrity of the surface rust layer
  Typical applications: Abstract art sculptures in urban squares, iconic installations in real estate demonstration areas, such as the material comparison design of mirror stainless steel and SPA-C rust plate

• 4. Special environment high durability projects
  Coastal high salt fog environment: In areas with Cl⁻ concentration ≥1000ppm (such as Hainan and Okinawa, Japan), the corrosion resistance of SPA-C is 8 higher than that of ordinary cold-rolled steel times, it is recommended to match the edge with stainless steel edging for waterproofing
