S280GD Galvanized Steel Coil | 1.0244
- John
Galvanized steel is an essential material in contemporary building and production, recognized for its excellent resistance to corrosion. S280GD galvanized steel, in particular, stands out as a versatile material, offering a balance of strength and durability.
At SteelPro Group, we provide high-quality S280GD galvanized steel coils and sheets to meet the demanding requirements of construction frameworks, automotive components, and household appliances. This article will introduce you to the characteristics, applications, and technical specifications of S280GD, so you can make informed decisions about your next project.
S280GD Hot-dip Galvanized Steel Description
S280GD is a strong, low-alloy structural steel that’s widely used in construction and manufacturing. With a minimum yield strength of 280 MPa, it’s tough enough for demanding structural tasks. The hot-dip zinc coating provides superior protection against corrosion, guaranteeing extended durability. Thanks to this blend of strength and protection, the S280GD is perfect for structural frames, roofing systems, and other heavy-duty applications.
The name S280GD is derived from European standard EN 10346 and stands for:
- S: Structural grade steel.
- 280: Minimum yield strength of 280 MPa.
- GD: Suitable for continuous hot-dip galvanization.
SteelPro Group offers S280GD galvanized steel in various forms, including coils, sheets, and strips. Each product supports a range of metal coatings such as Z275, Z100, and AZ150, meeting rigorous quality standards.

S280GD Steel Applications
- Construction: Structural frameworks, roofing systems, wall panels, steel decking, and facade elements.
- Automotive: Underbody components, reinforcements, brackets, door panels, and exhaust system parts.
- Appliances: Washing machine drums, dryer housings, refrigerator panels, HVAC enclosures, and water heater tanks.
- Agricultural Equipment: Silos, storage bins, farming machinery components, and greenhouse structures.
S280GD Steel Properties
High Corrosion Resistance:
The hot-dip galvanizing process creates a durable zinc coating that effectively prevents rust, ensuring the steel can withstand prolonged exposure to humidity and wet conditions.
Enhanced Structural Stability:
S280GD maintains its mechanical performance under both static and dynamic loads, making it reliable for load-bearing frameworks and dynamic structures like bridges and cranes.
Excellent Formability:
This steel grade can be easily shaped into complex components such as roofing profiles, wall cladding, and structural panels without cracking or losing surface quality.
Strong Coating Adhesion:
The zinc coating is tightly bonded to the steel surface, ensuring long-term corrosion protection even after cutting, bending, or forming.
Outstanding Weather Resistance:
S280GD resists environmental wear in harsh climates, including prolonged exposure to rain, snow, and temperature fluctuations, ensuring a consistent performance over time.
High Heat Reflectivity and Insulation Capability:
Its surface can reflect a significant amount of radiant heat, helping to maintain stable interior temperatures in structures and making it an effective material for energy-efficient roofing or insulation.
