S4 x 7.7 x 10 ft Galvanized Steel I Beam
S4 x 7.7 x 10 ft Galvanized Steel I Beam
The S4 x 7.7 x 10 ft galvanized steel I beam is a high-strength structural steel section widely used in construction, industrial frameworks, and infrastructure engineering. Manufactured in compliance with ASTM A992 and ASTM A123 standards, this beam provides excellent load-bearing capacity, dimensional stability, and long-term corrosion resistance due to its hot-dip galvanized coating.
It is designed for demanding environments such as bridges, warehouses, factories, and outdoor structural systems, where durability and safety are critical
Key Features
Section Profile
The "S" shape of this I-beam provides an optimized strength-to-weight ratio, with the flanges offering excellent resistance to bending moments and the web providing strong vertical support.
Load-Bearing Capacity
Engineered to handle substantial weight loads while maintaining structural integrity, making it suitable for beams, columns, and framing in various construction projects.
Corrosion Resistance
The steel is hot-dip galvanized with a protective zinc coating that provides superior resistance against rust and corrosion, extending the product's lifespan even in harsh environments.
Long-Lasting Protection
The galvanized finish ensures the steel maintains its strength and appearance over time, reducing maintenance costs and increasing durability.
