Product Description
Steel Structure Frame Prefabricated Building

Prefabricated steel structure building is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building. A steel structure is a metal structure made of structural steel members that are connected to each other to carry loads and provide complete rigidity.

🏗️
High Strength & Light Weight

Steel has a high modulus of elasticity, making it easier to transport and install, perfectly suitable for large spans and high-rise structures.

🛡️
High Reliability

Uniform internal structure with good seismic performance. The actual working performance conforms closely to calculation theory.

⏱️
Fast Installation

Mechanized manufacture provides high precision and production efficiency, resulting in quick on-site assembly.

♻️
Eco-Friendly

Minimal construction waste during demolition; steel is 100% recyclable, supporting green building standards.

Frequently Asked Questions
What is the expected lifespan of this steel structure?
The building is designed for long-term durability with a warranty and service life ranging from 50 to 70 years.
Is the steel structure fire-resistant?
While steel maintains properties below 150°C, it requires insulation or refractory materials for higher fire resistance levels in specific building types.
Can the design be customized for my specific site?
Yes, all structures are customized. We can design based on your live load requirements, wind speed, snow load, and seismic data.
How is the steel protected against corrosion?
We use two layers of anti-rust painting or galvanization. For offshore or moist environments, special protections like zinc block anodes can be used.
What information is needed for a design proposal?
Please provide the roof live load, wind speed, local snow load, earthquake parameters, and dimensions for doors/windows.
Is this building type environmentally friendly?
Yes, it is a low-carbon, green construction method. Steel components are recyclable and generate almost no construction waste.
