⚙️ Manufacturing Technique
Manufacturing Technique Diagram
A steel structure building is a prefabricated system built with bolted connections, consisting of three core parts:
  • 1. Primary frame (columns & beams)
    Made of H-section steel or square tubes (for columns) and standard H-beams (for beams), tailored to your building’s load and span requirements.
  • 2. Secondary framing (purlin, bracing)
    C/Z purlins and bracing systems that reinforce the structure and hold the roof/wall panels securely.
  • 3. Cladding & accessories
    Roof/wall sheeting or sandwich panels (EPS/glass wool/PU) + rolling doors, windows, vents, and other functional components.

❓ Frequently Asked Questions

Q1: What are the primary structural components of a steel structure building?

A1: The primary structure consists of columns and beams made of welded H-section steel or square tubes, connected securely to the foundation using pre-embedded anchor bolts and bolted together with high-strength bolts.

Q2: What is the difference between Glass Wool and Rock Wool sandwich panels?

A2: Glass wool sandwich panels are lightweight and offer excellent thermal insulation and sound absorption. Rock wool sandwich panels provide superior Class A fire resistance and high load endurance, making them optimal for fire-sensitive industrial settings.

Q3: How is the steel structure protected from environmental corrosion?

A3: All steel frame components undergo advanced surface treatments, including spraying anti-rust paint or hot-dip galvanization, to provide excellent long-term resistance against rust, moisture, and corrosion.

Q4: Are the wall and roof panel options customizable?

A4: Yes, we provide colored corrugated steel sheets, glass wool sandwich panels, and rock wool sandwich panels in customizable colors, thicknesses, and materials depending on your specific thermal insulation and design needs.

Q5: How are these prefabricated steel structures assembled on-site?

A5: Prefabricated steel structures are designed as a bolted system. The components are pre-engineered to specifications and shipped to the site where they are assembled using high-strength bolted connections and embedded foundation bolts, minimizing installation time.
