Manufacturing Technique

A steel structure building is a prefabricated system built with bolted connections, consisting of three core parts:

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.
Secondary framing (purlin, bracing)
C/Z purlins and bracing systems that reinforce the structure and hold the roof/wall panels securely.
Cladding & accessories
Roof/wall sheeting or sandwich panels (EPS/glass wool/PU) + rolling doors, windows, vents, and other functional components.

Frequently Asked Questions

What are the main components of a steel structure building?

A steel structure building consists of three main parts: the primary frame (H-section steel columns & beams), the secondary framing (C/Z purlins and bracing), and the cladding systems (roof/wall sandwich panels or corrugated steel sheets) along with standard accessories.

How are columns and beams connected in the structure?

The columns and beams are securely connected using high-strength bolts. The column bases are anchored to the concrete foundation using pre-embedded anchor bolts to ensure structural stability.

What cladding materials do you offer for walls and roofs?

We offer various options including colored corrugated steel sheets, glass wool sandwich panels, and rock wool sandwich panels. These options provide varying levels of thermal insulation, sound absorption, and fire resistance.

What are the advantages of using rock wool sandwich panels?

Rock wool sandwich panels provide Class A fireproof performance, excellent thermal and sound insulation, and moisture resistance, making them ideal for fire-sensitive industrial plants.

How is the steel structure protected against rust and corrosion?

All steel frames undergo surface treatments such as spray anti-rust paint or hot-dip galvanization to ensure long-term durability and resistance against corrosion.

Can the steel buildings be customized to specific sizes?

Yes, columns, beams, cladding colors, and panel materials can all be customized and tailored according to your specific building load, span, and functional requirements.
