Prefabricated Multi-story Steel-frame Buildings
Heavy-duty multi-span steel structure buildings designed for earthquake and wind resistance, offering superior durability and safety for industrial applications.
Product Overview
Our multi-story steel structure factory buildings utilize a heavy-duty steel structure system fabricated using high-strength steel. Available in both light and heavy-duty configurations to meet diverse industrial requirements.
Light-Duty Steel Structures
Utilizing Q235 and Q355 series thin-walled steel with small component sections and light weight. Ideal for light industrial production scenarios with smaller loads and moderate spans, such as electronics processing and small assembly workshops.
Heavy-Duty Steel Structures
Built with Q355, Q420, and higher-strength thick plate steel, offering strong component load-bearing capacity and high rigidity. Suitable for heavy loads and large spans required in industries such as heavy machinery processing, metallurgy, and power generation.
We provide single-span, double-span, and multi-span steel structures, as well as single-story, double-story, and multi-story steel frame factory buildings. Custom designs and production are available according to your site size, production scale, process layout, and specific application needs.
Manufacturing Process
I. Preliminary Preparation and Design Refinement
- Refinement of Design Drawings
- Formulation of Processing Plan
II. Raw Material Arrival and Inspection
Raw material quality is the core guarantee of heavy steel structure safety. Strict control is maintained throughout the entire process of arrival, inspection, and storage.
III. Core Processing Stage (Factory Prefabrication)
This stage represents the core of heavy steel structure processing. All components are prefabricated in standardized factory conditions, strictly adhering to process standards:
- Steel Cutting
- Component Forming and Processing
- Welding Operations
- Post-Welding Treatment
- Corrosion and Fireproofing Treatment
- Component Identification and Numbering
