Product Description
High-Strength Heavy-Duty Steel Structure Processing
Professional manufacturer specializing in hot-dip galvanized heavy steel structures for industrial and construction applications.
Product Overview
Heavy steel structures are engineered systems designed for large loads, long spans, high-rise buildings, and extreme working conditions. These structures exceed standard industry benchmarks with superior load-bearing capacity and durability.
Industry Standards & Specifications
- H-beam column plate thickness ≥ 25mm
- Component plate thickness typically ≥ 20mm
- Single-piece weight mostly > 10 tons
- Utilizes hot-rolled H-beams and wide thick steel plates
- High-strength bolts and welded joints
- Designed to withstand dynamic loads, heavy loads, strong winds, earthquakes, and corrosive environments

Core Materials & Construction
- Steel Grade: Customizable - commonly Q355 (formerly Q345), Q390, Q420; special projects use Q460, Q690, and weathering/marine steel
- Component Types: Welded box columns, cross columns, large-section H-beams, trusses, steel column bases/supports
- Connection Methods: Factory welding + on-site high-strength bolt connection with ultrasonic (UT) and magnetic particle (MT) non-destructive testing
- Protection System: Sandblasting + zinc-rich primer + intermediate coat + topcoat; coastal/chemical zone applications include anti-corrosion coating or hot-dip galvanizing
Product Advantages
- Superior Structural Performance: High-strength steel with large-section components provides excellent load-bearing capacity, wind resistance, earthquake resistance, and structural stability
- Efficient Construction: High-precision prefabrication with on-site assembly using welding and high-strength bolts ensures short construction cycles and easy quality control
- Durable & Low Maintenance: Professional anti-corrosion and fireproofing treatments ensure long service life with minimal maintenance requirements
- Customization & Adaptability: Component specifications and processes can be customized for heavy loads, high temperatures, and corrosion resistance with flexible spatial layouts
- Economical & Eco-Friendly: Controllable construction costs with recyclable materials that generate no waste pollution, aligning with green construction principles
- Uniform Quality: Standardized industrial production ensures consistent component quality and stable material properties
Professional Services
- Design: Free design services provided
- Manufacturing: Over 20 years of experience with capability to produce wide variety of projects
- Installation: Detailed drawings provided with installation, supervision, and training services including online guidance or on-site engineer support
- Packing: Customized according to customer requirements
Manufacturing Process
As a professional steel structure manufacturer with large-scale processing facilities, we provide one-stop service from design to delivery with standardized processes and quality control.
- Cutting: High-precision automated laser cutting of beams, columns, and steel plates to exact design dimensions
- Assembly: Pre-cut steel components aligned and fitted according to engineering blueprints and specifications
- Welding: Professional welding methods creating sturdy, durable joints that enhance overall load-bearing performance
- Derusting: Sandblasting, shot blasting, or chemical cleaning to remove rust and create contaminant-free surfaces
- Surface Finishing: Spray painting or hot-dip galvanizing to form protective corrosion-resistant layers
Packaging & Shipping
Main steel frames are packed on steel pallets for optimal protection and efficient loading/unloading. This method also reduces shipping container requirements and ocean freight costs. Secondary components are packed in parcels and loaded into containers for safe, easy handling.
