What is steel structure?

The steel structure is a load-bearing structural system mainly composed of steel materials, which is constructed through methods such as welding and bolt connection. It is composed of core components such as steel beams, steel columns, steel trusses, and steel plates. Its cross-section forms are diverse. For example, the I-shaped steel beam can bear lateral loads, the square steel column supports vertical loads, and the steel truss is suitable for the large-span roof structure. As the core framework of modern buildings, the steel structure is renowned for its high strength, light weight, and modular design. It is an ideal choice for high-rise buildings, industrial factories, and bridge engineering.

Why Choose Steel Structure Buildings?
 
Material Characteristics

• High Strength and Light Weight: The strength of steel is more than three times that of concrete, and its self-weight is only one-third of that of traditional structures. This significantly reduces the foundation load and improves transportation and construction efficiency.

• Seismic Resistance and Toughness: Excellent plasticity and ductility enable it to withstand dynamic loads and seismic impacts. The uniformity of the material ensures the reliability of the structure.
Structural Performance
• Large Span Capacity: Suitable for column-free space design, such as in scenarios with extremely large spans like the roofs of sports stadiums and airport terminals.
• Rapid Assembly: Components are prefabricated in the factory, and the on-site assembly efficiency is high, shortening the construction period by 30%-50%.
Sustainability
• Green and Environmentally Friendly: The materials can be 100% recycled, and the construction process reduces construction waste, conforming to the trend of the low-carbon economy.
• Sealing Performance: The welded structure can meet the airtightness requirements of high-pressure vessels, oil storage tanks, etc.
Cost Savings
• Short Construction Time: Shortens the working hours of workers by 30%-50%, saving labor costs.
• Obvious Price Advantage: The cost is controllable, and the price can be lowered.

Factors Affecting the Price of Steel Structure Buildings:

1. Price of Steel Raw Materials
Significant fluctuations in the price of steel will directly lead to changes in the overall price of steel structure buildings.

2. Loads
This includes wind load, snow load, static load, and dynamic load. A larger load will require the use of more steel structures.

3. Span
Generally, the span of the steel frame will be controlled within 36 meters. The larger the span, the more steel will be used. If the steel frame has a large span and there is no middle column, the steel consumption per square meter will increase.

4. Structure
If the building has glass curtain walls, cranes, mezzanine floors, canopies, etc., in order to ensure safety, more steel
structures will be added.

If you are looking for a steel structure manufacturer with competitive prices and high quality, please contact us for suggestions.

Production Full Process and Quality Control System

Full-chain Process

• Raw Material Selection: High-purity iron ore and coke are used, and high-quality steel billets are formed through coking and sintering processes.
• Precision Rolling: The hot-rolling process shapes the cross-section of the section steel, the cold-rolling process improves the surface finish, and galvanizing/spraying enhances the corrosion resistance.
• Intelligent Welding: The full penetration welding technology ensures the strength of the joints, and numerical control equipment controls the dimensional error to be ≤ 0.5mm.
Key Quality Control Nodes
• 100% spectral detection is carried out for raw materials upon entering the factory, and both the chemical composition and mechanical properties are verified.
• Ultrasonic flaw detection and magnetic particle inspection cover all welds to eliminate internal defects.
• The finished products are scanned by a 3D laser to ensure a complete match with the design drawings.
Design Services
We can provide complete project drawings according to your requirements. By using AutoCAD, PKPM, MTS, 3D3S, Tarch, Tekla, etc., we can design complex industrial buildings such as office buildings, supermarkets, automobile dealership stores, shipping malls, hotels, etc.
Application Scenarios in Multiple Fields
• Super High-rise Buildings:
For example, the Shanghai Tower utilizes the steel structure to achieve a height of 632 meters and meet the design requirements for wind resistance and seismic resistance.
• Industrial Factories:

The large-span column-free space supports the layout of heavy equipment, meeting the needs of industries such as automobile manufacturing and aerospace. Infrastructure.

• Bridge Engineering:
The Hong Kong-Zhuhai-Macao Bridge adopts the steel box girder structure, taking into account both the span and durability.
• Public Facilities:

The National Stadium “Bird’s Nest” demonstrates the integration of artistry and functionality through the steel space frame. Special Engineering.

• Energy Facilities:
Offshore oil platforms adopt corrosion-resistant steel structures to adapt to the salt spray environment.
• Mobile Structures:

Modular steel structures are convenient for quickly building emergency buildings such as temporary hospitals and exhibition halls.
