I. Product Overview

Rigid box section Steel Structure is a kind of closed box section structure welded or bolted by high-strength steel, which has the core advantages of high strength, high rigidity, light weight and multi-functionality. Its cross-section is usually rectangular or square, and the internal partitions can be used to enhance the load-bearing capacity. It is widely used in industrial plants, bridge projects, sports stadiums, high-rise buildings, heavy equipment support and other fields, and is an ideal choice for replacing the traditional concrete structure in modernization projects.

II. Product structure and characteristics

High strength and rigidity design

Made of high-quality Q345B/Q355B and above high-strength steel, the box section has uniform force, excellent bending and torsion resistance, and can withstand complex loads (e.g. dynamic loads, wind loads, earthquake loads, etc.).

Internal longitudinal or transverse stiffening ribs are added to significantly improve local stability and overall load carrying capacity.

Light weight and efficient use of space

Compared with concrete structure, the weight is reduced by 30%-50%, which reduces the cost of foundation and shortens the construction period.

The interior of the box can be pre-buried with pipelines or filled with fire/acoustic insulation materials to enhance the integration of building functions.

Excellent durability and environmental protection

The surface is hot-dip galvanized, sandblasted to remove rust + multi-layer anti-corrosion coating (epoxy zinc-rich primer + polyurethane top coat), with a weather resistance of more than 20 years.

The steel is 100% recyclable, in line with the concept of green building and sustainable development.

Modular construction and high precision assembly

Factory prefabricated production, dimensional accuracy of ±2mm, reducing the amount of on-site welding, shortening the construction period by more than 50%.

Supports bolted or welded joints, flexibly adapting to the needs of various projects.

III. Main Application Areas

Industrial buildings: large-span roof frames and columns of heavy factories, warehouses and logistics centers.

Public facilities: stadium domes, high-speed rail station canopies, airport terminal building steel structure.
