Product Description

Steel Construction

Founded in 2005, EIHE STEEL STRUCTURE is a well-established manufacturer and supplier of steel structures. Equipped with standardized production workshops, mature processing technologies and a complete quality inspection system, we focus on providing global customers with high-quality and highly adaptable customized steel structure products. 

As a modern green building solution, Steel Construction adopts steel structures as the core load-bearing system. Fabricated with section steel and steel plates via welding, bolting and other connection processes, our steel construction products are widely applicable to various industrial, commercial, civil and special building scenarios. Benefiting from excellent product performance, convenient transportation conditions and efficient services, our products are sold well at home and abroad. Up to 2025, we have gained cooperation and trust from more than 500 clients worldwide.

THE DEFINITION OF Steel Construction

Our Steel Construction is a green building product manufactured with high-strength Q355B/Q235B steel as the core material, adopting advanced CNC digital processing and hot-dip galvanizing anti-corrosion technology. It features excellent earthquake resistance, superior anti-corrosion performance, fast construction and recyclability. Compared with traditional concrete structures, our steel construction is lightweight yet high-strength, which greatly reduces foundation costs on soft soil foundations while ensuring outstanding seismic performance. 

It achieves a maximum span of over 60 meters and supports high clearance and complex architectural shape designs. Adopting BIM optimized design enables flexible later expansion. All components are prefabricated in the factory under strict quality control. On-site dry operation effectively reduces construction noise and construction waste, fully complying with environmental protection standards. In addition, coordinated factory prefabrication and on-site construction greatly improve prefabrication and assembly efficiency, realizing fast project delivery.

Applications of Steel Construction

Steel Construction is widely applied in industrial manufacturing, logistics and warehousing, commercial and public architecture, agriculture and animal husbandry, as well as temporary and emergency facilities, serving as an optimal solution for lightweight, efficient and high-quality construction of overseas engineering projects. 

In industrial manufacturing, it is ideal for heavy machinery workshops, steel smelting workshops and chemical warehouses, capable of bearing large-tonnage overhead cranes and adapting to environments with corrosive gases. 

For logistics and warehousing scenarios including e-commerce storage bases and cold chain logistics centers, it creates ultra-large sorting spaces, and combines multi-layer steel platforms and mezzanine systems to maximize vertical space utilization. 

In terms of commercial and public buildings, it is widely used in large shopping malls, auto 4S stores, exhibition centers, office buildings, industrial parks, schools, hospitals, stations, terminals, parking lots, stadiums, broadcasting buildings and suspension bridges. Equipped with transparent glass curtain walls and flexible floor layouts, the prefabricated steel structure supports rapid construction and early occupancy. 

For agriculture and animal husbandry, it applies to steel-structured livestock houses, greenhouses, agricultural machinery warehouses, grain warehouses, aquaculture warehouses and photovoltaic support steel structures, featuring economical cost, adjustable ventilation and lighting, and excellent resistance to ammonia corrosion. 

For temporary and emergency facilities such as, mobile cabin hospitals, temporary teaching sites and emergency resettlement houses, the structure supports quick assembly and disassembly and reusable turnover use, enabling large-area construction completion in a short period.

Production Process of Steel Construction

The production process of steel Construction consists of four core stages: pretreatment and blanking, forming and hole fabrication, anti-corrosion and surface treatment, as well as pre-assembly and overall inspection.

Stage one: Steel materials are pretreated via shot blasting for rust removal. Intelligent manufacturing equipment such as CNC flame and plasma cutting machines, operated by professional technicians, are used for precise blanking and cutting, achieving millimeter-level machining accuracy.

Stage two: Workpieces are transferred to CNC assembling machines for the assembly of H-shaped or box cross-sections. Subsequent welding and hole fabrication are carried out by submerged arc welding robots, automatic gantry welding machines, CNC 3D drilling machines and on-site production workers, with all welds meeting Class I quality standards.

Stage three: Secondary shot blasting is performed to reach the Sa2.5 rust removal grade, followed by conveyance to an automatic coating line for priming, intermediate coating and top coating. If hot-dip galvanizing is adopted, the zinc coating thickness can exceed 85 micrometers.

Stage four: Partial full-scale pre-assembly is conducted prior to factory delivery. Inspections are carried out on bolt hole penetration rate and joint alignment accuracy to guarantee qualified finished products and seamless on-site erection.
