Q235b Q355b Prefab Steel Structure Frame Building For Industrial Warehouse

Our high-strength steel building solutions are professional pre-engineered metal building systems designed for global commercial, industrial, and residential construction projects. Adopting advanced modular steel construction and standardized factory prefabrication technology, our steel building kit delivers unmatched durability, flexibility, and cost-efficiency.

We provide full-service prefab metal building solutions covering custom design, factory production, global delivery, and on-site steel building installation overseas service, catering to diverse global construction demands.

Our products excel in large span steel structure, long span construction, and wide span metal building scenarios, perfectly solving the space limitation problems of traditional buildings. All products are ISO certified steel building and CE certified steel structure, fully compliant with international construction standards, ensuring reliable performance for global projects.

To guarantee the ultimate stability and load-bearing capacity of steel structures, we strictly adopt high-quality Q235B Q355B steel frame as the core structural material, with complete international standard equivalence for global project adaptation:

• Q355B (China GB): Equivalent to ASTM A572 Gr.50 / EN S355JR / JIS SM490, featuring ultra-high tensile strength, suitable for high-rise, large-span and heavy-load building structures
• Q235B (China GB): Equivalent to ASTM A36 / EN S235JR / JIS SS400, with excellent ductility and stability, ideal for auxiliary frames and conventional structural components

Our core structural components adopt two mature production processes: welded H-section steel and Hot-rolled H-beam/Box beam column. The optimized section design realizes high strength-to-weight steel performance, making our lightweight steel building achieve higher structural strength with lighter self-weight. This feature greatly reduces foundation construction costs, shortens construction cycles, and improves the overall economic efficiency of the project.

• Standard Certification: Fully compliant with CE certification (EN 1090-1), ISO 9001 quality management system certification, ISO 3834 welding quality system certification, ISO 14001 environmental management system certification, and ISO 45001 occupational health and safety management system certification, meeting global construction safety specifications
• High Cost Performance: Lightweight design saves foundation cost, rapid construction shortens cycle, and long service life reduces later maintenance cost
• Strong Adaptability: Supports large-span, multi-storey and high-rise buildings, adapts to various climates and terrain conditions
• Green Environmental Protection: All steel materials are recyclable, with energy-saving insulation system, meeting global green building standards
• Simple Maintenance: Bolted assembly structure is convenient for later inspection, maintenance and structural expansion

Our steel structures are professionally optimized for extreme weather and environmental conditions, perfectly adapting to various global geographical environments:

• Wind Resistant Metal Building: Professional wind-resistant structural design, supports wind load 300km/h resistant, effectively resists extreme typhoons and strong winds, ensuring building stability in coastal and high-wind areas
• Earthquake Resistant Steel Building: The lightweight and high-toughness steel frame has excellent seismic performance, which can effectively buffer and disperse seismic force, reducing building damage risks in earthquake-prone areas

We equip all buildings with professional thermal insulation metal and insulated steel structure systems. The composite insulation envelope forms an efficient energy efficient steel envelope, which effectively isolates indoor and outdoor temperature differences, reduces air conditioning and heating energy consumption, and realizes green, low-carbon and energy-saving operation of the building throughout the year.

All our steel buildings adopt scientific bolt together steel frame and bolted steel frame assembly technology, abandoning traditional on-site welding operations. All structural components are precisely prefabricated and pre-drilled in the factory with unified standards, realizing fully modular assembly. This innovative structure brings multiple core advantages for global construction:

• Fast & Efficient Construction: Belonging to typical fast install steel building and rapid construction metal building systems, the easy erection steel construction mode cuts on-site construction time by 50%-70% compared with traditional buildings, greatly shortening project delivery cycles
• Stable & Durable Structure: The integral bolted frame structure avoids welding deformation and corrosion risks, forming a durable steel structure construction system with a service life of over 50 years under regular maintenance

As versatile prefab steel construction, it supports free combination and expansion of structures. Our prefabricated steel buildings are widely used in global construction fields, including industrial workshops, logistics warehouses, multi-story office buildings, residential apartment buildings, high-rise comprehensive buildings, large-span exhibition halls, stadiums, agricultural greenhouses and other commercial, industrial and civil construction projects.

We provide one-stop custom steel building design services, supporting personalized customization of size, span, floor number, appearance, function and auxiliary facilities according to customers' project requirements and local building codes. From preliminary scheme design, structural calculation, drawing confirmation, factory precision production to global logistics transportation, we deliver standardized full service prefab metal building solutions.

To solve customers' on-site construction problems overseas, we provide professional installation service metal building and steel building installation overseas support. Our professional engineering team can provide remote installation guidance or on-site supervision services to ensure standardized and accurate building assembly, guaranteeing project quality and construction progress.
