20FT 30FT 40FT Available Insulated Modern Expandable Steel Folding Container

Material: the main frame is made of high-strength Q235B galvanized steel with dual treatments of hot-dip galvanizing and electrostatic spraying. This steel exhibits high yield strength, enabling it to effectively withstand tensile and compressive stresses during box expansion and folding, while ensuring robust structural integrity and resistance to deformation. A dense protective oxide layer forms on the steel surface, providing excellent rust-proofing, corrosion-resistant, and oxidation-resistant properties, making it suitable for various complex outdoor applications

Affordable price & high utilization rate: in terms of comprehensive use cost, our expansion boxes feature one-time investment and long-term reuse. Different from disposable traditional brick temporary buildings and simple movable houses, they can be repeatedly folded, expanded, relocated and reassembled without repeated procurement and construction costs

Quick installation: the installation process is extremely simple and efficient with zero infrastructure requirements and rapid deployment. No professional construction teams, concrete foundation pouring or complex welding operations are needed. The whole setup can be completed by a single person or a small team

Design: our expandable container house adhere to a four-dimensional design concept of practicality, humanization, modularization and customization, balancing structural safety, space utilization, aesthetic appearance and scenario adaptability.Its extension mechanism ensures smooth and stable operation with precise lock alignment; when deployed, it distributes forces uniformly while exhibiting exceptional resistance to tipping and deformation, capable of withstanding winds up to 10-12 on the Beaufort scale as well as conventional earthquakes

Export Products: Our company specializes in various standard expansion boxes, customized irregular-shaped expandable container house, and multifunctional integrated expansion enclosures
