20ft Detachable Flat Pack Steel Sandwich Panel Container House Eco-friendly Waterproof Fireproof Modular Prefab Office Building

Structural Details: Precision welding and anti-corrosion coatings ensure robust safety foundations. The top and bottom frames, along with main and auxiliary beams, employ full-welding techniques and integrated corner component manufacturing, resulting in uniform welds free of pores. Combined with high-strength rust-resistant bolt connections, the structure achieves a wind resistance rating of Grade 11, seismic intensity of Grade 8, and a roof live load of 0.6 kN/m²

Export price advantages: Standardized production and bulk delivery reduce logistics and customs clearance costs. The flat-pack design allows each container to carry 8-12 sets of top and bottom frame assemblies, cutting logistics costs by 40%-50% compared to bulk shipping

Rapid Installation: Completing one container assembly requires only 2-3 personnel and 4 hours, without the need for heavy machinery. The top and bottom frames are fully prefabricated modular components that require only bolted connections on-site---no welding or cutting is needed. A team of 2-3 people can assemble one standard container in 4 hours, while a team of 10 people can install 10-15 containers per day, achieving an installation efficiency more than ten times higher than traditional construction methods

Flexible customization: On-demand configuration to create bespoke spaces. Customize colors, logos, curtain walls, skylights, and balconies to achieve a brand-aligned, visually stunning architectural design

Multi-scene Application:Widely used in construction site office, worker dormitory, engineering camp, disaster relief shelter, tourist scenic hotel, mobile store and temporary command center. Support arbitrary splicing and multi-layer combination. Customized appearance color, interior decoration, doors, windows and intelligent systems are available to meet diverse project and commercial needs
