Our semi-permanent prefabricated school buildings are designed to last 15+ years. The steel structure is manufactured with heavy-duty galvanized steel coated with anti-corrosion materials, making it highly resistant to harsh monsoons, humidity, and sun exposure.
Yes, absolutely. The structures feature pre-engineered bolt-connected components. We provide detailed installation manuals and clear 3D assembly drawings, enabling general local laborers to assemble the classrooms quickly using basic tools.
Yes. We prioritize child safety by sourcing 100% formaldehyde-free and non-toxic insulation cores. In addition, the walls use certified fire-retardant materials, and the window profiles are built with rounded PVC to prevent injuries.
The frame components are secured with structural sealant to lock all joints, making them waterproof. They are engineered to sustain high wind loads and heavy rainfall, maintaining a secure and dry interior learning environment.
Yes. To ensure project consultant and board approval, we offer dual-color insulated exterior cladding (such as Cream Yellow and Brick Red). This upgrade gives the temporary structures a high-end, professional look instead of a typical plain labor camp aesthetic.
Yes, our facility is equipped with dedicated quality inspectors who oversee every phase of the manufacturing process. Third-party quality inspection reports can be provided to meet your project specifications.
