1. Product Overview

The ZSJH Double-Wing Expandable Folding House is a factory-prefabricated modular unit that travels in a compact form and unfolds on site to create a wider usable space. The integrated steel frame, wall and roof assemblies, doors, windows and optional interior systems support faster deployment with less site work than conventional construction. Standard 10 ft, 20 ft, 30 ft and 40 ft concepts can be adapted for homes, accommodation, offices, retail spaces and project facilities. Single-storey layouts are the most transport-efficient; engineered two-storey and three-storey schemes are available through project-specific modular combinations, foundations, bracing and connection design.
