As the global construction industry shifts toward carbon neutrality, eco-friendly and energy-efficient building materials have transitioned from a trend to a necessity. Sandong Building Materials, a leading innovator in the prefabricated sector, is at the forefront of this green revolution. By integrating advanced metal carved boards (insulated sandwich panels) with modular folding houses, the company is redefining sustainable and rapid-assembly architecture for a global market.

For modern architects, balancing aesthetics, thermal efficiency, and durability is a perpetual challenge. Sandong’s flagship product, the metal carved board, offers an elegant solution.
Superior Thermal Insulation: Engineered with a high-density polyurethane foam core and an aluminum-zinc alloy coated steel sheet, these panels offer exceptional thermal resistance ($R$-value), drastically reducing HVAC energy consumption.
Diverse Aesthetics & Durability: With hundreds of textures ranging from brick to wood grain, these panels feature a self-cleaning fluorocarbon coating that resists UV degradation and weathering for over 20 years.
Flame Retardancy: Meeting stringent international fire safety standards (B-grade fire resistance), they ensure maximum safety for commercial and residential applications alike.
Beyond exterior cladding, Sandong has leveraged its material expertise to develop highly efficient folding houses. Designed for disaster relief, temporary site offices, and affordable housing, these structures can be deployed in under 10 minutes.
By utilizing Sandong’s own metal carved boards as the wall system, these folding houses achieve a level of insulation and structural integrity that traditional container homes simply cannot match. This vertical integration allows Sandong to guarantee quality control from raw material to the finished modular home.
