Foshan Samzoon Sandwich Panel Co., Ltd. customized a 1,980 ㎡ constant-temperature and constant-humidity workshop for a mushroom cultivation base in Gaoming, Foshan, using 100 mm double-sided color steel foam sandwich panels as the thermal insulation structural layer and 50 mm hollow glass-magnesium sandwich panels with single-sided color steel plus stainless steel surface as the inner wall surface layer. This combined solution addresses the core pain points of mushroom cultivation workshops—moisture-proofing and mold prevention, high-humidity resistance, easy cleaning, and constant temperature and humidity—verifying the adaptability of cleanroom sandwich panels in agricultural cultivation scenarios and serving as a benchmark case for the industry.
