In order to ensure the structural airtightness of the production workshop, functional partition wall panels and ceiling panels with environmental control indicators are mostly made of sandwich color steel plates that comply with national fire safety regulations. There are strict requirements for the flatness, filling materials, structural form, fire resistance limit, steel plate thickness, compressive strength, and other aspects of the color steel plates. According to the design requirements, manual double-layer glass magnesium rock wool color steel plates, manual glass magnesium hollow color steel plates, self-made rock wool color steel plates, and manual rock wool color steel plates can be used.
