The Handmade Customizable Magnesium Rockwool Panel is a high-performance composite building material engineered for industrial and cleanroom construction, designed exclusively for B-end clients in high-standard construction projects. Composed of a layered structure of PPGI (pre-painted galvanized steel) + glass magnesium board + rock wool + glass magnesium board + PPGI, this panel is crafted via precision pressing and high-temperature heating processes, forming a highly airtight and fire-resistant sheet with exceptional structural stability. Its core design integrates moisture-proof glass magnesium as the base core material and high-density rock wool as the insulation layer, paired with galvanized steel side covers and reinforcing ribs for enhanced load-bearing capacity. Easy to install and fully customizable, this magnesium rockwool panel is the ideal building solution for walls, partitions and ceilings in controlled-environment facilities, delivering uncompromising performance in fire resistance, thermal insulation and soundproofing—core demands for B-end engineering and procurement teams.
Classified as Level A fire resistance performance, the panel is completely non-inflammable and releases no toxic gases when exposed to high temperatures, complying with the strictest industrial fire safety standards. The 100kg/m³ high-density magnesium plate core material and rock wool insulation layer form a double fireproof barrier, making it suitable for fire-critical areas such as pharmaceutical cleanrooms and electronic production workshops.
With a thermal insulation coefficient of 1.8kcal/m²/h/℃ and 30dB sound insulation performance, the panel effectively blocks heat transfer and reduces industrial noise interference. The closed-cell structure of rock wool minimizes heat loss, while the glass magnesium board enhances thermal stability, lowering long-term energy consumption for B-end clients’ HVAC systems.
Reinforced with galvanized steel ribs and side covers, the panel resists deformation and cracking under heavy loads, with a uniform weight of 22kg/m² for balanced structural stress. The moisture-proof glass magnesium core material prevents water absorption and mold growth, maintaining performance in high-humidity environments such as food processing plants and medical labs.
The high-temperature pressing process ensures excellent airtightness, meeting the airtightness requirements of cleanroom construction. Adopting tongue and groove and Character Zhong-Types connection methods, the panel enables fast on-site assembly without complex tools, significantly shortening construction periods for B-end project teams.

Inspect panel dimensions and surface quality for B-end project consistency; store panels in a dry, ventilated area with a 30cm elevation to prevent moisture.
Prepare basic tools (electric drill, tape measure, cutting machine) and auxiliary materials (fireproof sealant, galvanized gaskets) matching the panel’s fire rating.
Ensure the construction base has a flatness deviation ≤5mm/2m and complete pre-embedded pipelines (HVAC, fire protection).
Fix the galvanized steel keel to the base with expansion bolts (spacing ≤600mm) for stable support.
Assemble panels via tongue and groove/Character Zhong-Types connection, with a lap joint width ≥20mm for airtightness; fix panels to the keel with self-tapping screws (spacing ≤200mm).
Fill joints with A-grade fireproof sealant and cover with aluminum press strips to enhance airtightness and structural integrity.
Verify panel flatness (deviation ≤2mm/2m) and verticality (deviation ≤3mm/3m) with a level ruler.
Test airtightness at joints and connections to meet cleanroom pressure difference requirements.
Inspect screw fastness and sealant continuity to avoid water and air leakage.
