Overview:
Sandwich panels are essential in cleanroom construction for creating and maintaining contamination-controlled environments. Their seamless surfaces, tight joints, and smooth finishes prevent particle accumulation and allow easy disinfection, while the insulated core helps regulate temperature and humidity. These panels are widely used in pharmaceuticals, electronics, food processing, healthcare, and other industries requiring strict environmental control.
Introduction detail:
Clean room sandwich panels are main products in clean room engineering, which are flame retardant, soundproof and environmentally friendly. The Clean room panel is made up of two layers of metal panels and a functional material from the middle. It has the characteristics of easy installation, light weight and environmental protection. Moreover, the functional materials used for filling can be chosen according to different environments and production requirements. Currently, the core functional materials we can provide are: PU, PIR, Rock Wool, Aluminum Honeycomb, Paper Honeycomb, Magnesium and etc.
Classification:
Rockwool sandwich panel
Rock Wool sandwich panel are usually used for wall or ceilings that have certain requirements for fire resistance. In addition, it has very good thermal insulation properties. Most customers like the rock wool sandwich panels. Rockwool sandwich panels are commonly used in clean room engineering in electronics and pharmaceutical plants. Rock wool is a kind of inorganic fiber board which is made of basalt as the main raw material and melted at high temperature. Rock wool board is a new type of heat preservation, flame insulation and sound absorption material.
The artificial inorganic fiber processed by high temperature melting of rock wool board has the characteristics of light weight, small thermal conductivity, heat absorption and non-combustibility.

Honeycomb sandwich panel
Honeycomb core introduction: Aluminum hexagonal honeycomb, low density, 1/5 of the same thickness of the same board, 1/6 of the glass, 1/7 of the aluminum, greatly reducing the construction load and cost, because the middle interlayer contains a lot of air, Sound insulation (air insulation up to 30dB), heat insulation (thermal resistance up to 0.02 (m2 · K / W)), no flammable substances, fire rating up to A1, waterproof, moisture-proof, no harmful gas release, aluminum honeycomb panel surface It has extremely high flatness and good seismic performance, only one-eighth of the specific gravity of the glass curtain wall; the 22mm thick standard can achieve a load of 700 kilograms or more at a simple support of 1 meter and a deflection of 10mm. Aluminum honeycomb panels have been widely used in clean room partitions and ceilings due to their advantages of light weight, high strength and high rigidity.

Stainless steel panel&Aluminium panel:
Sandwich panels are engineered building systems that combine structural metal facings with insulated cores, providing strength, efficiency, and environmental control. This FAQ addresses key aspects of their application, performance, and customization to help you select the right solution for your project.
A sandwich panel is a high-performance composite building material engineered as a "sandwich" structure. It consists of two durable metal facings (typically pre-finished galvanized steel or aluminum) permanently bonded to a lightweight insulating core material.
As a dedicated clean room panel supplier, our panels are engineered for precision-controlled environments. Their primary applications are in industries where hygiene, temperature stability, and contamination control are critical. This includes the pharmaceutical and biotech sectors for GMP facilities, the electronics and semiconductor industry for static-sensitive production areas, the food & beverage industry for hygienic processing zones, and healthcare for operating rooms and labs.
Our panels offer a superior, all-in-one solution that accelerates project timelines and enhances performance. Key advantages include exceptional thermal efficiency leading to significant energy savings, rapid installation due to large, prefabricated sections, and superior hygiene with seamless, easy-to-clean surfaces ideal for clean room panels.
As a proficient cleanroom panel manufacturer, we ensure high structural strength-to-weight ratios, excellent fire ratings from core material options, and extensive design flexibility for various cleanroom wall and cladding applications.
We offer a range of core materials to meet specific project requirements for fire safety, insulation, and budget. Our main types include Rock Wool (A2-s1, d0 non-combustible, excellent for fire-rated clean room partitions), Polyisocyanurate (PIR) / Polyurethane (PU) (superior thermal efficiency with Class B-s1, d0 fire rating, perfect for cold rooms), and Magnesium Oxide (MGO) boards (A-class non-combustible with high moisture resistance).
Fire safety is paramount. Our panels are rigorously tested and certified to global standards. Rock Wool and MGO cores achieve the highest A2-s1, d0 (EN 13501-1) / Class A (ASTM E84) non-combustible ratings. Our PIR cores typically achieve Class B-s1, d0 (EN) / Class 1 (ASTM E84).
Precision is non-negotiable for seamless clean room wall panels and ceilings. We achieve this through fully automated, computer-controlled continuous laminating lines that apply consistent high pressure and temperature, ensuring perfect bonding and uniformity.
We implement a rigorous color management protocol. For a single project, we use pre-coated metal coils from the same manufacturer and the same production batch. For large projects requiring multiple batches, we work closely with our coating suppliers to secure sequential batches with the highest possible color match. We also provide detailed guidance on-site installation sequencing to visually blend any minimal, unavoidable variation, ensuring a uniform appearance for all cleanroom wall surfaces.
Yes, we are a direct cleanroom panel manufacturer with full vertical integration. We operate state-of-the-art, automated production lines where the entire process—from raw material inspection to composite forming and cutting—is controlled in our facility. This allows for strict, real-time quality control at every stage, from core density verification to adhesive application and final dimensional inspection, guaranteeing the consistent performance of every clean room panel we ship.
We have a robust portfolio of successful projects worldwide. Our clean room panels and systems have been installed in pharmaceutical cleanrooms across Europe, semiconductor fabrication plants in Southeast Asia, high-care food processing facilities, and research laboratories in the Middle East and Africa. We can provide anonymized case studies, technical data sheets, and, with client consent, references or project photographs that demonstrate our capability as a trusted clean room panel supplier for complex builds.
We employ industry-leading packaging to ensure products arrive in perfect condition. Each panel is carefully stacked, protected with heavy-duty edge guards and corner protectors, and then securely shrink-wrapped onto reinforced wooden pallets.
Proper handling is crucial. Panels must be unloaded using forklifts with padded forks, never dragged or lifted by a single point. On-site, they must be stored horizontally on a flat, level surface, supported evenly along their length by timber dunnage. Stacks should be kept to a reasonable height to prevent deformation, and the entire stock must be protected from the elements with waterproof tarpaulins. Following these steps preserves the integrity of the cleanroom wall and partition materials before installation.
