The Lightweight Custom EPS Sandwich Panel is a next-generation decorative and functional building material designed for B-end clean building and industrial enclosure projects, focusing on lightweight construction and customizable performance. The panel takes flame retarding EPS (Polystyrene) as the core material, paired with galvanized steel, stainless steel, or pre-painted galvanized color sheet surface layers, and is compounded through high-speed continuous molding machine heating and pressing. As a custom lightweight EPS panel with Lever B fire resistance and an oxygen index of 43.0, it balances flame retardancy, thermal insulation, and cost-effectiveness, and its lightweight structure reduces building load while meeting the high airtight and clean requirements of modern industrial projects. It is a preferred material for B-end clients in electronics, food, pharmaceuticals, and other industries pursuing high-standard, customizable building enclosures.
Superior Flame Retardancy: With Lever B fireproof rating and an oxygen index (OI) of 43.0, the flame retarding EPS sandwich panel has excellent self-extinguishing performance, effectively inhibiting flame spread and meeting fire safety requirements for clean buildings and general industrial areas.
Flexible Connection Design: Equipped with Tongued and Grooved and H form double connector types, it adapts to different construction scenarios (wall, roof, partition), enabling seamless splicing and easy assembly, which shortens on-site construction period.
Lightweight & High Adaptability: With a bulk density of 12-24kg/m, it is ultra-lightweight, reducing the load of steel structure and concrete buildings, and is suitable for multi-storey industrial workshops, prefabricated buildings, and temporary high-standard enclosures.
Diverse Surface Material Options: Surface layers can be customized with galvanized steel, stainless steel, or pre-painted galvanized color sheets, meeting anti-corrosion, anti-rust, and aesthetic requirements of different B-end projects. Clean & Eco-friendly: The flame retarding EPS core is non-toxic and odorless, without volatile harmful substances, complying with clean room environmental standards, and is an ideal material for clean building EPS sandwich panel applications.

Carry out Pre-installation Check to verify panel specifications, surface material integrity, and connector precision; for clean room projects, select stainless steel surface panels and ensure no dust or impurities on panel surfaces. Implement Base Layer Adaptation as the panel is compatible with steel purlin, concrete, and masonry base layers, and ensure base flatness (deviation ≤5mm/2m) and clean the surface to avoid affecting bonding strength. Conduct Flexible Assembly by choosing Tongued and Grooved for wall partitions and H form for roof enclosures according to project needs, adopting quick splicing with dedicated clamps (no complex tools required) and installing from one side to the other to ensure neat arrangement. Complete Airtight Sealing; for clean building applications, fill splicing seams with food-grade or medical-grade sealant to meet high airtight requirements, and use waterproof gaskets for outdoor projects to prevent water seepage. Achieve Efficient Construction as the lightweight design allows manual handling and installation, reducing the need for hoisting equipment; the whole assembly process is dry construction, no wet work, which shortens the project cycle by 30% compared with traditional materials.
As a versatile clean building EPS sandwich panel, it is widely used in B-end high-standard projects, including: clean rooms for electronics, food, pharmaceutical, and hospital industries, military clean construction projects, high-standard industrial workshops and warehouses, prefabricated modular buildings, HVAC clean room enclosures, and light steel structure buildings (office partitions, shopping mall decorations). Its lightweight and customizable features also make it suitable for temporary high-standard construction projects (e.g., mobile medical centers, temporary logistics warehouses).
Centered on B-end clients’ personalized project needs, we provide one-stop customization services with flexible solutions. Offer Surface Material Customization to tailor surface layers (galvanized steel/stainless steel/pre-painted galvanized color sheet) and steel sheet thickness (0.3-0.5mm) according to project anti-corrosion and clean requirements. Provide Color & Aesthetic Customization with a variety of pre-painted colors (white, gray, blue, red, etc.) for the surface layer to match the overall design of the project. Realize Dimension Customization by customizing panel length within standard width (950mm/1150mm) for on-site construction convenience, and support non-standard thickness customization for special thermal insulation needs. Implement Core Material Optimization by adjusting flame retarding EPS density to enhance thermal insulation or structural performance for different temperature environments. Supply comprehensive B-end Project Support including professional 3D design drawings, on-site technical guidance, and after-sales online technical support for bulk projects, and offer a 5-year quality warranty for core components.
Its EPS core is non-toxic, odorless, and free of volatile harmful substances, complying with GMP pharmaceutical clean room standards; the stainless steel surface option is easy to clean and disinfect, and the airtight splicing design prevents dust accumulation, fully meeting the clean requirements of pharmaceutical production.
Yes. The H form connector type is specially designed for roof applications, with strong load-bearing capacity and excellent wind resistance; matching with waterproof sealant treatment, it can effectively prevent water seepage and meet the long-term use needs of large-scale warehouse roofs.
For standard specification bulk orders (≥1000 meters), the delivery cycle is 15 working days; for non-standard customized orders, the delivery cycle is determined according to the customization complexity (generally 20-30 working days), and we support urgent order scheduling for key B-end projects.
