（It can also be handmade.）Cold storage panels are mainly made of polyethylene and polystyrene as raw materials. It can be foamed to obtain properties such as appropriate density, good thermal insulation effect, non-hygroscopicity, and high load-bearing capacity.
（It can also be handmade.）Rock wool is an inorganic fiber core material, mainly made from basalt and processed through high-temperature melting. It has the characteristics of low density, low thermal conductivity, excellent thermal insulation, sound absorption and noise reduction properties, and non-combustibility.
（It can also be handmade.）The integration of magnesite boards with rock wool cores creates a superior fireproof composite system, achieving enhanced flame-retardant performance (A1 grade) while expanding application versatility across diverse construction scenarios. Magnesium Oxide Board Sandwich Panel Stuffed with Rock Wool.
（It can also be handmade.）Silica Rock Composite Panels are engineered through advanced extrusion technology, and these eco-friendly insulation boards combine polystyrene resin with polymer additives under precise thermal catalysis, delivering revolutionary performance.
（It can also be handmade.）The magnesium oxychloride sandwich panel can be directly painted, veneered, fixed with pneumatic nails, and tiled directly. The surface has good colorability. It has high strength, toughness when bent, and is extremely convenient for decoration. It can be sawn, nailed, and glued.
The exterior surfaces of the hand-made sandwich panel can be made of specific metal materials such as pre-painted steel sheets, galvanized steel sheets, and stainless steel sheets. And ideal applications are : modular cleanrooms, retrofitting projects and temporary containment walls.
The sulfur-oxygen-magnesium sandwich panel is a lightweight material composed of industrial waste materials such as magnesium oxide, magnesium sulfate and straw powder as the surface material, reinforced by alkali-resistant glass fiber mesh cloth, with light aggregate foamed boards such as polystyrene board, extruded board and foamed cement insulation board as the core material, and appropriately added with modified admixtures.
The acoustic sandwich panel is mainly used to absorb and disperse sound, reducing the generation and propagation of noise. Acoustic panels (also sound absorption panels, soundproof panels or sound panels) are sound-absorbing fabric-wrapped boards designed to control echo and reverberation in a room. Most commonly used to resolve speech intelligibility issues in commercial soundproofing treatments.
The paper honeycomb sandwich panel is composed of two upper and lower panels and a paper honeycomb core material in the middle. The paper honeycomb core material is arranged in a unique hexagonal honeycomb structure. This structure not only ensures the light weight of the panel but also endows it with high strength and stiffness.
The upper/lower surfaces are made of Baosteel or Wusteel plates with a thickness of 0.3–1.0 mm.
The core material consists of aluminum honeycomb, bonded with thermosetting adhesive and hot-pressed in continuous forming machine to create a composite building panel.
The side steel strips are made of 0.5 mm thick galvanized steel sheets.
A "hidden beam" is a type of beam embedded within floor slabs, shear walls, or other structural components in architectural structures, blending seamlessly with the surrounding elements without visible exposure. Its primary purpose is to enhance the mechanical performance of the structure while maintaining spatial layout and aesthetics.
Slot aluminum typically refers to an aluminum alloy profile with a cross-sectional shape of a channel (similar to channel steel）, combining the lightweight, corrosion resistance, and machinability of aluminum. It finds extensive applications across various industries.
