PS wall panels are interior wall cladding products made from polystyrene resin with functional additives. Produced by Shandong Demax Group, these panels carry SGS, CE, UL, and ISO certifications. Designed for interior wall installation, they serve commercial procurement needs in office fit-outs, retail spaces, hospitality venues, and residential projects where fast installation and low maintenance are priorities.
| >> Lightweight ConstructionPS wall panels have a low density that makes them easy to transport, handle, and install on site. The reduced weight lowers structural load requirements on existing walls, which is relevant for renovation projects where substrate capacity is limited. The light weight also contributes to lower shipping costs per square meter compared with solid wood or MDF panels. |
| >> Moisture-Resistant SurfacePolystyrene does not absorb water, which means PS wall panels resist moisture-related issues such as swelling, warping, and mould growth in humid indoor environments. This property supports their use in bathrooms, kitchens, basement areas, and other spaces where humidity levels are higher than average. |
| >> Fast Installation with Concealed FastenersPS wall panels install using a concealed fastener system. The tongue-and-groove profile allows panels to click together and be secured with hidden clips or adhesive, resulting in a seamless finished surface. For commercial fit-out projects, this installation method reduces on-site labour time compared with tiling or plastering. |
| >> Low Maintenance and Easy CleaningThe smooth surface of PS wall panels can be cleaned with soap and water. Unlike painted walls that require repainting over time, PS wall panels retain their finish with routine wiping. This reduces ongoing maintenance costs for property managers and facility operators. |
| >> Customisable FinishesPS wall panels are available in White, Grey, Black, and Wooden finishes, with custom colour options available for volume orders. The standard profile dimension is 150×12mm, and custom sizes can be arranged based on project specifications. |
PS wall panels are produced through an extrusion process. Polystyrene resin is mixed with functional additives including fire retardants, stabilisers, and colour concentrates. The mixture is heated to a molten state and extruded through a die that forms the panel profile. After rapid cooling in a water bath, the panels receive a surface film coating for colour and texture, then are cut to specified lengths. Finished panels undergo quality inspection and are packaged for shipment.
| Material PreparationPremium PVC and supplementary components are mixed thoroughly to form a consistent, uniform composite mixture ready for further processing. |
Thermal Mixing ProcessThe compound is heated and continuously agitated at the same time, ensuring it reaches the optimal viscosity required for forming. |
|
| Profile FormationThe thermally processed material is pressed through calibrated molds, producing substrate sheets with stable dimensions and reliable quality. |
Rapid Cooling Right after formation, the panels enter a precise cooling system to stabilize their molecular structure, maintaining accurate dimensions and excellent mechanical performance. |
|
| Surface Finishing Advanced lamination technology is used to apply decorative and protective films to the panels, enhancing their appearance and resistance to external environmental influences. |
Precision Cutting Automated cutting equipment trims the panels to exact sizes and specifications, ensuring uniformity and seamless compatibility during installation. |
|
| Protective Packaging Finished panels are wrapped and padded systematically with protective materials to keep them in perfect condition during storage and transportation. |
The installation of PS wall panels follows a step-by-step process. First, the wall surface is prepared — cleaned, dried, and levelled as needed. Reference lines are marked on the wall to guide alignment. Panels are cut to size using a utility knife or fine-tooth saw. Adhesive is applied to the back of each panel, and the panel is pressed onto the wall starting from one corner. Each subsequent panel clicks into the previous one via the tongue-and-groove joint. Hidden fasteners provide additional mechanical hold. Corner trims and edge mouldings complete the installation. The adhesive requires curing time before the wall is put into full use.
Step 1 Prepare the Surface
Ensure the wall or floor surface is clean, smooth, and dry before starting installation. Remove any dirt, grease, or irregularities.
Step 2 Measure and Cut
Measure the area where the sheet will be installed and cut the PVC Marble Sheet to the required dimensions using a utility knife or specialized cutting tools.
Step 3 Apply Adhesive
Evenly apply adhesive on the back of the PVC Marble Sheet and the installation surface. Use a trowel to ensure a consistent layer.
Step 4 Fix and Press
Place the sheet onto the surface and press it firmly, ensuring there are no air bubbles trapped beneath. Adjust alignment if necessary.
Step 5 Seal Edges
Seal the edges with silicone or a similar material to prevent water seepage and ensure a seamless look.
Step 6 Clean the Surface
Wipe the installed sheet with a damp cloth to remove any adhesive residue.
PS wall panels are used in office lobbies, meeting rooms, and corridor walls. The panels deliver a clean, finished appearance and support fast-track fit-out schedules for commercial tenants.
Retail stores, boutiques, and exhibition venues use PS wall panels to create feature walls and display backdrops. The variety of finish options supports brand-aligned interior design schemes.
In hotels, restaurants, and cafes, PS wall panels are installed on interior walls in dining areas and guest corridors. The moisture-resistant surface supports regular cleaning routines in food service environments.
