What are the advantages of not tiling ultra wide non-metallic shells

source：www.taicredit.cn  |  Release time：2025年06月04日
     Non tiling ultra wide non-metallic shells usually refer to shell structures made of polymer composite materials (such as PP, PE, ABS, FRP, etc.) or special concrete non-metallic materials, with a width exceeding traditional specifications (such as ≥ 800mm), without the need for additional decorative layers such as tiles or stone. Its core advantages are reflected in material performance, construction efficiency, functional adaptability, cost control, and environmental characteristics, as follows:
1、 Material performance advantages
1. Balance between lightweight and high-strength
      Using fiberglass reinforced polymer (FRP) or modified polypropylene (PP-GF), the density is only 1/4-1/3 of steel (about 1.2-1.8g/cm 3), but the tensile strength can reach 150-300MPa (close to Q235 steel), meeting the structural stability requirements of ultra wide spans (such as no deformation when a single span is ≥ 1.2m).
      Compared to traditional brick masonry, the weight is reduced by 60% -80% under the same span, reducing the load-bearing requirements for the base layer, especially suitable for old house renovation or floor load limited scenarios.
2. Corrosion resistance and impact resistance
      Non metallic materials naturally resist acid and alkali corrosion (such as corrosion resistance level ≥ F2 in pH 2-13 environment), suitable for high corrosion scenarios such as humidity, chemical industry, and ocean, avoiding the problem of traditional tile joints falling off due to cement corrosion.
      The surface is treated with a nano coating, which improves the impact resistance by 30% (such as being able to withstand the impact of a 1kg steel ball falling freely from a height of 1m without breaking), and the noise during collision is less than 50dB (traditional ceramic tile collision noise is about 70dB), suitable for quiet environments such as hospitals and schools.
3. Surface self-cleaning and maintenance free
      The surface of the shell is coated with a hydrophobic and oleophobic layer (contact angle ≥ 110 °), making it difficult for stains (such as water stains, oil stains, and dust) to adhere. Daily cleaning only requires wiping with clean water, reducing maintenance costs by more than 70% compared to tiled walls.
      Special process: Some products are formed with scratch resistant surfaces (hardness ≥ 2H) through in mold coating technology (IMD), which can be used for a long time without scratches and maintain the smoothness at the factory.
2、 Construction efficiency advantage
1. Modular quick installation
      The shell adopts factory prefabricated modular design (single module width can reach 2m, length can be customized as needed), and is quickly fixed on site through snap on splicing or adhesive. The installation efficiency is 5-8 times higher than traditional tiling process (installation on a 100 ㎡ wall only takes 1-2 days).
      No need for base treatment: can directly cover old walls (with a flatness of ≤ 3mm/m), without the need to remove existing tiles or plaster layers, saving time and construction waste.
2. Moisture free operation and zero pollution
      The construction process does not require wet working materials such as cement mortar and tile adhesive, and there is no dust or sewage discharge on site. It meets the "zero formaldehyde" standard for indoor decoration (volatile organic compound VOC ≤ 10g/L) and can be installed and used immediately. It is suitable for environmentally sensitive places such as hospitals and food workshops.
      Advantages of winter construction: Composite materials can be installed normally in environments ranging from -20 ℃ to 60 ℃ without temperature restrictions, while traditional tiling processes require the addition of antifreeze below 5 ℃, which may extend the construction period by 30%.
3、 Advantages of functional adaptability
1. Seamless effect of ultra wide format
      Traditional ceramic tiles are limited by specifications (such as 1200 × 2400mm), and ultra wide walls require a large amount of splicing, while non-metallic shells can have a single width of 3-4m, greatly reducing splicing (such as a 20m wide wall that only requires 5-7 pieces of splicing), visually neater, and avoiding dirt and grime accumulation between joints.
      Arc/Shape Adaptation: Curved shells (bending radius ≤ 500mm) can be made through hot pressing technology to meet the requirements of wrapping irregular structures such as circular columns and curved walls. Traditional ceramic tiles are difficult to achieve such complex shapes.
2. Multi functional integrated design
      The shell can be built with thermal insulation layer (such as XPS/EPS foam, thermal conductivity ≤ 0.03W/(m ? K)), sound insulation layer (filled with rock wool, sound insulation ≥ 35dB) or electromagnetic shielding layer (metal mesh composite structure) to achieve the integration of "decoration+function" and reduce multi process construction conflicts.
      Case: When applied in data center rooms, the ultra wide non-metallic shell can simultaneously meet the needs of wall decoration, sound insulation and noise reduction, and electromagnetic shielding, with a comprehensive cost reduction of 40% compared to traditional tiling and multi-layer ceiling solutions.
4、 Cost control advantage
1. The overall cost is lower than traditional craftsmanship
Taking the 100 ㎡ bathroom wall as an example:
      Traditional tiling: ceramic tiles (800 × 800mm, 80 yuan/piece)+accessories+labor ≈ 180 yuan/㎡, construction period of 7 days;
      Non metallic shell: Composite material (including installation) ≈ 220 yuan/㎡, construction period of 2 days, comprehensive cost reduced by about 30% (considering the labor and management cost savings caused by the shortened construction period).
      Long term cost: The maintenance free feature saves about 500 yuan/square meter in maintenance costs over a 10-year period, which is much lower than the cost of tile joint filling, tile patching, and other expenses.
2. Reduce implicit costs
      To avoid safety hazards caused by tile hollowing and falling off (such as the risk of injury), and reduce maintenance disputes in the later stage;
      The lightweight feature reduces the main load of the building and can save on structural reinforcement costs (such as not requiring additional beam and column reinforcement when renovating old buildings).
