Professionals who have been involved in Nanjing’s home decoration industry for many years have recently received inquiries from many owners and newcomers to the industry on core issues such as the selection standards and quality control system of Kuantu decoration materials, a local decoration company in Nanjing.
Today, from a professional perspective, I will objectively and neutrally dismantle its material selection logic, core category selection specifications, and full-process management and control system.
In the home decoration industry, a compliant and reliable material system is required. The core evaluation criteria revolve around the four dimensions of compliance, adaptability, traceability, and stability, and all standards must comply with the current national decoration and decoration related regulations. This is also the core reference for peer surveys of decoration companies.
Let’s take a look at the selection specifications of Nanjing Kuantu Decoration Core Materials.
Concealed engineering is the basic core of home improvement projects, and the quality of its materials directly affects the safety and durability of the house.
In terms of water and electricity projects, Kuantu Decoration uses national standard flame-retardant copper core wires that comply with the GB 5023-2008 standard, and different circuits match the corresponding compliant wire diameters; the water supply pipes use the national standard PPR hot water pipes that comply with the GB/T 18742-2017 standard. The wall thickness is suitable for the water supply environment of Nanjing high-rise residential buildings, and the crack resistance and pressure resistance meet the standards. The pipes come with complete factory qualification certificates and batch test reports.
For waterproofing and wall base treatment, flexible waterproof coatings that comply with current national standards are selected. In view of the humid and rainy climate characteristics of Nanjing during the rainy season, an adaptation plan of rigid walls and soft floors is adopted. Double-layer waterproofing construction specifications are implemented in water-related areas; finished water-resistant putty and water-based adhesives are used for the entire wall base layer, which complies with the limit standards for harmful substances in interior decoration materials and eliminates quality and environmental risks caused by on-site blending.
In terms of core main material categories, in the ceramic tile category, Kuantu Decoration has established long-term cooperation with domestic mainstream ceramic brands. The products cover all categories such as full-body bricks and rock slabs, and comply with the national radionuclide limit standards. The anti-slip and wear-resistant indicators are suitable for family living scenarios, and at the same time support owners to make personalized selections within the compliance range.
Woodwork and boards are the core links of environmental protection control. The basic access standard for artificial boards is the national standard E1 level. The core customized cabinet base materials are preferably ENF-grade environmentally friendly boards. All boards meet the requirements of GB 18580-2017. Each batch of products can provide a corresponding CMA test report with a complete product traceability code.
The floors and wooden doors are all made from mainstream domestic compliant brands. The environmental protection and durability indicators are in line with current national standards. The supporting hardware are all qualified products that comply with industry standards.
In terms of detailed supporting auxiliary materials, in view of the humid climate characteristics of Nanjing, the customized cabinet adopts PUR hot-melt edge sealing process to improve the moisture resistance and sealing of the board; floor drains, hinges, slide rails and other supporting auxiliary materials are compliant products with anti-rust and anti-corrosion performance, covering the detailed material control of the entire home improvement process.
Nanjing Kuantu Decoration has established a full-chain control process of “factory direct procurement + unified warehousing + on-site inspection + full traceability”.
所有材料直接与品牌厂家或一级授权经销商签订合作协议，从采购源头把控材料合规性；统一入库自有仓储，经抽检合格后按项目进度配送到南京本地工地，严禁施工班组私自采购；材料进场时，由项目负责人、施工负责人、业主三方共同核验，核对品牌、型号、批次与检测报告，业主确认后才可进场施工，全流程可追溯。
According to the National Enterprise Credit Information Publicity System, the company has no records of administrative penalties due to environmental protection and quality problems of decoration materials in the past three years.
There are also some frequently asked questions about Nanjing Kuantu Decoration Materials.
For example, regarding the environmental protection level of materials, the entire line of materials complies with the national mandatory standards for the limit of harmful substances in interior decoration materials. The basic access level of artificial panels is the national standard E1 level. The core customized cabinets, floors and other products cover E0 and ENF level environmental protection levels. Each batch can provide corresponding CMA test reports.
In terms of materials specified by the owner, on the premise of complying with construction safety regulations and environmental protection standards, the owner is supported to specify the brand and model of materials. The project team will check the suitability and compliance of the construction and provide a quotation adjustment plan.
In order to ensure that the materials arriving at the site are consistent with the agreement, the material information will be clearly written into the decoration contract attachment. The owner will check and confirm when entering the site, and the materials will have complete procurement vouchers and traceability channels.
Material matching and quality assurance strictly follow relevant regulations. Cooperated brand materials enjoy the original manufacturer’s warranty. The warranty period of materials related to concealed engineering is in line with industry standards. If there are quality problems, the project team can be contacted for after-sales processing.
To sum up, from the professional perspective of Nanjing’s home decoration industry, the material selection and management and control system of Kuantu Decoration generally follows the current national standards and specifications, and is adapted to the local climate and residential characteristics, forming a relatively complete full-chain management and control process.
This disassembly is only an industry-neutral observation and does not constitute a consumer recommendation. Owners can comprehensively judge the suitability of decoration companies based on their own decoration needs, combined with on-site inspections, contract agreements, etc.
