When purchasing auxiliary materials, you need to pay attention to the following points:
Quality standards: The selection of auxiliary materials should first pay attention to their quality standards. For example, in the selection of water pipes, the price of regular brand water pipes is usually 15 to 20 yuan per pipe, while water pipes that cost a few yuan per pipe are likely to be engineering materials with poor quality. The choice of cement is also very important. It is recommended to choose cement with a grade of 32.5R or 42.5R, and try to choose nationally renowned brands such as building materials, conch, and Sinoma.
Brand selection: Choosing well-known brands can ensure the quality of auxiliary materials. For example, water pipes can choose brands such as Weixing, Poly, and Jinniu; wires can choose brands such as Jindiao, Pigeon, and Yufeng; waterproof materials can choose brands such as Oriental Yuhong, Degao, and Laoyal; tile adhesives can choose brands such as Degao, Yuhong, and Nippon; gypsum boards can choose brands such as Longpai, Taishan, and Saint-Gobain.
Environmental protection standards: Environmental protection is a factor that cannot be ignored when purchasing auxiliary materials. For example, wood boards should be selected with high environmental protection standards such as ENF and F4 star standards; latex paints should be selected from brands such as Dulux, Nippon, and Sankeshu to meet national environmental protection indicators and performance requirements.
Applicable scenarios: Select appropriate auxiliary materials according to specific usage scenarios. For example, water pipes should be selected from PPR hot water pipes suitable for hot water use, with a pipe diameter of 25 and a wall thickness of more than 3.5 mm; wires should be selected according to specific power requirements. Appropriate specifications and brands.
