A lot of decoration companies say to the owners who choose half a package, the main materials are bought by themselves, and the accessories are suitable for us to provide. Then the question comes, what are the main materials? What are the accessories? Are you really clear? Let's learn together with Xiao Bian. 
The main material refers to floors, tiles, doors, integrated ceilings, sliding doors, kitchen hoods, hardware appliances, bathroom toilets, showers, living room sofas, lamps, etc. The main materials are ever-changing and varied. But these things have a common characteristic, that is, they do not need to be processed at the scene. We can install them when we buy them. These things are the main materials. The main material advises you to buy it yourself, so that the space you choose is very large, the size of things, and the price level is also flexible. 
Excipients are the materials to be used during the construction of our masters. There will be many types of jobs. For example: the electric wires used by the master of hydropower construction (2.5m2, 4m2), PPR water supply pipes, PVC water pipes, threading pipes, knuckles, elbows, and wires are too many. Masters of bricklayer construction use the most cement (32.5), sand (gritty, fine sand), red brick, aerated block, SBC waterproofing membrane, waterproof glue, and so on. There are many woodworking masters and paint masters who don’t list them one by one. These are all accessories that are suitable for decoration companies. What is the specific reason? 
The main material is produced by various manufacturers. After you purchase, the manufacturer provides warranty, so it is very safe in service. Since the main materials of each household are different, we have no way to concentrate on procurement. In terms of price, you have little to buy from me. However, the accessories are not the same. The accessories used in each household are almost the same, only the number of questions. Therefore, we have a fixed supplier, and we strictly control the quality, to ensure that each household uses the same high quality products, the master can only strictly keep the same. 
If the accessories are provided by the owner, it is likely that the result will be a product with uneven quality. The master uses this today, and tomorrow will use it. The day after tomorrow he will not know which one to use. Is the quality of the master's work the same? There is a more serious problem, that is, the warranty - the decoration company can not provide the warranty for the material you bought. In the same way, with such materials, we can't guarantee the quality of our work. Therefore, if problems arise in the future, it is very troublesome. This is why many decoration companies do not make clear packages.
