Look at the glass
1 See if the glass is transparent, with no impurities, bubbles, and other defects.
Analysis: Impurities in the production of glass materials or defects in the process will cause defects such as specks and bubbles in the glass, reducing the hardness and strength of the glass.
2 See if there is 3c mark certification on the original glass.
Analysis: 3c certification is the abbreviation of China's compulsory product certification, shower products can not be sold without this logo
3 look completely tempered glass debris model
Analysis: According to the national standard, the safe breaking capacity of each 50*50mm area of ​​tempered glass should reach 40 or more.
2. Look at the profiles
1 Look at the hardness of aluminum
Analysis: The qualified aluminum thickness of the shower room is more than 1.2mm, and it takes more than 1.5mm to walk on the rail glass. The hardness of aluminum can be tested by hand-pressing aluminum frames. Aluminum materials with a hardness of 13 degrees or more are difficult for adults to deform by hand.
Brief analysis: aluminum shower room often need to support the weight of tens of kilograms or even hundreds of kilograms of glass, if the hardness and thickness can not be, shower service life will be very short, all aluminum hardness and thickness are important assessment indicators.
2 See if the surface of the aluminum is smooth, with or without chromatic aberration, trachoma, and profile finish.
Analysis: When used aluminum scrap material is processed, the smoothness of the surface treatment is not enough, there will be obvious color difference and trachoma, and the special profile of the smoothness is dark.
