Shortcomings of steel profiles

Each product has its shortcomings, and with the widespread use of plastic profiles, some shortcomings are also exposed. Most of the inferior profiles of China's plastic steel profiles use lead salt stabilizers, and the lead content of finished products is between 0.6% and 1.2%. Lead is a kind of substance harmful to the human body. When inferior profiles are aged, lead dust will be precipitated. After long-term exposure, the lead content in the blood will exceed the standard, and even lead poisoning. Recently introduced calcium zinc and organotin formulations have solved the product. The problem of lead, however, has not been applied on a large scale due to price reasons and immature technology.
