There are many places in cities that require the design of handrails and guardrails. When designing, the first step is to determine what materials to use, as the characteristics of the materials themselves determine the difficulty of the project, the quality of the project, the service life, and environmental protection indicators, etc. In addition to design, designers should also have a considerable understanding of common metal materials so as to better complete the design.

　　Why do many designers prefer to use stainless steel materials for the design of handrails and guardrails? The reason is nothing more than the two advantages of stainless steel. One is its good corrosion resistance, which can prevent rusting for a long time and is easy to maintain. The other important reason is that it is easy to process, has good colors and is more environmentally friendly.

　　Many designers have good relationships with material suppliers and learn about a lot of materials through them. Since certain processing capabilities are also required, understanding the construction level of the other party can also better promote the progress of the project. After all, if the construction ability is not up to par and the designer's design cannot be realized, it is undoubtedly a very regrettable thing.
