1、 Basic information

● in order to install more quickly and conveniently and save human resources, hot-dip galvanized guardrails and louvers are installed in the most simple assembly mode, which greatly improves the installation efficiency of guardrail works.

● compared with other railings, it has the characteristics of environmental protection. In line with modern people's pursuit of environmental protection, it also fundamentally solves the problem that buildings are not randomly polluted.

● the use of hot-dip galvanized guardrail is universal. For example, due to the environmental and climatic characteristics of coastal and humid areas, the guardrail must be free from the influence of climate, acid, alkali, humidity and heat. However, the performance characteristics of hot-dip galvanized guardrail fully meet these requirements, so that it can be applied in different fields.

In short, the excellent characteristics of zinc steel railings are based on the advantages of traditional railings in the past. Therefore, the development of zinc steel railings will be overwhelming and quickly applied to the industry of building materials railings.

2、 Technical parameters
