What are the application standards for hot-dip galvanized gratings?


What are the application standards for hot-dip galvanized gratings? The following editor will take you to take a look.
Through years of design work, it is found that as long as the specification selection is economical, reasonable, safe and reliable, the total cost can be reduced, and the purpose of saving steel and investment can be achieved. When selecting the type of hot-dip galvanized grating, first determine the choice of surface coating according to the conditions of use. The surface of steel grating can generally be divided into hot-dip galvanized, painted or untreated. For example, hot-dip galvanized steel gratings in petrochemical enterprises are mostly used in the open air or where there is atmospheric, medium and other corrosion. Therefore, most of them choose surface hot-dip galvanizing. The advantage of this option is that the galvanized layer is strong and corrosion-resistant, and the service life is at least 30 Years, maintenance-free.
The assembly materials of steel structure buildings are mostly designed to be easy to install and disassemble. For example, due to changes in conditions, it is easier to rebuild or dismantle them; the disassembled parts are also easy to transform. The steel grating material can be recycled and needs to be disposed of. There is very little waste. Steel structure buildings constructed with steel gratings have small cross-sections, large bays, and high headrooms, which can increase the usable area by 5%-8%3; the available land resources in my country are tight, and steel structure buildings have the advantages of land saving and energy saving, which are in line with development National policy for energy-saving and land-saving housing.
Due to the flexibility of the steel structure system connection, a variety of light-weight, high-strength and high-efficiency wall materials can be used with it, and advanced products such as energy saving, waterproofing, heat insulation, doors and windows, etc. are assembled together to realize wall reform and comprehensive sets application.
The hot-dip galvanized steel grating of steel grating manufacturers is mainly determined by the service life of the link and overview whether the zinc layer has been crushed. Specifically, it is air humidity and pH. The life span can reach 70-80 years in the dry field, 40-50 years in the warm ocean, and 20-30 years in industry. The premise is that the zinc layer on the surface is not crushed by external forces.
