Aluminum grilles are widely used in fields such as building decoration, industrial platforms, and municipal facilities due to their lightweight, high strength, and ease of processing. However, untreated aluminum surfaces are prone to oxidation, which affects their appearance and durability. Therefore, surface treatment technology has become a key link in improving the performance of aluminum grilles. The current mainstream treatment processes can be divided into anti-corrosion protection, decoration and beautification, and functional enhancement, each with its unique process principles and applicable scenarios. ​ Anodizing treatment is one of the commonly used anti-corrosion techniques for aluminum grilles. By placing an aluminum grid in an electrolytic cell as an anode, a dense

As a widely used basic component in industrial and municipal engineering, the service life of steel grating directly affects the safety and economy of the project. Unlike ordinary metal products, the lifespan of steel grating panels is not a fixed value, but is influenced by multiple factors such as material selection, surface treatment process, usage environment, and maintenance methods, with a large range of intervals. ​ Material is the core factor determining the lifespan of steel grating panels. Although Q235 carbon steel grating plate has a lower cost, it is prone to oxidation and corrosion in humid or corrosive environments. Without special treatment, its outdoor use duration in rainy areas

Steel grating, as an open plate steel component that combines load-bearing flat steel and horizontal bars at a specific distance and is fixed by welding or locking, occupies an indispensable position in many industries due to its unique structure and excellent performance. Its wide application almost covers various fields such as industry, municipal, transportation, etc. ​ In the industrial field, the figure of steel grating can be seen everywhere. In mechanical manufacturing factories, steel grilles are often laid on large equipment operation platforms. Operators can safely and conveniently carry out equipment debugging and maintenance work, and its high load-bearing capacity can easily cope with equipment operation vibrations and personnel activity

Stainless steel grating, as a metal component with both load-bearing and filtering functions, is widely used in municipal, chemical, construction and other fields. Its classification needs to be comprehensively divided based on core elements such as material characteristics, structural design, application scenarios and processing technology. From the perspective of material models, different materials directly determine the corrosion resistance and service life of the grille. Among the mainstream categories, 304 stainless steel grille contains chromium and nickel elements, with basic acid and alkali resistance, suitable for wet but non corrosive domestic sewage treatment plants, indoor drainage ditch covers and other scenarios. It is currently the most widely used and cost-effective category
