After the grilling net is processed and manufactured, it is generally
necessary to stop the appearance treatment, so that the product has the
characteristics of beautiful, rust-proof and anti-corrosion. Generally speaking,
there are two ways to handle the appearance of barbecue nets,
electro-galvanizing and polishing. Let us introduce these two processes.

Electro-galvanizing is cold plating. It uses electroplating to galvanize the surface of the barbecue net. If the process is to dip the barbecue net and the zinc block in the electrolyte, separate the positive and negative of the direct current, the product is evenly coated, and it is plated in the acid electrolyte. The zinc grilling net has a brighter appearance, and the galvanized grilling net in alkaline electrolyte has a whiter appearance, but there is no difference in quality between the two types.
This process should be applied to the surface treatment of low-carbon steel wire barbecue nets. Regarding stainless steel barbecue net products, the commonly used surface treatment method is polishing. There are three polishing methods: mechanical polishing, chemical polishing, and electrochemical polishing. Each of these three methods has its own advantages and disadvantages.
The mechanical polishing has high brightness. The disadvantages are high labor intensity, severe pollution, and their gloss cannot be shared, the gloss does not last long, and it becomes stuffy and rusty. Deep-processed wire mesh products are more suitable for processing simple parts, medium and small products.
The advantages of chemical polishing, which is a deep-processed wire mesh product, are that it requires less investment in processing equipment, can be polished, is fast, has high efficiency, and has good corrosion resistance. The disadvantages are poor brightness, gas overflow, ventilation equipment required, and difficulty in heating. This kind of silk screen deep-processed product is suitable for processing small batches of complex parts and products with low brightness requirements for small parts.
