Points To Note When Purchasing Galvanized Steel Grating
When buying galvanized steel gratings, it is important to understand that galvanized steel gratings are now widely used in many industries, such as power stations, boilers, chemical industries and other general industries. Galvanized steel gratings are ventilated, light-transmissive, non-slip, and have strong bearing capacity. They are beautiful and durable, easy to clean, easy to install and other advantages. As a new material and new product, steel grating is being used more and more widely, and its superior performance and the good cost performance shows its application prospects. Because of its ventilation, non-slip, beautiful and other advantages, it has also been praised by consumers.
So, when choosing galvanized steel grating, how to choose good quality? Let us learn.
First, when buying a galvanized steel grating, you must first look at the steel layer on the surface of the galvanized steel grating. This is the most important consideration for the galvanized steel grating made of carbon steel. Since the quality of galvanized steel grating mainly depends on the thickness of its surface steel layer, we all know that galvanized steel grating can be divided into cold galvanized and hot-dip galvanized. The price of hot-dip galvanized is higher than that of cold galvanized. It has a long service life and also has strong corrosion resistance. Because the thickness of the surface steel layer can reach 7um, the surface steel thickness of cold galvanized steel grating is only 1um. Although the price is much cheaper than hot steel, it is not as good as hot-dip galvanizing in terms of service life, because the thickness of the steel layer directly determines its corrosion resistance.
Secondly, the quality of raw materials should take into account the quality gap of the screen when using specific raw materials. In order to save costs, many undesirable steel gratings manufacturers use recycled scrap to produce flat steel instead of carbon steel. This may cause the problem of insufficient load bearing, and the steel body may be deformed as the use time increases. All of these are caused by the use of scrap steel. Therefore, we must find a reputable brand manufacturer to purchase.
Thirdly, the flat steel correction level and welding level were carefully inspected. The flat steel correction level and the welding level of the mesh plate also have a great influence on the quality of the mesh plate. The flat steel correction level and welding level also have a great influence on the quality of the stencil, and also have a great influence on the quality of the stencil. For example, the diagonal tolerance should be controlled within an acceptable range. Therefore, when buying galvanized steel grating, you can judge from the above aspects. Only in this way can we purchase high-quality products for better use.
