Things to pay attention to when purchasing steel grating Steel grating is now widely used in many industries, such as power stations, boilers, chemical industries, etc., because it has the advantages of ventilation, anti-skid, beautiful appearance, etc. (Explanation: A favorable situation that can overwhelm the opponent), so it is also well received by trial users. So, when purchasing steel gratings, how can you choose good quality?
304 stainless steel grating production method: machine pressure welding uses a high-voltage resistance pressure welding machine. The robot automatically places the crossbars horizontally on the evenly arranged flat steel, and presses and welds the crossbars into the flat steel through powerful electric welding power and hydraulic force. , thus obtaining high-quality steel gratings with strong welding joints, extremely high stability and strength. As the name suggests, toothed steel grating is a steel grating made of toothed flat steel. In addition to the characteristics and uses of ordinary steel gratings, it also has strong anti-slip capabilities. It is especially suitable for wet and slippery places, offshore oil production platforms, etc. The serrated steel grating adopts hot-dip galvanized surface treatment, which has strong rust resistance.
This product can be used to connect the gutter cover and frame with hinges, which is anti-theft, safe and easy to open. Hot-dip galvanized steel grating, also known as hot-dip galvanized steel grating, is a grid-shaped building material made of low carbon steel flat steel and twisted square steel welded horizontally and vertically. Hot-dip galvanized steel grating has strong impact resistance, strong corrosion resistance and heavy load capacity, elegant and beautiful appearance, and has excellent performance in municipal roadbed and steel platform construction projects.
First, look at the surface steel layer. When purchasing a steel grating, you must first look at the steel layer on the surface of the steel grating. This is the most important for this kind of steel grating made of carbon (C) plain steel. Consideration, because the quality of steel grating mainly depends on the thickness of the steel layer on its surface, we all know that steel grating can generally be divided into two types, one is cold steel, the other is hot steel, hot steel The price of steel is higher than that of cold steel because its service life is longer and its corrosion resistance (meaning: decay, disappearance, erosion, etc.) is stronger. Because the steel layer on its surface can reach a thickness of 7UM, while the steel grating of cold steel has a thickness of only 1UM. Although the price is much cheaper than that of hot steel, in terms of service life, it is It is not as good as hot steel, because the thickness of the steel layer directly determines its corrosion resistance.
Second, the quality of raw materials should consider the quality gap of the specific raw materials used for steel gratings. In order to save costs, many unscrupulous manufacturers will use recycled scrap steel to produce and process flat steel instead of using carbon steel. This may cause This causes the problem of insufficient load-bearing weight, and the steel body may deform as the use time increases. This is all due to the use of scrap steel, so you must purchase it from a well-known brand manufacturer.
Third, flat steel correction (word meaning: correction level and welding level). Carefully check the flat steel correction level and welding level of the steel grating. You must know that this also has a great impact on the quality of the steel grating, such as It is said that the diagonal tolerance should be controlled within an acceptable range. Therefore, when purchasing steel gratings, you can judge from the above aspects, so that you can choose high-quality products for better convenience. use.
