Introduction of Raw Material

Most filing cabinet is made of steel. Actually, it’s called cold rolled steel plate. The cold rolled steel plate is made from hot rolled steel plate, being re-rolled under crystallizing temperature. The carbon component is under 2.0%, thickness between 0.1-8.0mm. And the actual thickness and width is according to factories’ facility and market needs. Smooth and solid cold rolled steel plate is going to pass panel beating, bending, welding, pickling, phosphating and powder spray to become a steel cabinet. Raw material determines the stabilization and appearance of finished product. And the thickness goes first. Regularly, it’s separated into thick plate (0.6-0.8mm) and thin plate (0.3-0.5mm). And the final thickness will be increased by 0.1mm-0.2mm after powder coating. The thin steel plate cabinet is a product generated during vicious business competition. Technically, it can’t meet users’ actual demand. So only cabinet with bare thickness over 0.6mm can guarantee a long-term application. Anyhow, thickness is one among the factors. More important is the quality. Even plates with the same thickness differ much in quality. HUADU GROUP has been focusing on producing the best steel furniture for 20 years, only the material from big and reliable suppliers can be selected through material factory test. Moderate carbon component in the plate means moderate hardness, lower tolerance when bending, smooth when punching and assembling, finally become a nice and solid product. Some bulging plate can be found in wave shape when seeing in the distance, not qualified in appearance or stabilization even after powder spraying. Besides, the powder spraying is also an unignorable factor. At last, one can not be too addicted to thickness, quality or powder coating unilateral. Take every factor into consideration and choose wisely. Brand will not lie. HUADU GROUP, ONLY THE BEST.
