Prison Door Manufacturer Shares Daily Maintenance Tips for Prison Doors. It's essential to understand some of the knowledge involved.

After the prison door installation is complete, remove the protective film and place the door in the outdoor environment. Dust and oil stains adhere to the door, causing it to fade (note: the color loses its vibrancy and becomes dull), and lose its fresh luster. We recommend that users clean the door regularly. The cleaning method involves mixing 70% water with 30% cleaning solution in a sprayer, evenly spraying it on the door surface, and gently wiping with a soft cloth.

Firstly, when consumers purchase prison security doors, they must verify the dealer's business qualifications to ensure the operator holds a "Prison Security Door Certificate" issued by the Public Security Bureau's defense management department. Before installing the door, check if the door opening size meets the requirements of the prison door manufacturer. If there are irregularities that need to be addressed before installation. Additionally, inspect the door for any deformation, dents, loss, or damage during transportation. If any of these issues arise, they must be addressed before installation.

Secondly, we closely monitor and inspect. Qualified prison door steel frame thickness should be greater than 2mm, door body thickness should be greater than 20mm, and the door weight should be greater than 40kg. After installation by the prison door manufacturer, the door must ensure uniform gaps between the door leaf and the frame, with no warping, tilting, or rebound defects. Upon closing, the door must be able to open freely without any resistance or noise.

Thirdly, when purchasing prison security doors, pay attention to whether the door bears the national certification standard "FAM," and you can also request the dealer to provide the national prison security door inspection report for the brand. If it is not a national inspection report, be especially attentive to whether the content is an inspection report for "prison security doors" or a "steel door" inspection report.

Prison door manufacturers differentiate between prison doors and steel doors using the correct methods, enabling consumers to identify the distinctions between the two.

When there is a metallic grinding sound when opening or closing the door, apply a small amount of lubricant to the door hinges or contact a professional repair person directly. Before installing the prison door, check if the door opening size meets the requirements of the manufacturer. If there are irregularities that need to be addressed before installation. Additionally, inspect the door for any deformation, dents, loss, or damage during transportation. If any of these are found, they must be addressed before installation. If there is excessive resistance when closing the door, apply a small amount of lubricant to the moving bolt (hook-shaped). If the key cannot be fully inserted into the lock when opening the door, first check for ice in the lock hole during winter or other foreign objects in the lock hole during other seasons. Notify us of the situation promptly.

Prison gates are a daily necessity, and maintenance is crucial. Carefully fill the cement. On one hand, ensure the frame is effectively bonded with the wall; on the other, the door fits the frame reasonably for long-term use without change. In our cold regions, preparing for winter before the arrival of winter is very important. When there's a significant temperature difference between indoors and outdoors, and when cold and warm air circulates, the lock core may become damp.

ThisReapply before winter, add two drops of antifreeze oil, and a bit of gasoline for cleaning after winter. Do not use vegetable oil as a lubricant (function: to reduce or avoid friction and wear). Normally, the lock cylinder cannot be easily opened. Insert the tip of the pen into the tube with a small amount of lead (appearance: blue and silver), aim it at the lock cylinder, and gently blow it in. Maintain lubrication. If you find it difficult to close the door, it's usually because the sloped bolt is moist and forms rust spots that are not easily visible to the naked eye. You can sand it down with a fine sandpaper or rub a little plastic from a pencil lead, which should easily resolve the issue.
