The anti-theft door is an important line of defense for home security, and its anti-theft effect is mainly related to its material and the thickness of the door. At present, the security door we use can be roughly divided into steel-wood security door, alloy security door, stainless steel security door, copper security door, etc. Different types of security doors have certain differences in anti-theft performance. Not all doors can be called security doors. There are certain standards for security door countries. Usually, we use a door that cannot be violently opened within 15 minutes with relevant tools as a security door.
Security door level introduction
According to the level of anti-theft performance, the security door can be divided into four levels: A, B, C and D. Among them, Class A security door has the highest level of anti-theft, and D-class security door has the lowest level of anti-theft. The stainless steel security door is currently the most respected security door on the market, and it is gradually replacing the traditional security door. The stainless anti-theft door can be graded like other security doors, namely A, B, C. The C-class anti-theft door has the best anti-theft performance.
Stainless steel anti-theft is made of stainless steel, so its safety performance is greatly improved, and the service life is also improved. In particular, the thickened version of the stainless steel security door can be used as a security door for some confidential warehouses, and its anti-theft level can reach the extremely high level in the security door. However, its material has a higher price, which is generally higher than the traditional security door. In addition, the color of the stainless steel security door is generally monotonous silver, the color is too bright, it is easy to produce some stain spots or rust spots, which greatly affects its appearance.
The effect of stainless steel security door thickness on the anti-theft level
Stainless steel security doors are generally used as entrance doors. Therefore, to ensure the safety of residents, their anti-theft performance cannot be ignored. The anti-theft level of the stainless steel anti-theft door has a close relationship with its thickness. In theory, the anti-theft performance of the stainless steel anti-theft door is proportional to its thickness, that is to say, the thicker the thickness, the better the anti-theft performance. The door of the stainless steel security door is composed of the front and rear steel plates and the intermediate filling portion, so the thickness should include the total thickness, the thickness of the front steel plate and the thickness of the thick steel plate. At present, the total thickness of the stainless steel security door on the market is generally between 5 cm and 7 cm, and the thickness of the front and rear steel plates is generally 0.6 cm, 0.8 cm and 1.0 cm. In order to enhance the anti-theft ability of the stainless steel security door, the thickness of the front steel plate is generally thicker than the thickness of the rear steel plate. If the common stainless steel security door steel plate is 0.8 cm, the thickness of the rear steel plate is 0.6 cm.
Stainless steel security doors are worthy of attention when purchasing or customizing. They are mainly reflected in materials, specifications, quality, workmanship, etc. First of all, the stainless steel materials for stainless steel security doors are also rated as high or low, of which 302 and 304 stainless steel plates are in At present, there are more used stainless steel security doors; then, in the selection or customization, we must look for qualified manufacturers to prevent counterfeiting; finally, carefully observe the fineness of stainless steel security door work, and judge the quality of the door from some details. Good change.
