stainless steel anti-theft doors are made of stainless steel materials. Because of their strong anti-theft performance, durability, diverse styles, beauty and other advantages, stainless steel anti-theft doors are favored by more and more consumers. Stainless steel anti-theft doors are also often used as entry doors. So, what should consumers pay attention to when buying stainless steel security doors

first, pay attention to the filler

the stainless steel anti-theft door is made of paper, which is a little incredible. Some stainless steel anti-theft doors use steel plates on the surface, but the filler of the interlayer is filled with paper. Originally, the State stipulated that paper can be used as filler, but this paper needs to be honeycomb paper. But now there are some manufacturers in the market who use ordinary paper case as filler. Although it is possible to use honeycomb paper, it is generally only used for low-end doors, because it is neither sound insulation nor heat preservation. The standard filler is foaming agent, which can keep heat and sound insulation. The disadvantage is that the fire prevention performance is poor, but it can prevent theft. The better one is slag cotton

second, pay attention to whether to renovate

a trap to avoid when buying stainless steel anti-theft doors is that some small workshops will recycle old stainless steel anti-theft doors and then renovate them before selling them. To check whether the old door is renovated, you can pay attention to the turnkey process. In general, the packaging of the new stainless steel anti-theft door is intact. The installer packs the key in front of the customer. The key should be in the packaging, and the packaging of the key should be complete. The lock core should be installed in front of the customer, and then the key should be handed over to the customer. But if the package of the door itself is damaged, and the key is in the worker's pocket, it may be a renovation of the door

third, pay attention to the thickness of the plate

it is understood that the stainless steel anti-theft doors on the market are made of steel plates from the surface, but some manufacturers start with steel plates. Moreover, since ordinary consumers can't distinguish between good and bad steel plates, it's more hidden to start an article

one is to make an article on the thickness of steel plate. According to national regulations, the steel plate thickness of stainless steel anti-theft doors should be more than 1mm, but the thickness of anti-theft doors made by some small workshops can't be reached at all. Some are as thin as snowflake plates made of chimneys, which loses the meaning of anti-theft, and can be opened with a hard thing

the second is to replace cold-rolled sheet with hot-rolled sheet. The steel plate of the security door should be cold-rolled. Because cold-rolled sheet has good extensibility and toughness, but the price is expensive, some manufacturers use hot-rolled sheet to replace it in order to save cost. A good stainless steel anti-theft door steel plate should also be galvanized or phosphated inside, not just painted on the surface, so that the steel plate is not easy to be corroded
