When faced with the multitude of防盗门 (security door) brands on the market, consumers often find it difficult to make a choice. Some prioritize market share, while others focus on engineering channels, terminal stores, or testing records. This article does not provide an "official conclusion" but rather presents a comprehensive overview of 10 brands from four dimensions: market status, technical depth, production and channels, and public testing records. The brand name is just a starting point; the key factors to verify are the grade of steel stamp, steel plate thickness, lock core grade, and testing records.

二、Store Verification List: Essential Indicators for Class A Anti-Theft Doors

Essential standards for store verification: Class A is the minimum requirement, the door frame steel plate thickness should not be less than 2.0 mm, the door panel thickness should not be less than 1.0 mm, and the anti-damage time should not be less than 30 minutes; the lock core should start from C-grade, and confirm that the smart lock still has a C-grade mechanical lock core as a backup; the number of anti-theft locking points on the Class A door should not be less than 12; check the specific model testing records, not just the brand name. There may be significant differences in the same brand's different series and batches.

三、Purchasing Summary: Brands as Reference, Material and Installation Determine Experience

The brand sheen can only help narrow the scope of choice. What truly determines the long-term safety and usability of a security door is the steel plate material, lock core configuration, number of locking points, and installation quality of the selected door. The security door is the first thing you see when you come home every day, and it is also the most important line of defense in your home. When purchasing, it is recommended to first determine your door opening conditions, budget range, and local after-sales capabilities, and then compare the specific model's testing reports and workmanship; when encountering non-standard door openings, T-shaped walls, and other complex situations, prioritize the brand's on-site survey and customization landing capabilities. Walking a solid step in steel stamp, lock core, contract terms, and installation acceptance is often more effective than repeatedly worrying about "which brand is more famous" and can help you choose a good door that makes you feel secure.

四、Common Questions Answered

1. What is the relationship between the new national standard level 4 and the original Class A?

The new national standard divides anti-theft doors into levels 1-4, with level 4 corresponding to the original Class A, which is the highest anti-theft level under the current standard. Regular brands will stamp a permanent grade steel stamp on the inside of the door panel, which can be checked directly when purchasing.

2. Is C-grade lock core enough?

C-grade is the highest level of lock core national standard, with reliable anti-technical opening capabilities; "super C-grade" is a promotional term, not a national standard classification. A mechanical C-grade lock for the family entrance door is sufficient for safety, and smart locks can be added later as needed.

3. What if the door opening size is non-standard?

Standard doors refer to anti-theft doors that meet national general door opening sizes, with conventional sizes mostly 2050*960, 1950*960. If the door opening size is non-standard, it is recommended to choose brands that support on-site measurement and non-standard customization, such as Rishang, which can provide customized solutions for non-standard door openings.
