How to Choose a High-Quality Security Door for Your Home

The country has strict production requirements for anti-theft doors, categorizing them into four safety levels based on anti-damage time: Grade A, B, C, and D. Grade A must withstand for at least 30 minutes, Grade B for at least 15 minutes, Grade C for at least 10 minutes, and Grade D for at least 6 minutes.

Currently, the production technology for anti-theft doors is highly mature. There are slight differences in the quality of anti-theft doors from various brands, which do not affect their functionality. The lifespan typically exceeds ten years, with minimal need for after-sales maintenance. Based on this understanding, Dafusi believes that when families choose anti-theft doors, they should focus on:

Product styles, including appearance, door color, door flatness, switch flexibility, and lock fittings, should align with the home's interior design style and personal preferences.

2. Product Pricing includes on-site measurement labor costs, anti-theft door production costs, transportation and installation costs, as well as after-sales service costs. Prices vary significantly among manufacturers, primarily due to brand premiums, with actual cost differences being relatively small.

3. The door weight, the steel plate thickness of a qualified anti-theft door frame should be at least 1.5mm, the door leaf steel plate thickness at least 0.8mm, and the door weight generally above 40kg.

Fire-resistant feature: With the increase in high-rise buildings, fire accidents occur frequently. Families should opt for fire-resistant and anti-theft doors that have fire-resistant features. In the event of a fire, they can effectively block the spread of flames, thus gaining time for rescue operations.
