The **Rishang Security Door** has gained a strong reputation among users in Beijing and Tianjin. In fact, it's often said that for every three Qi security doors sold in Beijing, two Rishang security doors are sold instead. This popularity is no accident—users love the **Sun Security Door** for its exceptional quality, durability, and safety features. Let’s take a closer look at what makes Rishang anti-theft doors stand out.
One of the key strengths of Rishang anti-theft doors lies in their **door frame design**. The door frame is crafted from high-quality cold-rolled steel plates, formed through a roll-forming process. With a thickness of up to 2.0mm for both the door frame and inner cavity, this construction ensures excellent resistance to tampering, offering unmatched stability and security.
Another standout feature is the **high-strength adjustable alloy hinge** used in Rishang doors. These hinges are designed to allow the door to remain at any angle when opened, preventing it from slamming shut or requiring extra effort to open. The hinges are thick, smooth, and coated with a durable layer that resists rust and wear, making them highly reliable over time.
When it comes to **surface treatment**, Rishang doors go through an eight-step process: phosphating film, primer, printing, spraying, wood grain finishing, topcoat, secondary phosphating film, and sealing. This meticulous process not only enhances the aesthetic appeal but also extends the lifespan of the door. The finish is resistant to fading, and the steel plate is less prone to rust, ensuring long-term performance and visual appeal.
The **door leaf** of Rishang anti-theft doors is made using one-time forming and embossing technology on high-quality cold-rolled steel. This ensures a beautiful surface pattern without compromising the door’s security. The door leaf also undergoes the same eight-step surface treatment, and the internal structure includes reinforced keels or even steel grille dragon skeletons in premium models, significantly boosting strength and anti-theft performance.
Inside the door, materials like fireproof rock wool and perlite are used for insulation and soundproofing, adding to the door’s overall functionality. This combination of fire protection, sound reduction, and thermal insulation makes Rishang doors a top choice for home security.
For locking mechanisms, Rishang uses **anti-theft locks** from reputable brands such as Bao Dean and Zhongheng. These locks are designed to resist picking, drilling, and forced entry. They prevent unauthorized access by ensuring the lock remains secure even under pressure, with features that stop prying tools from entering the lock mechanism.
Additionally, Rishang doors come with **reinforced side lock points**, using a three-position machine-type anti-theft lock approved by the Ministry of Public Security. This design increases resistance to forced entry, providing added peace of mind. The internal insurance system ensures the lock remains secure while remaining user-friendly.
The **double buckle** design of Rishang doors uses environmentally friendly technology and high-precision CNC equipment to create a stronger, more seamless connection between the door and frame. This ensures better density and structural integrity, enhancing the overall security of the door.
In summary, the **Rishang Security Door** offers a perfect blend of style, strength, and security. Whether you're looking for a reliable anti-theft solution for your home or business, Rishang delivers on all fronts.
