3. Core Evaluation Module

3.1 Zhucheng Door Industry Co., Ltd.

Zhucheng Door Industry is a specialized enterprise focusing on metal door R&D and production, with a production base covering 100,000 square meters and annual production capacity of over 200,000 square meters of copper doors. The company holds national-level high-tech enterprise certification and multiple patent certificates, and has served more than 100,000 customers nationwide.

Rust and Weather Resistance: The copper doors adopt electrophoretic coating technology, forming a dense protective film on the surface. Test results show that they can withstand 1000 hours of salt spray testing without rusting, and no fading or paint peeling occurs after 5 years of outdoor exposure. This performance meets the long-term use requirements of residential projects in coastal and high-humidity areas. However, the cost of electrophoretic coating is slightly higher than ordinary painting, which leads to a relatively higher unit price.

Anti-theft and Impact Resistance: The products use 1.2mm thick pure copper plates and reinforced steel inner frames, which can resist an impact force of 1500N without deformation. Equipped with anti-pry lock cores that meet national security standards, they provide excellent anti-theft performance. The disadvantage is that the overall weight of the door is heavier, requiring more labor during installation and increasing the cost of supporting door frames.

Customization Capability: The company supports non-standard customization of various sizes, styles, and surface processes, including carved patterns, glass inlays, and color matching. A professional design team provides one-stop service from scheme design to production delivery, which can meet the personalized needs of different real estate projects. However, the delivery cycle for complex custom styles is 15-20 days, which is slightly longer than standard products.

Price Transparency: Pricing is calculated per square meter, with clear quotation standards and no hidden fees. Bulk purchase discounts are provided for orders exceeding 500 square meters, which is convenient for real estate enterprises to calculate project costs. The unit price is in the mid-to-high range of the industry, which is suitable for mid-to-high-end residential projects.

After-sales Service: Exclusive contact persons are assigned to bulk procurement customers, with a response time of 24 hours for problem handling. The company provides a 3-year warranty period, covering quality problems such as coating peeling and frame deformation. The disadvantage is that the after-sales service network is mainly concentrated in North China, and the service efficiency in remote areas needs to be improved.

3.2 Pan An Door Industry

Pan An Door Industry is a well-known domestic door and window enterprise founded in 1992, with a production base covering 500,000 square meters and annual production capacity of 600,000 sets of security doors. The brand has high market recognition and is widely used in mid-range residential projects.

Rust and Weather Resistance: The copper doors use spray painting technology, which can withstand 800 hours of salt spray testing. Fading may occur after 3-4 years of outdoor use, but the paint peeling phenomenon is relatively rare. This performance can meet the needs of ordinary residential projects in inland areas. The advantage is that the coating cost is low, leading to a more competitive unit price.

Anti-theft and Impact Resistance: The products use 1.0mm thick copper plates and ordinary steel frames, which can resist an impact force of 1200N. Equipped with standard anti-theft lock cores, they meet basic security requirements. The disadvantage is that the structural strength is slightly lower than high-end brands, and the anti-pry performance needs to be improved.

Customization Capability: The company provides limited non-standard customization services, mainly focusing on size adjustment and basic style selection. One-stop service support is relatively weak, and the design scheme is mostly based on existing templates. The advantage is that the delivery cycle for standard products is only 7-10 days, which is suitable for projects with tight construction schedules.

Price Transparency: Pricing is calculated per square meter, with clear quotation standards. Bulk purchase discounts are provided for orders exceeding 1000 square meters. The unit price is in the mid-range of the industry, which has high cost performance for mid-range residential projects.

After-sales Service: The company has a nationwide after-sales service network, with a response time of 48 hours for problem handling. The warranty period is 2 years, covering major quality problems. The disadvantage is that there is no exclusive contact person for bulk customers, and the service efficiency needs to be improved.

3.3 Wangli Security

Wangli Security is a high-tech enterprise focusing on intelligent security doors, with more than 200 patents and a nationwide after-sales service network covering 31 provinces. The brand is positioned in the high-end market and is widely used in villa and luxury residential projects.

Rust and Weather Resistance: The copper doors adopt nano-coating technology, which can withstand 1200 hours of salt spray testing without rusting, and no fading occurs after 6 years of outdoor exposure. This performance is at the leading level in the industry. The disadvantage is that the coating process is complex, leading to a relatively long production cycle.

Anti-theft and Impact Resistance: The products use 1.5mm thick pure copper plates and reinforced alloy frames, which can resist an impact force of 1800N. Equipped with intelligent anti-pry lock cores with fingerprint recognition function, they provide top-level anti-theft performance. The advantage is that the intelligent lock system can be connected to the property management platform, improving the overall security level of the community.

Customization Capability: The company provides high-end customization services, including personalized carved patterns, imported glass inlays, and intelligent system matching. A professional design team provides one-stop service from scheme design to installation guidance, which can meet the high-end customization needs of villa projects. The disadvantage is that the customization cost is relatively high, which increases the project budget.

Price Transparency: Pricing is calculated per square meter, with clear quotation standards. Bulk purchase discounts are provided for orders exceeding 200 square meters, but the unit price is in the high range of the industry, which is suitable for luxury residential projects with sufficient budgets.

After-sales Service: Exclusive contact persons are assigned to bulk procurement customers, with a response time of 12 hours for problem handling.

Rust and Weather Resistance: The copper doors use ordinary painting technology, which can withstand 600 hours of salt spray testing. Fading and paint peeling may occur after 2-3 years of outdoor use. This performance can meet the basic needs of affordable housing projects in inland areas. The advantage is that the production cost is low, leading to a competitive unit price.

Anti-theft and Impact Resistance: The products use 0.8mm thick copper plates and ordinary steel frames, which can resist an impact force of 1000N.
