Shenzhen Double Building Materials Co., Ltd. Supplier Evaluation
Executive Summary
Shenzhen Double Building Materials Co., Ltd. is a Guangdong, China-based supplier with a reported factory area of 3,200+ sqm and 50+ staff. The company shows a relatively stable operational foundation for customized or project-oriented building material products, with listed offerings including luxury powder-coated designs, villa-related products, traditional steel structure products, and interior powder-coated steel items. Its platform credibility is strong, supported by 10 years as an Gold Supplier, Trade Assurance availability, verified supplier status, and relevant service/quality tags such as Project Solutions, Warranty Available, Finished Product Inspection, and ODM Service Available. Business performance is moderate to solid, with 50+ orders and CN¥3.7M+ transaction value over the past six months, although the review count is limited at only 5. The supplier appears suitable for buyers seeking project-based or customized building material solutions with low MOQ flexibility. Key concerns include limited customer feedback volume and insufficient data on full customization capability beyond ODM availability.

Detailed Analysis
1. Company Strength
Basis
- Factory area: 3,200+ sqm
- Employees: 50+ staff
- Location: Guangdong, China
- Verified supplier: True
Elaboration
The supplier has a defined physical production base and workforce scale. A 3,200+ sqm facility with 50+ employees suggests a small-to-medium manufacturing operation rather than a large-scale industrial supplier. The verified supplier status adds credibility to the existence and basic operational structure of the company. However, there is no additional data on production lines, annual capacity, machinery, warehouse capacity, or factory audit details.
Scoring Rationale
The company demonstrates basic and credible manufacturing capacity, supported by factory area, employee count, and supplier verification. However, the scale is not large enough to classify it as a major high-capacity supplier, and the lack of detailed production capacity data limits the assessment. It fits the profile of a smaller but operationally established factory with project-oriented supply capability.
Final Score
13 / 20
2. Platform & Compliance Credibility
Basis
- Gold Supplier: True
- Gold Supplier duration: 10 years
- Trade Assurance: True
- Verified supplier: True
- Certification / industry tags: Project solutions, Warranty available, Finished product inspection, ODM service available
Elaboration
The supplier has a strong platform credibility profile. A 10-year Gold Supplier history indicates long-term platform presence. Trade Assurance provides transaction protection, while the verified supplier status supports basic trustworthiness. The listed tags also indicate platform-recognized capabilities in project solutions, warranty support, inspection, and ODM service.
Scoring Rationale
This is one of the supplier’s strongest dimensions. The combination of long Gold Supplier tenure, Trade Assurance, verified status, and multiple relevant platform tags creates a strong compliance and credibility foundation. The only limitation is that the data does not provide details on specific third-party certifications, audit reports, or international compliance certificates.
Final Score
19 / 20
3. Business Performance
Basis
- Orders in past 6 months: 50+
- Transaction value in past 6 months: CN¥3.7M+
- Store rating: 5.0
- Reviews: 5
Elaboration
The supplier has achieved 50+ orders and CN¥3.7M+ transaction value in the last six months, showing active commercial performance on the platform. The transaction value is meaningful, especially considering that several listed products have relatively high unit prices. The store rating is excellent at 5.0, but the review base is very limited, with only 5 reviews.
Scoring Rationale
The recent order count and transaction value indicate a commercially active supplier with proven sales activity. However, the limited number of reviews weakens the reliability of the 5.0 rating as a broad customer satisfaction indicator. The business performance is stronger than a low-volume supplier but does not yet show the scale or review depth of a highly validated high-volume supplier.
Final Score
16 / 20
4. Service Capability
Basis
- Response time: ≤4h
- ODM service available: Listed
- Full Customization: Insufficient Data
Elaboration
The supplier provides a response time of within 4 hours, which is acceptable for cross-border sourcing communication, though not at the strongest level of ≤1 hour. The platform tag confirms ODM service availability, indicating some level of design or product adaptation capability. However, there is no explicit data confirming Full Customization capability.
Scoring Rationale
The supplier demonstrates reasonable service capability through acceptable response speed and ODM support. However, because Full Customization is not confirmed and the response time is not within the top-tier threshold, the service capability should be rated as moderate rather than excellent.
Final Score
7 / 10
5. Delivery Performance
Basis
- On-time delivery rate: 94.4%
Elaboration
The supplier reports a 94.4% on-time delivery rate, which is above the 90% threshold for strong delivery performance. This suggests that the supplier has generally reliable dispatch performance based on available platform data. No additional information is provided regarding average lead time, logistics methods, delayed shipment cases, or export documentation handling.
Scoring Rationale
Based strictly on the provided on-time delivery rate, the supplier qualifies for a high delivery score. The score is not the maximum because the data only covers the rate itself and does not include deeper evidence such as lead-time consistency, project delivery records, or logistics performance across different destination markets.
Final Score
9 / 10
6. Quality & Customer Feedback
Basis
- Store rating: 5.0
- Reviews: 5
- Finished Product Inspection: Listed
- Verified supplier: True
Elaboration
The supplier has a perfect 5.0 store rating and confirms Finished Product Inspection through platform tags. Verified supplier status also supports basic quality and operational credibility. However, the total number of reviews is only 5, which is too limited to fully validate long-term quality consistency across multiple buyers or project types.
Scoring Rationale
The quality indicators are positive, especially the 5.0 rating and Finished Product Inspection tag. However, customer feedback volume is low, making the rating less statistically reliable. The supplier has basic quality assurance signals, but the limited review base prevents it from being classified as a highly proven supplier from a customer feedback perspective.
Final Score
15 / 20
Total Score
79 / 100
Procurement Recommendation
Cooperation is recommended with controlled initial procurement or project-based trial orders. Shenzhen Double Building Materials Co., Ltd. appears suitable for buyers seeking building material products with ODM support, low MOQ options, project solution capability, and platform-backed transaction protection.
The supplier is best suited for small-to-medium project buyers, customized building material purchasers, villa/interior project contractors, and buyers who value Trade Assurance and verified supplier status. Its main strengths are long platform history, strong compliance credibility, acceptable factory scale, active recent transactions, and strong on-time delivery performance.
Main risks include the low number of customer reviews, insufficient data on Full Customization capability, and limited disclosed information on production capacity, machinery, international certifications, and detailed factory audit results. Growth potential is positive if the supplier can expand verified customer feedback, provide more transparent production capacity data, and strengthen documented quality assurance evidence.
