Qingzhou Guangyuan Greenhouse Engineering Co., Ltd. Supplier Evaluation

Executive Summary

Qingzhou Guangyuan Greenhouse Engineering Co., Ltd. is a China-based greenhouse engineering supplier located in Shandong, with a reported factory area of over 15,000㎡ and more than 30 staff. The supplier offers multiple greenhouse-related products, including single-span tunnels, multi-span PE-covered greenhouses, agricultural plastic tunnels, tomato greenhouses, and multi-span greenhouse structures, with MOQs generally ranging from 500 to 1,000 square meters. The company has Gold Supplier status for 1 year, supports Trade Assurance, and is marked as a verified supplier, which provides a basic level of platform credibility. However, its commercial track record on the platform is weak, with 0 orders, no disclosed transaction amount, no store rating, and 0 reviews in the past six months. The supplier may be suitable for buyers seeking greenhouse products with factory-backed supply capability and Trade Assurance protection, but it is less suitable for buyers requiring strong proven transaction history, mature customer feedback, or extensive quality-performance evidence.

Detailed Analysis

1. Company Strength — 20 Points

Basis

• Company name: Qingzhou Guangyuan Greenhouse Engineering Co., Ltd.
• Country: China
• Factory province: Shandong
• Factory area: 15,000+㎡
• Employees: 30+ staff
• Verified supplier: True

Elaboration

The supplier reports a factory area exceeding 15,000㎡, which indicates a meaningful physical production base for greenhouse-related structures. The employee count of more than 30 staff suggests that the company has an operational team, but the workforce size is not large compared with more mature industrial manufacturers. The verified supplier status strengthens the basic credibility of the company’s factory information, although no additional factory audit details, production capacity figures, annual output, equipment list, or formal factory management certifications are provided in the supplied data.

Scoring Rationale

The company shows evidence of a real production base and has a relatively sizable factory area. However, the staff size is moderate, and the available data does not confirm large-scale production capacity, advanced manufacturing systems, or third-party factory certifications beyond verified supplier status. Therefore, the supplier fits better into the category of a medium-sized stable factory rather than a large-scale, highly proven supply chain operator.

Final Score

15 / 20

2. Platform & Compliance Credibility — 20 Points

Basis

• Gold Supplier: True
• Gold Supplier tenure: 1 year
• Trade Assurance: True
• Verified supplier: True
• Certification / industry tags:
• Low MOQ for customization
• Response time ≤2h
• On-time delivery 100.0%

Elaboration

The supplier has basic platform credibility through Gold Supplier status and Trade Assurance support. Trade Assurance is important for procurement risk control because it provides a platform-backed transaction mechanism. The verified supplier status also adds credibility to the company profile. However, the Gold Supplier tenure is only 1 year, which means the platform operating history is still relatively short. The provided tags are operational or service-related rather than formal product certifications or industry compliance certifications. No ISO certification, CE certification, greenhouse-specific engineering certification, or finished product inspection label is provided in the supplied data.

Scoring Rationale

The supplier has the core platform trust elements: Gold Supplier status, Trade Assurance, and verified supplier status. These support a reasonable level of sourcing credibility. However, the short Gold Supplier history limits long-term platform trust, and the certification label set is not comprehensive from a compliance perspective. Because the credibility foundation is present but not mature or extensive, the score falls within the mid-range.

Final Score

15 / 20

3. Business Performance — 20 Points

Basis

• Orders in the past 6 months: 0
• Transaction amount in the past 6 months: Insufficient Data
• Store rating: Insufficient Data
• Number of reviews: 0

Elaboration

The supplier has no recorded orders in the past six months according to the provided data. No transaction value is available, and no store rating is disclosed. The review count is also 0, which means there is no visible customer feedback record to validate recent buyer satisfaction, order execution, or repeat purchasing behavior. While the supplier may still have offline business activity, such information is not included in the provided dataset and therefore cannot be considered in this assessment.

Scoring Rationale

Business performance is the weakest area in the evaluation. A 0-order record, no disclosed transaction value, no rating, and no reviews create a major gap in commercial validation. The supplier may have production capability, but the available platform data does not demonstrate recent sales traction or buyer acceptance. As a result, the score is below the standard level for stable trading suppliers.

Final Score

5 / 20

4. Service Capability — 10 Points

Basis

• Communication response time: ≤2h
• Customization-related tag: Low MOQ for customization
• Full Customization: Insufficient Data

Elaboration

The supplier’s response time is listed as within two hours, which is a positive indicator for communication efficiency. The platform tag “Low MOQ for customization” suggests some level of customization flexibility, especially for buyers requiring lower customization thresholds. However, the data does not confirm whether the supplier supports full customization, engineering customization, design customization, or project-based greenhouse configuration services. Therefore, the service capability can be considered responsive but not fully proven for complex customized procurement.

Scoring Rationale

A response time of ≤2h is commercially acceptable and indicates active communication capability. The customization-related tag supports some service flexibility, but because Full Customization is not explicitly confirmed, the supplier cannot be rated at the highest service level. The supplier is therefore assessed as having normal-to-good service capability with incomplete evidence for advanced customization.

Final Score

7 / 10

5. Delivery Performance — 10 Points

Basis

• On-time delivery rate: 100.0%

Elaboration

The supplier’s listed on-time delivery rate is 100.0%, which is a strong delivery indicator based on the available platform data. This suggests that recorded delivery performance, where measured, has met committed timelines. However, the interpretation should be considered together with the business performance data, because there were 0 orders in the past six months. The dataset does not clarify the volume or sample size behind the 100.0% on-time delivery figure.

Scoring Rationale

According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. Since the reported rate is 100.0%, the supplier receives a high delivery score. However, because the recent order count is 0, buyers should treat this metric as positive but not independently sufficient to prove delivery reliability at scale.

Final Score

10 / 10

6. Quality & Customer Feedback — 20 Points

Basis

• Store rating: Insufficient Data
• Review count: 0
• Finished Product Inspection: Insufficient Data
• Factory Verification / Verified supplier: True

Elaboration

The supplier has verified supplier status, which provides some basic confidence regarding company and factory existence. However, there is no disclosed store rating, no customer reviews, and no evidence of Finished Product Inspection in the supplied data. This creates a significant limitation in assessing actual product quality, consistency, packaging performance, installation outcomes, or after-sales satisfaction. For greenhouse products, buyer feedback and quality inspection records would normally be important procurement references, but they are not available here.

Scoring Rationale

The supplier receives limited credit for verified supplier status, but the absence of customer reviews, store rating, and finished product inspection evidence prevents a higher quality score. The quality assurance system is not sufficiently documented in the supplied data, and there is no buyer feedback to validate performance. Therefore, the score remains below the midpoint of the full quality dimension.

Final Score

8 / 20

Procurement Recommendation

Recommendation: Conditional Cooperation Recommended

Qingzhou Guangyuan Greenhouse Engineering Co., Ltd. may be considered for conditional cooperation, especially for buyers sourcing greenhouse structures who value factory presence, Trade Assurance support, verified supplier status, and responsive communication. The supplier appears more suitable for buyers willing to conduct additional due diligence before committing to larger orders.

Suitable Customer Types:
- Buyers seeking greenhouse products with MOQs of 500–1,000 square meters
- Importers or project buyers who can use Trade Assurance for transaction protection
- Customers willing to start with sample orders, pilot projects, or small-batch procurement
- Buyers prioritizing basic factory capability over proven platform sales history

Main Risk Points:
- 0 orders in the past six months
- No disclosed transaction amount
- No store rating
- 0 customer reviews
- No provided evidence of Finished Product Inspection
- Gold Supplier history is only 1 year
- Full Customization capability is not confirmed

Growth Potential:
The supplier has a credible operational base with 15,000+㎡ factory area, verified supplier status, Trade Assurance support, and a 100.0% listed on-time delivery rate. If it can build transaction history, collect customer reviews, disclose quality inspection processes, and strengthen certification visibility, its procurement attractiveness could improve significantly. For now, buyers should proceed with controlled order sizes, request technical documentation, confirm inspection procedures, and use Trade Assurance to reduce sourcing risk.
