Grand Fiberglass Co., Ltd. Supplier Evaluation

Executive Summary

GRAND FIBERGLASS CO., LTD. is a China-based supplier located in Zhejiang, with a reported factory area of 19,000+ sqm and 70+ staff. The company appears to operate as a medium-scale manufacturing supplier with verified supplier status, long-standing platform presence, and Trade Assurance support. Its listed product scope is focused on drywall joint tape, flexible metal corner tape, PVC corner bead tape, and related drywall corner reinforcement products. Platform credibility is strong, supported by 24 years as a Gold Supplier and compliance-related tags such as Finished Product Inspection, Full Customization, ODM service, and Warranty available. However, recent business performance is relatively limited, with only 3 orders and CN¥67.6K+ transaction value in the past six months, plus only 1 review despite a 5.0 store rating. This supplier is more suitable for buyers seeking established platform credibility, medium-scale production, and customizable drywall accessory products, while requiring careful sample validation and order-stage quality control due to limited customer feedback data.

Detailed Analysis

1. Company Strength

Basis

• Country/Region: China, Zhejiang
• Factory area: 19,000+ sqm
• Staff size: 70+ staff
• Verified supplier: True

Elaboration

GRAND FIBERGLASS CO., LTD. has a reported factory area of over 19,000 sqm, which indicates a meaningful physical production base rather than a small trading-only operation. The employee count of 70+ staff suggests a medium-sized organization with basic operational capacity to support production, sales, and order handling. The verified supplier status further strengthens the credibility of its physical and operational presence.

Scoring Rationale

The factory size is relatively strong, but the staff count of 70+ does not indicate a very large-scale manufacturing workforce. Based on the available data, the supplier fits the profile of a medium-sized stable factory rather than a large-scale supply chain operator. The verified supplier status supports confidence in basic company strength, but there is insufficient data on annual output, production lines, machinery, or factory audit details to justify a top-tier score.

Final Score

16 / 20

2. Platform & Compliance Credibility

Basis

• Gold Supplier: True
• Gold Supplier duration: 24 years
• Trade Assurance: True
• Verification status: Verified supplier
• Certification/industry tags: Warranty available, Finished Product Inspection, Full Customization, ODM service available

Elaboration

The supplier has a very long Gold Supplier history of 24 years, which is a strong platform credibility indicator. Trade Assurance support provides an additional transaction protection mechanism for buyers. The presence of Finished Product Inspection, Full Customization, ODM service, and Warranty available tags also suggests that the supplier has completed several platform-recognized capability labels.

Scoring Rationale

This is one of the strongest areas for the supplier. A 24-year Gold Supplier record is significantly above average and indicates long-term platform continuity. Trade Assurance and verified supplier status create a credible purchasing framework. The only limitation is that the provided data does not include independent third-party certifications, detailed audit reports, or specific quality management certificates such as ISO; therefore, a perfect score is not assigned.

Final Score

19 / 20

3. Business Performance

Basis

• Orders in past 6 months: 3
• Transaction value in past 6 months: CN¥67.6K+
• Store rating: 5.0
• Number of reviews: 1

Elaboration

The supplier has recorded recent transaction activity, but the scale is limited. Three orders over six months and CN¥67.6K+ in transaction value indicate some commercial validation, but not a high-volume or highly active transaction profile. The 5.0 store rating is positive, but it is based on only 1 review, which limits the reliability of the rating as a broad customer satisfaction indicator.

Scoring Rationale

Business performance is moderate-to-low based on available transaction data. While the company has completed recent orders and generated platform transaction value, the order count and review volume are both limited. The 5.0 rating is favorable but statistically weak due to the single review. Therefore, the supplier cannot be classified as having high commercial momentum, even though the available transaction record is positive.

Final Score

11 / 20

4. Service Capability

Basis

• Communication response time: ≤2h
• Full Customization: Listed in platform tags
• ODM service available: Listed in platform tags

Elaboration

The supplier’s response time of within 2 hours suggests acceptable communication efficiency for international sourcing. The Full Customization and ODM service available tags indicate that the supplier may support customized product requirements and buyer-specific development needs within the listed product category.

Scoring Rationale

The response speed is good, though it does not meet the strongest benchmark of response within 1 hour. The presence of Full Customization and ODM service improves the service capability assessment, especially for buyers requiring private-label, specification adjustment, or project-based product adaptation. However, the data does not provide details on customization workflow, sample lead time, engineering support, or multilingual account management.

Final Score

8 / 10

5. Delivery Performance

Basis

• On-time dispatch rate: 100.0%

Elaboration

The supplier reports a 100.0% on-time dispatch rate, which is a strong delivery performance indicator. This suggests that, based on the available platform data, the supplier has met dispatch commitments for recorded orders.

Scoring Rationale

According to the scoring standard, an on-time dispatch rate above 90% qualifies for 9–10 points. Since the supplier’s reported on-time dispatch rate is 100.0%, it receives a full score in this dimension. However, this score should still be interpreted alongside the relatively low recent order count, because a small transaction base may provide limited stress testing of delivery consistency.

Final Score

10 / 10

6. Quality & Customer Feedback

Basis

• Store rating: 5.0
• Number of reviews: 1
• Finished Product Inspection: Listed in platform tags
• Verified supplier: True

Elaboration

The supplier has a perfect 5.0 store rating and includes Finished Product Inspection among its platform tags, which supports a basic quality assurance profile. Verified supplier status also contributes to confidence in supplier legitimacy. However, the review count is only 1, meaning the customer feedback base is too limited to confirm consistent quality performance across multiple buyers or order cycles.

Scoring Rationale

The quality framework appears positive due to Finished Product Inspection and verified supplier status. However, the customer feedback evidence is weak because there is only one review. A high rating based on a very small number of reviews cannot be treated the same as a high rating supported by broad customer validation. The score therefore reflects good stated quality controls but limited external customer feedback depth.

Final Score

15 / 20

Total Score

79 / 100

Procurement Recommendation

GRAND FIBERGLASS CO., LTD. is recommended for conditional cooperation, especially for buyers seeking drywall tape, metal corner tape, PVC corner bead tape, and related construction finishing materials from a platform-established Chinese supplier.

The supplier is suitable for: - Buyers prioritizing long-term platform credibility and Trade Assurance protection - Small to medium importers seeking drywall accessory products - Buyers requiring customization or ODM support within the listed product categories - Procurement teams willing to start with sample orders or controlled trial orders

Main risk points: - Recent transaction activity is limited, with only 3 orders in the past 6 months - Customer feedback is insufficient, with only 1 review despite a 5.0 rating - No detailed production capacity, machinery, annual output, or third-party quality certification data was provided - Quality consistency should be validated through samples, product inspection, and clear specifications before bulk purchasing

Growth potential: The supplier has strong platform credibility, a sizable factory area, verified supplier status, and customization-related service tags. If it can increase order volume, collect more customer reviews, and provide more detailed factory or quality documentation, its procurement attractiveness would improve significantly. Overall, this supplier is a credible medium-scale candidate, but buyers should apply standard supplier qualification steps before placing large-volume orders.
