What is the breaking strength of the gypsum board?

The breaking strength is 1130N, which is considered first-class and significantly exceeds the national standard requirement of not less than 176N.

How does the board handle humidity and mould?

It balances humidity by absorbing or releasing moisture and offers great performance in mould-proofing and anti-termite protection.

What is the nail holding ability of the board?

The nail holding ability is 34N/mm, allowing nails to be held steady and enabling repeated nailing in the same location.

AI-Powered supplier vetting

SummaryGuangzhou Guanhailou Building Materials Co., Ltd. is identified as a Chinese manufacturer/factory and limited company offering gypsum lighting fixtures, although another record classifies it as a trading company. The supplier reports OEM service for well-known brands, broad customization options, a production area of approximately 40,000 square meters, CNC engraving and 3D-printing equipment, 6–10 years of R&D engineer experience, 11–20 quality-control staff, and ISO 9001 certification. However, the available information states that no SDK is available, raw-material and quality-control traceability statuses are unknown, and quality-control testing equipment is recorded as zero. Customer complaint handling and corrective/preventive actions have no written procedures or records. Financial records are only identified by years rather than substantive figures, and no customer cases are provided. The audit record lists TUV Rheinland, but its stated validity period ended on 2024-11-28.

CertificationsThe supplier reports ISO 9001 certification. A TUV Rheinland audit record exists for the primary product, gypsum lighting fixtures, but the listed report validity ended on 2024-11-28; no current certification validity is provided.

After-Sales capabilityThe supplier has no written procedures or records for effectively handling customer complaints, and it also lacks written corrective and preventive action procedures or records. These are explicit deficiencies in documented after-sales and service-response mechanisms.

R&D capabilityThe supplier describes innovation and creative R&D focused on architectural art, new materials, CNC engraving, and 3D printing, and reports 6–10 years of total R&D engineer experience. However, it explicitly states that no SDK is available, so innovation capability is supported in physical product development but not in SDK provision.

Production capacityThe supplier reports an approximately 40,000-square-meter production area, advanced CNC engraving and 3D-printing equipment, smart production lines, and 11–20 quality-control staff. Nevertheless, quality-control testing equipment is recorded as zero, which is an explicit production-quality-control deficiency despite the stated manufacturing scale.

Customization capabilityThe supplier offers customization from designs, full customization, customization from samples, flexible customization, and minor customization. It also states that it provides OEM services for well-known brands, giving explicit evidence of broad customization and OEM capability.
