AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier providing 3D software design, ODM, OEM, and sample-based customization services. It reports ISO9001:2015, ISO14001, and CE certification, along with quality assurance procedures, raw-material traceability, documented complaint handling, and 100% finished-product inspection. Production-related evidence includes waterproof-coil production lines, testing equipment, inventory capability, and lead times within 15 working days in both peak and off-peak periods. However, it has no valid manufacturing contract with related subcontractors, no overseas warehouse or showroom, no SDK, no new products reported in the past year, and no overseas-service countries listed. Financial credibility and customer-case evidence are insufficient for a definitive assessment.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and provides 3D software design, ODM, and OEM services, including service to popular brands. This supports classification as a technical/design-oriented manufacturer or supplier.

CertificationsThe supplier reports CE product-compliance certification and ISO9001:2015 and ISO14001 management-system certifications. These stated certifications provide explicit evidence of compliance and management-system credentials.

After-Sales capabilityThe supplier describes a documented after-sales service system, has clear complaint-handling procedures with records, and lists debugging, maintenance, repair, training, and equipment installation services. However, it lists zero countries offering overseas services, so the evidence supports after-sales processes but not broad international coverage.

R&D capabilityThe supplier provides 3D design, ODM, and sample-based customization, indicating design and development capability. However, it reported no new products in the past year, no available SDK, and no established AI model for data-driven decision management, limiting evidence of recent or advanced innovation.

Production capacityThe supplier reports waterproof-coil production lines, tensile and asphalt testing equipment, inventory capability, 100% finished-product inspection, two quality inspectors, and lead times within 15 working days in peak and off-peak periods. Nevertheless, it lacks a valid manufacturing contract with related subcontractors; the evidence demonstrates operational capacity but also a stated contractual deficiency.

Customization capabilityCustomization from samples is explicitly offered, supported by 3D software design, ODM services, and OEM services for popular brands. These capabilities directly demonstrate the ability to accommodate customized product requirements.

Product Q&A

Q:Can the thickness of the SBS bitumen membrane be customized?

Yes, absolutely. While our standard thicknesses are 3mm, 4mm, and 5mm, we support full customization. We can manufacture thicknesses ranging from 2mm to 5mm according to your project's specific engineering requirements or local building standards. Please contact our team with your detailed specifications.

Q:Is the installation process safe and easy for workers?

Yes, our SBS membrane is designed for high installation efficiency and safety. For the torch-applied version, the bottom PE film features a special melt-indicator pattern that tells workers exactly when the bitumen is ready to bond, preventing over-heating. We also offer a self-adhesive variant that requires no open flame, making it 100% flame-free and incredibly safe for confined or high-risk spaces.

Q:Can this membrane be applied in extremely cold weather?

Yes. Thanks to the high-grade SBS (Styrene-Butadiene-Styrene) modifier and the heavy-duty polyester core, our membrane maintains excellent low-temperature flexibility down to -20 C / -25 C. It will not crack or become brittle during winter installation, ensuring a safe and reliable seal year-round.

Q:Which surface finish (PE film, Sand, or Mineral) should I choose for my project?

It depends on your application: PE Film / Fine Sand: Best for non-exposed roofing, basements, and underground projects where another layer (like concrete or gravel) will cover the membrane. Mineral Granules (Granular Surface): Best for exposed roofs. The granules protect the bitumen from UV radiation and mechanical damage, while also offering an aesthetic finish.

Q:What equipment is needed for the torch-on installation?

The basic equipment required is very standard and easy to source: a propane gas torch with a connecting hose, a gas cylinder, a pressure regulator, a cutting knife, and a heavy roller or trowel to press the seams. The straightforward process helps save on labor costs and shortens the project timeline.
