How do you ensure product quality before shipment?

We conduct 3-stage inspections: raw material check, in-production quality control, and final pre-shipment inspection. All products come with certificates, installation guides, and packing lists, meeting GB/T 14436 quality requirements.

What after-sales service do you offer?

We provide 24/7 technical support, professional installation guidance, and a dedicated team for damage claims. We also assist with tax refund document preparation within 30 days after customs clearance.

What makes your push-pull/inward-opening windows different from traditional ones?

Our system windows feature multi-chamber profiles, PA66-GF25 thermal breaks, and multi-channel sealing. Push-pull models save space with smooth sliding; double inward-opening windows enable safe indoor cleaning for high-rises, outperforming traditional windows in insulation and security.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with stated manufacturing, export, service, quality-control, R&D, and financial information. It offers 3D design, ODM, OEM, and multiple customization modes, and reports an export-sales share of 41%–50%. Manufacturing resources include cutting, drilling, machining, compound, and other equipment, while finished products are checked by packing staff. Service strengths include inventory capability, participation in the 2025DCDE offline trade show, documented corrective/preventive-action and complaint-handling procedures, and quality assurance. Limitations include no valid manufacturing-capacity contract with affiliated subcontractors, no overseas warehouse, showroom, agent, or branch, no SDK, and no new products in the past year. Certification evidence and specific customer cases are not provided.

Supplier typeThe supplier is explicitly classified as a combined company. The same record describes its offering as covering manufacturing, export trade, service, quality control, R&D, and financial capacity, indicating a broad operational scope rather than a narrowly defined trading-only profile.

After-Sales capabilityThe supplier has inventory service capability, documented complaint-handling procedures with implementation records, and corrective/preventive-action procedures. However, it has no overseas warehouse, showroom, agent, or branch; its stated service network covers the country and some overseas regions, but the overseas service structure is not specified.

Production capacityThe supplier reports inventory capability and lists substantial production equipment, including machining, cutting, drilling, compound, and double-headed saw equipment. A deficiency is that no valid contract exists between the factory and affiliated subcontractors, creating a documented capacity-governance gap.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also offers 3D design and ODM services. These records provide direct evidence of broad customization capability.

Client casesEvidence of market or customer experience includes OEM service for popular brands, participation in the 2025DCDE offline trade show, nearly 300 specialty stores and distributors, and export sales representing 41%–50% of total sales. Specific named customer cases, project descriptions, or verifiable brand references are not supplied.

Product Q&A

Q:What core packaging protections do your windows/doors offer?

We use a 4-layer system: nylon corner guards, full EPE wrapping, waterproof cartons, and ISPM 15 wooden frames. Hardware is sealed separately; long profiles have anti-deformation supports, glass edges use custom sponges, and all parts get residue-free degradable film. Wood frames are IPPC heat-treated, fully compliant with EU 94/62/EC.

Q:What are your logistics and transit time standards?

95% of shipments use sea freight (dry containers; long items in open-top containers). Transit: 35-40 days to EU, 7-10 days to Southeast Asia, with full real-time tracking. We add VCI anti-rust treatment and desiccants for sea transport, and steel belt reinforcement for land transport.

Q:Do your products support personalized customization?

Yes. All windows, doors, and sunrooms support full customization, including size, color, glass type (hollow/Low-E/4SG), hardware, and track design, tailored to your project and regional climate needs.

Q:What are the key performance ratings of your system windows/doors?

Our products achieve Grade 6 thermal insulation, Grade 9 wind pressure resistance, Grade 5 water tightness, Grade 7 air tightness, and Grade 4 sound insulation, meeting national and international building standards.

Q:What payment terms do you accept for international orders?

We support flexible terms including 30% T/T deposit + 70% balance before shipment, L/C at sight, and other secure international payment methods, tailored to your project scale and cooperation needs.
