Top 10 Questions B2B Buyers Should Ask Before Choosing an Aluminum Window, Door & Cabinet Manufacturer in China
For developers, builders, contractors, importers, and project owners sourcing aluminum windows, doors, and built-in cabinets, finding the right factory partner is essential for long-term success. Working directly with a qualified Chinese manufacturer offers better pricing, customized solutions, and faster delivery—but only if you ask the right questions.
Here are 10 key questions every B2B buyer should ask when evaluating an aluminum window, door, and cabinet factory in China:
1. Are You a Direct Manufacturer Specializing in Aluminum Windows, Doors, and Cabinets?
Many suppliers on B2B platforms are trading companies with no production capability. Ask if the company owns its own factory, especially one dedicated to aluminum window systems, door structures, and customized cabinetry.
✅ ROLAY is a factory-direct manufacturer with over 15 years of experience. Our 20,000㎡ facility integrates aluminum extrusion, CNC fabrication, powder coating, and final assembly of windows, doors, and full-house cabinet systems.

2. What Types of Projects Have You Supplied? Can You Share Real Cases?
Whether you're working on high-rise apartments, villas, hotels, or commercial spaces, your supplier should have relevant experience.
✅ We have supplied aluminum systems for projects in Southeast Asia, Australia, and the Middle East, including private villas, residential buildings, and hospitality interiors. Ask us for detailed project references.

3. What Testing and Certifications Do Your Products Meet?
Aluminum doors and windows must meet performance standards such as wind resistance, water tightness, thermal insulation, and soundproofing. For cabinets, material safety and durability are key.
✅ Our products are CE-certified and tested for insulation, air tightness, and waterproofing. We use eco-friendly materials for aluminum cabinetry suitable for modern kitchen, wardrobe, and bathroom applications.

4. Can I Audit Your Factory or Take a Virtual Tour?
Before long-term cooperation, many buyers want to confirm the factory’s production capacity and workflow. A professional manufacturer should be open to factory visits or virtual inspections.
✅ We welcome overseas clients to audit our factory or take a real-time virtual tour via video call. Our VR showroom offers a 360° view of our product gallery and workshops.

5. How Do You Handle Product Customization for Projects?
Custom sizing, finishes, hardware, and installation compatibility are critical in architectural projects. Ensure the supplier can handle tailored orders for both doors/windows and aluminum cabinetry.
✅ We provide full customization services with CAD drawings, 3D rendering support, and layout optimization for both window & door systems and built-in aluminum furniture.

6. What Is Your Quality Control Process from Raw Materials to Packaging?
Consistent quality is vital in B2B projects. Ask about raw material sources (e.g., aluminum grade), component selection (glass, hardware), and quality checks.
✅ Our factory uses high-grade 6063-T5 aluminum profiles, multi-point hardware, and tempered insulating glass. Every product passes strict QC including sealing, frame alignment, and surface treatment inspection.

7. What Is Your Monthly Production Capacity and Delivery Time?
For project bidding or bulk orders, make sure the supplier can meet delivery timelines without compromising quality.
✅ With 4 production lines and advanced automation, we support monthly output for up to 10,000㎡ of windows, 5000㎡ of doors, and over 3000㎡ of custom aluminum cabinets. Lead times range from 25–35 days.

8. Do You Offer Installation Support or Technical Consultation?
Even if installation happens on-site abroad, a good manufacturer should offer technical documents and remote guidance.
✅ We provide detailed installation manuals, section drawings, and real-time video assistance for both windows and cabinet modules. Overseas site support can be arranged for large projects.

9. How Do You Handle Shipping and After-Sales Service?
Ensure safe delivery and post-sale support, especially for overseas clients.
✅ We offer professional export packaging with wooden crates, corner protectors, and foam wrap. Our team supports FOB, CIF, and DDP shipping terms. Products come with a 5–10 year structural warranty.

10. How Can I Start a Trial Cooperation or Get a Quotation?
A good supplier should provide a clear starting process—catalogs, sample orders, or online meetings.
✅ You can begin by browsing our official website www.rolaywindows.com and requesting our latest catalog. We also support small batch trial orders and quick-response quotation service within 24 hours.

Partnering with a professional aluminum window, door, and cabinet factory in China can streamline your supply chain and add value to your projects.
