Frequently Asked Questions
What's the price per square meter? / How much does it cost?
Our products are custom-made. The final price depends on specifications, material configuration (e.g., profile thickness, glass type), design complexity, and order quantity. Please share your basic project information (purpose, dimensions, reference images), and we will provide a transparent, detailed itemized quotation so you understand the value behind every cost.
Can I get a sample? Is it free?
Absolutely. We encourage you to verify quality firsthand. We offer a limited number of free small samples (e.g., color swatches, small cuttings), for which you only need to cover the international courier cost. For functional parts or larger samples, a nominal fee may apply, which will be fully credited against your future bulk order.
What is your return and refund policy?
We strive for perfection in every order. For products with confirmed manufacturing defects or non-conformity with agreed specifications, we are responsible for repair, replacement, or compensation as per agreement. Due to the highly customized nature of our products, we strongly advise careful review of all designs before order confirmation for returns based on non-quality issues. We are open to discussing case-by-case solutions.
Can you help with installation?
We provide detailed installation manuals, HD video tutorials, and ongoing remote technical support. For large or complex projects, we can recommend experienced local installers or dispatch our technicians for on-site guidance (this may incur additional costs, negotiable).
I have my own design. Can you customize it?
Absolutely! Customization is our core strength. Please send us your sketches or renderings. Our engineering team will conduct a feasibility study, offer optimization advice, and provide professional detailed drawings for your approval.
What are the shipping costs and delivery time?
Shipping Costs: These depend on the total order volume, weight, destination, and your chosen trade terms (e.g., FOB, CIF). We will propose the most cost-effective logistics solution upon order confirmation. Lead Time: Typically, production for standard orders takes 10-15 days (starting from receipt of deposit and final approved drawings). The exact timeline is subject to our production schedule and project complexity. We maintain transparent communication throughout the process.
