Your Questions Answered

Common FAQ

1. What is the minimum wholesale order quantity?
There is no strict minimum order — we cater to both small residential needs and large commercial bulk orders. Contact us with your exact requirement for the best tiered pricing.
2. Do you deliver outside Chennai?
Yes! We actively supply across Tamil Nadu, Andhra Pradesh, Karnataka, and Kerala. We also fulfill export orders easily. Transportation charges are extra and determined based on the destination.
3. Can I pick up my order directly from the warehouse?
Yes, customers are welcome to pick up their orders directly from our warehouse in Chennai. Please coordinate with our team at least 2 hours in advance to ensure your order is ready for loading.
4. Can I request samples before placing a bulk order?
Absolutely. We understand the need to verify quality. You can reach out to us via WhatsApp or our contact form, and we'll arrange prompt sample delivery to your site.
5. Which profile series do you currently stock?
Our ready-stock includes the 60 SERIES for Casement systems, the 60 SERIES for Sliding systems, and our flagship 80 SERIES Industrial-grade series.
6. Do you supply custom colored or wood-finish uPVC profiles?
Yes! Beyond the standard White, we supply laminated woodgrain finishes and custom solid RAL colors on request. Please note that custom colors may require a lead time of 7–14 days depending on availability.
7. What makes your profiles suitable for harsh coastal areas?
Our premium profiles feature exceptionally thick walls (up to 2.5mm) and are specially enriched with Titanium Dioxide to provide superior UV stability. This entirely prevents yellowing, fading, and cracking under intense sun and salty ocean air.
8. Do you provide professional grade sealants?
Yes, we stock high-performance neutral-cure and weatherseal silicones, specifically selected for professional window and door masonry finishing to ensure long-term airtight and watertight seals.
9. How quickly can I get a quotation for my project?
We pride ourselves on fast turnaround times. Submit your material requirements (series and quantity) through our Inquiry Form or send a direct message via WhatsApp, and we typically reply with a formal quote within 2 business hours.
10. Do you provide window fabrication and installation services?
As a wholesale supplier, our primary focus is material supply. However, we have a robust, verified network of trusted fabrication and installation partners. If requested, we can gladly recommend highly qualified fabricators in your specific city.
