Inside ETBOX: How We Ensure Quality from Factory to Site
Let’s be honest: in our line of work, “quality control” is a term that gets thrown around a lot. But for us at ETBOX, as a professional B2B Windows & Doors Supplier, it’s not just a department or a checklist. It’s the way we do business. When you partner with us for your Windows & Doors construction solutions, you’re not just buying building materials; you’re buying peace of mind. You need to know that the products will perform, on time and as promised, every single time.
So, how do we make sure that happens? Here’s our no-nonsense approach to quality control from factory to site.
- It All Starts with Superior Building Materials
You can’t build great construction solutions with subpar materials. That’s why our first and most crucial step is picking the best suppliers for our windows & doors components. We’re picky. We work with partners who share our obsession with quality control, rigorously testing everything from the strength and finish of our aluminium to the clarity and performance of our glass.
- We Prototype Life Out of It
Before we ever fire up the full production line, our engineering team gets hands-on. They build prototypes and put them through their paces, ensuring our windows & doors meet both performance standards and practical installation requirements. For customWindows & Doors construction solutions, we’ll often send a sample unit your way for hands-on review.
- Production: Where Precision Meets Quality Control

Once you’ve signed off, our factory kicks into gear with digital tracking at every station. Every windows & doors product must pass rigorous checkpoints for measurements, finish quality, and hardware operation. This systematic approach to quality control guarantees the product you receive matches your specifications exactly.
- The Final Performance Exam
Before anything gets wrapped up, it faces brutal testing for weather tightness and thermal performance. We ensure our building materials don’t just look good in the showroom; they perform year after year in real-world conditions.
- Packaging Built for Global Logistics

We’ve engineered our packaging to survive international shipping. Each product is securely crated in custom timber boxes with QR code tracking, ensuring your building materials arrive on site in perfect condition.
- Reliable Logistics from Factory to Site
Our logistics team handles everything from customs to final delivery. We coordinate with your project schedule and provide real-time updates, ensuring materials arrive on time, every time.
