How Doorwin Contributes to Your Own Business Space?

Thousands of completed projects across both residential and commercial sectors and thousands of satisfied customers spread all over the world show that Doorwin is competent for large-scale projects. Take a look at one of our completed projects in Austin, Texas of the U.S below.

About The Project

This project is located in Austin, Texas, the Phase I of this project totally has 42 units buildings for apartments and one for clubhouse. This complex of apartments has total area of 2550.59 square meters, based on the client’s requirements and Doorwin’s solution, we used Architect series Alu+ 70 thermal break aluminum windows with custom designed features, such as interior white frame and exterior black frame.

All the materials used are selected to ensure providing the client with high-grade products:

Such as high energy-saving TGI warm edge spacer (world's top brand - Technoform Bautec warm edge strip) which will greatly improve the overall thermal insulation performance of your windows.

In addition, Germany-origin brand ROTO/SIEGENIA hardware system for high strength and aesthetic. The hinges are hidden, making the window more aesthetic and a cleaner exterior appeal.

Tempered safety glass complies with international standards to face all kinds of extreme weather or safety issues. Furthermore, doors and windows of this type frequently rely on multiple panes glazing for structural stability. In other words, common products in the market with thinner aluminum may not provide the strength required owning to their smaller proportion of frames.

We use fully tempered double glazing to provide good performance in security and durable issues in front of extreme weather, and also provide a degree of thermal insulation at the same time.

Durable extruded aluminum nail fin makes the installation much easier and more convenient. In the U.S., labor costs during installation can exceed 30% of the typical window and door price, therefore, our exclusive nail fin allows users to not only get a significant increase in installation efficiency but also greatly reduce the cost of window and door installation.

Sleek, innovative modern apartment featuring Doorwin’s top-quality aluminum windows that create a nice look and feel while providing superior functionality.

Sliding Door for Large Opening in the Project

In this project, we applied thermal break aluminum lift and slide door with double panes Low-E glazing to meet the requirements of the clubhouse's large opening entrance and the energy efficiency capacity. Doorwin's lift and slide doors, featuring the world's top hardware brands - Maco, Siegenia, offer the ultimate solution for large and heavy sliding sash doors. The possibilities in this system allow energy efficiency, magnificent size, effortless operation, and security.

You can upgrade it to an automated system (remote controller available). The automated system can quickly accelerate the front 36" lead panel, allowing quick entry and exit. It knows where each individual panel collection point is. The motor slows down to pick up each panel, picks up the panel, then accelerates to the next panel, repeating the process until the system is in the fully on or fully off position.

What Makes Doorwin Products One Of The Best Choices For Buildings?

Our expertise is reflected in:


We have several international patents to reduce clients’ labor costs, such as our unique flanges and assembly type tubular design, which is different from the other products on the market. What sets us apart from our Chinese counterparts is that all our products are equipped with nail fin structures for quick and easy installation. Labor costs during installation may exceed the window and door price, therefore, our exclusive patent allows users to not only get a significant increase in installation efficiency but also greatly reduce the labor cost of window and door installation. A cost that may bring you unexpected savings that far exceed the price difference you may care about now.


During the epidemic, it is very difficult to book shipping containers for export (not simply the increasing fees, many exporters cannot book containers on time) which will not only directly affect the normal schedule of your project, but also will cause you a greater increase in costs that were not expected. We are the only "Alibaba Elite" merchant in the window and door industry on this platform, we have priority booking rights and get the best price for the shipping, so we can guarantee that your goods will arrive as scheduled and will save you a lot of money.

independent tests guarantee Doorwin’s products can meet all customers’ expectations and satisfaction.


We export tens of millions of dollars of windows and doors to the U.S. every year, and we know that improper packaging can cause breakage of the product when it arrives on site, and the biggest loss from this is, I'm afraid, the cost of time, after all, workers on site have requirements of working time and it needs to wait for a new shipment to arrive in case of damage occurs to the goods. So, we pack each window individually and in four layers, and finally into wooden boxes with non-fumigation, and at the same time, there will be a lot of shockproof measures in the container, to protect your products. We are very experienced in how to pack and protect our products to ensure they arrive at the sites in good condition after long-distance transportation. What the client concerns, we concern most.
