How Chinese window and door manufacturers produce the products

Well. Before getting into the thing. We may as well do some homework, so that we know the business better. To learn what the manufactures do to make the products is a good point to start with. Find the details below.

How Chinese window and door manufacturers produce aluminium windows and doors

The typical manufacturing process of aluminium casement windows and aluminium swing doors follow the steps below:

Profile ordering

Instead of producing themselves. Almost every manufacturer of aluminium windows and doors in China order the profiles. Because extruding the aluminium profiles cost as much as the whole process of the aluminium windows and doors production. The prices of aluminium windows and doors can double or even more. Considering the maintenance cost of the extruding factory and plant.

While ordering the aluminium profiles can pretty much reduce that cost. Thus, the lower operating cost of manufacturing. As a result, more friendly prices of aluminium windows and doors for consumers.

You will find many manufacturers of aluminium windows and doors choose places for their factories. The places near the aluminium extruding factories. For the purpose to save cost on material transportation.

Profile processing

The process includes blanking, punching, pressing, drilling, and milling. Manufacturers usually introduce several sets of machines to complete these actions. So, the key factor to the success of the process is the quality of the machines. Also, the skill of the workers remains critical in this part. They operate the machines after all.

Moreover, the thermal break is critical in profile processing. Aluminium profiles with thermal breaks have much better energy performance. In other words, profiles with thermal breaks make you feel warmer in winters.

EEHE adopt the advanced thermal break technology for profiles of the aluminium windows and doors. Ease your worries of low thermal performance of traditional aluminium windows and doors.

Mounting accessories

Aluminium windows and doors consist of a bunch of accessories. Such as rubber strips, angle brackets, corner joints, hinges, handles, rollers, and etc. An accessory is small, but the bunch of accessories comprise the quality of the windows and doors. Small things matter when it comes to the entire product quality.

EEHE windows and doors select the fine accessories for the aluminium windows and doors. For the enhanced guarantee for your windows and doors by every detail.

Installing the glass

While installing the glass might sound simple. Not every manufacturer of aluminium windows and doors can equip their products with double/triple glass.

By installing double glazed windows, people can save up to 115-120 Euros every year in England, Scotland, and Wales according to a study. And the amount can reach 145 Euros in Northern Ireland.

You can save much more from your utility bills with the triple glazed glass.

If you don’t care much of the utility bills. We believe you still prefer to stay in a place with less noise. And you want to stay warmer in the cold days rather than facing the cold. Double/triple glazed glass will do that for you. They reduce the noise and keep you warmer in winters.

Both double glazed and triple glazed glass are available in the aluminium windows and doors by EEHE.

Finishing the product assembly

When the glass installation is complete. Manufactures will finish the manufacturing process by completing the assembly of the final product.

How Chinese window and door manufacturers produce wood/timber windows and doors

Wood selection

The process of wood selection is critical. Because the wood material largely determines the performance of the final products. For the long run especially. Fine wood material combined with excellent technology can protect the wooden/timber windows and doors from various issues. Like, warping, twisting, shrinking and swelling in most cases.

That’s why wood selection remains crucial in the first place. The common find wood materials include mahogany, Sapele/Sapelli, larch, walnut, white oak, black cherry, and etc.

Wood drying before use

You might find manufacturers keep the wood for some time in the warehouse. Before using the wood for the production of windows and doors. The drying process is to reduce the moisture content of the wood material. Doing so give it a double guarantee to reduce the potential issues like above said of the final products.

Also read Wood Drying on Wikipedia to know more about that.

Machining process including cutting, carving, pressing, milling and etc.

Once the wood is dry enough, the machining process begins. These machining processes prepare the wood slab for the assembly of the wooden/timber windows and doors. Also, the beautiful patterns come into reality from the design by these processes.

Assembling wood slabs and pieces

It’s easy to understand the assembly process of the wood slabs. When you have the experience of playing with the Lego stacks or seeing the others doing so. The final wooden windows and doors products are actually the results of assembling the wood slabs and pieces. After the assembling process, the wooden windows and doors pretty much take their shapes.


After assembling, it’s necessary to polish them. Otherwise, you’ll feel the windows and doors scratchy to touch. Sometimes the tough skin of the wood can make you painful. It hurts indeed. So, enough polish is very important to the wooden/timber windows and doors. The process of polishing and painting intersect often. We’re going to explain in detail later.


Usually, the 1st painting follows the first polish. And there’s a special name for the 1st painting. That is undercoat. The main purpose of the undercoat is to give the first protection from moisture. As you know, moisture is the killer of wood. After the undercoat fully penetrates the wood, the 2nd polish begins.

Then the 2nd painting after the 2nd polish. The name of the 2nd painting is the primer. In old times, the sealer painting comes prior to primer. But nowadays, most primer can serve as a sealer as well. The purpose of it is a double guarantee of moisture protection. Also, to make it easier for the final painting (aka finish) to get with the wood. Without the undercoat and primer, the wood will pretty much absorb the finish.

So, the process of polishing and painting is like this. 1st polish -> 1st painting (undercoat) -> 2nd polish -> 2nd painting (primer) -> 3rd polish -> final painting (finish)

Installing the glass and finished product assembly

When the above processes all complete. Manufactures will install the glass and close up the wooden frames and profiles to complete the production.

How Chinese window and door manufacturers produce uPVC windows and doors

Compared with the manufacturing process of windows and doors made of aluminium or wood/timber materials. The production of uPVC windows and doors requires less process. Generally, the factories follow the below steps to manufacture uPVC windows and doors.

Forming the resin compound

Forming the resin compound is the first step to manufacture the uPVC windows and doors. In the forming stage, manufacturers mix the raw materials to prepare the resin compound.

When the mixture is ready to go, the 2 chemicals (TiO2 and CaCO3) will join the party. And the purpose is to make the material more durable and resistant to UV rays.

Without this process, the uPVC windows and doors will be weak and fragile in the sun. Guess you can easily picture it. If you had the experience of exposing your PVC gloves in hot summers.

Extruding and cooling

After completing the forming stage, then the showtime of the extrusion process. A successful extrusion is key to the structure of uPVC windows and doors. Because it makes the shape of them.

And the success of an extrusion largely depends on the temperature. An environment of 200-275 degree Celsius is desirable. Then the manufacturers will invite the great helper. Large-scale automatic mixing equipment to churn the mix accurately.

After that, the factories will cast the molten mix into a die. Then the die will give the shapes to the extruded uPVC material. It happens during the process of pulling and stretching the material.

Almost immediately, manufacturers cool down the uPVC and give it a water bath. This is mainly to make the uPVC material strong and solid.

Cutting and joining

Then they cut the material into the standard shapes according to the specifications by the clients. And join the individual pieces together by heat fusion welding.

Reinforcement by galvanized steel

To reinforce the structure of the profiles for uPVC windows and doors. Manufacturers will install the galvanized steel sections inside the profiles. Similar to the logic of the steel in the concrete for the buildings.

Installing the glass

After all, manufacturers will fit the glass into the profiles. Until the glass installation is complete. Then it also completes the manufacturing process of uPVC windows and doors.

Thank you for your patience and keep reading till here. We believe you understand more about the windows and doors industry. And get to know how the windows and doors become products from the manufacturing stage. Every detail during the manufacturing process can affect the quality of the final products. We highly recommend you to check the manufacturing process during the factory visits.

Bring this guide with you when doing your purchase of windows and doors in China. Ask the staff and do the comparison accordingly during and after the factory visits. You will be able to distinguish the good windows and doors by yourself.

Other than product quality. The result largely from the manufacturing process and technology. The packing/packaging quality of windows and doors contribute to the quality of your purchase experience as a whole.

How to import directly from Chinese window and door manufacturers

Step 1 of import directly from Chinese window and door manufacturers

The first part is the most important one—choosing a reliable supplier of manufacturer in China. We strongly suggest you choose only from registered manufacturers with verified certifications. And it’s best to see the copy of these certifications. Besides, customer reviews on the internet is another tool you can use to evaluate one supplier. When you make the decision that which manufacturer you want to do business with. You can write them on the list. We should avoid a mistake that only put our eyes on the designs and competitive prices when we choose a supplier. The point we should pay more attention to is focusing on the quality of products and date of delivery.

Step 2 of import directly from Chinese window and door manufacturers

When we get around this mistake, we can further narrow down our possible suppliers list. And then we can go on to the second step—Asking quotations from suppliers. One quotation needs to include prices, delivery periods warranties, terms of sale and how to pay the money, who will pay for the shipping, insurance and transportation costs, and duties to be paid. Through the second step, we can get a final list, including the most professional and quick-responding suppliers.

Through these two steps, we already find the trustable windows and doors suppliers. What we need to do in the next step is about how to transport the products from China to your countries.

Step 3 of import directly from Chinese window and door manufacturers

This is the third step we will talk about—contacting a sourcing agent. A professional sourcing agent can make a big different in doing business with Chinese manufacturers. They can do a lot of things from product quality inspection to the transportation of doors and windows from China to the place you live in. Especially when you buy a great number of furniture, a quality inspection from a third party is necessary. You can ask your manufacture to send some photos about their product details. Or you can ask for a sample, but you may need to pay for it and wait for the time of delivery. The best option is delegating your sourcing agent to do such thing.

About the transportation

As to the transportation, we should have a clear knowledge about tariffs and countervailing charges.

A tariff is tax levied by governments according to the value including freight and insurance of imported products.

China has established a new tax law on import and export. If under tariff rate quota (TFR) schemes, goods imported within the quota are subject to lower tariff rate, and goods imported with higher quota are subjected to higher tariff rates.

Countervailing charges are applied to goods that can be cheaply imported into your country because the manufacturer was given a subsidy by the government as these inexpensive goods are not competitive with the local business (may vary from different countries)

It would be better if you can make a research to know the law of your country on taxes and charges before paying money. In such doing, you don’t need to pay unexpected money for your product.

About the freight

Second, you need to have your good sorted and figure out the cost when you product landed cost refers to the total cost of the product once it has arrived at the buyer’s door. Every fee, clearance, tariff, duties based on goods, import custom clearance and a long list of all importation transactions are included in the landed cost. It would be more advisable to negotiate with a sourcing agent who understands all these requirements. Third, we can hire a shipping company, or a customs broker. The customs broker will straighten everything out for you, what you need to do is contact their staff to trace your shipment. All above is the first approach to import windows and doors online, we will provide the second way to do so.

Make use of resources by Canton Fair

We can get used of the Canton Fair in Guangzhou China. As a platform for the Chinese businessman to show their products, Canton Fair will be held in a yearly basis in Guangzhou China. This massive trade fair offers a chance for the exhibitors to show their products from electronics and household electrical appliances, building materials and hardware, machinery, equipment, fabrics and textile, and many more. Without these three days, you can talk to the exhibitors freely. Admission to Canton Fair is free, but you may need to apply for a visa for entering China. In addition, Language barrier is the problem we should consider, it would be better if we can hire an interpreter.

As we can see, if we choose the second approach, we can discuss with the suppliers face to face and touch the samples manufacturers provide, enabling customers to have a better feeling of products’ quality. The disadvantage is that buyers must make a trip to China and find a way to overcome the language barrier. More money will be costed in this process. When the doors and windows you buy travel all the way to your house, it’s time to ask the local builders for help, you need their help to install the beautiful windows and doors to your house. Before making a phone call to the builders, you should remember to ask the installing specifications of your door and windows from suppliers. Or you can choose to do it yourself If you’re patient enough and have a lot of time. You can install them by yourself. But installing furniture is a complex process, which need you to know a lot about furniture instruction. And there are lots of procedures which are difficult for one person to finish.

Common issues in import and export business

Delivery time

The delay of delivery is common to see especially in international business. For the transportation in long distance. Your goods experience a series of transit from the Chinese window and door manufacturer to your hands. Even if you pay great attention to the details. Still, there are chances for unexpected events. Delays can result from many reasons. Such as holidays, bad weather, political events like G20 or so.

However, you hardly see these issues with strong manufacturers. Although might be issues from time to time still. A strong supplier will handle that much better and lower your loss. For their professional service and cooperative teamwork as a result of their rich experience. Thus, it’s important choose a reliable manufacturer like EEHE for timely delivery of your windows and doors.

Incomplete Documentation

Incomplete documents will slow the shipment of your ordered doors and windows. The cost of delivering Bill of Lading, Packing List, Commercial List, and other documents through courier are often paid by the importer. But if you place a high volume of order, suppliers will be willing to pay this charge for you.

Damaged Packaging

doors and windows are fragile and may easily be damaged while being transported because of their raw material. Products may not be protected well if the supplier do not pay more attention to the packing process. It would be better if we can emphasize the protection of products in your contract, or the manufacturer will pay for any damage.

Colour Difference

if there is a different between the colour of the sample and that of the products we receive. We should contact the supplier for returns and refunds. Or we can write terms about colour difference in the contract to avoid troubles.

  • AS2047 Windows in buildings – Selection and installation

  • AS1288 Glass in buildings – Selection and installation

Windows made from timber, aluminium, uPVC or other materials undergo the following performance tests to verify product performance claims.

  • AS4420.2 Deflection Test – positive and negative wind pressures are applied to the face of the window to test the maximum deflection under wind load.

  • AS4420.3 Operating Force Test – verifies that an opening sash is capable of opening and closing without undue effort.

  • AS4220.4 Air Infiltration Test – air leakage of a window is tested to ensure energy and acoustic efficiency.

  • AS4420.5 Water Penetration Resistance Test – ensures no water leaks through the window into the building.

  • AS4420.6 Ultimate Strength Test – negative and positive wind pressures of at least 1.5 times the specified wind pressure are applied to the window to ensure it does not fail in unusual wind conditions.


That’s a lot, right? We do know that. But try to ask the manufacturers in China. They will probably figure it out for you. Once you get the hang of it, you’re going to move a great step. For your money-saving journey with the Chinese window and door manufacturers.
