- Surface treatment: This is very important because door and window profiles are subject to different surface treatments depending on the environment in which they are used. Generally, door and window profiles will be coated with fluorocarbon coating, powder coating, anodized, and electrophoresis. Among them, anodic oxidation is a standard surface treatment method. Through the electrolytic reaction in the electrolyte, an oxide film is formed on the surface of the aluminum alloy to protect the aluminum alloy material.
Surface finish: This dramatically impacts the performance of doors and windows. If the surface finish is not good, the corrosion resistance, wear resistance, oxidation resistance and other properties of doors and windows may be reduced.
Size: There are two types of door and window profile sizes, one is standard size and the other is customized size. We can make custom sizes according to your project needs.
Quality standards: There are different quality standards for door and window profiles. According to your local requirements, you can refer to the standards of profiles and provide requirements to the manufacturer. Or you can take the profile's weight, appearance, hardness, strength, and oxide film.
thickness as a reference direction and coordinate with the aluminum material manufacturer.
Thickness: This is one of the important indicators of doors and windows, which is directly related to the safety performance of doors and windows. The wall thickness of the main stress-bearing rods of aluminum alloy doors and windows should be more than 1.4 mm. The wall thickness of the main stress-bearing rods of aluminum alloy doors should be more than 2.0 mm. The tensile strength should reach 157N/mm.
Type: There are many types of profiles now which can fully meet the needs of any project. Generally, different use environments will have specific profiles to choose from.
For example:
Standard aluminum door and window profiles
Thermally broken aluminum door and window profiles
Sliding aluminum windows and doors profiles
Casement aluminum windows and doors profiles
Folding aluminum windows and doors profiles
Soundproof aluminum alloy profile
Generally, the profile configuration should be selected according to the project requirements when choosing aluminum materials for doors and windows. If you have special requirements, you can communicate with the aluminum profile manufacturer. Now the technology from extrusion to processing door and window profiles is very mature. As a professional aluminum factory, we have produced aluminum for any project. We are fully confident in producing aluminum for any project.
Assembly: If the profiles are to be used in window frames or other assemblies, they will be joined together using mechanical fasteners, adhesives, or other methods.
After being heated to very high temperatures, the molten steel is poured into molds. After being allowed to cool, the components are removed from their molds, cleaned to remove any burns or extra edges, and then prepared for painting.

The drawbacks of iron fences are that they are often difficult to install, and the materials are very expensive.
Next, locate the roller assembly, which is typically situated at the top of the door. There may be one or two rollers, depending on the door design. Use your screwdriver to remove the screws securing the roller assembly to the door. Some doors may have a cover that needs to be taken off before accessing the rollers; gently pry it off with pliers if necessary.

Cast iron's inherent strength makes it a desirable material for various industrial applications. It has a lower melting point and a higher fluidity than other materials. Castability Due to the simplicity with which it may be cast, cast iron finds use in a diverse range of sectors.

gate lock box weldable steel. This eliminates the need for additional hardware or tools, making the installation process quick and hassle-free. Once installed, the lock box will blend seamlessly with the gate, maintaining its sleek and unobtrusive appearance.
The best construction method for iron fence is one that is strong and looks good from both sides. Below are a couple of photos showing how we build our Stronghold Iron fence with a punched rail and fully welded construction at the picket-to-rail intersection and for the decorative finial tip. You can see the picket (upright) goes through the middle of the punched rail for a strong connection and clean look from both sides of the fence:
The charm of decorative wrought iron pieces lies in their rich history, exquisite craftsmanship, and timeless appeal. They serve as a testament to the skill and artistry of the blacksmith, transforming functional items into beautiful works of art. As trends come and go, wrought iron remains a staple in design, celebrated for its durability and aesthetic versatility. Whether enhancing a garden, adding elegance to an entryway, or creating a unique focal point in interior decor, decorative wrought iron pieces continue to capture the attention and admiration of many. Embracing wrought iron in design not only pays homage to centuries of craftsmanship but also enriches our surroundings with beauty and character.

Nonetheless, typical aluminum profiles for windows and doors can last for more than 10 years.
Aluminum ornamental iron fencing is becoming the most popular type of fencing especially for residential fencing. Cost is definitely the driving force because aluminum fencing can be manufactured in large quantities at a faster production rate and at a lower cost of production. Aluminum fencing is produced through an extrusion process that basically pushes aluminum blocks of materials through a die system that adheres to the contour of that particular die. Once the piece is formed, the components of the different style of ornamental fencing goes through several steps of priming and powder coating, boxed and ready for shipment from the manufactures to different distributors located throughout the U.S.
Aluminum is the best aluminum profiles door & window and deep processing supplier.
1. We use high quality thermally broken raw materials as insulation bars. By adding an insulation bar to aluminum profiles, we form an insulation barrier to prevent heat transfer from outside and inside. The material of the insulation bar is PA66 nylon, which has good toughness and strength. Therefore, it has a good insulation effect.
2. A wide variety of finish options are available for your different coating requirements. Powder coating, anodizing and wood grain finishes are the most popular choices for extruded aluminum door & window frames.
Established over 11 years ago, our company has been one of China's best aluminum profile suppliers. And since 2011, when we started exporting our products, we have become one of the best suppliers in the world.
Customer service is yet another vital aspect to consider. A reliable wrought iron supplier should be responsive and willing to assist clients throughout the purchasing process. This includes providing timely quotes, answering questions, and offering support during delivery and installation. Strong communication can help to build trust and ensure that any issues that may arise can be addressed swiftly and effectively.


Overall, aluminum window extrusion profiles are a durable, versatile, and stylish option for windows in residential and commercial buildings. While they may have some drawbacks in terms of thermal performance, these can be mitigated with the right design and insulation choices. With proper care and maintenance, aluminum windows can provide homeowners with long-lasting beauty and functionality for years to come.
Cast iron spears became especially prominent in regions where iron smelting technologies were developed. The ability to mass-produce weaponry meant that armies could equip a larger number of soldiers, contributing to the rise and fall of empires. For instance, in Ancient China and Europe, armies equipped with cast iron spears had a tactical advantage due to their durability and adaptability in various combat scenarios.
Common models of fixed window profiles include: 6063-T5, 6061-T6, etc.
