- Hinges, another crucial component, bear the weight of doors and windows, allowing them to open and close smoothly. They are available in different materials, sizes, and styles to accommodate various design requirements and load-bearing capacities. From traditional brass to modern stainless steel, hinges not only serve a functional purpose but also contribute to the aesthetic appeal.
- One of the most distinctive features of a metal money box with a key is its hinged lid, which secures with a sturdy lock mechanism. The inclusion of a key adds an extra layer of security, ensuring that the contents remain protected from unwanted intruders. To access the savings inside, one simply inserts the key into the lock, turning it until the lid lifts open.
- 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.
Aluminium extrusion profiles also play a vital role in the manufacturing of sliding windows and casement windows. The versatility of extruded profiles enables the creation of smooth gliding mechanisms for sliding windows, ensuring effortless operation. Casement windows benefit from the strength and rigidity of aluminium, providing excellent security and weather resistance.
Cast Iron Railing Panel
Another benefit of aluminum window extrusion profiles is their sleek and modern look. The slim frames of aluminum windows allow for larger panes of glass, maximizing natural light and views from inside the home. Additionally, aluminum frames can be designed with clean lines and sharp angles, creating a contemporary and minimalist aesthetic that is popular in modern architecture.

WHAT ARE THE TYPES OF ALUMINIUM WINDOWS?
Cultural Significance
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.
Aluminium Windows Profiles
Aluminum window frames are specially designed profiles cut at 45° to assembly the window’s angles. These profiles are often composed of two profiles: a base element and a snap closure element to secure the glass. Beside windows, this kind of aluminum frame profiles are most used for the creation of wall boards, like those placed in public offices.
Both cast and wrought iron are some of the most durable materials out there. With proper care, iron fences can last for generations.
Fence brackets are unique to wrought iron fences and often used to hold the fencing components to the posts. These slide over the rails, are set against the posts and are often then secured with a self-tapping screw to hold everything together. Aluminium fencing does not use brackets. Instead, rails are slid into punches in an aluminium post and then a self-tapping screw is driven through the post and into a rail inside it in order to secure everything.
Aluminum vs Wrought Iron Fence: What are the Differences and Which is Better?
Many ornamental cast iron manufacturers also offer customization services, allowing customers to create unique pieces that suit their specific needs and preferences. Whether it's a custom gate for a private residence or a decorative railing for a commercial building, manufacturers can work closely with their clients to bring their vision to life.

ornamental iron castings. Whether you prefer a more traditional look with classic scrollwork and floral patterns, or a more modern and minimalist design, iron castings can be tailored to match your vision. This flexibility makes them a popular choice for designers and architects looking to add a unique and personalized touch to their projects.
