    Hand-forged ornamental iron was the first type of steel fencing dating back to the early 1800’s. Individual parts were hand-forged in iron shops, where the steel was heated at high temperatures and formed into shape by a black smith. Forged metal is extremely durable but due to the process involved of forging each part takes a considerable amount of time to make which drives the cost up. Today, this type of fencing is extremely rare with very few craftsmen making this type of ornamental fencing.

    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.
