Differences between Bendable Aluminum Strips and Ordinary Aluminum Strips

Ordinary Hollow Aluminum Spacer Bar

  1. The ordinary hollow aluminum spacer bar is produced using the cold drawing and solidification method by Yintong, undergoing five stretches through a cold rolling stretching device, then transforming into a square shape, and finally becoming finished products after processes like punching. Some chemical materials are used in the five-stage cold drawing production process. Therefore, the discharge of chemical wastewater during production will cause pollution to the environment and generally does not meet the national production standards.
  2. The surface of the ordinary hollow aluminum spacer bar is relatively dull, lacks glossiness, and has poor flatness. If the surface treatment is not done well, there may be phenomena such as chipping and uneven air holes.
  3. The ordinary hollow aluminum spacer bar is not resistant to oxidation and corrosion, and it has a certain impact on the activity of desiccants, thus shortening the service life of insulating glass.

  1. Production Technology: The bendable and non-bendable high-frequency welded hollow aluminum spacer bars are produced using German technology with a waterless circulation system, and they are welded after the aluminum strip is shaped by pressure. The production process is environmentally friendly and is recommended by the national production equipment.
  2. Material: High-quality corrosion-resistant high-purity aluminum is selected, with a wall thickness of 0.35mm, ensuring quality.
  3. Advantages:
    • It does not oxidize or corrode; even in areas with frequent rainfall or high humidity, it is not easily hydrolyzed or corroded, thereby extending the service life of insulating glass.
    • The surface has high brightness and glossiness, is smooth and even, and is free from chipping.
    • Welding defects are eliminated, with double-row perforations, uniform hole penetration, and good straightness.
    • It has no effect on desiccants, ensuring the activity of molecular sieves, and has excellent adhesion with various adhesives.
    • It has high strength, good toughness, no deformation, and stable dimensions.

Bendable High-Frequency Welded Hollow Aluminum Spacer Bar

Compared to the non-bendable high-frequency welded hollow aluminum spacer bar, the quality of the bendable high-frequency welded aluminum bar is absolutely better. However, it also has a significant advantage for insulating glass:

The usual installation method of aluminum spacer bars involves using four connecting angles to make insulating glass. If the operation is not good, the sealing effect of the four corners of the insulating glass will be poor. The first performance of insulating glass is usually an increase in leakage points, which can lead to air leakage and penetration. This is highly likely to cause insulating glass failure, shortening its service life. However, the bendable high-frequency welded aluminum spacer bar eliminates the root cause of leakage at the four corners through continuous bending during installation and use. The standard forming of the aluminum frame does not deform, making it more convenient for glass and films. The produced insulating glass has high reliability and will not affect the quality of insulating glass products due to leakage at the four corners.

The best solution for aluminum window bending. The PBA series aluminum bending machine solves the springback problem with one click and achieves perfect bending.

Differences between Bendable Aluminum Strips and Ordinary Aluminum Strips

  1. Compared to ordinary aluminum strips, bendable aluminum strips (also known as bendable aluminum strips or bending aluminum strips) have the following advantages:
  1. Rust resistance, corrosion resistance, and high brightness.
  2. The surface porosity of the aluminum strips is uniform, with good straightness, no deformation, and stable dimensions.
  3. High strength, good toughness, and can be continuously bent into any angle of aluminum frames with bending equipment.
  4. Ensure the activity of the molecular sieve and excellent adhesion with various adhesives.

Advantages of using bendable aluminum strips (also known as bending aluminum strips) in insulating glass

  1. Ordinary aluminum strips use four connecting angles to make insulating glass, and the sealing effect of the four corners of the insulating glass made by ordinary aluminum strips is poor, making it most prone to air leakage and water infiltration, which easily leads to insulating glass failure and shortens its service life.
  2. Bendable aluminum strips made with high-frequency welding adopt a right-angle connection to make insulating glass. There are no connecting components at the four corners of the insulating glass made with bendable aluminum strips, resulting in an excellent sealing effect. It is not easy to leak air or water, thus prolonging the service life of the insulating glass. At the same time, its performance and appearance can compete with similar foreign products.

Differences between Integrated Bending Aluminum Strips and Jointed Aluminum Strips

Integrated bending aluminum strips have higher strength and stability in the bending process, and they are less prone to deformation. Additionally, even in humid cities in the southern regions, they are less susceptible to corrosion and rust. On the other hand, ordinary jointed aluminum strips use four connecting angles to make insulating glass. The sealing effect at the four corners of the insulating glass made with ordinary jointed aluminum strips is poor, making it more prone to air leakage and water infiltration. This greatly increases the risk of insulating glass failure and shortens its service life.
