          Square tubes have various applications on door and window frames, including:
          1. Material and Structure
                  Durable and sturdy: Square tubes are usually made of aluminum alloy or steel. Aluminum alloy square tube has the characteristics of light weight and corrosion resistance, which can effectively reduce the overall weight of doors and windows, while ensuring long-term use without rusting or deformation; Steel square tubes have higher strength and can withstand greater external forces, making them suitable for places with high requirements for door and window durability. The hollow structure of the square tube ensures strength while also saving materials and reducing costs.
          2. Appearance design
                 Simple and beautiful: The square tube has a simple and smooth appearance with straight lines, which can bring a modern and simple appearance style to doors and windows. It can be well integrated with various architectural styles, whether it is a modern and simple style residential building or a traditional style building such as European and Chinese. Through the reasonable design and matching of the square tube, unique door and window shapes can be displayed.
                 Strong customizability: Square tubes can be processed into various shapes and sizes of door and window frames through cutting, welding, and other methods to meet different design needs. For example, different specifications of square tube frames can be customized according to the size and opening method of the windows, and the square tubes can be bent into arcs to create unique arched doors and windows, increasing the aesthetics and uniqueness of the building.
          3. Functional characteristics
                Good sealing performance: The door and window frames made of square tube splicing, combined with excellent sealing strips and hardware accessories, can effectively improve the sealing performance of doors and windows. When closing doors and windows, the square tube frame can tightly adhere to the door and window sashes, preventing air, rainwater, and other infiltration, providing good sound insulation, heat insulation, and waterproofing effects, and improving indoor comfort.
                Easy to install: The standardized size and regular shape of the square tube make it more convenient and efficient during installation. Construction personnel can perform simple cutting and assembly of pipes according to the actual situation on site, reducing installation time and costs. At the same time, the connection between the square tube frame and the wall is also relatively convenient, which can be firmly fixed by expansion bolts and other connecting parts to ensure the stability and safety of doors and windows.
