A UA profile for a door frame by roll former is a specially designed metal profile that is created using a roll forming machine. The UA profile is engineered to provide structural support and stability to the door frame, ensuring durability and longevity. Its unique shape features a combination of a U-shaped channel with a flat top flange, creating a strong and rigid structure that can withstand the weight and pressure of the door. The UA profile is typically made from high-quality galvanized steel, which is selected for their strength and corrosion resistance properties. The profile is produced by passing coils of metal through a series of rollers on a roll forming machine, which shapes the metal into the desired UA profile design. This process ensures precise and consistent dimensions for each piece, making installation easy and seamless. 门框用UA型材是一种通过辊压成型机加工的特制金属构件。该型材采用独特的U型槽道与平面顶部法兰相结合的创新结构，能为门框提供卓越的支撑强度和稳定性，确保其经久耐用。
Roll former is used to create uniform, continuous bends in metal materials. It works by passing a strip of material through a series of rollers that gradually bend and form the material into its desired shape. 辊压成型机用于在金属材料上形成均匀、连续的弯曲。其工作原理是将金属带材依次通过多组轧辊，通过渐进式弯曲使材料成型为所需形状。
Hydraulic cutting unit is used to provide smooth and clean cuts. It is typically operated by a control panel that allows the user to adjust the cutting speed and pressure according to the material being cut. 液压剪切机构用于实现平滑精准的切割作业，该设备通常配备智能控制面板，操作人员可根据不同材料的特性，实时调节切割速度与压力参数。
