Seam lock round pipe and square pipe are types of hollow steel pipes that are commonly used in construction and industrial applications. These pipes are made by forming a continuous seam along the length of the pipe, which is then securely locked into place to create a strong and durable structure. The round pipe features a cylindrical shape, while the square pipe has a square cross-section. Both types of pipes are available in various sizes and dimensions to suit different project requirements. Seam lock round pipe and square pipe are known for their excellent structural integrity, high strength, and resistance to bending and twisting. They are commonly used in the construction of buildings, bridges, fences, and other structures where strength and durability are essential. Overall, seam lock round pipe and square pipe are reliable and versatile building materials that offer a cost-effective and practical solution for a wide range of construction projects. 锁缝圆管与方管是建筑工程及工业领域中常用的空心钢管类型。这类管材通过沿管体纵向成型连续接缝并经机械锁固工艺制成，具有结构坚固、经久耐用的特性。其中圆管呈标准圆柱造型，方管则为矩形截面结构。两种管材均提供多种规格尺寸，可满足不同工程项目的需求。
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。
Saw cutting unit is used for cutting closed profiles. This unit typically consists of a sharp disc that rotates at high speed to make precise and clean cuts through the material. 锯切机构专用于闭口型材的切割加工，该装置通常配备高速旋转的锋利圆锯片，可实现材料的精密切割并确保切口光洁平整。
