To clean the surface of seamless square tubes, no dirt should be present. For prefabricated components located in critical areas, equipment can be used for sanding and polishing until the surface is as bright as new. After preparation, the installation can begin. The installation of prefabricated components for seamless square tubes generally requires hoisting. During hoisting, two wind ropes can be tied to the sides of the component to control its position. Whether it's the hoisting process or adjusting the position, the entire process must be done slowly, as there are fewer points of force in the air. Faster speeds may cause the component to become unstable and result in bumps and collisions.

By adopting a "simplify to complicate" approach during equipment assembly, disorganized parts can be optimized into manageable units before full-scale assembly. This method significantly enhances equipment speed, reduces complexity, and improves accuracy.

Seamless square tubes are perhaps most prevalent in the manufacturing industry, particularly in the engineering and construction sector. However, when discussing seamless square tubes in conjunction with decorative building materials, it's inevitable to mention prestressed rebars. This is primarily due to the high requirements for the compressive strength of fine wires in the construction industry. The composition of prestressed rebars is not well-known to many; it is mainly made up of individual or bundled stainless steel wires, steel strand, or reinforcing bars.

Bonded prestressed reinforcement bars are those that are immediately bonded with concrete or bonded with concrete after tensioning based on grouting. Unbonded prestressed reinforcement bars, on the other hand, are made by coating stainless steel plates with plastics or other materials, and can be placed within or outside the reinforced concrete structure. It is important to note that they cannot be bonded with concrete.
