GI slotted C-channel refers to a new type of steel made from high-strength steel plates, formed by cold bending and roll forming, characterized by uniform wall thickness, sectional functionality, and high strength. Due to these characteristics, GI slotted C-channel is widely used in the purlins and wall beams of steel structure buildings. It can also be combined independently into lightweight trusses, brackets, and other building components, and used in columns, beams, and arms in light mechanical manufacturing. In some seismic support and hangars, GI slotted C-channel is also used as the primary material.
Firstly, in terms of providing stable support, GI slotted C-channel, as the core load-bearing component of seismic supports, is designed with full consideration of the massive impact force that natural disasters like earthquakes exert on building structures. The precise cold bending and roll forming processes ensure uniformity and high strength of the section, allowing it to provide continuous and stable support for building structures during an earthquake. This stable support helps maintain the integrity of the building structure and effectively prevents collapse and damage caused by earthquakes.
Secondly, GI slotted C-channel excels in dispersing and absorbing energy. Its unique sectional shape and excellent mechanical properties enable it to effectively distribute the energy generated by an earthquake throughout the entire structure, thereby reducing the impact on a single area. Additionally, through reasonable layout and design, GI slotted C-channel can absorb a significant amount of energy during an earthquake, further reducing the damage sustained by the building structure.
Finally, the standardized production of GI slotted C-channel brings great convenience to installation and maintenance. Due to the standardized production process, the dimensions and shapes of this steel type are kept highly consistent, significantly simplifying the installation process. Furthermore, the galvanized layer not only enhances the corrosion resistance of the steel but also reduces maintenance costs caused by corrosion. This means that in the seismic supports constructed with GI slotted C-channel, maintenance costs will be effectively controlled, extending the overall lifespan of the supports.
So how is GI slotted C-channel produced? As it is widely used in building components, the production process is also very stringent. Traditionally, production required several people on a single production line, which was time-consuming and labor-intensive. Nowadays, many factories can achieve automated production lines. C-shaped steel is made by cold bending hot-rolled sheets, resulting in a thin wall and light weight, with high sectional functionality and strength. Compared to traditional channel steel, it can save 30% of material for the same strength.
GI slotted C-channel has the advantages of adjustable standard dimensions and high compressive strength. Despite the lightweight appearance of cold-formed steel, its sectional dimensions align perfectly with the stress characteristics of roof purlins, allowing full utilization of the steel's mechanical properties.
