Mainly divided into ordinary channel steel (U-beam steel) and light channel steel (light U-beam steel).
Can also be identified as such: channel steel is formed by hot rolling process, U-beam is generally cold state roll molding.
The biggest difference between the two is the thickness: the overall thickness of the channel steel is not the same as the overall thickness of the light U-beam steel is the same
Detailed description is as follows:
Cold-formed U-beam steel refers to the cold state, the professional equipment roll-forming one time molding, is a kind of economic cross-section of lightweight thin-walled steel, known as steel refrigeration bending efficient energy-saving profiles. According to the shape can be divided into four types: cold-formed equal-edge channel, cold-formed unequal channel, cold-formed inner rolled-edge channel, cold-formed outer rolled-edge channel
It has a variety of hot-rolled can not be produced by a variety of extra-thin, reasonably shaped and complex cross-section. Compared with hot-rolled steel, in the case of the same cross-sectional area,
The radius of gyration can be increased by 45 to 60%, the moment of inertia of the cross-section can be increased by 0.4 to 3.0 times, and thus can be a more reasonable use of the strength of the material;
Ordinary steel structure (i.e., by the traditional steel I-beam, channel, angle and steel plate production of the steel structure) compared to the steel savings of about 25 to 50%. In some cases, the amount of steel used in cold-formed U-beam structures is comparable to that used in reinforced concrete structures under the same conditions, making it a kind of economic section steel.
The main characteristics of U-beam steel support: bear pressure, support for a long time, easy to install and not easy to deform
Widely used in various fields, its use can be roughly divided into highway guardrail plate, steel structure, steel template and scaffolding, ships and bridges, railroad vehicles, steel sheet piling, automobiles, containers, transmission towers and so on.
The thickness of the product can be from 0.9-12mm. the specification is 20-400mm.
