Construction and Decoration Materials

Cold Formed for Television Towers (Channels- Angles- C Channels- steel sheet piles)

    Application: Construction

    Type: Carbon Structural Steel

Cold-formed steel is the common term for products made by rolling or pressing steel 

into semi-finished or finished goods at relatively low temperatures (cold working). 

Cold-formed steel goods are created by the working of steel billet, bar, or sheet 

using stamping, rolling (including roll forming), or presses to deform it into a usable product. 

Cold-worked steel products, such as cold-rolled steel bar stock and sheet, are commonly 

used in all areas of manufacturing of durable goods, such as appliances or automobiles, 

but the phrase cold-formed steel is most prevalently used to describe construction materials.

Shanghai Metal Corporation's Cold-formed Steel Sections are suitable for practically any kind of steel 

structure, whether for commercial or residential use. They are also available for use in machines and appliances.

Tolerances of Cold formed Channel Steel: 

Dimensional and cross-sectional tolerances of cold-formed sections are specified in EN 10162. Customer-specific tolerances can be agreed on separately. SMC also offers tolerances with cross-sectional wall thicknesses of >8- ≤12.5 mm. The standard states that the tolerances in this thickness range are to be agreed on separately.

Advantages of Cold formed Channel Steel:
1) The strength to weight ratio is excellent
2) Metals join easily
3) Efficient shapes are available, etc.
These advantages create challenges that are best solved by a good understanding of how the metals actually perform in a structure.

The use of cold-formed steel construction materials has become more and more popular since its initial introduction of codified standards in 1946. In the construction industry both structural and non-structural elements are created from thin gauges of sheet steel. These building materials encompass columns, beams, joists, studs, floor decking, built-up sections and other components. Cold-formed steel construction materials differ from other steel construction materials known as hot-rolled steel (see structural steel). The manufacturing of cold-formed steel products occurs at room temperature using rolling or pressing. The strength of elements used for design is usually governed by buckling. The construction practices are more similar to timber framing using screws to assemble stud frames.


Applications of Cold-formed Channel Steel:

1) Building frames

2) Bench frames

3) Floor framing

4) Roof

5) Trusses

6) Gates

7) Fences

8) Cattle grids

9) Scaffolds

10) Tank stands

11) Television towers

12) Car trailers

13) Rails, etc.


Structural steel shapes are suitable for a wide variety of uses.
