Prospect of Application Prospect of Cold-formed Steel in Building Steel Structures


Cold-formed steel, as a kind of economical section light-weight thin-walled steel, has the advantages of light weight and high strength, and is a new type of material with high efficiency and economy which is vigorously promoted and applied by the state. Foreign studies have shown that the main advantages of cold-formed square rectangular tubes (HSS) in construction and other applications are as follows:

(1) Strength-HSS has high strength-weight ratio, superior compressive characteristics and torsional resistance.

(2) Appearance - When applied in open air, HSS with circular, square and rectangular shapes has become a visual part of housing and other architectural designs.

(3) Uniformity - HSS has uniform specifications, shape, strength and tolerances, and is widely used.

(4) Simple structure - HSS is easy to bend, shape, perforate, twist or drill. Because of the application of the improved new technology, HSS is convenient and fast to use.

(5) Cost efficiency - HSS has excellent strength-weight ratio, which can greatly reduce weight and cost. The reduction in weight also means that the cost of construction, building materials and freight can be saved.

(6) Durable and strong - HSS can prevent fire, rot, mildew, termite and centipede. In recent years, with the rapid development of economic construction, cold-formed steel products will gradually be accepted by the market. Cold-formed square rectangular pipes as columns and H-section steel as beams will gradually be recognized and valued for their good seismic performance and economic advantages, and their market potential in civil and industrial buildings is great. Many domestic manufacturers are also optimistic about the market prospects of cold-formed square rectangular pipes and other open-ended cold-formed steel products for building structures. New production lines are being built. Today is our tomorrow in developed countries. Like hot-rolled H-beam products, cold-formed steel products have very broad application prospects in building steel structures.
