Channel steel is a long strip of steel with a groove-shaped cross section, which belongs to carbon structural steel for construction and machinery, and is a section steel with complex cross sections. The specifications of channel steel are mainly represented by dimensions such as height (h), leg width (b), waist thickness (d), etc. The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is stipulated in the corresponding standards. The price of channel steel is mainly affected by factors such as market demand, cost, specification, and process. The price of channel steel is about: 620-700 US dollars / ton.


1. Introduction of channel steel

Channel steel is a long strip of steel with a groove-shaped cross section, which belongs to carbon structural steel for construction and machinery, and is a section steel with complex cross sections. The finished channel steel is delivered in the state of hot forming, normalizing or hot rolling. Channel steel can be divided into four types according to the shape: cold-formed equal-edge channel steel, cold-formed unequal-edge channel steel, cold-formed inner-curled channel steel, and cold-formed outer-curled channel steel. Channel steel has good welding, riveting performance and comprehensive mechanical properties. Therefore, channel steel is widely used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing and other fields.

2. Specifications of channel steel

The specifications of channel steel are mainly represented by dimensions such as height (h), leg width (b), waist thickness (d), etc. Channel steel specifications range from 5#-40#, that is, the corresponding height is 5-40cm. The import and export order of channel steel is generally based on the specifications required in use after determining the corresponding carbon steel (or low alloy steel) steel grade. The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is stipulated in the corresponding standards.

3The price and influencing factors of channel steel

The price of channel steel is mainly affected by factors such as market demand, cost, specification, and process. Its price is about: 620-700 US dollars / ton.

(1) Market supply and demand

The price of channel steel is affected by the relationship between supply and demand in the market. Factors such as the limited production of the steel industry will have an impact on the supply and demand of channel steel. When the supply is reduced, the demand is large, and the supply and demand are tightly balanced, the price of channel steel will rise; Prices will drop.

(2) cost

The cost factors that affect the price of channel steel mainly include raw material cost, energy cost and labor cost. Changes in iron ore prices are key factors affecting steel prices. In addition, steel production also consumes a large amount of public media such as coking coal, water, electricity, gas, oil, etc., and consumes manpower, machinery and equipment, etc. Changes in the individual costs of these required materials will affect the market price of steel.

(3) Specifications and models

The price of channel steel is affected by the specification and model. Channel steel sales are generally calculated by ton, and the weight of channel steel of different specifications and models is different, and the price is naturally different. Secondly, the production process of channel steel is also one of the important factors affecting the price of channel steel.
