In 2010, China's commercial vehicle production and sales exceeded 4.3 million vehicles, and all types of vehicles have grown in an all-round way.


In December 2010, the production of commercial vehicles was 419,500 units, an increase of 7.49% from the previous period and a year-on-year increase of 21.60%; the sales volume was 358,100 units, an increase of 0.22% from the previous period and a year-on-year increase of 15.40%. Among all commercial vehicle varieties, compared with November, the production and sales volume of passenger cars and trucks increased at different levels, the production and sales of semi-trailer tractors and non-completed passenger vehicles decreased, the output of non-integrated trucks increased slightly, and the sales volume declined slightly; Compared with the same period in 2009, the sales of semi-trailer tractors and passenger vehicles with non-integrated vehicles have declined rapidly, while the production and sales of other varieties have continued to grow, with the growth rate of passenger cars and trucks becoming more pronounced.

In December 2010, the production and sales of passenger cars reached 38,600 and 34,400 vehicles, which represented a year-on-year growth of 12.88% and 4.51%, an increase of 34.71% and 16.13% year-on-year; and production and sales of trucks were 275,100 and 243,500, an increase of 10.01% and 3.69% year-on-year. The growth rate was 20.77% and 23.26%; the production and sales of semitrailer tractors were 26,400 units and 20,500 units, which was a decrease of 13.80% and 27.50% from the previous period; the output was increased by 5.90% year-on-year, and the sales volume was decreased by 17.61%; the production and sales of passenger vehicles with non-integrated vehicles were 0.89 million units and 0.82 million units. Vehicles decreased by 3.92% and 6.78% month-on-month, output increased by 1.29% year-on-year, and sales volume decreased by 13.20%. Trucks with non-integrated trucks were sold and sold 70,500 vehicles and 51,500 vehicles. Production volume increased by 6.64% month-on-month, sales volume decreased by 1.90%, and year-on-year increase was 28.57%. 5.51%.

In 2010, commercial vehicle production was 4,367,600 units, an increase of 28.19% year-on-year; sales were 4,044.1 thousand units, an increase of 29.90%. Among them, 358,600 buses and 356,200 vehicles were sold and sold, an increase of 29.93% and 31.30% year-on-year; 2.854 million vehicles and 2.831 million were trucks, an increase of 22.72% and 25.83% year-on-year; and the production and sales of semitrailer tractors were 362,500 and 345,460. , an increase of 74.11% and 67.98% year-on-year; production and sales of non-integrated coaches for passenger cars was 88,600 and 86,900, an increase of 8.07% and 4.93% respectively; sales and sales of non-integrated trucks were 703,100 and 675,100, an increase of 36.60% and 35.53% respectively. .

Bright Steel Bar


BRIGHT STEEL BAR


Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.

peeled steel bar processing

Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.

Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.

The advantages of steel bright bars we supply:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Heat treating furnaces to adjust the mechanical properties

3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

4) Multiple packages to avoid broken packages and anti-rusty
