Cold drawn steel bar is produced by hot rolled steel bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
According to different steel grade, the production line is usually different. The Basic production line is as below:
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty

In the coldest winter of the market, the heavy truck Big Three, Foton Motors, China National Heavy Duty Truck and Dongfeng Motor announced in succession in the 2012 annual report that operating income and net profit fell sharply. However, with a higher proportion of non-operating income, the three major companies barely suffer losses.
The reporter noticed that after unveiling the “figure†of non-recurring gains and losses, the net profit of the heavy truck giants attributable to the shareholders of the listed company was not so good, and both were losses. Relying on government subsidies or asset sales to resist the decline in the main business will not be sustainable.
Heavy truck is most injured
Affected by the macro economy and overcapacity, the profits of domestic commercial vehicle companies fell by 5.49% last year. In particular, heavy trucks suffered the crisis of the whole industry, which was a decrease of 27.78% year-on-year, ranking the highest in recent years and ranking first among all models. Heavy truck giants' annual report also confirms this point, in which the two companies’ net profit declined by nearly 90% or more last year.
On March 30, the 2012 annual report released by Foton Motor showed that last year, Foton Motor achieved operating revenue of 40.973 billion yuan, a year-on-year decrease of 20.66%, and net profit of 1.353 billion yuan, a year-on-year increase of 17.43%. It is worth noting that the operating income of medium and heavy trucks was 12.356 billion yuan, down 51.48% year-on-year; sales of 95,517 vehicles were down 12.6% year-on-year.
China National Heavy Duty Truck Annual Report 2012 shows that last year the company achieved operating revenue of 27.889 billion yuan, down 23.8% year-on-year; net profit of 171 million yuan, down 85.4% year-on-year. Sales of 90,300 heavy trucks decreased by approximately 30.5% year-on-year; 32,200 light trucks were sold, an increase of 46.7% year-on-year.
According to the 2012 annual report of Dongfeng Motor, the company achieved operating revenue of 17.7 billion yuan last year, a year-on-year decrease of 17.26%; net profit of 21,734,200 yuan, a year-on-year decline of 94.82%.
Non-campaign revenue surged against the market
On the face of it, the three giants had positive net profits last year, and they seemed to resist the winter of the market. However, in reality, the three major giants’ main business operations are not able to make ends meet. The profit structure is also not reasonable. The disposal of non-operating income such as assets and government subsidies has become their life-saving straw.
After deducting non-recurring gains and losses, the net profit attributable to shareholders of the listed company of Foton Motor was -8.008 billion yuan, a year-on-year decrease of 196.35%. In the same period, non-operating income was 2.727 billion yuan, a year-on-year increase of 578.26%.
The government subsidy is even more helpful to Dongfeng Motor and China National Heavy Duty Truck. Dongfeng Motor received a government subsidy of 330 million yuan during the reporting period, resulting in non-operating income of 346 million yuan during the same period, a sharp increase of 76.92% year-on-year. After deducting non-recurring gains and losses, the company's net profit was -2.85 billion yuan, down 220.75% year-on-year.
During the reporting period, Sinotruk received government grants of 428 million yuan, an increase of 341.24% year-on-year.
An auto analyst at a securities company in Beijing told reporters that non-recurring gains and losses did not have much to do with the company's main business and was occasional. The proportion of non-operating income is too large, indicating that the heavy truck companies have not yet reached the bottom. The real recovery depends on when their main business will resume.
Highlights in overseas markets and LNG heavy trucks
The heavy truck giant's annual report is not without bright spots. The plight of the domestic market has led the heavy truck giants to increase their efforts to open up overseas markets and achieved remarkable results.
Foton Motor exported 44,300 vehicles last year, an increase of 21.95% year-on-year; export revenue reached 3.62 billion yuan, an increase of 70.46% year-on-year.
Heavy trucks in China exported 26,500 heavy trucks, an increase of 27.1% year-on-year; export revenue reached 7.202 billion yuan, a year-on-year increase of 22.9%, and continued to rank first in domestic heavy truck industry exports.
The reporter also noted that this year, Foton Motors and China National Heavy Duty Truck Co., Ltd. will focus their efforts on the Sino-foreign joint venture platform. The strategic alliance between Foton, Daimler and Cummins has enabled Foton Motors' export growth to be robust.
The cooperation between China National Heavy Duty Truck and Mantech Co., Ltd. has been released in batches. China National Heavy Duty Truck Group proposed that it will increase its efforts in international market development this year, develop emerging markets such as South America, and establish overseas KD factories to achieve localization of production.
In addition, under the heavy down market, heavy truck giants have adopted new energy vehicles as the development direction of commercial vehicles. In particular, LNG heavy trucks are becoming new strategic products. Last year, Foton Motor sold nearly 3,000 new energy vehicles of various types, including more than 600 LNG heavy trucks. On March 12 this year, Foton also announced the signing of a sales contract for 60 Auman LNG LNG trucks (9-series tractors).
China National Heavy Duty Truck frequently referred to LNG heavy trucks in its 2012 annual report, saying that its T12 natural gas engine performed well.
