Product Description:

In the production of steel products, steel is molded and reshaped with different machinery at different temperatures.  One process is steel rolling, which involves metal stock passing through a pair of rolls.  Rolling produces flat steel sheets of a specific thickness, and the process is classified according to the temperature at which the metal is rolled.  If the temperature of the metal is above its recrystallization temperature, or the temperature at which the grain structure of the metal can be altered, then the process is termed as hot rolling.  If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling.

Like cold rolling, cold drawing is performed at room temperature, but instead of producing a flat object like a coke can, cold drawing makes steel into the form of a wire like the spokes of a wheel or a paper clip.  To start the process, Steel is usual hammered and rolled so that it can be fit through a die; a tool that turns the steel mass into a wire.  The room temperature steel is pulled through the die which reshapes it into a thinner shape while maintaining the same volume.  It is similar to the idea of syrup flowing out of a bottle through a tube in that it changes shape but not volume, but instead of squeezing the metal, it is pulled out.  In order to get the wire down to the right diameter, it usually requires more than one pass through different dies.

Colddrawn steel, steel covered carbon steel, excellent carbon steel, alloy structural steel, carbon tool steel, spring steel, bearing steel, tool steel, cold heading steel, free cutting steel, martensite stainless steel; products include all kinds of shapes round, square steel, hexagonal, flat steel and other conventional products, including various special-shaped steel products. In all types of colddrawn steel industry has been widely used, these areas include automotive, machine tools, furniture, standard parts, textile machinery, agricultural machinery, military industry and other industries.

The total assets of more than 40 million, as of the end of 2010 with fixed assets of 34 million, with 60 tons from 5 tons a chain drawing machine 10 sets, horizontal and inverted coiled wire drawing machine 5 sets, steel and plate production line of blasting, high-power ham stove, various straightening machine and cold rolling mill and other major equipment.

Usage/Applications

-The Square Bar is normally used as structure steel.

-Row material for other structure steel like steel angles, channels, I-beams, H-beams, etc…

Packaging & Delivery

-Packing Detail: The products can be packed in bundles by steel wires.

-Marks: We make tag marks and color marks. The tag marks with white background and red company logo will be tied up to each bundle of the products. The information is usually including basic information of products and company and other information requested by customers. As for color marks, we will paint both ends of bundles to make sure that it w

Q:Square steel and C steel which is better?
24 square meters, not ordinary sandwich panels, the proposed use of square tubes, want to secure a little, then use C steel, depending on how thick material and decided to require more detailed information, you can find me, I do color steel sandwich panels
Q:Reinforced concrete and steel stairs to do the stairs which is better
The rectangular steel tube is also not easy to makeThe stairs were made, and there was no concrete, and the stairs were steady and durable. Easy to vibrate and rust.
Q:Hot dip galvanized steel can be welded
The hot dip galvanized steel pipe has excellent atmospheric corrosion resistance, and it can easily form a protective film on the surface at room temperature, which has good corrosion resistance.When the weld is cooled, coat the weld with silver paint to avoid rusting at the weld.
Q:What is the role of square toilet
The steel is generally used in light steel structure mostly, such as steel roof, residential skeletonCommonly used structural steel according to the specifications of size for different purposes, decorative elements, assembled truss, supporting member, grid and other small pipe truss, large steel plant can be used for concrete filled steel tube truss steel column, a large stadium; another major use is round process pipeline, but in general the material and anticorrosion special requirements.
Q:The steel and wood preservative in the flower is how to connect
Or with the aid of angle steel, angle steel and steel welding, wood preservative and angle connected by bolts.
Q:It can be used as the steel electrical equipment grounding
In the electrical grounding body, generally use the steel pipe, angle steel, flat steel, round steel and other steel specially made grounding. The artificial grounding body and the ground wire form a grounding device, so that various earthing of the electrical equipment is connected with the ground through a grounding device. The artificial earthing body has two kinds of vertical embedment and horizontal embedment. The vertical buried pipe, angle steel, round steel grounding body, and have sufficient mechanical strength; ground level buried body with round steel, flat steel, common type, with several ring and radiation type. It is better to use galvanized steel when laying artificial earth in strongly corrosive soil. The steel used in the earth body shall be in accordance with the requirements of thermal stability and uniform pressure.
Q:The steel structure material can do?
First of all, will cause the waste of steel using square large section case, increase the weight of the structure, which is contrary to the steel structure of light weight advantages, small cross section from the processing, production process, the use of steel will be more, in addition to the special requirements, do not recommend the use of square steel.
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
Also, I do not know whether you are welding stainless steel or iron, the novice can press the method to do, but ripe workers are visual, direct welding, of course, visual accuracy will always be a little worse,
Q:The moment 2mm thick galvanized square steel tube using what welding methods
Galvanized square tube adopts gas shielded welding, conventional J50 gas shielded welding wireArgon arc welding galvanized square pipe, zinc burning more severe, not recommended
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
