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

-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.

ill be more convenient for customers to distinguish them from other products.

Q:How to hollow square steel welding
Because the hollow steel thin wall, the use of electric welding should be used for small diameter with 2.5 electrodes, current should not be too large, can be around 100.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:The difference between galvanized square and galvanized steel
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
Q:What is the use of square steel keel or welding steel canopy
Sunshine board: advantages and characteristics of canopy cover top plate endurance detailed materials: flame retardant of spontaneous combustion temperature of 630 DEG C PC endurance board (wood 220 degrees C), by the national quality supervision and testing of fire building materials testing center, PC board of GB combustion (8624-1997 flame retardant grade B1), which belongs to the flame retardant engineering materials. Chemical corrosion resistant PC resistance board has good chemical resistance and corrosion resistance. It can resist all kinds of organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat resistant and cold resistant PC endurance board has good resistance to temperature difference. It can adapt to all kinds of severe weather changes from cold to high temperature. It can keep all kinds of physical performance indexes stable between -40 and 120 degrees centigrade. The photochemical PC resistance plate has the highest transmittance in visible and near infrared spectrum. Depending on the color, the transmittance is up to 12%-88%.
Q:What is the hot dip galvanized steel, production process?
Simply speakingWorkpiece: alkaline degreasing, water cleaning, acid cleaning, rust removing, water cleaning, plating aid, solvent drying, hot galvanizing, water cooling, test
Q:The difference between square and square.
Square steel, solid, of bars. Generally processed by hot rolling, deep processing can be made into round steel, anchor bolts and so on. Used to make tracks.Square pipe, hollow, belong to pipe material. There are rounded, the quality should be lighter than steel. Small diameter is generally cold-rolled, large diameter welding generally spell. Used to make structures.
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
Q:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
The rust removal on the inner wall of pipe profiles has always been a thorny problem. If the corrosion is not serious, the treatment is usually not done. If you want to anti-corrosion effect is good, but also to go inside the paint corrosion prevention practices, very few.
Q:4*4 steel welding frame tank do strong?
If you want to be firm, you can use the three and four sections. The middle slot can be clamped on the edge of the fish tank, and the tripod should be four. It's so convenient and strong!
Q:How much is the thick wall hollow square 30*30
Square: solid, bar. Different from the square pipe, hollow, belong to the pipe. Steel (Steel): material of various shapes, sizes, and properties required by pressure processing for ingots, billets, or steels.
