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:What is the role of square toilet
16Mn Q345B 65Mn Q235B square square square square square 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
Through an angle, angle steel and steel welding, anticorrosive wood frame strip and steel bolted.
Q:How to connect with steel purlin roof
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure.
Q:How the steel columns and I-beam steel structure connection?
The characteristics of the steel is of high strength, light weight, good integral rigidity, deformation ability, it is used in the construction of large span and super high and super heavy buildings especially suitable; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness that can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; the processing of high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc..
Q:Hot dip galvanized steel can be welded
Hot galvanized square tubes can be welded.Hot galvanized pipe, welding needs to be polished galvanized layer, thoroughly remove zinc coating and oil, dust and other debris, exposing the tube itself metal color, and then welding.Zinc melting point of 419.53 degrees Celsius, low melting point, Zinc Oxide Zinc Oxide formed layer of hot combustion in high temperature welding thousands of degrees Celsius in the combustion of white smoke barrier zinc combustion, influence the flow of the weld pool of liquid metal, destruction of welding arc stiffness, the porosity, slag, weld crack.
Q:Are square steel, rectangular tube and angle steel shaped or light steel?
Belongs to the type steel, also belongs to the light steel. The question you ask is equivalent to whether apples, grapes, or bananas belong to fruit or food
Q:How to ensure the steel paint off paint
Ensure the paint off square paint method:1, the steel brush must do the clean work before painting, there is no guarantee the steel rust or grease, the steel surface cleaning is the basis to ensure the paint off.2, must use special metal paint finishing of polyester type steel, to ensure no paint brush.3, paint to ensure that the film extended evenly.
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
purposeApplicable to steel structure, shipbuilding, equipment manufacturing, equipment installation, bridge engineering, wind power generation, oil drilling platform, power construction, railway manufacturing and other fields.
Q:The moment 2mm thick galvanized square steel tube using what welding methods
If the mind zinc burning for the tube effect, can use silicon bronze gas welding, Odin 204Si, with special reference "Wiodin 204Si bronze wire in welding of galvanized plate"
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
