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 connect with steel purlin roof
1, if the structural part of the main steel structure is H steel or other profiles, that is, steel roof truss;2, if the structural part of the main steel structure is bolt ball or welded ball, that is the steel space truss, and steel space truss also belongs to the category of steel roof truss, but the steel grid is called more accurate;
Q:How to make the steel arc
If reinforced by 1. fold 2. arc bending machine flame cutting machine 4. fold 3. baking arc building arc roll can be solid steel grip bending machine processing.
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
Sun room in the South or the north, need to reserve the burden of snow is not the same.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Q:The water was poured into the square on how to prevent rust after treatment
Of course, all can be cloth, face sassafras. After the surface has been cleaned, it is better to put rust on the inside and outside surfaces and store them.Then is the steel material after storage should always check, if there is corrosion, corrosion layer should be removed.Finally, the corrosion of the more serious square steel, rust should not be long-term storage, should be used as soon as possible.
Q:Building with steel or steel plate?
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
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: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.
Q:The difference between the steel chrome and paint
Room heating drying paint process. The utility model has the advantages of bright color, strong visual impact, good surface finish, easy cleaning, moisture resistance and good fire prevention performance. And spray paint isJust spray it directly and let him do it naturally. This is called spray painting. How to identify paint or paint it, let us introduce.
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
