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:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Say so much, directly tell you, if it is with square steel (main keel), that spacing in 1--1.2 meters is absolutely no problem, the standard is not allowed more than 1.2 meters, but the actual construction exceeds the situation or some. If there is no special circumstances (such as from the wall out more than 300mm or), then no problem, rest assured!!!
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
You can't weld well without using tools, and it can't be welded with high quality. If the site is large and batch welded, you can use wood as a standard corner frame (quite a template). ), if the amount is small, you can buy a wooden triangle plate, steel square to live, post welding,
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:How to hollow square steel welding
Welding welding of thin-walled square steel, should be very careful when welding, arc welding technique should be used to pick, watch live pool, found that the weld pool collapsing must be timely arc.
Q:How to combine the paint and galvanized steel
No, as long as you choose the special galvanized steel pipe paint, mcGZ type is ok!
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:25-30mm drill pipe steel, to drill a lot, need what equipment
Square steel tube, large diameter thick walled square steel tube, square steel tube, seamless square steel low alloy square steel tube, 135*135*10 square steel tower with square steel tube, Q345B low alloy square steel pipe, seamless steel pipe 20# squareThe tube, as the name suggests, it is a square shaped tube type, many kinds of material material can form a square body, it is medium in, what, in what place, most square to steel for the majority, for the structure of the tube, decorative tube, square building.Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube, then rolled from a tube into a square tube and cut to the required length. Usually 50 bags each.
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.
Q:The anti-theft lock in the steel compression spring is what?
The development trend of suspension spring steel is to reduce carbon content, reduce decarburization tendency, and increase the flexibility and anti attenuation performance of plastic forming.
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
