Usage and Applications of HRB400 Deformed Steel Bar:

Deformed bar is widely used in buildings, bridges, roads and other engineering construction. Big to highways, railways, bridges, culverts, tunnels, public facilities such as flood control, dam, small to housing construction, beam, column, wall and the foundation of the plate, deformed bar is an integral structure material. With the development of world economy  and the vigorous development of infrastructure construction, real estate, the demand for deformed bar will be larger and larger..

Packaging & Delivery of HRB400 Deformed Steel Bar:

Q:Can the end of the steel bar be inserted by the steel bar?
Chemical method of planting steel refers to the concrete, walls, rock and other materials on the drilling, and then injected into high-strength steel planting glue (Note: high-strength construction bar planting glue is roughly divided into injection type planting glue and barrel type steel planting glue two). Then insert the steel bar or section bar, glue and solidify the steel bar and the base material bond as an integral whole, it is a kind of construction technology that is more commonly used in reinforcing and reinforcing industry.
Q:Thread steel generally used for more?
Bars of 6.59 mm in diameter, most of which are rolled into strips; 1040 mm in diameter, usually
Q:How to distinguish the quality of thread steel?
The quality of threaded steel (rebar spot price) can be used to compare intuitive methods to identify, and today we teach you a few quick identification of shoddy steel small trick.1., inferior steel longitudinal reinforcement is often wavy, prone to fold. Folding is due to shoddy manufacturers in pursuit of high efficiency, the amount of pressure is too large, produce handle, a rolling produce folding, folding products after bending cracks, the strength of steel big drop.2. inferior steel appearance often pitted phenomenon. Ma is due to a defect of groove wear caused by irregular rugged steel surface. Due to the inferior steel manufacturers to pursue profits, often rolling groove rolling most standard.
Q:What is the difference between plate and steel?
Screwed steel is a kind of thread steel, refers to the steel surface spiral rib ribbed steel, steel wire like also refers to as disc together.
Q:Are thread steels of coarse steel?
The thread steel is not coarse steel and the thread steel belongs to the steel. Rough steel refers to the billet after casting steel. The billet has been rolled into various shapes of steel, including plates, profiles, tubes and so on.
Q:What does "4esg25" mean on thread steel?
The letters on the reinforcement are registered plant names or trademarks. The top figures on the bar represent the grade of the reinforcement, such as 3 for grade 2 steel, 4 for grade 3 steel, and 5 for grade 4 steel. The numbers in the back represent the specifications of the bars, and the letters between grades and specifications represent the steel manufacturer.
Q:What does "4EDT6" mean on thread steel?
It is a long strip of steel with a hollow cross section. It can be divided into round tube, square tube, hexagonal tube and all kinds of special-shaped section steel tube according to its sectional shape. According to the different processing technology, seamless steel pipe and welded pipe can be divided into two categories.
Q:What is the difference between rebar bolts and steel bars?
One is raw material and the other is finished product. Not to be confused. Shen bolt
Q:What is the specific concept of thread steel through water and what is the difference?
The principle of water cooling technology to produce rebar is that austenite can be strongly deformed in the process of continuous rolling in the recrystallization zone, resulting in very fine, strongly hardened austenite grains with a lot of defects. With the high speed of cooling on the enhanced cooling of austenite, in a very short period of time, generally not more than 0.5s, is rapidly cooled to near the phase transition temperature, inhibit the growth of austenite grain, try to keep the hardening state of austenite. When the temperature is near the phase transition point, the fine hardening austenite grains are transformed into ferrite with proper grain size under proper air cooling conditions.
Q:Sixteen mm steel, 12 meters long, a ton, how many roots?
To know how many roots a ton has, you should first know how heavy it is. From the knowledge column of Beijing dried into iron and steel, it is known that 16mm's thread steel is 1.58kg/m heavy.
