Usage and Applications of GB Standard HRB400 Steel Deformed Bar 28mm/32mm:

 

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 GB Standard HRB400 Steel Deformed Bar 28mm/32mm:

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:What are the listed companies that produce wire rod and thread steel?
It is commonly known as steel hot rolled ribbed bar. The difference between round bar and round bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs uniformly distributed along the length direction. The thread steel is a kind of small section steel, mainly used for the skeleton of reinforced concrete building member, the raw material for producing thread steel, and the carbon billet is a carbon structural steel or low-alloy structural steel which is treated by calm melting.
Q:How many roots per ton of 18 thread steel?
If it is 9 meters per point, the weight of one is 18kg, and there are 55.5 in one tonIf it is 12 meters per point, a weight of 24kg, a ton there are 41.6.
Q:JL32 is the finish thread heavy bar 32? What's the difference between normal and ordinary? What does the front JL32 mean?
Finishing rolling rebar diameter of JL32-- 32mm, 32 - screw steel hot rolled ribbed steel bars, the difference between the two: 1, ribbed bar is injected directly into the concrete, increase of steel concrete.
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
12 of the screw steel, rice weight is 0.89kg/m, 16 of the screw steel, rice weight is 1.57kg/m, with 12 of the thread steel instead of 16 of the screw steel, to the same proportion, that in dosage will be more.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:Sixteen mm steel, 12 meters long, a ton, how many roots?
The weight of that one 12m is 12*1.58=18.96kg. 1 tons =1000kg. That's 1 tons: 1000 divided by 18.96, about 52. Hope to help you.
Q:4E DG 164 is a steel grade 3 steel, DG steel, E is what mean
E is the mark of the steel band seismic! Commonly known as: with E steel, or earthquake resistant steel!
Q:What's the difference between primary and two grade steel and three grade steel?
There are two kinds of commonly used classification methods of thread steel: one is to shape classification, according to different space shapes and transverse rib rib for classification or type, such as the British Standard (BS4449), the thread steel is divided into type I and type ii. This classification mainly reflects the tightening performance of the threaded steel.
Q:What grade of reinforcement is used for cast-in-place floorslab?
Cast-in-place floors are usually made of grade two steel.Cast-in-place is relative to the precast slab, casting is to place a good template on the site, the installation of steel reinforcement on the template, and then pouring concrete on the template, and then remove the template.
