Usage and Applications of 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 Deformed Steel Bar:

Packaging Detail: products are packed in bundle and then shipped by container or bulk vessel, deformed bar is usually naked strapping delivery, when storing, please pay attention to moisture proof. The performance of rust will produce adverse effect.

Each bundle weight: 2-3MT, or as required

Payment term: TT or L/C

Delivery Detail: within 45 days after received advanced payment or LC.

Label: to be specified by customer, generally, each bundle has 1-2 labels

Trade terms: FOB, CFR, CIF

Q:What does thread steel have to do with scrap steel?
There is a need to go through the processing of the construction units in the construction process of steel, for example, generally buy spiral steel to the standard 9 meters or 12 meters, the Jianshi needs 2.5 meters long 3.5 meters long and 1.7 meters long, 9 meters long steel eventually left a little cut small head these small head, or sold to a blacksmith shop, or you can only do what he can do, if he can do to the recycling of steel scrap processing.
Q:The difference between round face and round bar steel on concrete
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
Q:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
The corresponding plasticity is a little worse. In the past, most of the rebar on the site was made of two grade steel. In the past few years, the country adjusted the standard brick, and gradually used three or even four steel. Two grade steel has been gradually withdrawn from the market, many large steel mills have not been produced
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.
Q:What is the specific concept of thread steel through water and what is the difference?
Water cooling technology is used in the production of rebar, and the temperature of controlled cooling termination is higher than the recrystallization temperature of the material. If the temperature is obviously lower than the recrystallization temperature, the surface of the reinforcing steel is easy to form a thin layer of quenching and tempering structure. Quenching and tempering organization once formed, will undermine the strong cuby rebar and welding performance.
Q:Why is the difference between left and right threads? What's the difference?
The design direction of rotation screw steel, steel and related crystal. Due to crystal dislocation, under the tensile stresses along a surface slip between the crystal, for single crystal, slip surface and tensile stress direction angle of about 45, at the same time, the crystal will around the stress-induced rotation axis. According to the characteristics of steel, the surface of the reinforcement design into a spiral shape, can effectively improve the strength of steel, save materials, reduce the weight of the building. Of course, there are combined with concrete between considerations.
Q:How much is the difference between the three grade thread steel and the two grade thread steel?
For some time, due to the supply of three threads, and the two level of demand, resulting in two, more expensive than three.
Q:14 screw steel 1 meters multiple?
Classified according to geometric shapes, according to the cross section of the rib section and the spacing of the ribs for classification or classification, such as the British Standard (BS4449), the thread steel is divided into type I, type ii. This classification mainly reflects the tightening performance of the threaded steel.
Q:Why does the steel thread have longitudinal ribs?
The main function of the longitudinal ribs is the force to improve the performance of the transverse ribs, the stress of support surface transverse rib in the longitudinal direction, reducing flange stress concentration, so as to improve the mechanical strength of the reinforced rib, deformation of bond between concrete and steel reinforced concrete, the collaborative work and better.
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.
