Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
Q:The 8 thread can replace the beam stirrups by steel
Fixed beam and beam is set in the stirrups stirrups, stirrup stirrup is higher than that of the non quota subheadings subheadings, because all trouble making and binding stirrups. In addition, need to see which parts of the ring beam.
Q:The two project is to use rebar or rebar?
Of course, depends on what steel is used for components, such as the two structure of the structure column, and other minor parts, it does not matter. Suggest a slightly larger span of the floor, do not use round steel bar, or the use of thread steel bar, and then with anti crack steel.
Q:Could you tell me what is the difference between steel pipe and round steel?
The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:How many tons of pressure can the round steel of 70 inches bear?
As the diameter of about 11.5 cm diameter 180 cm long in the middle of the force which kind of force will be smaller if the curvature is hollow capability hollow wall thickness to achieve much greater strength than solid to do not understand what the best please say a little more thank you good answer is a plus
Q:Round bar, flat steel, not reinforced?
Flat steel: can be used to make iron, tools and machinery parts, building used as housing structure, escalator.All belong to section steel. Round steel can be used as reinforcing steel, which is often referred to as light round bar and primary steel. Flat steel is finished steel, not steel.
Q:What is hot rolling? What is called forging?
Forging is a method of processing wool embryos by plastic deformation. They are also classified as cold forging and hot forging
Q:Are lightning checks required for galvanized steel, flat steel and round steel?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
Q:The problem of dowel bars on concrete pavements?
The left and right half of the casting, the middle of the set is a longitudinal pull rod, tie rod settings and your panel thickness and plate width, length of the boardTo Portland cement concrete surface layer as an example: when the plate is 3M, the thickness of the surface layer is 200-250mm, the rod Phi 14 * 700mm * 900mm rebar length and spacing from the lateral transverse joint distance not less than 10mm (mean distance is a piece of plate length is 4 meters to the two plates the net is not small 100mm).
Q:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
