Q:What is the maximum tensile force of 25 thread steel?
The specific parameters of common thread steel are:HRB335: yield strength: 335Mpa, tensile strength 445Mpa, elongation: 17%HRB400: yield strength: 400Mpa, tensile strength 540Mpa, elongation: 16%HRB500: yield strength: 500Mpa, tensile strength 630Mpa, elongation: 15%Ji'nan permanent thread steel tensile strength testing machine, Ji'nan permanent thread steel tensile test machine,
Q:What grade of reinforcement is used for cast-in-place floorslab?
Compared with the floor slab, the cast-in-place concrete can strengthen the integrity and the seismic resistance of the building, and has greater bearing capacity. At the same time, in insulation, sound insulation, waterproof and other aspects also have certain advantages.
Q:What is hot rolled coil? Hot rolled coil relative to thread steel and other steel, is not considered a higher point?
A hot rolled coil is a flat, flat material that is rolled by a billet at a certain temperature.
Q:What are the specifications of thread steel?
Specification requirements for threaded steel shall be specified in the import and export trade contract.Generally should include the standard grade (type code), the nominal diameter of steel, nominal weight (quality), the length of the specifications and the allowable difference between the above indicators.
Q:What is the difference between the II and III grades of threaded steel?
Third grade rebar than ordinary II rebar strength increased about 20%, is designed for building construction of reinforced structure is developed, the yield strength of 400Mpa (grade HRB400), is the country to promote the use of excellent products.
Q:12 how much is one ton of thread steel?
If it is hrb400e three grade rebar, then 12 of the meter price is 2.07 yuan; if it is hrb50 four grade rebar, that 12 of a meter price of 2.23 yuan.
Q:How to calculate the theoretical elongation of finishing thread steel?
Rebar is a kind of special bar with discontinuous external thread. The steel bar can be connected or anchored at any section with a connector or anchor with internal thread.
Q:Are rebar bars = rebar?
Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
Q:How to recognize high quality thread steel
When we buy rebar, we should not only look at the size of the thread steel, but also use the vernier caliper to measure whether the size meets the requirements. A lot of times, inferior thread steel through the flat flat way to deceive the buyer's vision, so from the steel reinforcement to observe the end of the steel is flat oval, meet the requirements of the thread steel is basically round.
Q:What's the difference between primary and two grade steel and three grade steel?
There are two levels of steel rebar, three steel, four steel grade difference, no grade steel, there are a lot of customers to wire (round) mistakenly called a steel. At present, China is gradually out of grade two steel, four steel grade two steel grade HRB335, three grade steel grade HRB400, four grade of steel wire is HRB500, (Pan Yuan) new material grades are HPB195, HPB235, HPB300, old wire material grades corresponding is Q195, Q235.
