Q:Excuse me, Shagang steel steel, what is the sign of
The two is the performance of classification (class), for example, China's current implementation of standards, (G B1499.2-2007) for steel wire for 1499.1-2008), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance of the steel branch for the 5 species; the British Standard (BS4461), also provides some level of performance test of thread steel. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment.
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words.
Q:10 less than three rebar refers to the rebar?
A grade steel is round, without ribs, elongation is the advantage, of course, it also determines its strength is lower than grade three steel.
Q:What is the difference between three - grade steel and two - grade steel?
Three grade thread steel HRB400, two grade thread steel HRB335, now the thread steel is inside the building must be less, then three grade screw steel and two grade thread steel is mainly used for what aspect, in order to solve this problem.
Q:What does it mean to have 22 4GJ on the threaded steel?
The brand of steel is expressed in terms of Arabia numerals or Arabia numerals plus English letters. HRB335, HRB400 and HRB500 are represented by 3, 4 and 5, respectively. HRBF335, HRBF400 and HRBF500 are represented by C3, C4 and C5 respectively. The name of the factory is expressed in Chinese phonetic prefix. Nominal diameter mm Arabia digital representation.
Q:Why is thread steel thinner than crude?
Reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often appear to "project inspector", to replace the steel rib steel "Choulianghuanzhu", reduce the construction cost. In the design, because the members allowed to provide "stirrup stress support", the main role is to keep the shape and location of longitudinal reinforcement, steel strapping has a smooth surface, accurate positioning, therefore, in addition to longitudinal reinforcement, licensing round steel stirrups. The longitudinal reinforcement must be made of rib steel.
Q:The difference between rebar and crescent
Rebar -- steel used in concrete structures with a generally rounded cross section and ribbed surface.Longitudinal ribs -- uniform continuous ribs parallel to the axis of the steel bar -- other ribs not parallel to the axis of the reinforcement.The longitudinal section of crescent ribbed bars -- transverse rib reinforced crescent, and does not intersect with longitudinal ribs.
Q:Are rebar bars = rebar?
Generally speaking (not absolute circle) steel is usually made of plate steel as the main form of packing, while threads are usually packed in straight strips.Turn left and turn right |
Q:What is the difference between the actual weight and the actual weight of the steel thread?
Is the difference between the work and the theory of weight. General steel factory, have weight difference, unlike canned beverage, not so accurate, this is called "bad" or "inferior". But the mills are not stupid, only under the poor, is not Quejinshaoliang, with a significant difference (such as standard 100KG, he will give you a 110KG).
Q:Why can't grounding steel be used?
The edge of the thread of the thread will have a point charge accumulation discharge, and the uniform dispersion of the ground current is unfavorable
