Q:Why is the earthing device forbidden to use thread steel instead of round steel as lap steel bar?
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.
Q:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
Double reinforcement should be adopted for roof bar reinforcement.(5) double deck two-way steel bars shall be installed in cast-in-place slabs with a thickness of more than 120mm.
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:Difference between round bar and threaded steel in use
The rebar is much higher than the ordinary, and the low carbon steel rounds are much higher. The heat treated steel is much stronger than the low carbon round steel, nearly twice or even higher.
Q:What are the marking of the steel bars on the mills? Which factory is the 2LG16 thread?
2LG16 thread manufacturer is the Laiwu iron and steel works, referred to as "Laiwu Steel", the letter "LG", indicating that the steel produced by the diameter of 16 of the two grade thread steel.
Q:What is the diameter of the cross section of the threaded steel?
There are many ways to measure diameter. Different methods are adopted according to different precision requirements,The simplest method is to use the scale directly, and the longest line through the section is the diameter. This method has the lowest precision
Q:Why is thread steel thinner than crude?
Thread steel is used for the construction of reinforced concrete facilities, his material is generally low alloy steel grades is generally 16Mn (16 Mn low-alloy steel), or 45 carbon just, their yield strength is above 350Mpa, tensile strength 500Mpa, low carbon steel round steel than ordinary much higher (after heat treatment of the steel strength than low carbon steel nearly twice as high or higher)
Q:What does "4esg25" mean on thread steel?
4esg25 these are the basic information of reinforcement, equivalent to the identity card information. Represents grade four steel (HRB500), and ESG represents the modulus of elasticity of the reinforcement in the reinforcement; then the nominal diameter is 25.
Q:Why is round bar more expensive than thread steel?
Round steel has a wide range of applications, many brands and different uses. Such as machining, shipbuilding and other user processing requirements are also different. Such as alloy round steel, Q345B, high carbon steel, 45#, 35#, general round Q235B, mainly material, ingredients, etc..
Q:Is the steel thread stainless steel?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; the corrosion (acid, alkali, salt and other chemical etching) steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
