Q:What kind of material does ordinary steel plate refer to in steel market?
When we use high temperature resistant, steel plate are sometimes exposed to outdoor or there is a very high temperature, but our common plate is very weak in high temperature resistance, this is mainly because the composition of carbon and iron is very weak. But the alloy steel plate has solved this problem, because other alloy elements join, our alloy steel plate in the metal element combination aspect has obtained the very good solution.
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The good bonding between galvanized steel sheet and concrete makes the waterproof performance better. The utility model relates to a steel edge rubber water stop strip, which is characterized in that a water stopping product is adopted, which adopts a non equal thickness structure, a strong strength area and a waterproof zone, and makes the parts of the utility model be uniform and reasonable in force. The utility model relates to a steel edge rubber water stopping strip, which is additionally provided with an installation hole and is connected with the steel bar. The utility model has the advantages of firm fixation, easy displacement, and uniform and reasonable force for each part. When the utility model is in construction, the clamping surface of the clamping plate of the utility model is large and is not easy to be dislocated; the steel plate is additionally provided with an installation hole and is connected with the steel bar; the utility model has firm fixation and is not easy to displace. Good adhesion between galvanized steel sheet and concrete, and steel rubber stop makes waterproof better. A waterproof products produced by our factory in the buried steel edged waterstop is combined to galvanized steel and natural rubber raw material consisting of a rubber body material, it adopts the aging of natural rubber and excellent antioxidant performance, with strong self adhesive; high temperature in summer has no flow, low temperature in winter not the crisp; and has excellent water resistance, acid and alkali resistance and aging resistance; long service life, the product itself is non-toxic, the characteristics of a good environment.
Q:What is the difference between color steel plate and hot galvanized sheet?
Color coated substrate of galvanized plate, color coated sheet is coated galvanized plate, some color is aluminium zinc substrate, but now on the market only a few in the Al Zn substrate coated board.
Q:Who knows the wire width of the steel mesh?
Steel wire should be called stem stem.
Q:What type of welding rod is used for steel Q245R and Q235B material?
Q245R is generally used in boiler or pressure vessel, if it is a large diameter cylinder welding body in wall thickness below 8mm recommended the use of arc welding J507 welding rod, double welding, carbon arc gouging back, to obtain qualifiedQuality; when the wall thickness is thicker, submerged arc welding can be used and welding with H08MnA welding wire and HJ431 flux is used;
Q:What material is steel plate against drilling?
There is also an ordinary steel sheet drilling method: steel plate carburizing, quenching treatment, to achieve high hardness.
Q:What's the difference between single rolling steel sheet and continuous rolling steel plate?
Single rolled steel plate usually refers to medium plate, in the process of rolling and finishing, the plate has been flat, usually thicker (6mm or more), the width of the fastest up to 4800mm.
Q:How do I print the steel plate?
It's not print. It was corrosion first. It's laser engraving. Now it's 20 watts above the laser to carve the metal
Q:What is the difference between Q235A steel and Q235B steel?
Materials Q235A and Q235B belong to carbon structural steel. In the national standard GB700-88, the distinction between Q235A and Q235B material mainly in the carbon content of steel, the material is Q235A of steel, carbon content between 0.14-0.22%, Q235B of carbon content of steel between 0.12-0.20%;
Q:How is the normalized steel plate produced?
Normalizing is the process of heating a steel member to 30-50 degrees above the critical temperature and cooling it in stationary air after proper heat preservation. This process is called normalizing.
