Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing is zinc plating, the general surface is relatively smooth, no zinc flowers, there are two kinds of resistance to fingerprints and non - Fingerprint
Q:How long are the seamless tubes? Are they six meters long?
The length of the seamless tube is 3000~12000mm, including 6 meters.
Q:What does the diameter of a steel pipe project mean?
Nominal surface meaning can be understood as a public address. It's as if everyone agreed to call something as a "devil", and he was the devil.Don't be confused by the numbers behind the nominal diameter. For example, DN50, this 50 is really close to the outer diameter or inside diameter of the steel tube, but DN50 is only a general model of the caliber of the national standard.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The scaffold is also called full house scaffolding is a construction process for building a scaffold. Hall scaffolding relative to other scaffolding system density, that is, the house full of shelves. The full scaffolding is more secure than the rest of the scaffolding.
Q:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
Galvanized steel pipe is commonly known as "cold plated tube", using electroplating process, only galvanized steel pipe in the outer wall, the wall of the pipe is not galvanizedHot dip galvanized steel pipe adopts hot-dip galvanizing process, and the inner and outer walls of the steel pipe have zinc coating.
Q:What does "steel pipe SC" mean?
SC is an ordinary welded pipe, equal to water professional DN, SC is welded steel pipe concealed, general pipe wall is relatively thick, S represents pipe material, C represents laying mode, TC stands for wire pipe concealed, pipe wall is thinner.
Q:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
