Product Description:

1. Structure of Hollow Section Description: 

Hollow section is a type of metal profile with a hollow tubular cross section. Hollow section, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular hollow section have very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes them good choices for columns. They also have excellent resistance to torsion. Hollow section can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural shape for this application. However, the hollow section has superior resistance to lateral torsional buckling.



2. Main Features of the Hollow Section: 

• High manufacturing accuracy

High strength

Small inertia resistance

Strong heat dissipation ability

Good visual effect

Reasonable price

Q:What are the main aspects of precision steel tubes?
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling.
Q:What type of steel pipe for security windows?
Stainless steel security window generally use 25 square tubes and 19 round tubes! 25/38 tubes and 22 round tubes are also available!
Q:What's the difference between straight steel pipe and seamless steel pipe?
Seamless steel pipe and welded pipe are separated because of different production process. Seamless steel tubes include hot rolling, cold rolling, cold drawing, and other rare, such as cold extrusion.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
Q:What quota should be installed for heating seamless steel pipe?
Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;
Q:What does "HBB" glass steel pipe mean?
The utility model has the advantages of high strength, light weight, no deformation, smoothness of the inner surface, etc.. The friction coefficient is small, the cable is light and smooth, and the cable is not damaged. The weight is only 1/4 of the steel tube, and the 1/10 of the concrete pipe can be moved by one person. The transportation is convenient and the construction is simple and convenient.
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
