Hollow Sections For Constrction
A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available. HSS is only composed of structural steel per code. HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimension and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section. In the UK, or other countries which follow British construction or engineering terminology, the term HSS is not used. Rather, the three basic shapes are referenced as CHS, SHS, and RHS, being circular, square, and rectangular hollow sections. Typically, these designations will also relate to metric sizes, thus the dimensions and tolerances differ slightly from HSS. ASTM A500 Cold Formed Welded and Seamless Carbon Steel Steel Structural Tubing in Round and Shapes EN 10210 Hot finished structural hollow sections of non-alloy and fine grain structural steels EN 10219 Cold formed welded structural hollow sections of non-alloy and fine grain steels ASTM A53 used as structural steel or for low-pressure plumbing
They offer strength and are used in construction and engineering applications for their load-bearing capacity and resistance to bending and torsion force.
Circular hollow sections are used as columns and braces in portal frames structures. An example is a 114.3 x 5 CHS, which has a diameter of 114.3 mm and the wall is 5 mm thick. Similarly to RHS and SHS sections, hot rolled CHSs are made at the mill as one piece, whereas cold formed CHSs are made of a flat sheet rolled at a radius and welded. It is theirfore easy to note the difference, as the cold rolled CHSs has a weld all along its length.

Product Description: we can offer a great variety of post processing services for your reference such as galvanizing, oiled, painted, powder coated as well as plastic-coated pipe. As steel pipe is widely used in different situations, further processing is necessary. For steel pipe with plain end that is in the rough, it can form threaded on both ends, one with socket, the other with cap by deep processing. There are some other steel pipe ends for use such as beveled, swaged end, enlarged end and flattened end as well. If you have more advice or details about further processing of steel pipe, we will exert great effort to meet you. Product Feature: we can offer a variety of packing forms for you to choose such as oiled in bundles, oiled and wrapped with PVC, wrapped with PVC in bundles, painted in bundles, as well as painted with PVC wrapped in bundles. Of course, our packing method is not fixed and it can be in strict accordance with the request of our customers. For example, some customers may pay more attention to the details of steel pipe like pipe end. They require that the pipe end should be wrapped with steel strip and blocked by wood strip. Besides, steel conduit need to be wrapped in a small bundle with PVC plastic. In addition, some customers are not particular about the packing form, steel pipes can be covered just in plastic bags. Product Specification/Models: product range: 12.7*12.7-400*600,WT:0.5mm-16mm Application: speaking of orders between us, you may be having doubts about minimum order quantity. Actually, the rule of MOQ in our company is very flexible. If you want to purchase steel pipes in common specifications, our MOQ is one piece. Besides, you can also place an order including special size. The MOQ of special specification is also less than that of other companies. Therefore, if the steel pipe quantities needed in your project are not large, we are capable of meeting your requirements as long as serving your interests. Any questions, please feel free to contact with us.
