Circular Hollow Sections
At Quality Steel, we offer you a wide range of steel parts. Whether you are looking for a solid block or a hollow section, you have come to the right place. These circular hollow sections are generally used in portal frame structures as columns of braces. They are made either as one piece when hot-rolled, or from a flat sheet rolled at a radius and welded when formed cold. This makes the two easy to distinguish, as cold-rolled circular hollow sections have a distinct welding mark.
