Depending on the methods of use, rectangular pipes are produced as follows: cold-formed. In this category, popular furniture pipes. They are produced from carbon and low-carbon steel grades on special equipment for high dimensional accuracy. Advantages: high surface quality and regular shape, hot-formed, general-purpose electrofusion. Low cost and average strength values, electrowelded closed construction. Only high-carbon steel grades are used (strength class not lower than K360). Our company guarantees an individual approach to each client. For purchase or consultation, call the specified number. PIPES WITH A SQUARE SECTION In such pipes, the cross section is not round and can be square, rectangular or oval.
