And it shall be tied with the vertical pole to tighten the horizontal pole. Structural requirements for square pipes: when the erection height exceeds 40m and there is wind vortex effect, the structural requirements for square pipes shall conform to the following rules: 1. The longitudinal distance and step distance of degree poles of single and double row square pipes shall not be greater than 2.1m, and transverse diagonal braces shall be set. 2. The upper part of the top layer of the portal frame, the setting layer of the wall connecting parts, and the protective shed

Introduction to rectangular tubes: There are two main consumption modes of rectangular tubes, namely, cold rolling and hot rolling. Rectangular tube hot rolling is made of hot rolled strip steel after processing. Cold drawn or cold rolled fine rectangular tubes. Cold rolled rectangular tubes are cold drawn or cold rolled fine rectangular tubes with high dimensional accuracy and good external brightness for mechanical structures and hydraulic equipment. Cold drawn rectangular tube is used as the starting material

How to distinguish between hot-dip galvanized square tube and cold galvanized square tube: galvanized square tube is divided into hot-dip galvanized square tube and cold galvanized square tube in terms of consumption technology. It is precisely because the addition of these two galvanized square tubes is different that they have many different physical and chemical properties. Generally speaking, they are different in strength, toughness and mechanical properties. The square tube manufacturer will take you to understand. Hot dip galvanized square

The influence of temperature and time on the performance of square tube: at the same time, the heating temperature and time will also have a great impact on the performance of square tube. During the operation of circular furnace, the technical regulations should be strictly followed. The influence of temperature and time on the performance of square tube should be checked frequently. The billet of square tube will be burned and decarburized, In order to ensure the stability of piercing performance and chemical properties of square tube billets

Square tube is a hollow square thin-walled steel tube, also known as steel cold-formed profile: it is a profile steel with square section dimensions made of Q235 hot-rolled or cold-rolled strip steel or coiled plate as the base material after cold bending and forming, and then high-frequency welding. Hot rolled extra thick wall square tubes are subject to cyclic loading except for wall thickening. Glass curtain walls, automobile chassis, solar power generation supports and many machine parts are subject to cyclic loading
