7, H-shaped steel is an excellent cross-section beam mechanical performance than economy-section steel American Standard beam, its cross-sectional shape of the letters "H" of the same name. Hot-rolled H-beam flange beam width than the lateral stiffness, strong resistance to bending. Under the same size H-beam processing heavier than a light beam. 8, I-beam flange is becoming worn surface by thick web portion, the outer thin; H-beam flanges are equally worn surface 9, HW HM HN H H-beam is known as the European standard I-beam, H-shaped steel is welded system; HW HM HN hot rolled improvement Sen Jimi: It is a superior method for hot dip galvanizing process; it Sendzimir method to separate the oxidation furnace and the reduction furnace consists of a relatively small cross-sectional area of ??passage linking Such including preheating furnace, reduction furnace and cooling section, including the entire annealing furnace to form an organic whole. Practice has proved that weight I-beam, the method has many advantages: high quality, high yield, low cost, safe, etc. has been increasingly recognized. Its development speed is very fast, since 1965 a new line of work almost all adopted this approach in recent years, the old Sendzimir unit also mostly been transformed in accordance with this method.
