1.Q345D槽鋼是截面為凹槽形的長條鋼材。其規格以腰高(h)*腿寬(b)*腰厚(d)的毫米數表示，如120*53*5，表示腰高為120毫米，腿寬為53毫米，腰厚為5毫米的槽鋼，或稱12#槽鋼。腰高相同的槽鋼，如有幾種不同的腿寬和腰厚也需在型號右邊加abc 予以區別，如25a# 25b# 25c#等。

1.Q345D channel is a cross-section of the groove-shaped strip of steel. The specifications to waist high (h) * leg width (b) * waist thickness (d) of a few millimeters, such as 120 * 53 * 5, which means that the waist height of 120 mm, leg width of 53 mm, waist thickness of 5 mm slot steel, or 12 # channel. High waist same channel, if several different legs wide and thick waist also need to model the right plus abc be different, such as 25a # 25b # 25c # and so on.

3Q345D槽鋼分類及用途

3Q345D channel classification and uses

Q345D槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規格為5-40#。經供需雙方協議供應的熱軋變通槽鋼規格為6.5-30#。槽鋼主要用於建築結構、車輛製造和其它工業結構，槽鋼還常常和工字鋼配合使用。

Q345D channel sub-channel steel and light channel. Hot-rolled channel steel specifications for the 5-40 #. The agreement between the supply of hot alternative channel specifications for 6.5-30 #. Channel is mainly used for building structures, vehicle manufacturing and other industrial structures, channels and beams often used in conjunction.

4.Q345D槽鋼按形狀又可分為4種：冷彎等邊槽鋼、冷彎不等邊槽鋼、冷彎內捲邊槽鋼、冷彎外捲邊槽鋼

4.Q345D channel according to the shape can be divided into four kinds: Cold equilateral channel steel, cold-formed equilateral channel steel, cold-formed channel within the curling, curling channel cold outside

5.依照鋼結構的理論來說，應該是Q345D槽鋼翼板受力，就是說槽鋼應該立著，而不是趴著

5 according to the theory of steel, it should be Q345D wing channel by force, that channel should be standing instead tummy
