Zusammenfassung:	The utility model discloses a light steel keel comprising a base plate and a U-shaped keel body with two sides provided with bayonets. The light steel keel is characterized in that concave and convex pocking marks are disposed on the surface of the U-shaped keel body in an oblique and parallel mode, an arc rib is arranged on the base plate, the concave and convex pocking marks are in staggered, uniform and obliquely parallel arrangement on the whole surface of the keel body with an oblique degree of 45 to 60 degrees, and the arc rib is arranged on a central axis of the base plate and with the length the same as that of the keel body. Compared with the prior art, the light steel keel has the advantages of being simple in structure, easy for self-tapping screws to be mounted and fixed, hard to slip and deform and capable of effectively improving carrying capacity of the keel and work efficiency of the installation.
