I am looking for the fire resistance of the building components, see the middle of the house wall with "steel keel" and "light steel keel", what is the difference between the two?
What do I want to know is that the two are different in terms of function and practical application? What are the advantages and disadvantages?
Light steel keel is used to ceiling the ceiling, and steel keel is a kind of iron frame, the cost is relatively high, to do the effect of quality than the light steel keel expensive, almost more than light steel keel on your 40%
However, steel keel is made of pure steel, heavier weight, nature and light steel keel almost, is the difference between materials, light steel keel is a thin steel plate, steel keel is built with pure steel.
Light steel keel is galvanized steel or thin steel plate by a special rolling mill by multi-channel rolling process, section U-shaped, C-shaped, T-shaped, L-shaped. Mainly used for the installation of various types of gypsum board, calcium-plastic plate, sound-absorbing panels, etc., for indoor partitions and ceiling keel bracket. Compared to wood keel, with high strength, fire, moisture, easy to construction and so on.
