Light Steel Keel

What is Light Steel Keel?

Light steel keel,also referred to as light gauge steel keel,is a type of skeletal material made from lightweight steel.It is widely recognized for its light weight,high strength,good seismic performance,and the convenience of fast construction.Primarily used in suspended ceilings,partitions,and walls,light steel keel provides stable support and structural integrity to buildings.

Composition and Classification

Light steel keel is manufactured from hot-dip galvanized steel strip or thin steel plate,which is rolled by a special rolling mill in a multi-pass process.It is adaptable to various conditions such as waterproofing,shockproofing,dustproofing,sound absorption,and maintaining a constant temperature.The thickness of light steel keel typically ranges from 0.4mm to 2mm,with different thicknesses selected based on the specific use and requirements of the keel to ensure its load-bearing capacity.

There are two main galvanizing methods for light steel keels:hot-dip galvanizing,which is more expensive,and cold galvanizing,which is less costly.

Suspended Ceiling Keel:

Used for supporting and fixing indoor ceilings,divided into main keel and auxiliary keel.

Partition Keel:

Used for dividing and isolating indoor spaces,often combined with gypsum boards or mineral wool boards to create partition walls.

Wall Keel:

Used in the construction of exterior and interior walls,combined with insulation and decorative materials to form functional walls.

Ground Keel:

Used for supporting and fixing floors,often used with wooden flooring,tiles,or stone to create a flat and aesthetically pleasing surface.

Sizes and Specifications

Light steel keel comes in various sizes to meet different construction needs.

Common sizes include dimensions such as 50x50mm,75x50mm,and 100x50mm for vertical keel; 60x27mm,38x12mm,and 50x15mm for main keel; and specific sizes for ground and auxiliary keel.The thickness can vary from 0.3mm to 1.2mm,and the length is typically 3000mm,though custom lengths can be requested.

Usage in Construction

Light steel keel is used extensively in civil construction projects,light and textile industrial plants,and other areas for interior decoration,sound insulation,and other functions.It is particularly useful in creating non-load bearing wall systems that are lightweight,fire-resistant,and have good soundproofing qualities.The keel is also known for its quick installation,which speeds up construction timelines.

Material and Surface Treatment

High-quality light steel keel materials should possess high strength,corrosion resistance,and fire resistance to ensure the long-term stability and safety of the ceiling.Surface treatments like galvanizing and spraying enhance the corrosion resistance and aesthetics of the keel.

Light steel keel is a versatile construction material that offers a range of benefits,from its lightweight and high strength to its adaptability in various building applications.Its standard and customizable sizes make it a popular choice for modern construction projects around the world.
