Joist is a building material used to support shape and fix structure. It is widely used in hotels, airport terminals, passenger stations, railway stations, theaters, shopping malls, factories, office buildings, old building renovation, interior decoration, ceilings and other places. Joist is widely used as a frame and base material for decoration.
wood joist
wood joists, also known as wooden beams, are mainly made of pine, basswood, cypress, imported dry planed wood and other materials, processed into strips with rectangular or square cross-sections. wood joists are commonly used materials in decoration, with various styles, mainly used to support exterior decorative panels (such as gypsum boards, gussets, plastic steel boards, etc.), playing a skeleton role.
wood joists are easy to shape, have strong nail holding power, are easy to install, and are inexpensive. However, they also have some disadvantages, such as being not moisture-proof, easy to deform, not fire-proof, and susceptible to insect and mold infestation; the material joints are prone to cracking and may have nail holes, posing a safety hazard. In addition, due to the characteristics of wooden materials, they are also prone to deformation and other negative effects.
lightgage steel joist
As a new type of building material, lightgage steel joist has a wide range of applications. It is made of high-quality continuous hot-dip galvanized steel strip and processed by cold bending technology to form a metal frame structure for construction. It is mainly suitable for decorative shapes of various building roofs, as well as the basic materials of building interior and exterior walls and grille ceilings.
lightgage steel joists are divided into ceiling Joists and partition Joists according to their uses. The cross-sectional forms include metal angle, U-profile stud and other forms. They have better stability, higher cost performance and a wider range of applications.
The best raw material for lightgage steel joists is continuous hot-dip galvanized steel, and the galvanized layer must be very strong, with sufficient zinc content on both sides to ensure good corrosion resistance.
Installation method
There are two common installation methods: expansion bolts and nail guns. The installation of expansion bolts is to first drill holes in the building structure with an impact drill, install the expansion bolts, and then fix the angle steel on it.
Nail gun installation refers to the use of nails to secure the angle iron to the bottom surface of the building structure. When using a ceiling nail gun, you must use the appropriate nail gun and must operate it correctly to secure the angle iron to the building structure.
The suspended ceiling we install should have good load-bearing capacity to make it look more beautiful. In addition, the suspended ceiling should also be treated with rust prevention to extend its service life.
I believe that everyone now has a preliminary understanding of lightgage steel joist ceilings. When decorating, you can choose the appropriate Joist material and installation method according to your needs.
