M-BAR SYSTEM

“We provide high-quality products and servicesin order to fulfill the dreams of our customers and are committed to pursuing environmental friendliness and meeting our social responsibilities.”

Properties

With this system, ceiling boards can be tightly joined and the high soundproof effect can be achieved through sticking plates doubly using gypsum boards and rock wool sound-absorbing boards, in particular. This system is widely used for ordinary offices, banquet halls, apartments and expensive houses.

Quality of Ceiling Suspension

Material: Galvanized sheet iron (KS D 3506), color galvanized sheet iron (KS D 3520)

M-BAR

1. Materials of Ceiling Suspension(M-bar system)

① Phenomenon of sub-materials, stability

1) Lateral bending: Less than 2L/1,000mm
2) Curving: Less than 2L/1,000mm

② Loading strength

1) Downward load
– M-bar: Maximum deformation volume less than 10mm / residual bending quantity less than 2mm
– Carrying channel: Maximum deformation volume less than 10mm / residual bending quantity less than 2mm
2) Upward load: Maximum deformation volume less than 5mm

Materials of ceiling system (T-bar system) direct hanging

2. Materials of Ceiling Suspension (T-bar system)

① Straightness

1) Bending: 1.30mm/M
2) Deflection: 1.30mm/M
3) Twistedness: 2 /M

② Minimum load of main T-bar
