Summary     

• A building fire barrier is apassive fire protectionassembly-such as a ratedwall, floor, or ceiling-designed to compartmentalize astructure and restrict the spread of fire, heat,and smoke for a specified time period,typicallyranging from 1 to 4 hours.

• Cutting / drilling / assembly  / waterproof testing

• Very high producing rate

• Professional team & exquisite workmanship

• Considerable after sale service

• Excellent dimension rate

• Very competitive price

Application 

Compartmentation: Divides large footprintsinto distinct zones to buy time for safeevacuation.

Shaft Enclosures: Protects vertical chutes,stairwells, and elevator shafts.

Perimeter Gaps: Acts as a BuildingPerimeter Fire Barrier sealing the linear voidbetween floor slabs and exterior curtain walls.

Cavity Barriers: Closes concealed spacesinside walls or rainscreen cladding systems.

Features 

Usually, a composite structure of "flexible refractory core material+metal protective layer/support structure" is used.

Core material (core fire-resistant layer): It mainly uses aluminum silicate refractory fiber felt, which has high density and can withstand high temperatures, and is the key to the fire-resistant performance of the fire-resistant belt.

External cladding/support components (structural layer):

Traditional form: Double layer stainless steel or galvanized iron sheet is often used to sandwich the core material in the middle. This metal shell provides protection and shaping, but the hard structure may be limited in dealing with large deformations.

New Design: U-shaped Fire Barrier with L-shaped Steel Corner Support.
