Under the current situation of great pressure in the domestic market and the increasingly close global trade, many domestic fire door manufacturers are eager to expand overseas and seek new opportunities. The US market, with its huge consumption scale and mature construction industry system, has attracted the attention of numerous fire door manufacturers. However, to enter this market, a crucial "admission ticket" is indispensable - UL10B certification.

The United States has its own certification system, UL certification. UL (Underwriters Laboratories), as a globally renowned safety science company, is widely recognized for its professionalism and credibility in the fields of product safety standard setting and testing evaluation. American consumers and regulatory authorities have great trust in the UL certification mark, and fire doors with the UL label naturally have the aura of reliable quality.

The United States has extremely detailed and strict building regulations. Chapter 7 of the International Building Code (IBC) stipulates strict requirements for fire separation in different types of buildings and different areas. For example, in high-rise commercial buildings, fire doors with high fire resistance performance must be installed between evacuation stairwells, elevator shafts and other areas on the floor to prevent fire and smoke from spreading rapidly to the vertical transportation hub and trapping the escaping crowd. Such fire doors are required to pass authoritative certifications such as UL 10B to ensure the minimum fire and smoke resistance duration and structural stability. The specific fire resistance rating of fire doors is determined by factors such as building height and personnel density, ranging from 1 hour to 3 hours.

The series of standards such as NFPA 101 "Life Safety Code" issued by the National Fire Protection Association (NFPA) also require the installation of compliant fire doors at the boundaries of key fire compartments. UL 10B certification has become a common means for manufacturers to prove that their products meet the standards.

The insurance system in the United States is prevalent, and commercial insurance companies have strict requirements for the fire protection facilities of insured buildings in order to control the risk of compensation. Installing fire doors certified by UL10B can enable enterprises to obtain more favorable premium rates when insuring. On the contrary, non-compliant fire doors may cause enterprises to face the dilemma of soaring premiums or even being refused insurance. This makes property owners and construction contractors prefer to choose fire door products with certification guarantee.

Therefore, manufacturers must consider the necessity of UL10B certification.
