Fire doors are not fire doors security door security market is not chaos – fire
Went to the end of the year, went to Decoration Season, Guangzhou, security doors is a booming market. I recently visited the market understands that features doors in large numbers, any fire doors, armored doors, too numerous to mention, people get confused by the choice of candidates. In fact, many features standard anti-theft door door big hit "edge ball"??? Fire doors can really fire a few; many frequently one or two thousand dollars, armored doors, steel doors, Safety Doors, more safety very poor and thus fail to alarm results.
Market chaos Traders against each other
The veracity of the public can not
Recently, the ongoing renovation of the public Komori told the author, his many anti-theft door Yuexiu Road Sell Store in a circle, all kinds of names, see his eyes flower security door. Fortunately, no contrast, a comparison and found that businesses were against each other??? You say that I am the fire door is a fake, I say you do not use an armored door. "These features a standard door Is not it?" Komori confused.
Author to the scene to explore, find that the situation turned chaotic, there are a variety of fire doors alone, "Interpretation." The first owner of the store I recommend to the security doors with flame retardant materials are mainly stainless steel, iron and wood of three, "You see those stainless steel appliances, is not very resistant burn you?"
To a second store, the owner told buy a fire door, opening it said: "The fire doors are really expensive ah." Are fire doors would have false? Merchant laugh very ambiguous: "Many people now have to take composite doors when the fire doors sold, which in fact are the polyurethane foam."
To the third store, businesses asked: "Fire Door you need to have permits or not permit? A permit B fireproof door is 530 yuan / square meter, Class of 680 yuan / square meter; undocumented 380 yuan / square meter; composite door even more expensive 230 yuan / square meter. "
Asked a circle, the author, and Komori, like a loss.
Authoritative statement Little fire doors to fire Most metal doors without security
What kind of door in the end it really fire? For the veracity, I find the Guangzhou Institute of Quality Supervision and Inspection, Building Materials Fire Inspection Department of the responsible person to answer something of a surprise: "First of all, filled polyurethane anti-theft doors, fire must not play a role, because the polyurethane foam easy to burn, and produce large amounts of toxic smoke when burned." But the fact is that the market a lot of fire doors is filled with polyurethane foam material.
"Secondly, in accordance with the national standard for fire doors security doors can meet the demands of filling materials, there is only one kind of rock wool, rock wool, but must pay attention to the burning of toxic smoke, part of the poor quality of the wool toxicity of smoke does not reach ZA2 level requirements, are not suitable for producing fire doors. Therefore, the existence of the market function of security doors with fire, which claimed that the fill material is rock wool, as long as the same time by GB17565-2007 and GB12955-2008 standard testing, and obtain a certificate of fireproof door type, it can be considered feasible, otherwise if the lack of any of the above conditions can be considered during the concept Marketing . "
Aside fire function, frequently one or two thousand dollars, armored doors, steel doors, Safety Doors, how effective their security?
Building Fire Inspection Department officials replied: "anti-theft security doors GM technology" was April 1, 2008 implemented its anti-damage properties of security doors (including doors, Lock , Hinge), anti-intrusion performance and others have strict rules. Security doors must meet the standards, the market the so-called steel doors, entrance doors, protective doors, armored doors were "pushing boundaries" are all countries in avoiding the strict rules of security doors. Compared with the anti-theft doors, some of the metal entrance doors frames, doors and Lock Around the lack of stiffeners, stiffener section, use the rigidity of the steel is not strong, the product of poor quality, there is no fundamental guarantee of security.
"In particular, steel doors, security doors in appearance and there is no difference, but the thick steel security door, shock resistance, the implementation of the national mandatory standards; the market, most of the metal gate is the implementation of its according to their own products 'features' and the development of enterprise standards, quality not as good as security doors, security is poor, fail to alarm effect.
