Magnesium fireproof solid wood door

Product Description

This technology is a patented product researched and developed by our company in cooperation with fire protection experts of the Ministry of Public Security. It meets the fire protection requirements of the new national fire door standard [GB12955-2008], and the non-toxic and harmless thermal insulation materials meet the requirements of [GB8624-2006]. Combustion performance A1 level requirements and [GB/T20285-2006] material smoke production toxicity hazard classification ZA1 level requirements, is a new generation of new fire-resistant filling materials, with non-combustible, fire-resistant, good thermal insulation performance, water immersion resistance, environmental protection, light weight It is a material that replaces the traditional "aluminosilicate fiber material aluminosilicate rock wool" that causes damage to human health; it is an environmentally friendly alternative new product that the country has been striving to find. At present, customers in Beijing, Zhejiang, Liaoning, Jilin, Heilongjiang, Hebei, etc. use our products to produce steel fire doors and wooden fire doors, and are well received by customers.
