The glass fireproof door frame is made of stainless steel, with good corrosion resistance, beautiful appearance and no rust. The glass fireproof door adopts hollow fireproof glass, which is beneficial to reduce the heat brought by the outer glass; In addition, the heat conduction of stainless steel profiles is slow after treatment, which also prevents the heat transfer to a certain extent, so as to keep the indoor temperature stable and save energy.
