Marine Fireproof Door
Introduction
A marine fire door is a type of door used in marine vessels, such as ships and offshore platforms, that is designed to prevent the spread of fire and smoke in the event of a fire. Marine fire doors are constructed to be fire-resistant and are designed to withstand high temperatures, smoke, and flames.
Importance of Fireproof Structure
Ships sailing in the sea, unlike the vehicles running on shore, do not have too strong self-rescue power. Once a cabin is on fire, if there is no structural fire protection to support the separation, the fire is bound to expand rapidly.

1. The thickness of the door panel does not meet the actual requirements, and the fireproof performance can not be guaranteed. 2. Poor surface spray, affecting the appearance and is easy to rust. 3. The density of the inner filling insulating material is small, which cannot meet the fire protection requirements of A60. 4. Window is made of normal glass |
1.The thickness of the board is strictly according to the specification, and the interior is filled with high-quality rock wool board. 2.Using Q235-B steel, better toughness, better weldability. 3. The hardware is made of standard stainless steel 316, which is rust-proof and not easy to be damaged. 4.The glass is made of special fireproof glass with fireproof liquid inside.
