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.
