Fire Retardant Paint for Structural Steel
Fire Retardant Paint for Structural Steel: Fire retardant paint for structural steel is a specialized protective coating designed to delay the impact of fire on steel structures, helping maintain their strength and stability during high-temperature exposure. It is widely used in buildings, factories, warehouses, bridges, and industrial plants where steel is a primary structural material. 🔥 What is Fire Retardant Paint? Fire retardant paint (often called intumescent coating) is a chemical-based paint that reacts to heat and forms a protective barrier on steel surfaces. Its main purpose is to slow down heat transfer and delay structural failure during fire incidents. ⚙️ How It Works When exposed to high temperatures (around 200–250°C), the paint undergoes a chemical reaction: Expands 50–100 times its original thickness Forms a thick insulating foam (char layer) Reduces heat reaching the steel surface Keeps steel below critical temperature for longer This process delays the point a...
