Fire Rated, Intumescent & Cementitious Paint for Steel

Fire Retardant Coating


Ace Steel Master VM provides structural steel fire coating. It imparts fire resistance and heat insulation to prevents sudden collapse of the steel structure because of fire.

The phenomenon of possible sudden collapse of steel structures in fire conditions is based on the fact that steel loses near 50% of its mechanical strength at a temperature of 550°C. For a normal fire, it takes 5 to 6 minutes to reach this level of temperature which can result in sudden collapse of the a steel structure. When all the exposed surface of structural steel is coated using Ace Steel Master VM system fire rating up to two hours is possible.

Special Features

Ace Steel Master VM system is stable in its performance against fire even after long exposure to various expected challenging conditions like exposure to weathering effects, ageing, vibrations, temperature variation and water logging.

Whenever modifications like additions and/or extensions to existing structures is desired it can be easily done to that part of the structure and using regular materials of the system and nominal maintenance techniques the system can be restored to desired performance level.

  • Ace Steel master has excellent adhesion to most structural steel surfaces and the conventional primer and paint systems in commercial and industrial establishments
  • The system can become paintable with primer
  • Non Toxic
  • Does not evolve halogen when exposed to fire
  • Ecologically harmless
  • Countable to green building materials
  • The system is not prone to attacks by vermin, termite or rodents
