Intumescent coating

What is intumescent coating for steel?

Intumescent coating for steel is a specialised surface treatment method used to improve steel’s resistance to fire. This type of paint is applied to steel surfaces and has unique properties that activate when exposed to high temperatures during a fire.

How does intumescent coating work?

Intumescent coating is designed to react to heat and protect steel in critical situations. The process works as follows:

Thermal insulation: When the coatinging is exposed to extreme heat, it expands and forms an insulating foam layer that prevents the steel from heating up quickly.
Extending the steel’s load-bearing capacity: Steel loses its strength at temperatures above 500 °C. Intumescent coating delays this heating, allowing the building to maintain its stability for longer during a fire.

Applications

Intumescent coating is often used on steel structures in buildings where fire safety is critical, including:

Industrial buildings
Commercial properties
Public buildings
Infrastructure projects

Why choose powder coating for steel?

Powder coating is a specialised process in which the coating is applied and cured at high temperature. The benefits of this method are:

Exceptional durability: Creates a strong, hard-wearing surface that can withstand both physical wear and harsh weather conditions.
Smooth, uniform finish: Oven curing provides a professional surface without runs or unevenness.
Long-lasting protection: Resistant to chemicals, UV rays and moisture, extending the service life of the steel.
Meets industry standards: Many industries require powder coating to ensure quality requirements for the coating layer, especially in construction and industry.

By combining sandblasting and powder coating, you get the best possible solution to ensure both durability and aesthetics for your steel components. This is particularly important for items that must withstand demanding environments.
