Steel protection spray NSW is a fire protective technique to delay the collapse by insulating the steel structure (in columns, beams, floors and roofs) that supports the building. Passive fire protection materials insulate steel structures from the effects of the high temperatures caused due to fire.
The most widely sprayed fire protection materials for steel protection are mineral fiber and other cementitious materials. Steel protection spray NSW is sprayed directly onto the contours of beams, columns, girders, and floor/roof decks.
Why Intumescent paint better?
Intumescent paint NSW allows you to display the original profile of the steel, alongside protecting the structure in the case of a fire. In Greyton's recent works at the Sydney Theatre project and the Shore apartments in Walsh Bay, Hickson Street, we were able to restore cast-iron columns imported around the turn of the century, maintaining the intricate lacework and column capitals.
Intumescent paint NSW represents an increasingly used way to provide passive fire protection to steel structures with modern architectural design in industrial and commercial buildings.
There are various advantages of Intumescent coating on steel structures:
• It does not alter the intrinsic mechanical properties of the materials.
• It is conveniently processed.
• It has different versions that are usable on distinct materials such as steel, timbers, composite elements and concrete.
How Intumescent Paint becomes useful for Passive fire protection?
Intumescent Paint NSW is a reactive coating that expands due to fire heat. It swells many times of its original thickness to produce a carbonaceous char, formed by numerous small bubbles. It thus acts as an insulating layer to protect the substrate. Fire-rated Intumescent Paint can improve the fire rating of steel structures by one or many two hours.
Fire Rated Intumescent Coating is the most commonly used coating to protect steel structures in buildings where flexibility and aesthetics are imperative.
How to apply Intumescent paint on steelworks?
An Intumescent paint system will include a primer and a topcoat.
The purpose of a primer is:
• Adhesion to the substrate in the normal state.
• Anticorrosion protection and the ability to stick to the char formed due to fire exposure.
The purpose of a topcoat is:
• Serving as an aesthetic function
• Serving as a sealer function in case of aggressive degradation
• Promoting weathering resistance.
For speed and quality of finish, Intumescent coatings are preferably spray applied with airless paint equipment.
A word of Caution
Before applying the Steel protection spray NSW ensure that the Structural steel column and beam are
• clean and dry,
• free from dust, oil, loose mill scale or rust,
• Or any other condition that can prevent good adhesion and blast cleaned as per proper international standards.
If there unfavorable weather conditions, such as high humidity, specific topcoats are useful.
Steel protection spray NSW delays a collapse, and buys more time for the safe evacuation of people from the building. It also ensures that the building doesn't collapse by the time Fire Brigades and NSW Rescue teams arrive. Thus, it fulfils all the requirement of a robust Passive Fire Protection: protect the structure, save lives, and buy time for fire extinguishing and safe evacuation.
