Many large structures – such as apartment blocks, high-rise offices and hotels – are built using a steel frame. This offers a cost-effective and stable construction option. 

However, steel structure fire protection is an essential aspect to consider when designing or renovating such a project. 

If steel is exposed to temperatures of 500°C and above, the structural integrity and stability is at risk, which could result in loss of strength of the structural steel supporting the building construction and result in collapse in the event of a fire.

An effective fire safety strategy can reduce this risk, including the installation of fire protection to steel beams and columns.

Steel Structure Fire Protection Products

Why do we need steel structure fire protection?

As steel frames often form the ‘backbone’ of buildings with a high number of occupants, keeping them safe is a high priority. Structural steel fire protection can help ensure this. 

Exposure to fire can seriously damage the frame and lead to building collapse. While it may not melt until reaching more than 1,300°C1, structural steel will begin to weaken at about 300ºC and increases rapidly after 400ºC.  At 550ºC steel loses approx. 40% of its load bearing strength.

Frequently, building fires can reach temperatures exceeding 800°C. Fire protection for steel beams and columns reduces the risk of the frame weakening and slows down the spread of fire, protecting occupants. 

Calculator and savings

Safeguarding steel buildings with effective insulation and other products is designed to save lives, as well as limiting thermal bridging and reducing acoustic transfer via vibrations through the structure. This is an invaluable addition to any construction. 

The right amount and thickness of insulation will depend on the size and specifics of the building, the load bearing requirements for the steel beams and frame.

To ensure the most effective and safe protection, our tested fire protection products can assist in specifying the correct solutions to meet your specific requirements.

Installing our specifically developed and tested fire resistance solutions will significantly reduce the amount of risk that there is not enough time for occupants to leave the building, and allow the fire brigade to control the fire without the building collapsing.

Case studies

The challenge

The Port of Antwerp in Belgium4 expanded its head office, with the aim of building a sustainable, safe and future-proofed construction.

The solution

Designed by Zaha Hadid, the quayside project included innovative and sustainable features, such as a borehole system for water cooling and heating. ROCKWOOL stone wool was also used to protect against fire risks by insulating the steel construction.

The results

Installing ROCKWOOL Conlit Steelprotect boards helped meet the highest A1 Fire Class rating, protecting employees and improving fire safety.
