Steel Structure Fire Protection

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 the building collapsing.

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

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 can start to soften at around 425°C, and lose half of its strength as it reaches 650°C2.

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 workers and residents. 

Calculator and savings

Safeguarding steel buildings with effective insulation and other products is designed to save lives, rather than reduce energy consumption and associated costs. 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, its steel beams and frame.

To ensure the most effective and safe protection, our detailed fire resistance and application reports outline the best options for different builds. Contact your local office for further details. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

Case studies

The challenge

The Port of Antwerp in Belgium5 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.

Sustainability and energy efficiency

The building industry produces a third of all waste, but ROCKWOOL insulation products offer a sustainable solution. They can be removed from a building when it is renovated or demolished, and recycled into new stone wool insulation products indefinitely7.
