Background

It has additionally been demonstrated that theoretical failure of the bolts can take place at lower temperatures than the structural elements they are connecting, questioning the viability of providing equivalent protection to that on the beams and columns (studies and fire tests carried out by The Steel Construction Institute). Evidence shows that breakdown occurs through heat shock of the high tensile material which can result in premature failure of the connection.

Ongoing research involving fire engineers, material technologists, manufacturers and applicators into a method of applying an enhanced level of protection to the bolts, whilst seeking to keep within the tight cost constraints typical in the onstruction market place has led to the fire bolt cap solution.

During independent testing to BS and UL standards, the Bolt cap has demonstrated it can provide sufficient external protection to ensure the bolts remain within their limiting temperature for a period of 120minutes, addressing the growing need in multi-storey construction to meet the increasing degree of performance demanded for Eurocode structural fire engineering.

• Fully fire tested to BS476 part 20
• Easy to validate. If it’s not there it’s not protected
• An easily specified solution to critical elements of the steel structure
• A cost effective solution that can match any like system with full integrity and verification
• Very easy to handle and very quick to install
• Approved and base line specified by major architects and specifiers
• A retrofit solution to existing buildings without wet trades
• Enhanced fire safety
• Aesthetically pleasing finish for exposed steelwork
• Available in many different colours on the RAL scale
• Provides enhanced corrosion protection
• Shown to outperform alternative fire protection systems
• Quality controlled to ISO 9001:2000 and ISO 14001:2004
  

These images show the difference between a wet coated system and a bolt cap protected system after a fire.

If it's not on, it's not protected!
