Blast protection structures

ranging from entire buildings, or secure areas within a building, to individual blast walls. The unique ‘Surefast’ ‘slot and lock’ connection system facilitates the rapid assembly of Bi-Steel structures on site with minimum disruption.

Buildings constructed with blast resistant Bi-Steel can be erected quickly, accurately and with minimum disruption – and they offer the highest levels of protection against explosive attack.  Bi-Steel panels are manufactured in a dedicated Corus plant, then fabricated into modules, which are transported to site where they are quickly assembled and filled with ready-mixed concrete. This rapid method of construction enables secure, blast resistant buildings to be created quickly and cost efficiently.

Creating a blast resistant citadel area within a sensitive building to provide added protection for critical building services, IT or communications equipment, control centres, data storage, etc, can be achieved by constructing in Bi-Steel. This higher integrity area can be easily incorporated into the structure when it is being built, or it can be retro-fitted within an existing building if the need arises at a later date.

Part or complete structures utilising interconnecting internal and/or external walls and slabs can be designed in Bi-Steel and supplied for either permanent or temporary applications.  A number of different connection systems can be used to join Bi-Steel panels, ranging from welding to mechanical connections. Our engineering team will advise on the most suitable approach depending on the structural type, loading and associated level of protection required.

Bi-Steel blast walls have been installed in hours compared with weeks for reinforced concrete alternatives.  Simple construction has allowed Bi-Steel to be used easily in applications with very limited space and access restrictions.  Blast walls can also be clad to provide a pleasing external façade for architectural or security purposes.

Surefast is a unique system developed to facilitate the rapid assembly of Bi-Steel panels on site using an innovative ‘Slot and Lock’ connection technique.

Surefast enables highly secure buildings, to house personnel, or for the storage of data, equipment and materials, to be erected in just a few hours compared with days or weeks for conventional concrete structures.  The system involves using a unique connection technique to quickly join together the Bi-Steel panels as they are being erected on site. This eliminates the need for welding and instead utilises a Corus-designed bolted technology that is fast, highly effective and requires no specialist sub-contractor skills.  When the panels are erected they are filled with ready mixed concrete to create a highly robust structure that offers unrivalled protection against blast.

Benefits

• Protection – unrivalled security and blast protection
• Strength – exceptional strength for both operational and extreme loading
• Speed – buildings can be erected in days not weeks/months
• Quality – off-site manufactured accuracy

Surefast buildings can be clad using proprietary cladding systems to provide a structure that is not only functional but is aesthetically attractive and can easily blend in with existing surroundings.
