Specification Summary:
Bolton Gate Company’s range of 60 minute rated, A0 fire shutters have been specifically developed to provide a compact and highly effective solution for the closure of numerous types of opening in fire rated bulkheads.
Tested to the latest IMO Resolutions and in accordance with the 2010 FTP Code, the Fireroll A0 has been approved and certified by most of the leading marine authorities including RINA, USCG, Lloyds, DNV & ABS.
Exported around world, the shutters are manufactured at our factory in the UK in accordance with the Company’s ISO 9001:2015 Quality System. Accordingly, we are also authorised to use the wheelmark standard alongside our MED approval and Module D Certification.
In keeping with SOLAS II-2, the Bolton Gate A0 rated shutter is often used (in conjunction with a third-party sprinkler system) as an entirely legitimate and more cost effective alternative when there is a requirement for an A60 door or rating on a servery type opening.
The Fireroll A0 has been supplied on countless marine projects around the world. Primarily used on internal and external servery type applications, the A0 fire shutter has also been installed in front of catering equipment, pizza ovens, walkways, shop or concession entrances, lift doors, stairwell atriums, ‘toy cupboards’, ROV and lifeboat hangars.
The list of vessels using the A0 shutter to provide fire safety is extensive, ranging from cruise ships, super yachts, ferries and riverboats to naval aircraft carriers, destroyers, frigates, submarines and patrol boats. The fire shutter is also utilised on container ships, reefer vessels, tankers and carrier ships, PSV’s, Support vessels, drill ships, offshore platforms and wind turbine laying and cable laying vessels.
The shutter is operated manually, simply by pulling the curtain down or pushing the curtain up.
Due to a sprung barrel the curtain will remain at any point between fully open and fully closed positions if required.
Self-closing in a fire condition is achieved by activation of a fusible link when the local temperature exceeds 68°C. An alternative method of closing is provided by a 24v DC magnet allowing connection to the fire system – this also includes a timer delay and sounder beacon to give notice of the impending shutter closure.
Locking can be provided in the form an espagnolette with or without keyed access from one or both sides.
Shutter curtains are constructed from continuously interlocking 51mm flat section galvanised steel laths which are securely held in place by steel endlocks.
The bottom rail is also formed from a reinforced lath to give uniformity of appearance.
A stainless steel nameplate is fitted stating the relevant approval body and the unique door reference for traceability purposes.
The shutter curtain runs in vertical guides fabricated from cold rolled galvanised steel channels each with continuous steel angles. These angles are pre punched to ensure fixing to the bulkhead at the correct centres.
The roller is made from a seamless steel tube of adequate diameter and wall thickness to avoid deflection and its solid steel shaft is supported in bearings mounted on each endplate. A counterbalance spring is fitted within the roller and fine adjustment of tension is achieved by a ratchet and pawl mechanism fitted to the outside of one endplate.
Fabricated from steel plate and prepared to accept the coil casing. Securely bolted to steel angles which are drilled for attachment to the bulkhead at the correct centres.
The coil casing is constructed from galvanised steel and attached to the structure by setscrews.
The shutter is supplied in a white polyester powder coat finish (RAL 9010) as standard.
2900mm clear width x 2100mm clear height.
Varies with opening size dependent on lath/barrel/casing requirements but approximately 50kgs/m².
