ZEROplus has introduced a range of fire and smoke tested self-adhesive silicone fin seals, to complement its popular teardrop seals, 188S, 488S and 388S. The 1771S (single fin) and 1772S (twin fin) have been developed specifically as meeting stile seals in response to requests from steel door manufacturers to solve the problem of sealing meeting stiles on pairs of fire rated doors. With Tee fins at 90 degrees, both can be fitted to either the astragal or the leading edge on a pair of doors. The 1773S (available soon) and 1777S have Tee fins at 75 degrees and can be used as perimeter seals fitting into the rebate across the head and down both sides of the frame. All four seals have been positively assessed for use on insulated or uninsulated fire rated steel doors, for a duration up to 240 minutes to BS EN 1634-1. This new range has also recently been included in a series of smoke leakage tests and achieved the requirements of BS EN 1634-3. Copies of all reports are available upon request. They are all supplied with double sided backed PSA (pressure sensitive adhesive) tape and are suitable for internal and external doors. These products are currently only available in black, although they may be available in dark bronze, white and grey depending on quantity. Please contact us for more information.

With many of our products being fitted to both the external and internal faces of outward opening doors, we are often asked for information regarding a products resistance to the elements, and in particular, corrosion. Test data relating to corrosion resistance may already be available for some of the specialist door hardware we distribute, especially the CE marked items, but for a lot of products it’s not. Although not an essential characteristic for most items, we at Zero like to have the answer! Therefore, across a wide range of products, we have carried out some independent Corrosion Resistance testing to BS EN 1670:2007 at a UKAS accredited laboratory. BS EN 1670:2007 specifies the requirements for the corrosion resistance of building hardware for doors, windows, shutters and curtain walling. It provides a method of classification of corrosion resistance of building hardware based on its performance in a neutral salt spray test. BS EN 1670:2007 is the standard used for corrosion resistance testing in many harmonised European door hardware standards such as BS EN 1125 and BS EN 12209 for instance. Briefly, testing involves placing products in a chamber ready to be sprayed with a salt water solution for a set number of hours. We decided to test for Grade 4 corrosion resistance, which is a 240 hour duration test, and classified as Very High Corrosion Resistance. We opted for Grade 4 as it is rarely tested to for door hardware with Grade 3 (96 hours) seeming to be the norm. We are pleased to advise that the following products were successfully tested to Grade 4; Outside Access Devices for panic & emergency exit hardware, surface mounted Door Stays, Door Stops, Lever Handles, Escutcheons, Pull Handles, Cylinder Pulls, Door Viewers, Gate Fittings, Vision Frames both square and circular, Door Louvres, Door Loops both surface mounted and concealed, Flush Bolts, Thresholds, Automatic Door Bottoms, Frame Seals, Rain Deflectors, Brush Strips, Door Selectors and Finger Protection. We believe having such a broad scope of products tested to Grade 4 will enable them to be specified and used with confidence in general external situations. Please contact us for details on exact products tested, and equally a full test report is available on request.
In recently undertaken independent laboratory Anti-Slip testing, our Modular Thresholds, 6.4mm Low Flat Thresholds and Traction Tread™ Thresholds achieved a ‘low risk’ classification to BS 7976-2. We are pleased to report that every Zero threshold tested received a 'low risk' (lowest possible) classification (36+ PTV) in dry conditions, with the majority of those thresholds tested also receiving this classification in wet conditions. Test evidence in regards to the slip rating of thresholds is regularly asked for in public transport applications. Testing covered Zero’s wide range of Modular Thresholds, 6.4mm Low Flat Thresholds and their Traction Tread™ Thresholds which have various infill’s to aid grip. A copy of the test report is available upon request.

Zero is pleased to announce it is now stocking Secustrip anti-jemmy strips. “We are very excited about the Secustrip product. It features two interlocking steel profiles which are fitted to the outside of the door and the side of the door frame, and fit together when the door is closed, protecting the gap between the door and frame against intrusion” said Sales Director Mark Lockley. “They are ingeniously designed to make forced entry by jemmy, crowbar or screw driver more difficult at the leading edge of the door where the lock is fitted.” This proven product is available from Stafford stock in two designs; Type 2 for inward opening doors and Type 3 for outward opening doors. They can be cut to size on site to suit the door height. The strips are made from zinc plated mild steel and are epoxy powder coated white (RAL9010) or brown (RAL8014). They can be used on new build or retrofit projects and are ideal for use on doors where security has already been compromised and a damaged door edge needs to be concealed. For further information please contact us.

Zero has also undergone successful independent testing to their Z003R concealed manual flush bolt to performance standard BS EN 12051:1999. Zero had noticed BS EN 12051 being called for more often in specifications in recent times, so thought it was time that their flag ship flush bolt is tested to this standard. Testing to BS EN 12051 covers important performance characteristics such as cycles, usage, corrosion resistance and security. After successful testing by Exova Warringtonfire the Z003R received a full classification of 3 3 - 0 1 3 2 to BS EN 12051:1999. The Z003R is manufactured to ANSI standards (American National Standards Institute) which means fixing positions do not vary and they can be fitted to pre-prepped metal doors. It has a 265mm adjustable rod and is supplied as standard in a satin chrome finish. The Z003R has also been included in a successful 4 hour fire test to BS476-22:1987.

Zero Seal Systems Ltd have just had their full range automatic dropseals positively assessed by UL International (UK) for use on previously tested steel based door assemblies to EN 1634-1:2014. When fitted with one of the Zero dropseals mentioned below, steel door assemblies would be expected to achieve a fire resistance performance of up to 180 minutes integrity. This new assessment covers the whole range, namely 320A, 321AA, 323A, 350A, 351AA, 352AA, 354A, 355A, 360A, 361AA, 364A, 364FSA, 365AA, 365FSAA, 367AA, 368AA and 369A. These models include patterns which are light, medium and heavy duty and also patterns which can be morticed, semi-morticed and surface mounted. Most Zero dropseals (or automatic threshold seals) are adjustable to 25mm. They work on a hinge-side plunger with a flat spring mechanism, so there are no electrics to deal with. The system drops a neoprene gasket in a scissor-like motion to form a tight seal with no drag – even on an uneven floor. The seal retracts automatically when the door opens. Sales Director Mark Lockley believes this just further strengthens Zero’s position as a market leading door hardware supplier “One of the major benefits of a steel door is the increased fire resistance they offer over say a timber door, well now Zero dropseals can be specified with confidence for fire resisting steel door assemblies. Having our whole range assessed for a duration of three hours to EN1634.1 is, we believe, ahead of the competition”. For further information please contact us.

Zero has undertaken successful fire testing on timber doors with the FLDL fusible link louvre in conjunction with an intumescent aperture liner. This intumescent has been specifically formulated for use with this louvre on timber fire doors and protects the door from burning through; it is not required on steel fire doors. The AL134PSA liner is 44mm wide and has been included in a successful 30 minute fire test on a 44mm thick timber door, while AL218PSA is 54mm wide and has been included in a successful 60 minute fire test on a 54mm thick timber door, both to BS EN 1634-1: 2008. BM TRADA Report CHILT/RF13260 refers, copy of test report available on request. The FLDL has been used on steel fire doors for many years, but it can now be used on timber fire doors. It is a self-attaching steel louvre (i.e. no holes need to be drilled in the door) with concealed fixings one side. In normal operation the blades can be opened and shut manually by means of a finger pull. In the event of fire, it has a fusible link which parts at 74⁰C and allows the stainless steel mechanism to snap the louvre blades shut, thus preventing the spread of flames. The standard finish is galvanised steel grey primed ready for powder coating but it is also available Grades 304 and 316 stainless steel. Expandable models are available to suit different door thicknesses. Please contact us if you require any further information on these products.
