A comparison of the GEZE roller carriages: Rollan 40, Rollan 80 & Perlan 140 sliding door gear

When specifying sliding door gear for timber doors, one always needs to know the weight of the doors.  Illustrated in the photo above can be seen the difference in the axle construction between the 3 main GEZE systems; the Rollan 40, the Rollan 80 and the Perlan 140.  The weight limit per door in kgs is the 40, 80 and 140 of the systems’ names.  The Rollans both share the same aluminium track profile, which comes in a mill finish (i.e. not finished).  The Perlan 140 has its own chunkier and more heavy duty track, which is finished in an attractive satin anodised aluminium.  Double doors can be accommodated on the same track by simply buying an extra door pack.

Perlan 140 dimensions

GEZE Perlan sliding door gear for timber doors weighing up to 140kgs.
The heavy duty satin anodised aluminium track comes in various lengths and can easily be cut down. Nylon rollers with low friction nylon wheels and roller bearing axles give superior running performance. The sliding door kit comes complete with track, runners, door brackets, side mounting brackets and stops.  The floor guide is concealed – fixed to the floor next to the door frame, it runs in a groove in the door leaving the threshold free from obstructions.

“Heavy Duty” is not a subjective term – how to be sure you’re buying quality door handles

The term “Heavy Duty” is no longer subjective, there are EN standards which define the use and durability of each product. A suite of European product performance standards (ENs) have been developed for most building components, these include a comprehensive range of product performance standards for architectural hardware. Products are ‘marked’ with a six or more digit classification coding which shows in detail just what levels of product performance are being claimed for the item. This classification system enables complementary items to also be specified to, for instance, a common level of corrosion resistance, category of use, door mass, etc. as shown below.en-numbers

The important numbers defining the durability of a door closer for example are the first, second, forth and sixth digits. These are as follows:
Digit 1 – Category of use
Grade 2 – for use by people with some incentive to exercise care but where there is some chance of misuse
Grade 3 – high frequency of use by public or others with little incentive to exercise care and with a high chance of misuse.
Digit 2 – Number of test cycles
Grade H – 200,000 cycles; 10N (load on latchbolt)
Grade X – 200,000 cycles; 120N (load on latchbolt)
Digit 4 – Fire Behaviour – Suitability for use on fire/smoke door assemblies having successfully completed a fire test to EN 1634
Grade 0 – not approved for fire/smoke doors
Grade 1 – suitable for use on fire/smoke doors subject to assessment

Digit 6 – Corrosion Resistance – Level of corrosion resistance to EN 1670 Neutral Salt Spray test and operation of the product at extreme temperatures
Grade F – high corrosion resistance; -20°C to +80°C
Grade G – very high resistance; -20°C to +80°C
Marking – To order to comply with the EN standard each product and/or its packaging are required to be marked with:  
The manufacturer’s name or trademark or other means of identification.
Product identification number.
The six or more digit classification number as above.
The BS EN standard number e.g. BS EN 1154 for door closers
The year and week of manufacture (this may be coded).
CE Marking – To be marked with the European Commission’s CE mark, a product will hold all the required certification including classification code of product, type-testing to EN number, manufacturer’s mark, year of manufacture, EC certificate of conformity etc. which will be verified by the notified certification body.

I need a door closer that is able to close a steel door which is 400kg in weight. The door size is w1000mm x h2050mm.

February 1, 2012 by · Comments Off on I need a door closer that is able to close a steel door which is 400kg in weight. The door size is w1000mm x h2050mm. 

We recommend looking at a Geze TS4000 tandem (power 7-13), or a TS4000 power 5-7, and caution that this door will be very heavy to open.  You can buy them online here, follow the links in the text.

I need to put a digital lock on a door, but can I have a different code on either side of the door?

October 24, 2010 by · Comments Off on I need to put a digital lock on a door, but can I have a different code on either side of the door? 

Yes.  The medium duty Lockey L2430 double sided digital lock will do that job.  The heavy duty Lockey L1150DS double sided also offers this feature.  The code can be the same on each side, or different.

We would recommend either the Geze TS5000 guide rail door closer, or the Geze TS4000 standard arm door closer, both are adjustable power size 1 – 6, with a range of excellent features and suitable for very high usage, heavy duty doors.  They are stock items you can buy here.
