We recently had a request for a repeat order for a bar rail chair suitable for ½” x 1” hot rolled steel rail. The last order had been placed in 2005 for an installation in Canada where they do not have access to metric bar rail.
But this re-order came with a rather unusual question: At a track-planning meeting yesterday the question of low-temperature tolerance of your chair material in a Canadian winter was raised. Can you tell me what the usable temperature range is for the chairs please? In our location the extreme low temperature would be about -20C on rare occasions. A normal winter low would be in the -5C to -10C range.
We had to put in quite a bit of research on this alongside the suppliers of the polymer. Although the manufacturers did not specify a minimum usable temperature in their data, we had been given a verbal assurance previously that it would withstand the temperature range requested.
Reassuringly for users of our metric sized chairs, these are also made from the same weather resilient polymer.
So, as we speak, 800 of these chairs are en-route to Canada. We will endeavour to find out how they faired in the depths of a Canadian winter.
The imperial chair is shown below alongside PNR-12K metric bar rail chair and below that in situ in Canada.
We are considering putting the imperial measurement chair into full production and adding to our website as a stock item. Do you think that it would be an item that would be of interest? Please do let us know.
