Planning Roof Truss Deliveries

You would think that having a sizeable fleet of tractor units and truss trailers at your disposal would make the task of planning a week’s deliveries fairly easy but as we offer near nationwide coverage, any time spent in the yard is precious travelling time lost.   With that in mind, it is important that planning roof truss deliveries for each branch is a major focus.

new-trailer-2All orders and site call offs are kept centralised at our head office in Wellingborough to ensure that all information is readily available so queries can be dealt with as quickly as possible and also eliminate the possibility of duplicated or lost call offs between branches.  Michelle in our Production department contacts all site customers a full week before the trusses are due on site to ensure that build programmes are still on schedule before any deliveries are planned.  This takes some of the pressure site agents are under away to remove the risk of an unexpected delivery or forgotten call off.  Once all of the workload for the coming week has been confirmed, I designate each delivery to either Wellingborough, Essex and soon Abercarn.

As with most supply chains in today’s world, many of the sites we service want to keep their stock levels to the minimum possible.  What this means for us is that we may be delivering only half a load to a site at a time so wherever possible we will plan these deliveries to run alongside another site in the area.

When planning roof truss deliveries, we need to consider many different variables to ensure that what we plan to be possible on one trailer can be achieved.

  • Truss thickness.  We manufacture trusses in two widths, 35mm and 46mm.  A standard domestic roof will generally be in 35mm while a room in the roof design will be 46mm. Working on the width of our trailers, we can fit 72no. 35mm trusses or 48no. 46mm trusses.
  • Span of the trusses.  Our Essex factory could, if required, make a truss that was 40m long. Obviously, the challenges in getting that delivered to a site would be fairly large but the span of trusses must be taken into consideration on each plot as it usually has further implications.  For example, some roof designs will have small trusses supported on glulam beams with loose rafters down to a wallplate.  Looking solely at the small trusses (of which we could fit hundreds of on the trailer) could mean that the large timber packs which consume a lot of room on the trailer would be forgotten!
  • Height of the Trusses.  Along with the span of the trusses, we must consider the heights of the trusses.  Our trailers can accommodate trusses up to 4100mm high, but this would limit the possibility of having any material underneath them, thereby reducing the available space on the trailer.

Planning roof truss deliveries is a key success factor for our business, both in terms of cost and customer service. So as you would expect, we measure our success with regular surveys of the site managers we deliver to, and in turn we set ourselves targets based on ever improving service levels.
