Protect your spiral duct installation from dust and debris
Our dust protective film is a cost effective solution to prevent the ingress of dust and debris into your installation.
Large orders
We manufacture our own spiral duct and can fulfil large orders. We hold a large stock at our three branches, however during busy periods sometimes demand overtakes supply. Should you wish to make a large order (100 lengths or above) please contact us for lead times.
Deliveries
We can offer deliveries through out the Southeast and London on our own fleet of 10 vans. For orders that are a bit further out we can quote competitive carriage charges (we only pass carriage charges on from our network of couriers). Carriage charges will depend on the size of the order and these charges will be clearly itemised on our quotation. We endeavour to keep these charges at a minimum as much as possible.
