Please get in touch with us if your required size is not listed

 Our spiral duct is made to the DW144 specification, but we can make your spiral duct out of a different gauge if requested. Please bear in mind that any spiral duct purchased at a different gauge will no longer conform to DW144 BESA Standards.

The table shows the weight of each diameter of spiral duct as a 3m length. The weight is based on the spiral duct being manufactured to the DW144 standards; custom gauges or lengths will not match this table. Please note these weights will not be 100% accurate.
