Treatment process regarding finishes on Stainless steel products are outlined in Sydney Water July 2015 update.  The default finish is now bead blasting:  “2.3 Surface Finish – Unless otherwise specified, painting of stainless steel vents is not required. All external stainless steel surfaces shall be bead blasted to achieve a non-directional low reflective uniform matt finish  with a surface roughness profile of Ra 3.5 to 4.5 microns. Blast media shall be glass. The blasting media shall be free of contamination including iron and steel.” Coating to WSA 201 Standard using Pur-B system is available where specified.

There are 3 types of vent shaft cowling available: wire cowl (non-directional, also known as a bird cage); rotating cowl (also known as a whirly bird, used in educt cowls); and forced induct cowl (has a tail like appendage). We manufacture, supply and install.
