At IEP we're proud of the investments we have made in leading edge machinery and infrastructure. It gives us a competitive advantage as it means we can take on projects that are too large for many of our competitors, in terms of both the volume and size of the ductwork required.
This 2000x2000mm PPs 90 degree bend, with turning vanes, is typical of the ductwork projects we are involved in, and whilst many competitors would say that they could make this, few are of a scale that could make this and all the other components required for a complete ductwork system.
In-house fibreglass resource is also critical in many larger scale ductwork projects. Un-reinforced PVC fabrications are prone to damage if they are mis-handled, and transporting large components between fabricator and glasser leaves the item vulnerable to damage, which the main contractor might never be able to see once glassed and fitted. For that reason we recommend that contractors confirm that glassing capability is held in house.
One can only imagine the damage that could have been done had this large, flanged PVC ductwork transition section need to be transported to the GRP contractor in an un-reinforced state. Cracks in the PVC would have gone unnoticed, until some time after commissioning when the glass itself becomes the target of chemical attack from the fumes and condensate.
It's for these reasons that we always recommend to first time customers that they physically attend their fabricators' premises as part of their new supplier audit, to ensure that what is being said to them actually holds up to scrutiny.
