While RHS (Rectangular Hollow Section) is a versatile structural profile, it is also widely used—and often mandated by councils—as a high-durability stormwater pipe solution. At Vincent Buda & Company, we supply hot-dipped galvanised RHS used to direct stormwater from residential and commercial properties to the street.
RHS is preferred by plumbers and civil contractors because it provides a low-profile, high-strength alternative to round PVC pipes, particularly where clearance is limited under driveways and footpaths. We offer a wide range of profiles and lengths to suit virtually any application, along with a full range of accessories to ensure every RHS installation is straightforward and efficient.
Every length is hot-dipped galvanised to withstand constant water exposure and soil contact without corrosion, meeting the demands of Australian plumbing and drainage standards. When RHS is required by the council, there is no substitute—RHS is the only compliant solution.
Primary Applications for RHS:
Stormwater Kerb Outlets: The final steel section that discharges house water into the street gutter.
Footpath Crossings: A low-profile alternative to round pipes that can be encased in shallow concrete walkways.

FREQUENTLY ASKED QUESTIONS
RHS steel is used primarily for its structural strength, especially under driveways and footpaths where vehicles regularly pass over. Unlike PVC, steel can handle the weight of cars, trucks, and council vehicles without cracking or collapsing. This makes RHS the preferred—and often mandated—solution where drainage must withstand traffic loads while remaining low-profile.
Yes. Under driveways and footpaths, where vehicles regularly drive over and cover is limited, RHS steel is far superior to PVC. PVC can crack or deform under vehicle loads if it isn’t buried deep enough, while RHS steel provides the structural strength and crush resistance needed to handle cars, trucks, and council vehicles—even when installed closer to the surface.
Our RHS drainage steel is supplied with a hot-dipped galvanised finish. This is critical for plumbing applications as it provides both internal and external protection against corrosion from constant water contact and soil acidity, ensuring the longevity of the drainage line under concrete.
