What is an RHS section?

What is DuraGal?
DuraGal are cold formed hollow sections that are hot dip galvanised to AS/NZS 4792 and have a minimum average coating mass of 100 grams per square metre applied to the exterior of the section. DuraGal is made from hot rolled coil that is in-line galvanised.
What is the difference between SHS and RHS?
RHS is the most prevalent term and is generally accepted for describing square hollow section as well, which is technically incorrect. The correct term for square tube is SHS which stands for Square Hollow Section. Less known is the term CHS, this stands for Circular Hollow Section.

How is Shs measured?
The most direct and widely used method to measure ETS exposure is personal monitoring of respirable suspended particles and nicotine. Respirable suspended particles and nicotine give a good indication of cumulative exposure over a relatively short period of time.
How long does DuraGal last?
It is noted that the corrosion life for unpainted Duragal is the same for very severe tropical and moderate, that is it is suitable for long term use 10-15 years.
What is the difference between SupaGal and DuraGal?
SupaGal is very similar to DuraGal, except that the RHS sections are galvanized on both the external and internal surfaces. When the term hot-dipped galvanised is used, it is normally taken to mean that the hot-dipped galvanising happens after the chassis is constructed.
Is SHS or RHS stronger?
Obviously this depends on the relative size of the sections. Assuming that the rectangular section’s smallest dimension is equal to (or greater than) the square section’s side and their thicknesses are equal, then the rectangular section will always be stronger than the square, for any load in any orientation.
