Mild Steel Square Box (SHS) Hot Dip Galvanised


Some Local Governments (Councils) require steel storm-water conduits or drainpipes to traverse pathways or other council property.  Rectangular or Square Steel Hollow Sections or Square/ Rectangular Steel Tube is specified for stormwater drainage pipes across the council footpath from the owners property to the kerb or gutter.  


Most common council specifications will call for Steel pipe – minimum wall thickness 4mm.  Hence we stock our  100 x 100 x 4 SHS in Hot Dip Galvanised finish, ideal for these applications and in longer lengths (some branches) to help with longer runs and diagonal crossings.

Common Applications

Stormwater Drainage pipe   

Structural - Columns and Frames

Mechanical - frames and assemblies

General Engineering

Trailers and Truck bodies


Edcon Steel Tips

Consider cutting the drain pipe first from plain SHS and then sending the item to the Galvanizer after your SHS piece is cut to size.

Stock holdings will vary branch to branch, so be sure to contact your nearest branch before heading in to pick up this item.

Treatment of cut ends should be considered as the cutting process will break the galvanising protection of the steel.

Refer to the local government in your area for requirement specific to your site.
