GI Square Pipe
GI Square Pipe is galvanised iron pipe with a square cross-section. Its flat faces make it easy to join, drill and fix things to, which is why it is used for frames, doors, gutter supports, gates and any part of a structure that needs clean, square joints. The galvanised coating keeps rust away in wet, humid farm conditions. It is available in 20 mm to 90 mm OD, in 2 mm and 3 mm thickness.
Key Features
Square cross-section: flat faces for neat joints, bolting and welding.
Galvanised finish: zinc-coated to resist rust and corrosion.
Seven sizes: 20, 33, 42, 48, 60, 76 and 90 mm OD.
2 mm and 3 mm thickness: lighter or heavier section to suit the load.
Benefits of GI Square Pipe
Stiff and stable: resists bending and twisting in frames and doors.
Easy fabrication: cuts square, sits flush and takes fasteners easily.
Clean finished look: gives doors, gates and frames a tidy, professional finish.
Long life outdoors: galvanising protects it through seasons of weather.
Where It Is Used
Polyhouse doors and entry frames: including double-door entry rooms.
Gutter and curtain supports: where brackets need a flat surface.
Nethouse frames and gates: square framing for nurseries and shade structures.
Sheds, stands and benches: general farm and nursery fabrication.
The size and thickness to use depend on the load, span and design of the part being built.
