Steel square pipes

The heavy-duty profile for the highest (dynamic) loads.


A strong basis.

Our 45 x 45 mm steel square pipe is made of galvanised steel and has a very high load-bearing capacity, even under dynamic loads. This makes the steel square profile ideal for building constructions that is exposed to the rigours of everyday logistics (e.g. the use of forklift trucks).

Due to its enormous stability, the steel square pipe is particularly well suited for the construction of base frames for tugger trailers and chassis frames.

The square steel system forms a particularly stable basis for the realisation of
customised solutions for industrial use.


Easy to combine with the other BeeWaTec pipe racking systems (round pipe steel, round pipe aluminium and aluminium square pipes) via MC and MC4 joints.


Lean solutions can be easily modified and adapted should your circumstances or requirements change.

Steel square pipes (45x45 mm)

Our steel square pipes 45x45 mm have a wall thickness of 3 mm, are galvanised and have a very high stability.

Steel square pipes can be combined with MC joints (45x45 mm) as well as with MC4 joints (45x45 mm). This allows you to realise your solution flexibly and quickly.

Square pipe joints steel (45x45 mm)

To obtain stable and efficient pipe constructions from individual pipes, we offer a system of square steel pipe joints in 45x45 mm. The joints are ideal for trolleys and other wheeled systems when a stable base frame is needed.

These joints can be used for our steel square pipes (45x45 mm) as well as for our aluminium square pipes (45x45 mm) and secure the pipes reliably with screw joints.

The steel square pipe joints (45x45 mm) come in two versions:

MC steel joint connects two square tubes with one round tube across corner

MC steel joints (45x45 mm)

MC steel joints connect square pipes (45x45 mm) with round pipe profiles (28x28 mm) and are preferably used as corners for transport trolleys.

MC4 steel joint connects three steel and/or aluminum square pipes together

MC4 steel joint (45x45 mm)

MC4 steel joints (45x45 mm) connect square pipes (45x45 mm) made of steel
and/or aluminium with each other and are used for heavy-duty solutions (Example: shelves and transport trolleys).
