Square steel pipe

Square steel pipe

Square steel pipe

Our selection of square steel pipe can be easily shaped and formed, welded by all common methods, and has high load-bearing capacity as well as stability.

During production, the steel is rolled into a square shape, bent and welded, and then galvanized.

The material belongs to the material group "unalloyed structural steels" and is one of the most widely used structural steel grades in metalworking. The material is, of course, suitable for magnetization.

Thanks to galvanization, these square pipes can withstand even the most adverse weather conditions - especially moisture - for a long time.

Galvanized square 4-sided pipes are suitable for many indoor and outdoor applications - such as:

  • Railings
  • Garden gates
  • Frame racks for furniture
  • in mechanical engineering
  • in construction engineering

To protect square pipes from corrosion, our square pipes are galvanized inside and out, and the cut edges are treated with zinc spray.

Where are galvanized steel rectangular pipes used?

Whether in your own home, apartment or neighbor's garden, our galvanized steel rectangular pipes are used in many commercial sectors. Galvanized rectangular steel is very stable due to its geometry and is therefore suitable as a modern & versatile structural element for numerous professional as well as hobbyist applications in the outdoor and indoor areas - for example:

  • for stands and exhibition stands
  • for balustrades on balconies, terraces and stairs
  • for the skeleton construction of tables, shelves, benches and other furniture ● in the construction of machinery and equipment

Galvanized steel as a material

Steel is an alloy that consists mainly of iron. It is very resilient and can be machined in many ways, such as:

● forging and welding

● cold and hot forming

● machining

annealing and hardening

● rolling, drawing and bending

Galvanized steel is often used in plant construction. Due to the myriad types of steel, there are almost no restrictions on particular areas of application. Thanks to galvanization, our steel no longer needs to undergo surface treatment. Needless to say

However, surface refinement processes such as wet painting, powder coating or even the electroplating process are also possible.
