How to assemble modular stairs?

Linea straight stairs are assembled according to the manual instructions. Assembly is based on bolted connections. When assembling Linea modular stairs, remember about a properly level concrete base, which will ensure safety of use.

Linea stair platforms can be assembled in two ways:

  • With support posts
  • With supports anchored to the wall


Assembly of the modular stair platform is possible in 6 variants:

  • A platform with a straight descent
  • A platform with a descent to the left side with supports
  • A platform with a descent to the right side, with supports
  • A platform with a descent to the left side with posts
  • A platform with a descent to the right side with posts
  • Without a platform

In addition, both external and internal stairs have an adjustable inclination angle of 33 °, 37 ° or 40 °. The Linea system is targeted at the industrial sector, therefore we offer two types of step filling:

  • Profiled grating
  • Welded grating

They have been created in accordance with the standards of the TLC company. They have a non-slip function, thanks to which they increase the safety of use. The system is equipped with a light industrial railing. For straight stairs, we have provided two options for assembly of an additional handrail: Handrail assmebled on the wall (instead of a railing) Internal handrail (additionally assembled to the railing to increase the comfort of use)

Linea modular stairs are a simple solution for industry. Check the available dimensions of our steel stairs here or contact us! We will help you select the right parameters so that the implementation goes even faster. Choose comfort and safety of use.


The table below presents height and length of the stairs depending on the number of steps, angle and landing variant

  1. Choose the type of stairs from page 4 (P, BP, LS, LW, PS, PW ).
  2. Estimate the height of stairs you need, and then find the approximate value in the column “H”.
  3. Check the value in the column “L” that corresponds to the value from column “H” that you have chosen before. The “L” value is the length of the flight of stairs – check if it fits your area.
