Material and surface protection:

• Row steel (ST 37-2 / S235 JRG)
• Aluminium ( Al 99,5 i AlMg 3)
• Stainless steel (AISI 304-316)

       Surface protection:

• Row without surface protection.
• With surface protection by hot dipped galvanizing according to DIN 50 976.
• Painted.

Dimension of mesh:

• Applies to all models of stair-steps.

Models of stair steps:

• Stair step * model RSP
• Stair step * model RS
• Spiral stairs * model SRS1
• Spiral stairs * model SRS2

Fixing for existing construction:

• Screws M12 – attached with 4 screws for each stair step
• Welding for existing construction

Drawing stair steps - model RSP

Drawing stair steps - model RS :

Note:

• Stepping edge-anti slip profile, there is the possibility of making steps without this profile.
• The side plates with holes are produced for fixing .We can produce stair steps without side plates for fixation.

• Example: RSP-Tzn-2x30-33x33-800x1000mm
  
• Model: RSP or RS
  
• Surface protection: hot dipped galvanizing (Tzn)
  
• Bearing rods dimensions (thickness x width): 2x30mm
  
• Mesh size : 33x33mm
  
• Length (span) x Width: 800x1000mm
  
• 
  Additional explanation:
  Length (span):  The size of grating in direction of bearing rod. It is placed first in the description of grating size.
  Width: The size of grating in the direction of connecting rod.

Most common size of stair steps – model RSP and RP :

• Bearing rod: 2x30 / * on request 3x30mm 2x25 / 2x40 / 3x25 / 3x40mm
• Length (L): 600 / 800 / 1000 / 1200mm * or upon request.
• Width (W): 240 / 270 / 305mm * or upon request.
• All dimensions are subject to change, and compliance with the requirements of the project and customer.

Tolerances for the dimensions of stair steps:

• L = MAX   +0  /- 3mm
• W=max.   +5 /- 5mm
• For other dimensions see pdf catalog stair steps - tolerance of dimensions.

SPIRAL STAIR STEPS:

Spiral stair steps are produced in two models:

• Spiral stairs * model SRS1
• Spiral stairs * model SRS2

Drawing - spiral stair step:

Note:

• Most common length (D): 600 / 800 / 1000 / 1200mm * or upon request.
• All dimensions are subject to change, and compliance with the requirements of the project and customer.
