elevator rail , Iran

Elevator guide rails are manufactured from low-carbon steel grade KP80 per JIS G3101 with minimum yield strength of 360 MPa. The standard profile is an inverted T-shape with dimensional accuracy of ±0.2 mm and angular tolerance of ±0.3 degrees. Standard rail length is 5 meters seamlessly connectable up to 15 meters with linear weight of 12 to 40 kg per meter. Surface hardness is maintained at 140–170 Brinell HB for wear and deformation resistance. Maximum permissible deviation over 5 meters is 0.8 mm with local curvature below 0.3 mm per meter. These rails undergo controlled stress-relief heat treatment at 550°C to prevent installation warping.

The running surface for guide shoes is cold-drawn to a surface quality of Ra 1.2 microns with edge radii of 1.5 mm. Rail joints use 12 mm steel plates with four Grade 10.9 bolts tightened to 400 Nm torque. Hot-dip galvanized coating 80 microns or 70-micron electrostatic epoxy powder coating is applied for corrosive environments. Bending moment capacity ranges from 15 to 70 kN·m with torsional resistance up to 1000 Nm per meter. Rails are designed to withstand dynamic loads up to 200% of rated load and vertical speeds up to 12.5 m/s. Production complies with EN 81-20, ISO 7465, and GB/T 10054-2021 standards for safety and durability assurance.You can order and buy elevator rail from Iran by contacting us through whatsaap and email.
