Rail Lift
Elevator guide rails are manufactured from low-carbon steel grade Q235B or KP80 per GB/T 700 and JIS A 5505 standards. The standard profile is an inverted T-shape with dimensional accuracy of ±0.3 mm and angular tolerance of ±0.5 degrees. Rail lengths are 5 meters connectable up to 20 meters with linear weight of 10 to 45 kg per meter. Surface hardness is maintained at 130–170 Brinell HB for wear resistance and deformation prevention. Maximum permissible deviation over 5 meters is 1.2 mm with local curvature below 0.3 mm per meter. These rails undergo stress-relief heat treatment at 550°C to prevent deformation from residual stresses.
The running surface for guide shoes is cold-drawn to a surface quality of Ra 2 microns with edge radii of 2.5 mm. Rail joints use 12 mm steel plates with four to six Grade 10.9 bolts tightened to 400 Nm torque. Hot-dip galvanized coating 75 microns or 65-micron catalytic epoxy coating is provided for high-humidity environments. Bending moment capacity ranges from 15 to 70 kN·m with torsional resistance up to 900 Nm per meter. Rails are designed to withstand dynamic loads up to 200% of rated load and vertical speeds up to 12 m/s. Production complies with EN 81-20/50, ISO 7465, and GOST 51616 standards for safety and durability assurance.

Rail Lift
Elevator guide rails are manufactured from low-carbon steel grade Q235B or A36 per ASTM A36/EN 10025 standards. The rail profile is an inverted T-shape with dimensional accuracy of ±0.3 mm and standard lengths of 5 meters. Linear weight ranges from 8 to 25 kg/m with flange thickness varying from 5 to 12 mm. Surface hardness is maintained at 130–170 Brinell HB for enhanced wear resistance. Maximum permissible deviation over 5 meters is 1 mm with angular tolerance of ±0.5 degrees. These rails undergo thermal normalization for uniform crystalline structure and internal stress reduction.
The contact surface with car guide shoes is cold-rolled to a surface roughness of Ra 1.6 microns. Rail joints use steel couplers and four Grade 10.9 bolts with tightening torque of 300–500 Nm. Hot-dip galvanized coating minimum 80 microns or epoxy powder coating 60 microns provides corrosion protection. Bending capacity ranges from 250 to 900 MPa with ultimate tensile strength of 370–500 MPa. Rails are designed to withstand dynamic loads up to 200% of rated load and vertical accelerations up to 2.5 m/s². Production complies with EN 81-20/50, ISO 7465, and GB/T 10054 standards for safety and flawless performance.

Rail Lift
Elevator guide rails are manufactured from low-carbon steel grade KP80 or KP100 per JIS A 5505 standard. The standard profile is an inverted T-shape with dimensional accuracy of ±0.5 mm. Rail lengths are 5 meters connectable up to 10 meters with linear weight of 8 to 30 kg per meter. Surface hardness is maintained at 120–160 Brinell HB for wear and deformation resistance. Maximum permissible deviation over 5 meters is 1.5 mm with local curvature below 0.5 mm per meter. These rails undergo stress-relieving heat treatment for dimensional stability in temperatures from –40°C to +150°C.
The guide shoe contact surface is mechanically finished to a surface roughness of Ra 3.2 microns. Rail joints use 12 mm steel plates with 4 to 6 Grade 8.8 bolts tightened to 300 Nm torque. Hot-dip galvanized coating 85 microns or catalytic epoxy coating is applied for humid environments. Bending resistance capacity ranges from 200 to 800 N/mm² depending on profile design. Rails are designed to withstand dynamic loads up to 150% of rated car and counterweight loads. Production complies with EN 81-20/50, ISO 7465, and GOST 51616 standards for safety and durability.
