Elevator guide rails are manufactured from fine-grained non-alloy carbon steel per DIN EN 10025-2. The common grade is S355JR with a minimum yield strength of 355 MPa. Rail surfaces undergo a hardening process to achieve a hardness of 149 to 197 Brinell. The dimensional tolerance of the T-type profile, according to EN 81-20, is maintained within ±0.25 mm. The standard length per rail section is 5 meters, with production possible up to 8 meters. Rails are joined using steel fishplates and hot-dip galvanized grade 8.8 bolts. The total vertical alignment accuracy in the hoistway must not exceed 10 mm per 30 meters.

The rail profile is designed as a broad-based T-shape. This shape provides maximum bending resistance and stability against lateral forces. The contact surface for the guide shoes is finished to a surface roughness Ra below 3.2 µm. This reduces the coefficient of friction and enables silent travel. Rails are protected against corrosion by zinc flake coating or hot-dip galvanization. The protective coating thickness varies between 45 and 85 microns. The rails temperature tolerance is defined for -20 to +120 °C without deformation. Their fire resistance complies with class A1 DIN 4102.

An elevator guide rail is a hardened steel component that provides the path for the cabin and counterweight in an elevator system. Rail length is designed according to building height, ranging from 3 to 100 meters. Standard cross-section dimensions are 50×50 to 60×60 mm, with steel plate thickness of 8–12 mm. Rails are made of stainless steel or wear-resistant steel to ensure over 20 years of service life and minimal mechanical wear. Standard installation spacing is 1.0–1.2 meters, with alignment accuracy of ±1 mm to ensure smooth cabin and counterweight movement.

Rails are mounted to walls or steel frames using bolts and anchors and are in direct contact with cabin rollers or bearings. Contact surfaces are chrome-plated or wear-resistant to reduce friction and ensure smooth, quiet operation. Rails must be installed perfectly vertical and aligned to prevent vibration, noise, and wear. These rails are optimized for residential elevators up to 15 floors and commercial elevators up to 25 floors.
