18kg rail is a widely used light steel rail with a theoretical weight of 18.06 kg/m, designed to GB/T 11264-2012. It is commonly used in underground mines, factory workshops, trolley tracks, small cart systems, and temporary construction lines. Manufactured from hot-rolled Q235 or 55Q carbon steel, this rail features a simple profile and a stable base that balance load capacity with flexibility. It supports low-speed transport and handling systems with axle loads up to 5 tons. Standard lengths range from 6 m to 10 m, with custom lengths available. Easy installation and low maintenance make 18kg rail a cost-effective choice for fast-deployment projects. With ample stock on hand, we support both quick delivery for small orders and reliable supply for large-scale projects.
The following table details the cross-sectional dimensions of the 18kg rail as specified in GB/T 11264-2012. Accurate control of head width, web thickness, and base width ensures stable tracking, reduced wear, and safe operation under low-speed, light-load conditions.

18kg rail is lightweight enough for standard lifting tools and small cranes. It allows faster positioning and alignment, reducing installation time on site.
Compared with heavier rail, 18kg rail lowers material, transport, and installation expenses. It suits projects that prioritize cost efficiency in light-duty applications.
Standard lengths and jointed connections simplify maintenance. Crews can replace sections efficiently without long downtime.
We maintain active stock of 18kg rail in our dedicated warehouse, ready for prompt dispatch. Customers can access a consistent supply without waiting for mill production.
All rails come in standard 6 m lengths. Rails are stored on raised pallets to prevent moisture and deformation, ensuring they arrive in top condition.
We offer flexible shipping options, including FOB, CIF, and EXW, to suit different project and delivery requirements.Flexible supply arrangements help meet both small orders and larger project requirements.
Glory Steel Work has years of experience exporting 18kg rail worldwide. Rails are carefully bundled, secured, and stored to prevent moisture and deformation during transit.
Standard 6 m rails fit into 20-foot containers, while 8 m and 10 m rails require 40-foot containers. We handle both small and bulk shipments, supporting FOB, CIF, and EXW terms to match customer requirements.
