Transportation Applications
High-weather-resistance, lightweight coated aluminum coils—preferred base material for rail transit and marine applications
Coated Aluminum Coils｜Lightweight Material Solutions for Transportation
Lidao’s extra-wide coated aluminum coils are core aluminum base materials custom-developed for the high-end transportation equipment sector.
Made from carefully selected premium primary aluminum, and built on intelligent extra-wide production lines with a mature, stable coil-coating process, they combine lightweight construction, high corrosion resistance, strong weather ability, easy formability, and the elimination of secondary spraying. With stable, reliable quality, they suit the full range of applications—rail transit, commercial vehicles, and transportation support equipment—making them a preferred material for transportation equipment manufacturers worldwide.
Typical Applications — Lidao Extra-Wide Coated Aluminum Coils
-
Rail Transit Applications
Suited to high-speed rail and metro manufacturing, the extra-wide sheet reduces splice welds and improves the vehicle body’s integrity and flatness.
Used for interior and exterior wall panels, roofs, partitions, doors, and interior trim panels, the product resists vibration and wear, is low-smoke and non-toxic, and can sustain the high-intensity operating conditions of rail vehicles over the long term.
-
Commercial Vehicle Applications
Compatible with new-energy buses, special engineering vehicles, box trucks, and similar models. The lightweight material effectively reduces weight and saves energy while extending driving range;
the dedicated coating resists salt spray, aging, and erosion, delivers strong outdoor durability, and keeps a clean surface without later repainting—greatly lowering vehicle operation and maintenance costs. -
Freight Cars and Reefer Vehicles
Exclusively supplying extra-wide coated aluminum coils for car bodies, with thickness from 0.005–3.0 mm and a maximum width up to 2700 mm, suited to interior and exterior retrofitting of containers and freight cars; the high-strength coated coils are wear- and corrosion-resistant and widely used for the fabrication and refurbishment of box-truck shells.
Our self-developed fluorine-free coated aluminum coils can be laminated with fluorine-free insulation materials to form refrigerated-truck insulation compartments—eco-friendly, odorless, with excellent thermal performance, meeting cold-chain constant-temperature transport needs.
We also supply multi-specification embossed aluminum plates for car bodies (pointer, diamond, and five-bar patterns), using A1100 and A3003 alloys, thickness 2.0–6.5 mm, standard widths 1.0 m and 1.22 m, with excellent anti-slip and load-bearing performance, suited to car-body retrofitting and in-vehicle anti-slip flooring.
-
Transportation Support Equipment
Suited to scenarios such as transportation fuel tanks, on-vehicle insulation housings, and station-supporting panels.
The product resists corrosion and weathering and adapts to complex environments including coastal, high-humidity, and open-air conditions. The base material is highly ductile and supports bending, stamping, and other shaped processing, yielding high finished-product stability.
Core Advantages
