Under general working conditions, boom lifts made of steel are more durable; however, in corrosion-resistant and light-load long-term use scenarios, aluminum alloy performs better in terms of durability.
Your concern about how long the equipment will last is indeed a crucial question. The "durability" of the two materials manifests in different dimensions:
Steel: Possesses higher absolute strength and impact resistance, capable of withstanding frequent heavy loads, complex stress cycles, and harsh outdoor environments (such as wind, sun, and low-temperature impacts). The structure is less prone to deformation, and key connection parts are reinforced for extended lifespan. It is particularly suitable for high-intensity tasks such as municipal emergency repairs and high-altitude power line operations. However, despite the anti-rust coating, long-term exposure to humid or salt spray environments may still lead to corrosion, requiring regular maintenance.
Aluminum Alloy: Although its strength is relatively lower, it is naturally corrosion-resistant and oxidation-resistant, and will not rust, making it particularly suitable for high-humidity, coastal, or chemically corrosive environments. Its lightweight design also reduces the burden on mechanical components (such as hydraulic systems and wheel sets), indirectly extending the service life of the entire machine. In indoor or light-load, high-frequency use scenarios, aluminum alloy lifts can often achieve "maintenance-free, long-cycle operation".
