Quick answer: LED screen cabinets are mainly made of die-cast aluminum (light and precise, ideal for rental and fine-pitch indoor LED displays), sheet steel (low cost and strong, common for fixed outdoor LED screens) or magnesium alloy / carbon fiber (ultra-light, premium).

FAQ
Which cabinet material is best for an LED display?
Die-cast aluminum is the best all-round choice for flatness, heat dissipation and weight. Steel is more economical for large fixed outdoor LED screens.
Why are rental LED screens made of die-cast aluminum?
Rental LED screens are assembled and moved often, so light, precise die-cast aluminum cabinets speed up installation and keep seams tight.
How much does an LED screen cabinet weigh?
A 500×500 mm die-cast aluminum cabinet typically weighs 6–8 kg, while a steel outdoor cabinet of 960×960 mm can weigh 35–50 kg.
