Platform ladders are specialized ladders designed to provide a stable and secure working surface at height. They typically feature a large platform at the top, allowing users to stand safely while performing tasks such as painting, maintenance, or construction. The design often includes guardrails for added safety and can be made from materials like aluminum or fiberglass. These ladders come in various sizes and configurations, making them suitable for both indoor and outdoor use. Some models are portable and lightweight, while others are more robust for heavy-duty applications. Proper use of platform ladders can help prevent falls and injuries in the workplace.
