3″4″ Roof Drain Grating R1300 Series Asme A112.6.4

The R1300 Series Roof Drain Grating (Model LWDG1001) is engineered for high-performance drainage applications, specifically designed to meet the rigorous standards of ASME A112.6.4. Crafted from high-grade ductile iron (ISO1083/JS/500-7), this product offers exceptional durability, load-bearing capacity, and resistance to environmental stress, making it an essential component for commercial, industrial, and municipal roofing drainage systems.

Overview and Design Excellence

Effective roof drainage is critical to maintaining structural integrity and preventing water accumulation-related damages. The LWDG1001 series is meticulously designed to optimize water flow while preventing the ingress of debris, leaves, and other obstructive materials that could compromise the drainage system. Its robust construction ensures long-term operational reliability in diverse weather conditions, ranging from heavy precipitation to intense solar exposure.
