Product Description
304 Stainless Steel Outdoor Drain For Tunnel Cover
Product Overview

304 stainless steel outdoor drain cover customized for tunnel engineering is a professional water drainage and anti-blocking accessory designed for tunnel exterior and entrance drainage systems. Manufactured with high-purity 304 stainless steel material, this drain cover features excellent natural corrosion resistance and stable mechanical toughness, adapting to long-term humid, dusty and alternately wet-dry working environments at tunnel openings.

The optimized uniform mesh structure balances high drainage efficiency and effective debris isolation, which quickly discharges accumulated rainwater and surface runoff while blocking fallen leaves, sediment and roadside garbage from entering tunnel drainage pipelines, effectively preventing pipeline blockage and tunnel waterlogging risks.
