The core advantage is made of 304 food-grade stainless steel, complying with FDA food contact safety standards. The sandblasted surface forms a uniform anti-slip texture, with an anti-slip rating of R14, which can effectively prevent slipping even in humid and oily environments. Compared with ordinary carbon steel covers, it will not rust or peel, and can pass more than 2000 hours of salt spray test, adapting to coastal high-salt fog areas. The smooth surface has no dead angles, and can be easily cleaned by high-pressure water gun, without residual stains or bacteria, meeting the hygiene and disinfection requirements of food processing plants and hospitals. The modular design supports rapid installation, and the bolt fixing method ensures structural stability, and the non-magnetic property avoids adsorbing metal debris to cause trench blockage.
The standard size is 800mm (length) × 400mm (width) × 20mm (thickness), with a customizable size ranging from 500mm to 1200mm in length and 300mm to 600mm in width. The load rating is 120kN/m², which can withstand the traffic of medium-sized vehicles and pedestrians. The surface sandblasting roughness is Ra6.3, ensuring anti-slip performance while facilitating cleaning. The open area is 28%-32%, balancing structural strength and drainage efficiency. The mounting hole diameter is 12mm, adapting to M10 fixing bolts, and the connection is stable and reliable. The working temperature range is -20℃ to 120℃, adapting to high-temperature cleaning and low-temperature environments.
It is suitable for drainage scenarios with high hygiene standards such as food processing plants, dairy processing plants, hospital operating rooms, seafood restaurants, coastal commercial plazas and water treatment plants. It can be used as a cover for underground drainage ditches, ensuring smooth drainage while facilitating daily cleaning and disinfection, complying with food contact safety and medical hygiene standards, and will not produce odors or bacteria accumulation.
