Park Sewage System Slotted Cast Iron Drainage Trench Grate

A1: It is integrally cast from thick high-density cast iron with anti-rust matte coating. The material has excellent heat resistance, it will not deform, bend or crack under long-term open flame and high-temperature baking, perfectly fit for fire pits and barbecue stoves.

A2: The evenly spaced radial long slots have a large circulation area for water flow and heat circulation. It can block large branches and stones while keeping smooth drainage and air flow, and it is much less likely to clog compared with dense small-hole grates.

A3: Thanks to solid one-piece casting structure, it owns strong load-bearing and impact resistance. It can support daily pedestrian trampling, heavy cookware and outdoor equipment without breaking, suitable for public pavement and high-frequency use scenes.

A4: It has wide usage scenarios: outdoor fire pit covers, courtyard drainage manhole grates, barbecue stove support racks, catering kitchen furnace accessories, tree pool drain covers for landscape, workshop ventilation filter grates and park road drainage systems.

A5: The square uniform outline fits standard reserved openings directly without secondary cutting. The smooth rounded edges have no burrs; you only need to rinse ash, mud and sundries with water or wipe with a brush to finish daily cleaning.
