The Luzhongbao 1200\u00d7740\u00d760 Ductile Iron Split-Type Square Grate is a professional solution tailored for such demanding applications. Cast from high-strength QT500-7 ductile iron in strict compliance with national standards like GB\/T 23858, it is specifically designed to meet heavy-duty (Class D400 and above) or ultra-heavy-duty (Class E600) load requirements. Its unique \"split-type\" structure (two-piece design) significantly reduces the weight of a single cover plate, greatly facilitating daily opening, inspection, and maintenance operations. It is the ideal safeguard for the safe and efficient operation of large square inspection
