Custom outdoor cast iron drain covers
Our custom outdoor cast iron drain covers are engineered for municipal infrastructure, landscaping, and utility access applications where durability, load performance, and surface safety are critical. Each cover features a studded anti-slip surface pattern, integrated lift slots, and a precision-fit recessed frame for flush installation in pedestrian and road surfaces. Available in EN124 load classes from A15 to D400, with fully customizable diameter, surface pattern, logo casting, and frame depth. OEM and ODM orders supported with sample production available before mass order commitment.
*Provide your application requirements—such as stress conditions, materials, size range, and even product name. We are always available for customization, so please contact us directly.
Introduction
Why Choose Our Outdoor Cast Iron Drain Covers?
Anti-Slip Studded Surface Pattern — The raised stud surface provides reliable slip resistance for pedestrians in wet outdoor conditions, meeting safety requirements for public footpaths, car parks, and plaza installations.
Precision-Fit Recessed Frame — The matching cast iron frame is machined for a snug, rattle-free fit, preventing noise under foot and vehicle traffic while maintaining flush alignment with the surrounding pavement surface.
EN124 Load Class A15 to D400 — From light pedestrian walkways to fully trafficked carriageways, our drain covers are manufactured to your specified load class with the rating cast directly into the cover surface for permanent identification.
Custom Logo & Text Casting — Municipal authority names, utility company logos, and custom text panels can be cast directly into the cover surface during production, a standard requirement for water, gas, and telecoms utility access covers.
Anti-Theft Locking Option — Bolt-down and hinge-lock variants available to prevent cover theft and unauthorized access, increasingly specified in urban municipal and utility infrastructure projects.
Corrosion-Resistant Bitumen Coating — Standard black bitumen finish provides long-term corrosion protection for outdoor below-grade installation, with epoxy coating available for aggressive soil and coastal environments.
