Ductile Iron Covers & Frames
Gatic sets the standard for access covers and frames, offering a combination of matchless quality with tried and tested solutions. The secret lies in the closely machined horizontal and vertical seating faces of the cover and frame components, which, when assembled into a complete unit, provide a cover and frame that is non-rocking, gas- and airtight. Available in solid top or recessed design as a single, duct or multispan configuration, Gatic Ductile Iron Covers & Frames provide durable, high-performance solutions for demanding environments. Rated up to F900, they suit highways, airports and industrial sites, and are configurable for various underground services. Solid tops offer slip resistant strength without infill, while recessed covers enable seamless aesthetic integration with surrounding surfaces.

Ductile Iron Access Covers, including both Solid Top and Recessed designs, are high-performance solutions engineered for durability, stability, and long-term reliability in demanding environments. Manufactured from robust ductile iron, they meet stringent industry standards and load classifications up to F900, making them suitable for heavy-duty applications such as highways, airports, ports, and industrial sites.
These covers are available in a variety of configurations, including single covers, duct covers, and multispan, allowing access to a wide range of underground services, from small chambers to large, continuous utility trenches.
Solid Top Covers feature a raised lozenge pattern surface that provides a tough, slip-resistant finish without the need for concrete infill, resulting in a lighter yet exceptionally strong solution.
Recessed Covers are designed to be infilled with surrounding surface materials, enabling them to blend seamlessly into paved or landscaped environments for a clean, architectural appearance.
Both types incorporate precision machined horizontal and vertical seating faces, ensuring a non-rocking fit and forming a gas-, air- and watertight seal. This prevents movement under traffic loads and protects underground
infrastructure from water and debris ingress.
Suitable for applications such as manholes, utility ducts, service trenches, and access chambers, these covers deliver high structural integrity, vandal resistance, ease of access, and visual consistency, making them ideal for commercial, infrastructure, and public realm projects.
