Access Manhole Cover Frame

For marine and industrial tank applications, our Access manhole cover frame provides a foundation of impenetrable strength. We use marine-grade carbon steel (Q235B) or 316L stainless steel to manufacture these frames, ensuring they can withstand the constant corrosive spray of seawater and the pressure of ballast tanks. Every Access manhole cover frame is forged or welded using our 27,000sqm workshop's heavy-duty equipment, followed by precision leveling (flatness ≤0.05mm) to ensure a perfect, airtight seal when bolted to the deck or tank.

We recognize that on a ship or in a fuel storage facility, an unreliable seal is a disaster. That is why our Access manhole cover frame is designed to meet strict shipbuilding standards, handling pressures up to 0.6MPa. We apply a multi-stage marine-grade anti-corrosion coating to every frame, ensuring it survives the swaying, vibration, and impact of long-range voyages. Whether you require a standard oval shape or a custom circular design, our factory provides the same high-quality supplier standards that earned us the trust of Sany Heavy Industry.
