Manhole cover 800x800 mm 792.080.080

Manhole – a solid solution for professionals and users

The 800x800 mm manhole is a reliable infrastructure element, used to access underground installations, wells, canals and other facilities requiring regular inspection or maintenance. Made of high-quality stainless steel, it provides durability and corrosion resistance, making it an ideal choice for both commercial and private use.

Construction and materials

A key element of this manhole is its construction based on stainless steel 1.4301 (AISI 304). This grade of steel is characterized by high resistance to weathering and corrosion, guaranteeing long-term use even in harsh environmental conditions. The steel thickness is usually 3.5 mm, which provides adequate rigidity and strength of the structure. Additionally, the manhole is equipped with hinges and a lock with a key – also made of stainless steel – which increases security and prevents unauthorized access.

It is worth mentioning the possibility of filling the manhole with concrete, which increases its resistance to loads. If it is necessary to reduce the weight of the manhole, expanded clay concrete can be used. Internal reinforcement with rods further strengthens the structure. An EPDM gasket ensures the manhole is waterproof and gas-tight.

Applications and benefits

This model of manhole is widely used in:

• Urban infrastructure: sewer manholes, culverts, water and gas connections.
• Industrial construction: access to underground technological installations, tanks, pipelines.
• Residential construction: access to septic tanks, sewage pumping stations, heating installations.
• Gardening: access to irrigation systems, lighting installations.

Why choose this manhole?

• Durability and resistance: Made of stainless steel, it ensures long-term use without the risk of corrosion.
• Security: A stainless steel lock with a key protects against unauthorized access.
• Waterproof: The EPDM gasket guarantees a tight connection, protecting against water and gas leakage.
• Load resistance: The possibility of filling with concrete increases resistance to external loads (load classes A15, B125, C250 available depending on the manhole height).
• Easy installation: The set includes anchors for mounting the manhole frame.
• Availability of various sizes: A wide range of sizes (from 200x200 mm to 1000x1000 mm) allows you to adapt the manhole to individual needs.

Additional optional equipment includes a security grate, a drainage inlet and lifters to facilitate manhole operation. It is also possible to make a manhole from steel 1.4301 (AISI316) or other noble materials to order.
