Composite sewer manhole / technical access cover | hatch | Ø900mm | C250 | SMC | black

The cover is classified as C250 according to EN124. Covers of this class are used in areas adjacent to carriageways, kerbside areas, kerb and drainage zones, parking areas and other locations where vehicle loads may occur but where the D400 class is not required.

SMC composite is non-metallic and has electrically insulating properties. The material also helps reduce the accumulation of static electrical charge and the risk of electrostatic discharge.

C250 class is suitable for kerbside areas, zones adjacent to carriageways, kerb and drainage areas, parking spaces and other locations exposed to similar loads.

If the cover is installed in the main carriageway where heavy vehicles travel directly and continuously, it must be assessed whether the project requires a higher load class.

The rubber sealing ring and side sealing structure are designed to reduce the penetration of water, gases, odours, oil or other liquids between the cover and frame.

The -60°C...+150°C range describes the temperature resistance of the SMC material used in moulded products. Operating conditions for the complete structure also depend on sealing elements, fixing and the installation location.

• C250 load class suitable for moderate vehicle loads.
• EN124 standard defines the cover load class.
• Ø900mm opening provides a large access area.
• SMC composite construction is corrosion-resistant and does not rust.
• Resistance to fuels, oils and chemicals makes it suitable for industrial and traffic areas.
• Sealing system helps protect the manhole from ingress of water, liquids and odours.
• Lockable bolts help protect the cover against unwanted opening.
• Raised anti-slip surface improves grip.
• Electrically insulating material does not have the electrical conductivity typical of metal structures.
• Lower weight than cast-iron structures may simplify transportation, installation and maintenance.

• Correctly prepared base required: C250 performance also depends on correct installation of the frame.
• Large external dimensions: the frame diameter is approximately 1020mm, so sufficient installation space is required.
• Not intended for all high-traffic carriageway areas: a higher load class may be required in such locations.

A technical manhole is installed in a car park or kerbside area. A large Ø900mm access opening, resistance to vehicle loads and resistance to a corrosive environment are required. The C250 composite cover is installed into a properly prepared base. The rubber sealing ring helps reduce the ingress of water and other liquids, while the lockable bolts prevent the cover from being easily opened without tools.

C250 according to EN124.

C250 is used in kerbside, kerb, drainage, parking and other areas where vehicle loads may occur but where the higher D400 class is not required.

If the project requires D400 or a higher load class at the installation location, a C250 cover is not suitable for that area. The load class must be selected according to the specific installation zone.

The opening diameter is Ø900mm.

The outer frame dimension F is 1020mm.

The overall construction height is 100mm.

SMC composite material.

The SMC composite structure does not rust like steel or cast iron and is therefore suitable for corrosive environments.

Yes. The SMC material is resistant to petrol, diesel fuel, lubricants and many chemicals.

The construction uses lockable bolts operated with a hex key.

Yes. The cover surface has a raised anti-slip structure.

The C250 load class is determined not only by the cover itself but also by the correctly installed frame and supporting base. The installation structure must reliably transfer vehicle loads to the surrounding base. Before installation, the opening, frame and installation dimensions must be checked, and it must be confirmed that the C250 load class meets the requirements of the specific installation zone.
