• Industrial facilities and technical spaces
• Electrical rooms, shafts, and service areas
• Courtyards, inner yards, and service surfaces
• Environments requiring high load capacity and modular design

Material: Aluminum, hot-dip galvanized steel, or stainless steel AISI 304/316

Dimensions: Customizable for each project. Some standard sizes are available for faster delivery.

Load Classes: A15, B125, C250, and D400 kN, tested according to EN 124

Opening Method: Manually opened from above using cover keys

Hinges for easy opening

Gas spring for smooth handling

Insulated cover with glass wool core for temperature-sensitive installations or reduced energy loss

Burglar & safety grilles

Fire department lock or triangular lock

The product is available in multiple configurations and can be customized for load classes from A15 to D400 according to EN 124.

Configurations for A15 and B125 are designed based on technical specifications.

Configurations for C250 and D400 have been verified through load testing with test loads up to 400 kN.

All load tests were conducted on covers measuring 1000 × 1000 mm.

The choice of configuration should be adapted to the required load class and dimensions.

Always read the installation instructions included with your order carefully before starting any installation work, as they may vary depending on design and optional features.

Installation must be carried out by qualified personnel and adapted to the specific project conditions.

• Mount on a concrete foundation or equivalent base.
• Placement should be planned with regard to fire compartment boundaries.
• Ensure proper access for maintenance and emergency situations.

Always follow the specific operating and maintenance instructions provided with your order. Instructions may vary between different models, materials, and optional features.

For optimal performance and longevity, the access cover should be maintained regularly.

• Check that there are no obstacles before opening.
• Clean at least once a year using water and a mild detergent.
• Avoid abrasive cleaning products.
• Keep the space between the cover and frame free of dirt and gravel.
• Lubricate hinges as needed.
• Gas springs should be exercised at least every two months.

What is a checker plate ground access cover?
A checker plate ground access cover is a hatch made from slip-resistant steel or aluminum plate, installed in the ground to provide access to underlying installations such as electrical, plumbing, ventilation, or technical spaces.

Where are checker plate covers used?
They are commonly used in squares, urban areas, courtyards, parking lots, and pedestrian pathways where discreet and safe access to installations is required.

Which load class should I choose?
The choice of load class depends on the installation location:

• C250 – Suitable for pedestrian areas and urban environments.
• D400 – Suitable for areas with vehicle traffic, such as roadways and industrial zones.

Can checker plate covers be customized for stone paving?
Yes, they can be adapted for cobblestone, granite, or other stone surfaces to blend seamlessly with the surroundings. See our Cubic cover for examples.

Are checker plate covers safe in public spaces?
Yes, they are designed to be stable, slip-resistant, and compliant with standards such as EN 124 or FACTA.

Can a checker plate cover be used for smoke and heat ventilation?
Some covers can be modified with opening mechanisms or cutouts for integration with smoke and heat evacuation solutions.

What materials are best for checker plate covers?
Common materials include steel and aluminum, selected based on durability, weight, corrosion resistance, and intended use.

How is a checker plate cover installed?
The cover is installed in a prepared opening and either cast or mounted into the ground according to the manufacturer’s instructions.
