• Infrastructure projects and urban areas
• Culverts, shafts, and technical tunnels
• Industrial facilities and logistics areas
• Public and commercial properties

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

Cover Options: Available as single cover, channel cover, or full cover set

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

Load Classes:

• SEFAC FL: A15 kN
• SEFAC FM: B125 kN
• SEFAC FH: C250 kN
  Tested according to EN 124, based on a test size of 900 × 900 mm

Opening Method: Manually opened from above using cover keys

Smoke & Heat Ventilation: SEFAC can be opened to allow ventilation and smoke extraction, and can be fitted with cutouts (SMS) for integration with smoke evacuation solutions

Cutout for fire hydrant key according to SMS 1188.

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

Anti-theft and security grille for enhanced safety.

The cover can be prepared for cladding with flooring materials, ceramic tiles, asphalt, or other surface finishes.

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.
• The frame is cast both from below and above to ensure a secure and durable anchoring.

Always follow the specific operating and maintenance instructions provided with your order. Instructions may vary depending on model, material, and optional features.

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

• Before operating the unit, ensure there are no obstacles in the cover’s movement path.
• The cover should be opened and cleaned at least once a year. Use clean water and a mild detergent with a soft cloth or sponge. Avoid abrasive cleaning products.
• Ensure the space between the cover and the frame is free of gravel and dust.

What is a ground access cover?
A ground access cover is an access hatch installed in the ground to provide safe access to underlying installations such as electrical, plumbing, ventilation, or technical spaces.

Where are ground access covers used?
They are 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:

• A15 – For pedestrian-only areas, such as green spaces, courtyards, and terraces.
• B125 – For pedestrian areas and light traffic, such as sidewalks, pedestrian streets, and parking areas for cars.
• C250 – For urban areas with occasional vehicle traffic, such as streets, squares, and parking zones.
• D400 – For heavy traffic areas, such as roadways, industrial sites, and logistics areas.

Can ground access covers be customized for stone paving?
Yes, they can be adapted for cobblestone, granite, and other types of stone paving to blend seamlessly with the surroundings.

Are ground access covers safe in public spaces?
Yes, they are designed to be stable, slip-resistant, and compliant with relevant standards such as EN 124.

Can a ground access cover be used for smoke and heat ventilation?
Some ground access covers can be adapted for smoke and heat ventilation solutions, for example through opening mechanisms or special cutouts.

What materials are best for a ground access cover?
Common materials include steel and aluminum. The choice depends on durability, weight, corrosion resistance, and intended use.

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