High Speed doors

1) Is a High Speed door the same as a roller door?

A High Speed door provides fast access between rooms, zones or departments. High speed doors are particularly suitable for high traffic areas, as the fast opening speed provides optimal conditions for smooth and secure logistics.

2) What are the advantages of a High Speed door?

High Speed doors are space-saving compared to, for example, sliding doors. They require minimal overhead and side space, making it possible to place them in most locations. They are an economically attractive choice for several reasons:

  1. they require virtually no maintenance
  2. they are extremely reliable
  3. they have a very long life
  4. They are quickly and easily repaired in case of collisions

High Speed doors are available in models suitable for chill and freeze up to 160 mm thick. 

3) Would you recommend a High Speed door for cold room or freezer?

High Speed doors is an advantage wherever there is a lot of traffic.

At DAN-doors we have High Speed doors with different degrees of insulation performance, and our product range can be tailored to all needs.

We have High Speed doors with 2-4 mm insulation, which is used in combination with a night sliding door, and we have insulated doors with 100-160 mm insulation, which have such good insulation performance that they are fully competitive with both traditional sliding doors on insulation and with lighter High Speed doors on speed.

4) Can the High Speed ports have different opening speeds and opening times?

There are savings to be made by optimising both open and close speeds for each port.

The automation for our High Speed doors is flexible and can be adapted to open and close at the speed that makes sense for you. It also means you can choose to have different opening and closing speeds, depending on the needs of your different zones.

5) Is it possible to choose different operating options for High Speed doors?

You can choose from several automatic control options. As standard, the High Speed doors are supplied with two pressure panels, but you can also choose from some of our other solutions, such as pull cord, radar, remote control, photocells and much more.

6) Can you produce High Speed doors to special measurements?

All the High Speed doors we send out are made to measure, and we have supplied everything from small doors for passageways to very large doors for large logistics halls.

7) Can I have my own print on the door leaf?

You can get a personalised and customised print on the doormat of almost all our High Speed doors, except AVR100.

Doors for security and industry

1) What is a industrial door?

A industrial door can have different purposes and there is therefore no single answer to the question. At DAN-doors we supply both industrial doors as hinged doors and as High Speed doors for industrial purposes.

2) What is a security door?

Our standard industrial doors can be produced as RC3, which ensures that we as manufacturer and supplier meet the strictest requirements within the European standard EN-1627. This also means that the doors meet the burglary classification RC3 according to EN-1627.

The classification means that both the door and the frame must be able to withstand a simulated burglary based on certain assumptions, including that the construction must be able to withstand a normal burglary attempt lasting less than 20 minutes. The five minutes of the test are considered as active execution with tools, and the remaining time is assumed to correspond to rest, changeover and the planning expected to perform the burglary.

3) Can we choose the colour of our industrial door?

All DAN-doors' products can be produced and painted in the colours our customers want. The doors can be painted in 60 my for indoor use and 120 and 150 my for outdoor use. For environments where there is a heavier load on the doors, they will also be painted with 120 and 150 my.

4) is an industrial door the same as a High Speed door

At DAN-doors we supply various industrial doors.

High Speed doors is a flexible door solution that can meet a wide range of industrial needs, as it is space-saving, energy-efficient and user-friendly.

Our sliding doors are another attractive industrial door solution, and finally, hinged doors can be a good solution for both chill, freeze and fire.

All our products can be delivered with automation and customised with individual RAL colours.

Fire doors

1) What is a fire door?

A fire door prevents the spread of flames and toxic smoke in the event of a fire, allowing evacuation, and can therefore have a crucial impact on safety. That's why we set high standards for our fire doors at DAN-doors.

Fire doors and fire curtains must be approved and certified according to a wide range of very strict requirements, including materials. They can be certified in different classes, which indicate whether the door is approved for escape routes or for partitioning between fire zones.

2) E, EW and EI - What do the abbreviations mean?

E stands for integrity, which covers the resistance of the fire door or fire curtain to fire for the given number of minutes.

W stands for radiation, which covers the protective capacity of the fire door or fire curtain against heat radiation for the given number of minutes.

I stands for insulation, which covers the fire door's or fire curtain's insulation capacity against fire for the given number of minutes.

Ranked, EI-certified solutions provide the absolute highest fire safety, as they are approved to provide the greatest protection at a very small distance from the fire door or curtain. This means that EI-certified fire solutions are approved to secure escape routes.
Next come EW-certified solutions, which protect against heat radiation at a slightly greater distance from the fire door or curtain, and finally E, which simply prevents the fire from spreading but does not provide any protection for people or property.

3) 30, 60 AND 120 - What do the numbers mean?

The fire classes E, EW and EI will always be followed by digits indicating how many minutes the fire curtain or fire door provides protection against flames, radiation and close passage respectively.

4) Can you explain the transition to the current European standards for fire doors?

In the past, the abbreviations "BS" and "BD" were used, which simply stood for "fireproof" and "fireproof". BS indicated that the door was made of a non-combustible material, while BD indicated that the door could be made of combustible materials, which nevertheless had a high resistance to fire.

On 1 November 2019, the BS60 certification, which until then had been the Danish certification for fire doors, expired. This means that since 1 November 2019, BS60 doors no longer have to be used as fire doors in facades. However, BS60 doors may still be used in the interior of buildings if the doors are used for passenger traffic. All fire doors placed in facades must now be CE marked to be approved for use under European legislation.

The fact that the fire door is CE marked means that the product complies with European legislation, and the European certification is your guarantee that all countries now work to the same certification for fire doors.

All DAN-doors' EI fire doors for facades are CE marked to comply with the new standards for fire doors. Our fire doors are produced according to customer requirements and are approved as long as they stay within the maximum and minimum dimensions of the certificates.

If you want a CE marking of your fire doors, they must be tested according to standard EN1634-1 requesting the CE marking. For smoke doors, they must be tested to standard EN1634-3. In addition to this, your FPC must be approved by an accredited company.

5) What is the difference between BD and BS marking compared to CE marking?

The overall difference between the two certifications (BD and BS classifications versus CE marking) is that BS doors are tested from one side only, whereas EI doors are tested from both sides of the door. The European classified fire doors can always be offered in tenders where BD or BS doors are defined. However, this is not the case the other way round: if European classifications are defined, these are the ones that must be followed.

6) Can I get a fire door for the cold room or freezer?

DAN-doors supplies fire-resistant hinged and sliding doors for chill and freeze. The doors are supplied with fire batts in the door leaf, as well as fire-retardant sealing strips. Fire-retardant means that the sliding door requires approval by the local fire authority, which is usually achieved without any problems.

Fire doors for coolers and freezers can therefore be designed as both hinged doors and sliding doors. However, it is important to note that freezer doors are not normally approved as fire doors. Approval requires the local fire authority to approve the door, which is usually done without any problems. Please feel free to contact us if you would like to know more about the benefits of choosing a fire door for chill and freeze.

7) What are the advantages of choosing a fire door for chill and freeze?

You kill two birds with one stone.

In supermarkets, warehouses and other places with refrigerated environments, it is first and foremost essential to choose a door with a high insulating effect. The wrong temperature can quickly lead to damaged frozen or refrigerated products or increased energy bills, with considerable financial losses.

For most businesses, however, security is equally important, and many of our customers therefore want to combine the insulating effect of a cold room door with the security of a fire door.

It can be done. We manufacture fire doors with high insulation performance, which are simultaneously insulated with fire batts and 15 mm fireboard. So you kill two birds with one stone and get insulation and safety in one door.

8) What are the benefits of a fire door?

In larger food processing plants, where doors are opened and closed many times a day, a sliding door ensures minimal litter loss. Sliding doors also save space, and where fire separation is required, a fire door is the best choice. 

Greater security:

Safety is of course the main advantage of choosing a fire door. A solid fire door can be the difference between life and death in the event of a fire.


Fire can have disastrous financial consequences. Fire doors prevent the spread of fire to other areas of the building and you gain time to extinguish the fire. In this way, damage to property, interiors and important documents is minimised, and there can be significant savings from investing in a fire door.

Customer-specific solutions

Of course, you will get the fire door that suits your needs. In addition to protecting against smoke and flames, the doors can be customised according to specific wishes for size, colour, shape and function.
