A good Intersteel door closer provides extra comfort, cost savings and makes your door last longer. With a closer, your doors are opened and closed in a controlled manner, which prevents damage to your door and the wall. In our store you will find a wide range of Intersteel Door Closers, including Intersteel Door Closers with a scissor arm and a sliding arm.

What is an Intersteel Door Closer?

You undoubtedly know them, Intersteel Door Closer. But why is it that these are so widely used? Intersteel door closers actually only have one function. That means letting the door close quietly. This ensures that both your door and the wall will not be damaged and will therefore last longer.

How the Intersteel Door Closer is installed depends on the situation in your home. The door closer can be mounted on the frame or on the door. The mechanism contains a spring and a shaft. This is attached to the door or frame. The closer is housed as a whole in a steel housing. In this way, the closer ensures that the door closes in a controlled and quiet manner.

Choose between a scissor arm or a sliding arm

We have two types of door closers in our range. These two are by far the most common. These are the closers with a sliding arm and with a scissor arm.

A scissor arm works with what is also called a rack, which is a gear on a rectangular bar with teeth. If you open a door with a scissor arm, the door hardly loses any force and the resistance usually remains the same.

A sliding arm works in a different way, here the closer revolves around a spindle in the shape of a heart. This creates a kind of decreasing torque, the door is then still easy to operate within an angle of approximately 30 degrees. A sliding arm usually offers the most beautiful appearance once the door is closed, because the arm to which the door is attached slides into the housing.

With a scissor arm, the arm extends clearly outwards when the door is closed, this is clearly visible. Because a sliding arm is a more advanced system, these Intersteel door closers are usually more expensive.

Optimal closing force

If you purchase an Intersteel Door Closer, you naturally want your door(s) to close smoothly, but what closing force is optimal for your doors? The closing force with which a door closes depends on several factors. This is determined by the spring pressure and the door width. Other factors that influence the closing force are the weight of the door, wind load, air pressure, seals and locks. All these factors influence the closing force. Many factors, such as closing speed, deceleration and acceleration, can be adjusted in the Intersteel Door Closer.

Advantages of an Intersteel Door Closer

An Intersteel door closer ensures that your doors close automatically, which has several advantages. This prevents damage to the door, the wall and the door fittings in the door. This is because the door does not swing open and hit the wall. Another advantage is that there are now no more open doors in your home or business premises, this ensures that rooms remain at the right temperature more easily and this in turn reduces heating costs. Automatically closing doors also have the advantage that small children or your pets do not move from one room to another.

Different denominators for the same intention

If you have already read up on the subject of Intersteel Door Closer, you may already know: there are many different denominators for the same product, the same method or the same technique. In this section we would like to tell you more about this, so that you are completely clear about what is meant by all the names.

The side where no hinges are visible is called the counter-hinge side, 'non-hinge side' or the reveal side. The terms 'frame sill mounting' and 'end mounting' are used for mounting.

Installing an Intersteel door closer

There are four different possible mounting methods to install an Intersteel Door Closer:

1. Frame sill mounting on hinge side
2. Door leaf mounting hinge side
3. Frame sill mounting reveal side
4. Door leaf mounting reveal side

The first method, the frame sill installation on the hinge side, is the most commonly used method for installing a closer. With this method, the closer is placed on the frame above the door. On the side of the door where the hinges are visible. The arm is attached to the door itself.

Can't the closer be placed on the frame because it is too narrow, for example? Then you can use the door leaf installation. With this method, the housing is placed on the door and only the arm needs to be mounted to the frame.

Finally, you should take the direction of your door into account. If the door opens inwards, the closer can be mounted on the hinge side of the door. If the door opens outwards, it is important that the closer is placed on the inside.

Adjust the Intersteel Door Closer properly for optimal convenience

It is important that the Intersteel Door Closer is properly adjusted for optimal convenience. We therefore discuss some important points below for properly setting a closer, for optimal convenience.

• Closing speed – First consider the speed at which the door can best close. You can then adjust this steplessly. Should the door fall into the latch? Then set a final stroke. With this stroke the door falls a little stronger at the end, so that the door falls nicely into the lap.
• Opening damping - Is it a door that is regularly thrown open forcefully, or flies open by the wind? Then set the opening damping. This ensures that the door is braked from approximately 70 degrees. After this angle, the door will open much more heavily, so the door never hits the wall.
• Closing delay - There is also a possibility of closing delay, which stops the door between 120 and 70 degrees, making the door less likely to fall back. This is the well-known effect that allows you to walk quietly through the door after opening the door.
• Locking device – Finally, special arms are available with a locking device. This is also called a ratchet locking arm. With this option you can easily open the door firmly, so that you can walk up and down a few times without having to open the door every time.

Fire resistant doors Intersteel Door closer required

Schools and hospitals, among others, are required to install fire-resistant doors. This is to ensure good fire safety in certain compartments of a room. This also applies to large office buildings, or think of a town hall.

For fire safety, there are special EN standards that prescribe when fire-resistant doors and moving parts of fire separation are mandatory.
