safety in your hand

Burglars are under high time pressure, so that already 5 minutes of resistance time will make the attempts fail. Furthermore, 80% of the perpetrators are only occasional offenders. They do not take a high risk of detection and select objects with unsecured weak points. Prying open the shield or pulling protruding cylinders can be effectively fended off.

Secure the front door with protective fittings!

Every four minutes there is a burglary in Germany. The biggest weak point in flats: the flat entrance door.

Although around 75% of all burglaries target apartment buildings, too little attention has so far been paid to securing the flat entrance door with front door fittings. Burglars are under great time pressure. Attempts to resist for as little as five minutes fail. Moreover, 80 percent of the perpetrators are only occasional thieves. They do not take a high risk of detection and choose properties with unsecured weak points. Contrary to popular belief, 80 percent of burglaries take place during the day when the residents are out of the house - preferably between 10 am and 1 pm. Apartment buildings are particularly affected.

Prising open the shield of a front door security fitting or pulling protruding cylinders can be effectively warded off with a security fitting from Griffwerk.

Effective burglary protection for your home!

The number of domestic burglaries continues to rise in Germany. However, most attempts could be thwarted by the right burglary protection. Too little attention is paid to the protection of front doors in particular.

You should pay attention to this with your flat entrance door:

  1. Invisible screwing prevents screwing on/off from the outside.
  2. Special hardened steel plate offers resistance to drilling, knocking off and bending.
  3. 3. Hardened steel cylinder cover prevents the profile cylinder from being pulled out.

Resistance classes of protective fittings

For classification purposes, protective fittings are classified into resistance classes. They indicate how strong the burglary protection is. Depending on your individual protection needs, choose fittings from four different protection classes (ES0-ES3).

GRIFFWERK equipped the revised range of protective hardware with flanking sales support for specialist trade and crafts. GRIFFWERK has solutions at hand for sales exhibitions and mobile consulting as well.

Resistance class ES0

Components in the resistance class have basic protection against attempts to break in with physical force (mainly vandalism) such as kicking, counter-jumping, shoulder throwing, pushing up and tearing out.

✓ Suitable for secondary doors such as garage doors

Resistance class ES1

The casual burglar additionally tries to break open the locked and bolted component with simple tools such as screwdrivers, pliers and wedges.

✓ Suitable for flat entrance doors, front doors

Care instructions for stainless steel: Door handles, window handles and co.

High quality material with intelligent surface

GRIFFWERK does not limit itself to elegant design - we are proud of the inner values of our products. We only use stainless steel alloy 304, also known as "1.4301". Due to its composition, this high-quality steel - matt or polished - is rustproof with exceptional corrosion resistance and durability. Stainless steel forms a very thin protective passive layer, which rebuilds itself even after surface damage caused by chemical reactions.

Care spray for door handles

GRIFFWERK recommends using special stainless steel care sprays to care for and maintain the value of your stainless steel door handles and fittings. They clean intensively, have a dirt-repellent effect and thus maintain the value of your stainless steel door set, lever handles and door fittings. Please do not use any aggressive cleaning and scouring agents containing alcohol for cleaning - regardless of whether the stainless steel surface is matt, polished or shiny. Please note that the surface of the lever handle set can be damaged if it is exposed to unusual stresses, such as building dirt, sanding dust, aggressive vapors or salt water. Therefore, clean the lever handle set with a stainless steel care spray immediately after soiling.
