Template drilled hinges originated because of the need for absolute accuracy of the fixing holes in metal doors and frames.This allows for doors and frames to be pre-prepared because hinges produced by different manufacturers will have the drillings in exactly the same positions.For template pattern

Intumescent materials other than edge strips are used on fire resisting doors. For example, thin sheet material can provide insulation and protection: ◆ behind hinge blades ◆ around mortise lockcases ◆ around concealed door closers Intumescent pads can protect hinge positions.

What is spring hinge? Single action spring hinge:A spring hinge has a spring in its “knuckle”, which is larger than usual. The spring is linked to one flap at the top and the other flap at the bottom. Therefore, when the door opens, the spring is wound up, as the two flaps rotate apart. When the do

Self-closing door hinges are usually designed to ensure that the door can slowly close on its own after being opened. Although these hinges are relatively inconspicuous, they can actually be found in many large facilities, such as schools, shops, and hospitals. In some crises, such as fires, earthqu

Door hardware includes knobs or handles and all latching and locking mechanisms. This is technically called a lock set whether or not the hardware contains a lock. Different lock-sets are designed for different applications. Once you have determined the decision on the type of lock set required for

This European standard applies to cylinders for such locks as are normally used in buildings and are designed to be used with cylinders. It identifies one category of use grade, three grades of durability, three grades of fire resistance, four grades of corrosion and temperature resistance, six grades of key security, and five grades of attack resistance.

Some items of building hardware are essential to ensure that the fire-resisting door stays closed in its frame in a fire emergency.

BS EN 12209 classifies mechanically operated locks, latches and locking plates using an 11 digit coding system. This has proved necessary in order to provide a proper assessment of all the varied features of products for specific markets within Europe. It should be noted that to avoid a greater proliferation of boxes, certain features have been “doubled up”: e.g. durability and durability with side load; door mass and closing force; corrosion resistance and temperature resistance. The system is comprehensive but it has led to the use of letters (rather than numbers) in certain boxes, since there can only be one digit in each classification box. A similar classification system applies to all building hardware product standards (at least for the first 7 boxes) to aid meaningful comparisons with related products.

This standard provides details on product types, classification by use, test cycles, door mass, corrosion
resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the published standard includes annexes with details for special applications.
