Secure hold for panel materials - the edging profile
An edging profile is a structural element used to hold a panel material securely along an edge. It relieves the semi-finished product mechanically by absorbing the static forces. This makes it possible to install large panels made of material with low breaking strength.
Production of a edging profile
Edging profiles are conventional profiles. They are long materials with a constant cross-sectional area. The design of the cross-sectional area also serves to increase the bending stability of edging profiles. In addition, edging profiles are shaped to offer a matching groove for panel materials with a defined width.
The production method of edging profiles depends on the material used. There are two production methods to choose from:
In the extrusion process, primary-formed block material is pressed through a die at high temperatures. The material melts in the die and takes on its shape. Behind the die, a water jet cools the freshly formed edging profile again. The material solidifies and retains its shape. The extrusion process is suitable for all thermoplastic materials. These include plastics and metals. Polyamide, aluminium and brass are particularly widely used for the production of profiles.
Edging profiles produced by machining are made of wood.
After shaping the basic profile, edging profiles can be completed with a series of cross holes along the fitting groove for the panel material. These holes accommodate screws that prevent the inserted panels from slipping out. Adhesive joints are an alternative to screwing the panels together. This is especially true for materials that cannot be screwed together so easily, such as glass.
Use of edging profiles
The advantage of edging profiles is that they relieve the static load on the installed panel. An installed panel is always supported stress-free. The risk of cracks is thus significantly reduced or even eliminated. Additional expansion strips in the frame made of edging profiles also absorb thermal deformations of the installed panel. The framework of the edging profiles dissipates all external forces and keeps them away from the installed panels. This makes the edging profile ideal for holding panels made of fragile material. Window construction is therefore the most widespread use of edging profiles. In addition, edging profiles are used wherever large panels need to be securely mounted. Their stability and simple processing make them particularly popular for the following applications:
- Advertising boards
- furniture construction
- Interior fittings
- laboratory technology
Edging profiles can be easily sawn, drilled and glued. This gives them a high degree of versatility and makes very sophisticated constructions possible
