Surface treatment options for aluminium sign frame extrusions

Mill finish

Mill Finish refers to the original surface condition of the aluminum sign frame extrusions after extrusion, retaining the natural appearance of the metal.

Anodized surface treatment

This is an electrochemical process used to protect the surface of aluminum sign frame extrusions, forming a corrosion-resistant coating through oxidation.

Powder coating finish

A powder made from a mixture of resins and pigments is applied to the surface of the aluminum sign frame extrusions.

Powder coatings provide UV resistance and corrosion protection, with a variety of color options.

Electrophoretic coating

Using electrophoretic technology, the coating adheres evenly to the surface of the aluminum sign frame, enhancing both corrosion resistance and aesthetics.

Sandblasting surface treatment

Fine sand particles are projected at high speed to impact the aluminum surface, removing the oxide layer, dirt, and other impurities while creating a fine texture on the surface.

Chemical polishing surface

This is a chemical polishing method that involves immersing the extrusions in a strong oxidizing agent to achieve a super bright mirror finish.

Manufacturing process of aluminium sign frame extrusions

Cold extrusion

Process Overview: This extrusion method is performed at room temperature. As long as the mold is strong enough to withstand the stresses produced during extrusion, cold extrusion is an ideal choice for manufacturing aluminium sign frames.

Cold-processed aluminium sign frame extrusions have high strength.
They feature tighter tolerances and an excellent surface finish.

Hot extrusion

Process Overview: This extrusion occurs within 50-75% of the melting temperature of aluminium.

It requires higher pressure and temperature.
Good lubrication is essential.
While the cost of hot extrusion is relatively high, it is suitable for producing complex shapes and large-sized aluminium profiles.

Hydrostatic extrusion

This method uses pressurized liquid to envelop the aluminium workpiece, reducing the required force and impact during extrusion.

It lowers the force requirements in the extrusion process, enhancing production efficiency.

How to install aluminium sign frame extrusions?

Aluminium sign frame extrusions come in two different designs: slide-in and bolt-on.

To install the slide-in frame, simply slide it in from the top. You may also need to secure the sign in place with bolts to ensure it stands upright.

For bolt-on aluminium sign frame extrusions, screw holes are located along the edges of the frame. Use bolts to firmly attach the sign to the frame, ensuring its stability.

Differences between aluminium sign frame extrusions and stainless steel sign frame extrusions

Weight: Aluminium is lighter, making it suitable for lightweight applications.
Complex Extrusion Profiles: Aluminium can be manufactured into complex profiles, allowing for flexible designs.
Assembly and Transportation: Aluminium is easy to assemble and transport, reducing logistics costs.
Cost: Aluminium has a lower production cost, making it ideal for mass production.
Cleaning: Aluminium is easy to clean and maintain.
