Maintenance of metal door knobs is relatively straightforward, another reason for their popularity. Regular cleaning with a gentle soap solution helps remove dirt buildup and prevents tarnishing. For brass knobs, occasional polishing can restore their luster, while stainless steel knobs typically just require a quick wipe down to keep them looking their best. This ease of maintenance makes them a practical choice for busy homeowners or property managers.

4. Durability and Low Maintenance Aluminium frames are resistant to rust and corrosion, making them an excellent choice for various environments. The thermal break technology does not compromise the strength and integrity of the structure, which means these profiles can withstand harsh weather conditions while requiring minimal maintenance.

Aluminum profiles are mainly the product of the aluminum extrusion process, where an aluminum billet is passed through a die. The result — varying types of aluminum profiles that have wide uses across residential, industrial, and constructional spaces.
Additionally, aluminium profiles can be designed to accommodate multiple locking points, further enhancing security. These profiles can also be integrated with advanced locking systems and access control technologies, making them suitable for commercial applications.
But one of the most fundamental questions is: what material will your fence be made of?
Repaint Your Fence
Before you start painting, it might be a good idea to add a primer to your fence. Make sure you’re buying a primer that’s specifically made for metal, as these can be purchased with rust inhibiting qualities. Once you’ve applied your primer, choose your paint colour and use a small paint brush to cover all areas of your fence with a thin coat of paint. Allow the paint to dry fully before applying a second coat. We recommend a paint such as hammerite to re-coat paintwork when necessary.


6061 Aluminum Grade
The advantages of aluminum alloy 6061 are good processing performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy polishing, easy coloring film, good oxidation effect and other excellent features. Therefore, it also has many advantages in making doors and windows.
6063 Aluminum Grade
Aluminum alloy 6063 is an aluminum alloy containing silicon and magnesium, which has good plasticity, strength and corrosion resistance and is suitable for use in construction, furniture and industrial fields. It can improve its hardness and strength through T5 or T6. It can also improve its surface's wear resistance and aesthetics through anodizing treatment. It can also choose different profile types (standard or thermal break aluminum alloy) according to different opening methods (sliding windows, casement windows, top-hung windows, etc.). In terms of making doors and windows, the advantages of 6063 aluminum alloy are good corrosion resistance, plasticity and machinability, and good surface treatment effect.
You can drill, weld, stamp, bend, cut, and deep draw 6061 aluminum grade quite easily using cold working methods when in the annealed state.

In the doors segment, aluminium extrusion profiles offer numerous advantages over traditional materials such as wood or uPVC. One significant application is in the manufacturing of entrance doors, where aluminium profiles provide exceptional strength and security. The inherent rigidity of aluminium extrusions makes it difficult to break or damage, ensuring the safety of the building’s occupants.
