  • Despite the emergence of new materials, cast iron remains a mainstay due to its cost-effectiveness. It is relatively inexpensive compared to alloys like stainless steel, yet it delivers comparable strength and durability. Moreover, its recycling potential adds to its environmental sustainability.

  • Once your iron fence is free from rust, dirt, and debris, you can paint it to add an extra barrier between the iron and the elements, further preventing oxidation. Painting your fence can also enhance its beauty, and of course, you can choose any color and style you think suits it best. After the paint has dried, it’s also a great idea to apply a coat of all-weather sealant to really ensure it is protected from weathering.

  • Fence brackets are unique to wrought iron fences and often used to hold the fencing components to the posts. These slide over the rails, are set against the posts and are often then secured with a self-tapping screw to hold everything together. Aluminium fencing does not use brackets. Instead, rails are slid into punches in an aluminium post and then a self-tapping screw is driven through the post and into a rail inside it in order to secure everything.

  • The two aluminium extrusions are separated from each other by the polyamide strips. This allows the inside and outside of these types of profiles to have different colours. In addition, polyamide has a very good dimensional stability owing to its extremely small expansion coefficient. Polyamide is specifically resistant to very high and very low temperatures. The insertion of the strips therefore has no effect on the structural strength and durability of your window profiles. All this ensures that thermal break profiles offer almost unlimited possibilities in terms of aesthetics and design.

Powder coating can maintain its finish for up to 15-20 years, depending on pre-treatment and the type of powder. Its resistance to weather, corrosion, and chemicals makes powder coating a more durable finish than paint or other liquid coatings.
