Cast iron ornamental fencing became popular in the early 1900’s due to the cost efficiency of manufacturing the different components of ornamental fencing. Cast iron utilizes molds for the different parts. Steel is melted to extreme temperatures and poured into molds. Once cooled the parts are separated from the molds, cleaned of burns and excess edges and ready for painting. There are several large manufacturers who supply primarily welding sloops who produce the bulk of cast iron ornamental fencing in today’s market.
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.
