Steel sills have enjoyed enormous popularity among customers for many years. The first and foremost reason is surely that they are the least expensive option but can survive even decades, provided they are properly maintained by the building owner to extend their service life. It is also important that the steel window sills are protected with properly matched end caps. Otherwise their ends will corrode over time as a result of adverse weather conditions, especially when exposed to water. Additionally, the steel sills produced by us are covered with special protective film, which increases their basic resistance to weather and provides resistance to cleaning agents, thus making their maintenance easier. They are available in many lengths and widths to suit individual needs of our customers. The sills are available in RAL colors as well as in structural colors.
