![POLIESTER Interior [INT]](https://bp2.eu/wp-content/uploads/2022/03/powloka-int-www.jpg)
Sheet metal coated with a 15 μm polyester layer with a smooth and glossy surface. Due to the low thickness of the organic coating, it is mainly intended for interior applications and building elements not directly exposed to weathering.
Available colours
![POLIESTER Standard [RAL]](https://bp2.eu/wp-content/uploads/2022/03/powloka-ral-www-gloss-3.jpg)
Basic organic coating with a thickness of 25 μm. The surface is uniform, smooth – shiny or metallic. A material with a very wide range of applications. It is available in a wide range of colours described by means of a universal RAL chart.
Available colours
![HERCULIT [HC]](https://bp2.eu/wp-content/uploads/2022/03/powloka-hc-www.jpg)
It is a coating developed in close cooperation with a leading manufacturer of varnishes for the best steel mills in Europe. Many years of studying existing coatings and monitoring customer needs, with particular emphasis on the needs of roofers, have allowed us to condense so many different advantages into one product. HERCULIT is a polyurethanecured polyester with a high resistance to mechanical damage and a thickness of 35 μm.
Available colours
![MULTILAYER [MLT]](https://bp2.eu/wp-content/uploads/2022/03/powloka-ml-www.png)
35 μm thick polyester paint with Z275 zinc layer or ZM120 zinc-magnesium layer. It is characterised by its wood structure and adequate protection against corrosion and UV radiation. This combination allows outdoor use, especially where high weather resistance and high aesthetics are required.

XCarb® steel comes from more sustainable production processes that reduce CO2 emissions through the use of modern technologies such as recycling, reduced energy consumption, and the implementation of renewable energy sources. XCarb® offers steel with a sustainable profile, ideal for companies aiming to reduce their carbon footprint.
Low-emission XCarb® steel is produced in electric arc furnaces from materials that are 75% recycled and using only renewable electricity. The carbon footprint when using low-emission XCarb® steel is approximately 62% lower compared to standard solutions where the sheet is coated with organic coatings.
Despite reduced CO2 emissions, the steel retains its excellent mechanical and strength properties, comparable to traditional steel products.
