It is of utmost importance to us and our manufactures that the highest quality materials are used to create the beautiful playground equipment that we offer. Browse through the descriptions below of the main materials that are used for more information.

Each manufacture has their own standard color choices but many times any RAL color may be requested for an additional cost. Take a look at the  Conlastic color choices for steel and the Conlastic color choices for rubber here.

See the options for the EPDM color choices from Kraiburg - EuroFlex here.

No decay areas, less and substantially smaller shakes:

K&K uses laminated robinia wood because it is a construction material which hardly generates any shakes. This special process was developed by K&K and trade marked as Karolam®.

The laminated robinia wood is manufactured from preselected lumber with no defects. The spiral grain, often visible in the shakes, is removed in several constructive stages. The individual lamellas are pre-dried to 12-14% before they are glued and at the same time the especially high tensions characteristic of the robinia wood are eliminated.

For the gluing, the lamellas are placed in such a way that the residual tension in the wood material is virtually eliminated.

Higher bearing strength and increased installation lengths and heights:

Because it consists of dried wood and is composed of multiple layers, the laminated wood also possesses and increased bearing strength of up to 50%. This then allows for higher installation lengths or heights, respectively. Post lengths up to 14 m are possible.

Better surfaces with higher durability:

The integrated industrial production process of the laminated wood, from preselection, drying and removal of defects to gluing and circular milling enables us to manufacture a considerably higher surface quality of the material. The circular milled posts are abraded with 240 grain size and furnished with a surface finishing especially developed for this purpose (used for posts and pedestals since May 2009). This improved conditioning (lotus effect) lengthens the life cycle of the wood and the UV-stability of the natural robinia wood coloring. The “greying effect” of the wood surface does not occur.

Most of the galvanized steel that our manufacturers offer is available in powder coated or coated in a 2-component polyurethane finish.

Wood from most of our manufactures is FSC certified (Forest Stewardship Council).
The FSC developed 10 principles and 56 indicators as standards that encompass their vision for forest management. Forests, which are managed in accordance with these standards, can be labelled with FSC certification. Consumers who buy FSC labelled products, make an active contribution to sustainable management of forests around the globe. To learn more about the FSC, visit their website at www.fsc.org

We are using Southern Yellow Pine that is treated with ACQ which is a non-arsenic treatment that preserves the wood from termite attack. Southern Yellow Pine is one of the strongest wood options in America and compares in strength to Douglas Fir.

Kraiburg, “EuroFlex” rubber surfacing, has no waste in their production process as all material goes back in the production cycles for other products. See their USGBC certificate (US Green Building Council) here and a learn about their company and processes on the Kraiburg overview video.

All recycled rubber used by Kraiburg are from tires that originate in Europe and are supplied by only well-known sources. This allows for tight quality control and material consistency. The Swiss EPDM rubber is of the highest quality and has excellent UV protection for long lasting vibrant colors.

Our manufacturers use a high quality stainless steel grade 304 which is used throughout all type of industries.

All stainless steel is iron-based alloy, i. e. the iron (Fe) content amounts to at least 50%. Steel is classified to be “stainless” if it does not rust after it has been in contact with water or humid air even after a prolonged period of time. Rust itself mainly consists of a combination of iron hydroxide (Fe OH3) and iron oxides.

Stainless steel owes its rust-resistant quality mainly to the alloy metal chromium (Cr). Chromium forms chromium oxide on the surface of the steel and results in a so-called passive condition, i. e. the electrochemical property of the steel surface is similar to that of precious metal, such as silver, platinum or gold.  Additionally, nickel (Ni) increases the general strength and resistance to corrosion.

Our manufacturers generally use the chromium-nickel alloyed quality with the material no. 1.4301. When compared to chromium steel it shows a significantly improved resistance to corrosion.

Stainless steel is – with the exception of reducing acids and chlorine containing agents – resistant to corrosion, and above all does not need additional surface treatment, once it has been glass bead blasted. The raw material and energy-intensive manufacture yields an almost perfect recycle-ability of materials.

Most of our manufacturers use stainless steel polished by a process of glass bead blasting. The glass bead blasting substances applied are absolutely free of harmful substances and friendly to the environment. The polished stainless steel gives an attractive shine that will last for a lifetime.
