History
The company was founded by Hermann Krages (1909-1992), son of a Bremen merchant on wood and fiberboard and brother of racer Louis Krages. He is known most of today because of his speculation in the German stock market. Krages was originally given a fiberboard plant in the East Prussia Ore Mountains by his father, who disappeared at the end of World War II. He then moved to Scheuerfeld where he acquired the Berger paper mill and started the "Deutsche Duroleum Gesellschaft", making the fiberboard plate again. He expanded with new factories in Etzbach, HÃÆ'¶xter an der Weser, Leutkirch im AllgÃÆ'¤u and in Bremen. The company in Weert was founded in 1960.
Initially the company focused mainly on sales and storage panels manufactured at the German plant in Leutkirch. Gradually switch to the production of hardboard for the mattress. This activity was later incorporated into the Thermopal company after Krages sold its holdings due to stock market speculation in the 1960s. In 1964 the name changed to "Weerter Plastics Industry" ("Weerter Kunststoffen Fabrieken", or WKF). In 1967, the company was acquired by Hoechst, who used his product to surface in his laboratory. In 1991 the company handed over to HAL Holding NV.

Producing
Trespa Plates are made by compressing impregnated paper or wood fiber and epoxy, phenolic or polypropylene resins at high pressure and high temperature. Special surfaces made with Electronic Beam Curing, a coating technique developed by Trespa, ensure durability and scratch resistance. Due to the ability to add colored pigments to the surface during the drying process, various colors are possible. Production techniques for plates, made of wood, also called "Dry Forming" technology. In this technique, pre-pregs is cheaper than the more expensive impregnated paper layers in the production of fiber boards applied. These prepregs consist of wood fibers and thermosetting resins. This technique was applied for the first time in 1984. Because the Plate Trespa surface has a solid molecular layer, it is almost resistant to weather (temperature, UV radiation and moisture). Also, any contamination, such as graffiti, can be removed easily. Due to these advantages, this material has been popular since the 1980s in the production of laboratory surfaces and outdoor signage, but also for shower stalls and toilet cubicles in educational facilities, hospitals, and campsites.
Now Trespa brings HPL Trespa panel with various brand names, with different quality for indoor and outdoor applications. Other names are used for Trespa Athlon furniture, Trespa Virtuon for indoor applications, Trespa TopLabPLUS, Toplab, for labs and Trespa Meteon for outdoor applications.
