Our range of products for heavy-duty use includes box channels, slotted channels, point drainage outlets and manhole covers with an increased material thickness as well as models made from concrete and polymer concrete. The portfolio is rounded off with gratings made from stainless steel, hot-dip galvanised steel or cast iron, produced to fit the exact dimensions of our channels. The heavy-duty range satisfies the requirements of up to load class E 600, depending on the requested product variant and design.
