Standard our twin rods are made of spring steel class C (DIN 17228). However we can also make twin rods of CrSi-steel, stainless steel or glass fibre. After consultation with you, we can also use other materials so that the produced web will meet your expectations as good as possible.
For use in rough circumstances, for instance in stone separators, we can make the rods out of stronger materials. Here we use CrSi steel (spring steel, class super C) CrSi steel is harder and tougher than spring steel class C. Furthermore it has all the properties of regular spring steel. CrSi steel is available in the diameters 8, 9, 10, 11 and 12mm. A great advantage of CrSi steel is the fact that it is very suitable for welding.
Stainless steel is often used in water. All metals used in the sieve web are then of stainless steel. It is not possible to make a centre flattening in a stainless steel rod. If a centre belt is required, attachment onto the belt will be made with centre clips. Stainless steel is available in the diameters 6, 8, 10 and 12mm.
To save weight we can use rods out of glass fibre. The glass fibres provide great tensile strength. A sieve web with these rods can weigh up to 50% less than a web with steel rods. Another advantage is that these rods don’t rust. Glass fibre rods are available in the diameters 6, 8 and 10mm.
