Cold drawn seamless
We supply cold drawn seamless (CDS) tubes for both mechanical and hydraulic applications.

If your application is mechanical, then we would normally offer CDS to BS EN 10305-1 E235+C although higher strength grades are available to order.

If your application is hydraulic or pneumatic, then we would offer CDS to BS EN 10305-4 E235+N. The N signifies that the tubes have been normalised to improve their suitability for bending. Our standard product is uncoated but if you require a corrosion resistant coating we can offer various options to order.
