Packing
Standard packing in hexagonal or rectangular bundles, banded with metal strips

Available form of delivery:
Steel tubes are supplied without further heat treatment after rolling and welding.

Laboratory Tests:
Before any product leaves our works sample from each batch manufactured are subjected to stringent metallurgical and mechanical laboratory tests.

These tests cover bending, flattening, and expansion through cones in compliance with the requirements of EN 10305-3 (DIN2394) and EN 10305-5 (DIN 2395), EN 10219. Special tests requested by the customer may also be carried out by arrangement. Each delivery is accompanied by a quality certificate, certifying the origin of the product and its properties.

Logistics

Due to our strategic location we are able to deliver our products by rail, river, sea or overland.
