Steel Buildings in Europe

Part 10: Model Construction Specification 10 - 25 8 PREPARATION AND ASSEMBLY This Section specifies the requirements for cutting, shaping, holing and assembly of constituent steel components. Structural steelwork shall be fabricated considering the surface treatment requirements in § 10 of EN 1090-2, and within the geometrical tolerances specified in § 11 of EN 1090-2. 8.1 Identification At all stages of manufacturing, each piece or package of similar pieces of steel components shall be identifiable by a suitable system, according to the requirements of § 6.2 of EN 1090-2. 8.2 Handling and storage Constituent products shall be handled and stored in conditions that are in accordance with product manufacturer's recommendations. Structural steel components shall be packed, handled and transported in a safe manner, so that permanent deformation does not occur and surface damage is minimized. Handling and storage preventive measures specified in Table 8 of EN 1090-2 shall be applied as appropriate. 8.3 Cutting Known and recognized cutting methods are sawing, shearing, disc cutting, water jet techniques and thermal cutting. Hand thermal cutting shall be used only if it is not practical to use machine thermal cutting. Cutting shall be carried out in such a way that the requirements for geometrical tolerances, maximum hardness and smoothness of free edges as specified in § 6.4 of EN 1090-2 are met. 8.4 Shaping Steel may be bent, pressed or forged to the required shape either by the hot or by the cold forming processes, provided the properties are not reduced below those specified for the worked material. Requirements of § 6.5 of EN 1090-2 shall be applied as appropriate. 8.5 Holing Dimensions of holes, tolerances on hole-diameters and execution of holing shall comply with the requirements of § 6.6 of EN 1090-2.
