Product Information
EN10219-1 EN10219-2 Cold Formed Welded Structural Hollow Sections of Non-Alloy and Fine Grain Steels
Part 1: Technical delivery condition
Part 2: Tolerances, Dimensions and Sectional Properties
Structural hollow section manufacturing process:
Structural hollow sections are manufactured by electric weding or submerged arc welding without subsequent heat treatment. Hollow sections manufactured by a continuous process shall not inlude the welds used to join the lengths of strip prior to formning the hollow section, except that for hlically welded submerged arc-welded (SAW) hollow sections, such welds shall be permitted when tested in accordance with 9.4.3.0 EN10219-1, EN10291-2.
Delivery conditions:
The hollow sections are delivered cold formed without subsequent heat treatment except that weld seam maybe in the as welded or heat treated condition
NOTE: For SAW hollow sections above 508 mm outside diameter it may be necessary to perform a warm shaping operation, which does not affect the mechanical properties, in order to meet the out-of-roundness tolerance requirements.
Suitability for hot dip galvaninzation:
The products are sutibale for hot dip galvanization.
TABLE 1 Tolerances
Symbol | Unit | Definition |
B | mm | Nominal length of side of square hollow section.Nominal length of the shorter side of a rectangular hollow section |
C1/C2 | mm | Length of corner region of a square or retangular hollow section |
Dmax/Dmin | mm | The maximum and minimum outside diameter of a circular hollow section measured in the same plane |
H | mm | Nominal length of the longer side of a rectangular hollow section |
M | Kg/m | Mass per unit length |
T | mm | Nominal thickness |
O | % | Out-of-roundness |
T | mm | Nominal thickness |
V | mm | Total measured twist |
TABLE 2 Tolerances
Characteristic | Circular hollow sections | Square and rectangular hollow sections | |
Outside dimensions (D,B andH) | ±1% with a minimum of ±0.5mm and a maximum of ±10mm | Side length (mm) | Tolerance |
H,B ＜100
100≤H,B≤200 H,B＞200 | ±1% with a minimum of ±0.5mm ±0.8% ±0.6% | ||
Thickness(T) | For D≤406.4mm: T≤5mm ±10% T＞5mm ±0.50mm For D＞406.4mm: ±10% with a maximum of 2mm | T≤5mm ±10% T＞5mm ±0.50mm | |
Out-of-roundness(O) | 2% for hollow sections having a diameter to thickness ratio not exceeding 100① | —— | |
Concavity/convexity② | —— | Max. 0.8% with a minimum of 0.5mm | |
Squareness of side | —— | 90° ±1° | |
External corner profile | —— | See table 3 | |
Twist(V) | —— | 2mm plus 0.5mm/m length | |
Straightness | 0.20% of total length | 0.15% of total length | |
Mass(M) | ±6% on individual lengths | ||
①Where the diameter to thickness ratio exceeds 100 the tolerance on out-of-roundness shall be agreed.
②The tolerance on convexity and concavity is independent of the tolerance on outside dimensions.
TABLE 3 External Corner Profile
Thickness T mm | External Corner Profile C1,C2,or R1 mm |
T≤6 6＜T≤10 10＜T | 1.6T to 2.4T 2.0T to 3.0T 2.4T to 3.6T |
The sides need not be tangential to the corner arcs.
TABLE 4 Tolerances on length①
Type of length | Range in mm | Tolerance |
Random length | 4000 to 16000 with a range of 2000 per order item | 10% of sections supplied may be below the minimum for the ordered range but not less than 75% of the minimum of the range |
Approximate length | ≥4000 | ﹢50mm 0 |
Exact length | ＜6000 ≥6000 to ≤10000 ＞10000 | ﹢5mm 0 ﹢15mm 0 ﹢5mm +1mm/m 0 |
①The purchaser shall indicate in the enquiry and order the type of length required and the length range or length required.
