Hollow sections

Cold formed profiles

Cold formed profiles (cold-rolled) are made in accordance with EN 10219. They have many advantages over open steel sections:

less weight and more favorable shape
lighter construction,
the possibility to obtain the larger span of construction,
faster time of making elements and structures,
less work during finishing and renovation of the surface,
reduction of production costs,
lower operating costs,
greater aesthetics.

The range of available dimensions:

square: 15 x 15 mm - 400 x 400 mm
rectangular: 20 x 10 mm - 500 x 300 mm

The range of available wall thickness:

1,5 – 16 mm

The range of available length:

commercial length of 6 m or 12 m
special lengths on request
the possibility of cutting to the exact length

Hot-rolled profiles

Hot-rolled profiles are made in accordance with EN 10210 standard. During production they are subjected to temperatures of 900-1000 ° C, which enables to get the following benefits:

homogeneous internal structure (impact and stretch values are identical over the entire length of the section),
greater plasticity than in the case of cold bent profiles (resulting from the lack of internal tensions),
smaller bending radius (significant increase of the area possible to be welded),
wider cross-section of dimensions and wall thickness

We have in stock hot-rolled profiles in grades S355J2H and S355NH (normalized) with 3.1 certificate according to EN 10204.
