Holes

Profile Sigma is one of the most used cold-bended steel profile. In steel constructions of halls is used as spandrel beam and roof purlin as well as part of steel columns.

Fast and easy assembly is enabled by possibilty of preparing profiles with ready holes. There are 3 possible type of holes:

Ø 14
Ø 18
bean 19×25

Recommendations

Transport recommendations

In case of transport organized by client, vehicle should have open carrying platform, which enables loading with fork-lift trucks.
Galvanised profiles have to absolutely protected from getting wet.

Storage recommendations

Oil and passing galvanized sheets is a protection against white corrosion only during transport.
Steps stored in packages cannot be stored in the open air or in rooms exposed to moisture and variable temperatures. Zinc and allusine coatings, in particular, not yet influenced by weather conditions, and therefore without a protective zone, are sensitive to water condensate with limited air access (sheet plate stored in packaging). Particular attention should be paid to unloading in winter conditions and storage in heated warehouses. As a result of a significant temperature difference between the sheets, water precipitates.
Steps soaked during transport or storage should be dried, then put the profiles to spacers enabling free air circulation. After drying, galvanized (allusine) sections should be viewed and covered with a layer of preserving oil.
Steel sheets intended for longer storage should be viewed and then covered with a layer of machine oil – for galvanized and allusine sheets.
The result of not compliance with the above recommendations is the formation relatively quickly (for galvanized and allusine sheets it can be only a few days) of zinc corrosion – i.e. white, loosely related to the ground layers, not providing corrosion protection.

Product description

Profile Σ

Cold -headed construction profiles of the Z, C and σ type are made of cold -plated steel.

The large variety of strength parameters of the sections allows you to optimally select the amount of material needed.
