- .jpgThis group of metal products includes hot-rolled and roll-formed profiles manufactured as per GOST 7511-73 and intended for fabrication of window and lantern transoms and window panels of industrial buildings.

Depending on profile accuracy, roll-formed profiles are made of:
• –high accuracy
• –standard accuracy.
Profiles can be:
• gauge length;
• multiple gauge length;
• off gauge length.
Upon the agreement reached between parties it is possible to fabricate profiles of limited length within the limits of off-gauge length.
Length of hot-rolled profiles cut by machine press is measured excluding rumpled surface.
Profiles shall be made of steel grade 3 with chemical composition and specified parameters for hot-rolled profiles – 2d category acc. to GOST 535-88; for roll-formed profile – 4th category acc. to GOST 16523-89 , 2d category acc. to GOST 14637-89.
