STEEL STRIP for CABLE ARMORING - GOST 3559-75, analogous to ASTM A 459-88 - — ОАО "Магнитогорский Метизно-Калибровочный Завод"

Products catalogue

Application: cables protection against mechanical damage.

The steel strip is made from steel grades 08 (ps, kp), 10 kp according to GOST 1050.

The steel strip is manufactured of 2 groups:

A – galvanized;

B – without any coating.

B – PI steel strip, produced by wide steel strip cutting (up to 300 mm wide).

A group steel strip is subdivided into subgroups:

Apl – hot-dip zinc coated or galvanized, for flat armor manufacturing;

Anpl – galvanized, for profile armor manufacturing;

Aprll – hot-dip zinc coated, for profile armor manufacturing

According to zinc surface density A group steel strip is subdivided into 2 classes:

1st class – zinc surface density on both sides is not less than 200 g/m2;

2nd class – zinc surface density on both sides is not less than 100 g/m2.
