1 When calculating the mass, the density of steel is assumed to be 7.85 g / cm ; mass of zinc coating applied to 1 m from both sides of the sheet, is assumed equal to 414 g. The mass of the paint and varnish coating was not taken into account.

2 Data on the geometric characteristics of the profiles (moments of inertia and resistance) are reference and obtained, allowing the working width () of flat sections of compressed shelves equal to:  — when determining the moments of resistance;  — when determining the moments of inertia.

3 Reference values per 1 m of width are obtained by dividing the calculated characteristics by the width . Weight 1 m is obtained by dividing the mass of 1 m length by width .

3.4 Profiled sheets should be manufactured in length:

— a multiple (250 mm) measuring length from 3 to 12 m — for flooring (types H and HC);

— a multiple (300 mm) measuring length from 2.4 to 12 m — for wall fences (types HC and C).

As agreed by the manufacturer and the customer, it is allowed to produce profiled sheets of any length, and also less than 3 and more than 12 m in length for the flooring.

5 Acceptance rules

5.1 The acceptance of profiled sheets is done in batches.

The lot weight must not exceed 75 tons. The lot must consist of packages. The weight of the package should not exceed 10 tons.

5.2. To monitor the quality indicators for compliance with requirements 4.2.3 and 4.3, one top sheet from each package of one batch of profiled sheets is selected.

It is allowed to control one sheet from the first and last packets of one lot, if the established quality indicators are provided by the production technology.

5.3 The party is considered accepted if the quality indicators comply with the requirements of this standard.

6 Methods of control

6.1. The grade, properties, thickness of rolled products, as well as the quality of the paintwork of the original blank, must be certified by a document on the quality of the billet manufacturer.

6.2. The surface quality of the metal and paintwork of the profiled sheets is determined visually.

6.3 The dimensions of the profiled sheets are controlled by a tape measure in accordance with GOST 7502, a metal ruler in accordance with GOST 427, and shorthandreism according to GOST 164. The width and height of the sheets are measured at a distance of 40 to 500 mm, the length at two sides.

The general sickle-spot is determined with the help of a string fixed on a flat horizontal surface and a ruler in accordance with GOST 427.

6.5. The cut-off cut of profiled sheets is measured with a ruler in accordance with GOST 427 and with a square in accordance with GOST 3749, installed along the extreme corrugation profile.

6.6 For the measurement result of 6.3−6.5, the average value obtained with three measurements in one section or one line is taken, with the results of each measurement being within the limits of the standard tolerances.

6.7 To control longitudinal joints of profiled sheets of each type in accordance with requirements 4.3.3 periodically, at least once a quarter, a control assembly is carried out.

Assembly must be carried out freely, without additional mechanical influences, with the extreme narrow shelves overlapping the wider extreme shelves.

6.8 The dimensions and shape of the profiled sheets may be checked by other means of measurement, approved in accordance with the established procedure and ensuring the necessary measurement accuracy.
