Steel Products Specifications
The present specifications are intended to support the mill’s Marketing and Sales Service in its
precontract negotiations with customers. The mill’s internal quality requirements to the rolled products and
production methods are set forth in Process Sheets and Quality Plans.
I. REINFORCING STEEL BARS
Reinforcing steel bars are manufactured both in lengths and in coils. The maximum and the
minimum bundle lengths are 12 m and 6m, respectively. Reinforcing steel bars in cut lengths are normally
manufactured in nominal diameters from 8 to 40 mm (dia. 28, 32, 36 and 40 mm are less preferable and
orders for these sizes shall be limited in number), with the size series depending on the standard for a
specific type of product and being limited by the above specified range of sizes. Reinforcing steel bars are
manufactured hot rolled - without special cooling, with cooling at final stages (to reduce final rolling
temperatures to avoid recrystallization) and with thermal hardening (an intensive water
cooling).
Reinforcing steel bars in coils are manufactured in nominal diameters:
- from 5,5 to 14,0 mm – plain round bars;
- from 6 to 14,0 mm – hot rolled ribbed reinforcing steel bars;
- from 8 to 12,0 mm – thermally treated ribbed reinforcing steel bars (depending on the class of
strength).
The coil weight is 1350 ± 150 kg. In the course of manufacturing, coils of less than 1000 kg in
weight may be formed, therefore, a portion of coils from 500 to 1200 kg in weight, say up to 2% of a lot
quantity, is recommended to be agreed upon when negotiating orders.
As of today, the steel products have been approved against the following national standards:
BS 4449-97 (UK), DIN488-84/86 (Germany), LNEC E449-98 (Portugal), LNEC E450-98
(Portugal), STO ASChM 7-93 (Russia).

Steel Products Specifications II. Profiled bars
Steel profiled bars are manufactured in lengths from 6 m to 12 m.
The range of profiled bars includes the following products:
- equal side hot rolled steel angle bars to GOST 8509-93; DIN 1028-76 in sizes: 25×25×4; 30×30×4;
32×32×4; 35×35×4; 35×35×5; 40×40×4; 40×40×5; 45×45×4; 45×45×5; 50×50×4; 50×50×5;
50×50×6.
Steel profiled bars are manufactured hot rolled with the use of an accelerated water cooling and
without any special cooling methods.
The bundle weight is up to 10.
