Name in Russian:
ГОСТ 19903-2015
Hot-rolled steel sheets. Dimensions
Full title and description
GOST 19903-2015 — "Hot-rolled steel sheets. Dimensions". An interstate standard that specifies the assortment (dimensions, sheet and coil sizes) and related delivery forms for hot-rolled flat steel products.
Abstract
This standard defines the dimensional assortment, nominal thickness and width ranges, formats (sheets and coils) and basic assortment rules for hot-rolled steel sheet products intended for general industrial and construction use. It establishes which sizes and delivery forms are standardised while referring material properties and composition to related GOSTs.
General information
- Status: Current / active (introduced as an interstate standard and adopted as a national standard of the Russian Federation).
- Publication date: 2015 (official introduction/adoption into national practice: 1 September 2016).
- Publisher: Interstate standard (adopted via the Federal Agency for Technical Regulation and Metrology — Rosstandart / Interstate Council for Standardization).
- ICS / categories: 77.140.50 (Metallurgy — Iron and steel products; flat steel products and semi-finished products).
- Edition / version: GOST 19903-2015 (replaces GOST 19903-74).
- Number of pages: 16 pages (typical published text length).
Scope
The standard applies to hot-rolled sheet and coil products having a width of 500 mm or more. It covers sheet thicknesses from about 0.4 mm up to 160.0 mm in cut sheets, and coils with thickness from about 1.2 mm up to 25.0 mm, specifying the standard nominal sizes, customary cutting formats and basic delivery assortment for general-purpose hot-rolled flat steel. It does not set chemical composition or mechanical property requirements, which are covered by other GOSTs.
Key topics and requirements
- Standard nominal thickness ranges and tolerances for hot-rolled sheets and coils.
- Approved widths and standard cutting formats (common sheet widths and standard length options).
- Assortment rules distinguishing sheet forms and coil supply, including minimum widths and thickness bands.
- Delivery forms, basic marking/identification and packaging/transport recommendations for flat products.
- References to other GOSTs for chemical composition, mechanical properties and surface requirements (this standard focuses on dimensions/assortment, not metallurgy specifications).
Typical use and users
Used by steel producers (mills), metal service centres and distributors, fabricators, procurement specialists, structural and mechanical engineers, construction and shipbuilding companies, and quality/inspection personnel who need a harmonised dimensional assortment for hot-rolled sheet and coil products across the CIS and Russian markets.
Related standards
Replaces/supersedes GOST 19903-74. It is used together with standards that specify chemical composition and mechanical properties (for example, standards covering steel grades and mechanical tests) and with other flat-products standards in the GOST system (several referenced GOSTs are indicated in the normative references of the text).

FAQ
Q: What is this standard?
A: GOST 19903-2015 is the interstate standard that defines the dimensional assortment (standard sizes, sheet and coil formats) for hot-rolled steel sheet products.
Q: What does it cover?
A: It covers nominal dimensions, standard thickness ranges, typical sheet cutting formats and coil thickness bands for hot-rolled flat steel with widths ≥ 500 mm; it does not specify chemical composition or mechanical properties (these are covered by separate GOSTs).
Q: Who typically uses it?
A: Steel mills, traders and distributors, metal service centres, fabricators, procurement, and engineers in construction, machinery and shipbuilding who need standardised dimensions for ordering and manufacturing.
Q: Is it current or superseded?
A: GOST 19903-2015 is the current edition (introduced into national practice on 1 September 2016) and it replaces the older GOST 19903-74.
Q: Is it part of a series?
A: It is part of the family of GOST standards addressing flat steel products and is cross-referenced with other standards that govern steel grades, chemical composition and mechanical properties. It should be used alongside those related GOSTs for complete specification of a product.
