GOST 8509-93 PDF

Full title and description

GOST 8509-93 — Уголки стальные горячекатаные равнополочные. Сортамент (English title: "Hot-rolled steel equal-leg angles. Dimensions"). The document defines the assortment (dimensions), cross-sectional areas, reference axes values and mass per metre for hot‑rolled equal‑leg steel angles.

Abstract

GOST 8509-93 is an interstate (GOST) standard that sets the dimensional series (sortament) and related geometric and mass characteristics for hot‑rolled equal‑leg (equal‑sided) steel angle profiles. It provides tables and figures with nominal sizes, recommended corner radii and reference values used for design, procurement and manufacture of angle sections. The standard is intended to be used alongside material and mechanical‑property standards that specify the steel grades and delivery conditions.

Scope

The standard applies to hot‑rolled equal‑leg steel angles (L‑sections with equal flange widths). It establishes the assortment (standard sizes), nominal dimensions (flange width, thickness), recommended internal corner radii, cross‑sectional area, reference axis values (for calculation and design), and mass per metre for each size. GOST 8509-93 is limited to geometric and assortment requirements; requirements for steel grades, mechanical properties and surface condition are referenced to other normative documents.

Key topics and requirements

• Standardized assortment (sortament) of hot‑rolled equal‑leg angles (list of nominal flange widths and thicknesses).
• Nominal dimensions and tolerances for flange width, thickness, and corner radii.
• Tabulated values: cross‑sectional area (F), mass per metre (kg/m), and section moduli / moments of inertia (reference values for design calculations).
• Reference axes and geometrical centre data for use in structural calculations (axes offsets, polar moments where provided).
• Normative references to international standards for angle sections (e.g., ISO 657 series) and to related national GOSTs that cover material and delivery requirements.
• Provisions for recommended additional tables (appendices) for export shipments (recommended applications for export markets where specified).

Typical use and users

GOST 8509-93 is used by structural engineers, metal‑work designers, fabricators, steel producers, suppliers and procurement specialists in construction and manufacturing. Typical applications include welded and bolted steel frameworks, bracings, racks, machinery frames, and general structural components where hot‑rolled equal angles are specified. The standard provides the dimensional basis used in drawings, bills of materials and supplier specifications.

Related standards

Commonly referenced and related documents include: ISO 657 (series) for metric steel angles, GOST standards covering steel chemical/compositional and delivery requirements (examples: GOST 380, GOST 535 series for carbon steels and their quality grades), and GOST 8510 (standards for unequal‑leg angles / sortament). The standard also replaces earlier national versions in the GOST 8509 series (for example 8509-86 / 8509-72 in historical sequence).

FAQ

Q: What is this standard?

A: GOST 8509-93 is the interstate standard that defines the dimensional assortment and related geometric data for hot‑rolled equal‑leg (equal‑sided) steel angles — essentially the standard list of L‑section sizes and their nominal properties.

Q: What does it cover?

A: It covers nominal dimensions (flange width, thickness), recommended corner radii, cross‑sectional areas, mass per metre, and reference axis/section property values for hot‑rolled equal‑leg steel angles. It is primarily a dimensions/sortament standard; material quality and mechanical requirements are handled by other GOSTs.

Q: Who typically uses it?

A: Structural and mechanical engineers, steel fabricators, metal suppliers, procurement staff and standards libraries — anyone specifying, procuring or designing with hot‑rolled equal‑leg steel angles in jurisdictions that recognize GOST standards (CIS countries and users of Russian/CIS normative practice).

Q: Is it current or superseded?

A: As of available authoritative registries and standards libraries the document is listed as действующий (active). It was registered in 1993, adopted in the mid‑1990s and introduced into force on 1 January 1997; later reprints and compilations exist. Users should confirm the current status with their national standards body if required for regulatory compliance.

Q: Is it part of a series?

A: Yes — GOST 8509 is part of a family of standards for steel angle sections (historical editions include earlier GOST 8509-72 and 8509-86). Related numbering (e.g., GOST 8510) covers non‑equal (unequal‑leg) angles; ISO 657 provides an international counterpart.

Q: What are the key keywords?

A: Equal‑leg angle, hot‑rolled, sortament, dimensions, steel angles, L‑section, mass per metre, section properties, GOST 8509-93.
