Full title and description

ISO 1035-2:1980 — Hot-rolled steel bars — Part 2: Dimensions of square bars. Specifies the metric series dimensions and tolerances for hot-rolled steel square bars, including tabulated widths, corner radii, sectional areas and masses per unit length.

Abstract

Gives nominal sizes and permissible tolerances for hot-rolled square steel bars in the metric series. The standard’s tables provide widths, recommended corner radii, sectional areas and mass per unit length for each preferred size.

General information

• Status: Published (International Standard; currently listed to be revised / to be replaced by ISO/FDIS 1035).
• Publication date: October 1980 (Edition 1, 1980-10).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 77.140.60 — Steel bars and rods; ISO/TC 17/SC 3 (Steels for structural purposes).
• Edition / version: Edition 1 (1980).
• Number of pages: 1 page (concise tabular format).

Scope

Defines the preferred metric sizes and associated dimensional data for hot-rolled square steel bars intended for general engineering and structural use. The scope is limited to geometric dimensions, corner radii and mass per unit length and does not by itself specify chemical composition or mechanical properties. The standard is part of the ISO 1035 series covering hot-rolled bars.

Key topics and requirements

• Preferred nominal widths for hot-rolled square bars and corresponding dimensional tolerances.
• Recommended corner radii to avoid sharp corners on hot-rolled squares.
• Tabulated sectional areas and masses per unit length for each nominal size.
• Reference to the ISO 1035 series practices for related shapes and tolerances (round, flat, etc.).

Typical use and users

Used by steel producers, distributors, fabricators and design/engineering teams to select standard square bar sizes, to specify deliveries and to compute mass and section properties for design, procurement and inventory. Also used by standards bodies and testing/inspection organizations as the dimensional benchmark for hot-rolled square bars.

Related standards

ISO 1035 is a multipart series. Closely related parts include ISO 1035-1:1980 (Dimensions of round bars), ISO 1035-3:1980 (Dimensions of flat bars) and ISO 1035-4:1982 (Tolerances). A consolidated replacement (ISO/FDIS 1035) has been/was under development to cover dimensions, shape, masses and tolerances across the series.

FAQ

Q: What is this standard?

A: ISO 1035-2:1980 is an ISO international standard that specifies the metric-series dimensions and tolerances for hot-rolled square steel bars (concise table of sizes, corner radii, areas and masses).

Q: What does it cover?

A: It covers nominal dimensions, recommended corner radii, sectional areas and masses per unit length for preferred sizes of hot-rolled square bars. It does not define chemical composition or mechanical properties.

Q: Who typically uses it?

A: Steel producers, distributors, fabricators, mechanical and structural designers, purchasing/specification engineers, and standards/inspection bodies use this standard when specifying or verifying hot-rolled square bar dimensions.

Q: Is it current or superseded?

A: ISO 1035-2:1980 remains a published international standard; ISO’s catalogue indicates the part and related parts have been under periodic review and that a consolidated replacement (ISO/FDIS 1035) has been prepared to revise/replace the series—users should confirm the current status or latest consolidated publication before final specification.

Q: Is it part of a series?

A: Yes — ISO 1035 is a multipart series covering hot-rolled steel bars (Part 1: round bars; Part 2: square bars; Part 3: flat bars; Part 4: tolerances; etc.), intended to provide harmonized dimensional and tolerance tables across shapes.

Q: What are the key keywords?

A: Hot-rolled, square bars, dimensions, tolerances, sectional area, mass per unit length, ISO 1035.
