Full title and description

ISO 1175:1976 — Shipbuilding — Dimensions and sectional properties of aluminium alloy sections for marine use. The standard defines a set of standard aluminium alloy section shapes and gives their nominal dimensions and sectional properties intended for marine and shipbuilding applications.

Abstract

This technical publication specifies nominal dimensions and tabulated sectional properties (area, centroidal locations, second moments of area, section moduli, etc.) for commonly used aluminium alloy extruded and rolled sections designed for use in ship and boat structures. It was issued to promote interchangeability, consistent structural calculation data and easier specification of aluminium sections in marine engineering.

Scope

ISO 1175:1976 covered the dimensional series and the sectional properties of aluminium alloy sections intended for marine use — i.e., extruded and rolled profiles commonly applied in ship structures, superstructures and marine outfitting. The standard provided designers and manufacturers with a common reference for nominal sizes and mechanical-section data used in strength and stiffness calculations for hull and superstructure elements.

Key topics and requirements

• Standardized list of aluminium alloy section shapes and their nominal dimensions.
• Tabulated sectional properties: cross‑sectional area, centroid positions, second moments of area and section moduli relevant to structural design.
• Designation conventions for sections used in shipbuilding and marine applications.
• Reference data intended to support structural calculations and specification of marine aluminium profiles.
• Intended coordination with material standards and manufacturing tolerances applicable to aluminium alloys for marine use.

Typical use and users

Primary users were naval architects, shipbuilders, structural engineers working on aluminium craft, aluminium-profile manufacturers (extruders and rollers), classification societies and procurement/specification authors in the marine industry who needed standard section dimensions and properties for design, procurement and calculation. Engineers historically used the tabulated data as input for strength, stability and scantlings calculations.

Related standards

ISO 1175:1976 sits alongside other standards covering marine design, aluminium materials and mechanical testing. Users typically reference material-specification standards for aluminium alloys, test-method standards (tensile, hardness), and regional product‑standards (EN, ASTM) that govern alloy chemistry, tempers and manufacturing tolerances. Because ISO 1175:1976 has been withdrawn, contemporary projects typically rely on newer material/product standards and current shipbuilding design rules from classification societies.

FAQ

Q: What is this standard?

A: ISO 1175:1976 is an International Organization for Standardization publication that specified dimensions and sectional properties for aluminium alloy sections intended for marine (shipbuilding) use.

Q: What does it cover?

A: It covered a set of standard aluminium section shapes and provided tabulated sectional properties (areas, centroids, moments of inertia, section moduli and similar data) to be used in structural calculations and specification of sections for ship and boat construction.

Q: Who typically uses it?

A: Naval architects, ship structural engineers, aluminium-profile manufacturers, classification societies and procurement/specification writers in the marine and shipbuilding sector historically used the standard as a reference for nominal section data.

Q: Is it current or superseded?

A: ISO 1175:1976 is withdrawn (the ISO catalogue shows the edition published in August 1976 and a withdrawal recorded in June 1986). There is no ISO catalogue entry indicating an active direct replacement; users should consult current national/regional material and product standards and classification‑society rules for modern, authoritative requirements.

Q: Is it part of a series?

A: ISO 1175 is a standalone standard dealing specifically with aluminium section dimensions and sectional properties for marine use; it was produced under ISO/TC 8 (shipbuilding). Related work on marine materials, structural rules and testing is handled across several ISO technical committees and by national/regional standards bodies and classification societies.

Q: What are the key keywords?

A: aluminium sections, sectional properties, shipbuilding, marine use, ISO 1175, dimensions, section modulus, moment of inertia.
